Patch News – October 2019

Patch News – October 2019

I said in the last Patch News that September had started with great weather but finished with strong winds and rain. Well the awful weather continued into October and although we did have a few good days much of the month was pretty lousy. Undeterred by the rain some of the keener (or should that be more stupid) members still managed to mow the patch a few times and hopefully it won’t need to be cut again for a while as it’s now turning colder.One particularly horrible very wet and windy Friday afternoon only three of us were able to make it for mowing, but at least we were cheered up by Woody supplying cakes as it was his birthday. Thanks Woody.

Following the departure of the late lamented 473 and all of his mates the field stayed bullock free for the whole of the month. The young replacements have now moved into the lower field but they’ll probably go inside for the winter before coming to our field. That’s what we’re hoping but we’re keeping the fence in place just in case.

Probably as a result of the poor weather not many new models were flown in October but the regular pilots flew whenever possible and there were a few other things that kept us entertained anyway. One midweek day early in the month we were pleased to see a Gypsy Moth exploring the area. It didn’t seem to be aware of us at all but it flew several fairly low and close passes and stayed in the general area for a few minutes. Luckily Kryten was on hand with his decent camera and he managed to snap this photo despite the rather murky weather conditions.I took some rather poor quality video with my mobile which you can see in this month’s video. Later in the month, on one of the few midweek days of perfect weather, we were treated to a very low fly-by by what I think was one of the Solent Flight Ikarus C42’s from Lower Upham Airfield. They are often in the area when we are flying but rarely come very low or very close to us. On this occasion the pilot seemed to be practising engine out procedures as several times the plane came down very low with the engine idling before open the throttle and climbing away. Mostly it wasn’t close to us but on one occasion it came almost overhead and I managed to take some video.This photo is a screenshot from the video which you can see in this month’s video. Needless to say we quickly landed all models on both these occasions and didn’t fly again until we were sure they’d left the area.

We are continuing with the foamboard fun and I’ve lost count of how many there are now in the club, must be about twenty I think. Captain Slow and I seem to have got into the habit of flying in close formation and sometimes the inevitable collisions occur. These are always Captain Slow’s fault of course, I always do my best to avoid contact despite what he says! There is very rarely any damage from these collisions, sometimes a nick from the prop but almost never anything more. On the day of the Gypsy Moth visit we were practising our formation flying when Captain Slow managed to carelessly hook his Mig-29 tailplane into the dangling battery lead on my Sukhoi, very poor piloting by him I thought. Kryten snapped a couple of great photos, the first when we were in close formation shows the battery lead dangling underneath my Sukhoi, and the second when we were actually locked together.Of course we both immediately shut our throttles but then found there was a distinct lack of directional control which meant Kryten had to take rather sharpish avoiding action but all was well. This is how they ‘landed’.There was no damage at all to either model so once we’d managed to disentangle the planes we carried on flying. The things we do just to help Kryten get some decent pictures…

Dougal Entendre has put together another 3D model, an MX2 3D EPP from Hobbyking, exactly the same as Chuck Berry’s that I featured a couple of months back. It comes as airframe only so no motor, esc, or servos are included but most of us already have suitable electronics to hand anyway. It’s currently showing as around £45 on the HobbyKing website but I think Dougal said he only paid £35, a real bargain. This is what Hobbyking say about it: Its fuselage is torsionally very stiff yet light with loads of space beneath the long top hatch for your radio and power system. The wing is a one piece affair featuring EPP construction, a very accurate symmetrical aerofoil with 2 additional spars to minimise flex and twist. The control surfaces are something else – the elevator, rudder and ailerons feature a 3 layer construction (EPP-Depron-EPP) making for stiff surfaces and NO flex at extreme throws! Snap rolls ‘Snap’ and control response is instantaneous. The light – yet rigid – airframe adds up to one great flying 3D ‘foamy’. Waterfalls, harriers, flat spins, rolling circles this model has the precision to perform these and any other moves you can think of! Assembly of the airframe in a quick 10-15 minute process with the help of a little medium CA. The radio and power system layouts are very straightforward, the long top hatch making for easy access. This is a great model for general park flying and hard core 3D. You will be hard pressed to break this model, it will take hard knocks and just keep bouncing back every time! Dougal has fitted his MX2 out with the Propdrive 2830 1100kv motor that was previously in his now defunct Laius, a 40A ESC and a three cell 1500mAh lipo. At the moment the prop is an APC-style 10×5, but he wants to go up to at least a 10×6 or 11×5 as it could do with a bit more power and there was still 45% battery capacity left after a 5 minute flight. Dougal tells me that he stripped the plastic gears on the 9g elevator servo just with the aerodynamic loads, so he needs to replace that one with something beefier, and probably the rudder servo as well.1066 has (had?) a Hobbyking Sbach 3D EPP which is a variation of the same base model but according to 1066 the engine mount/front bulkhead (a weak point of the Sbach) is stronger on the MX2.  Dougal’s first flight with the MX2 looked very promising, I think it will be as good as 1066’s Sbach, judge for yourselves in this month’s video.

Captain Slow has now fitted some FPV gear to the Mini Skyhunter that he first flew back in July. That first flight was ‘interesting’ because the model had a drastic tip stall so Captain Slow has taken steps to eliminate it. He has moved the centre of gravity forward by fitting two 3 cell lipos instead of one and that seems to have solved the problem.The FPV gear consists of a Foxeer Predator Mini camera, an Eachine TD600 video transmitter, and Quanum Cyclops goggles. Captain Slow is slowly getting round to slotting in an SD card to record video of his flights but refuses to rush! He had several FPV flights in October and all went well, no problems with either the equipment or him flying it. He finds it better to sit down when wearing the goggles and he has a tendency to lose his balance. That’s understandable, both Dougal and I occasionally find ourselves a bit off balance at certain times although it happens less and less as we get more experienced. We only ever fly one FPV plane at a time which means there is often a spare set of goggles doing nothing so sometimes another club member will watch a flight to get the feel for FPV.In this photo Gentleman Jim was keeping an eye on Captain Slow while he explored the area with the Skyhunter.

1066 has been searching for a hotliner (fast aerobatic powered glider) for a some time now but he hasn’t been able to find anything he really likes, at least not at a price that he really likes. Eventually he bought a rather battered second-hand Multiplex Gilb on eBay and has spent some time tarting it up. I’ve not heard of the Gilb so I’ve done a bit of searching on the internet and discovered that Multiplex introduced the model way back in 1995. The wingspan is 2150mm, length 1070mm and all up weight is in the 2500-3200g range. It was reviewed in QFI (Quiet Flight International) in July 1995 but as I don’t have the magazine I can’t tell you what it says. On one of the forums someone was talking about various brushed motors and using 10-14 cells, ah yes, the old pre-brushless motor days with nicad/nimh batteries! 1066’s model came ready fitted with a Tornado Thumper 3536-06 1270kv outrunner motor and a 70A speed controller. 1066 is using various four cell lipos, mostly in the 3000-3300mAh range and the power is reasonable although he’d like a bit more. I’m not sure what prop size he’s using but he said he’d tested one with 2” more pitch and the current went up to 90A so he can’t fly with that one!He had to do quite a lot of work to the model to get it ready for flight and quickly discovered that more work was needed, it was well out of trim. I wasn’t present for the first flight but apparently the model was a real handful. After some more work it’s now flying pretty well although there’s still a bit to do to get it flying as 1066 would like. It’s pretty quick so not easy to video but I managed to get some footage which is in the video.

Captain Slow has also bought himself a second-hand Multiplex model, this one’s a Pilatus PC-6 Turbo Porter that he found on the BMFA Classifieds webpage. The following photos are all taken from the advert. The Turbo Porter is a moulded foam model that has the usual controls plus flaps and a scale sprung undercarriage with large wheels. It can be converted for operation from water with the addition of a float kit. The 1250mm span model comes fitted with a Permax 3530 1100kv motor with an 11×5.5 prop, a 40A esc, and 6 metal geared digital servos. The suggested lipo is a 3 cell 2100-2700mAh, a pretty standard size that we all have. The cheapest I can find it new online is £170 and some retailers list it at over £200 so I reckon Captain Slow got a bargain at just £75.I haven’t yet seen the plane for myself but Captain Slow says it’s in good condition and he just needs to change the esc connector and fit a receiver and battery. We should get to see it sometime towards the end of next year then.

I always feel poor old Kryten gets a bit of a rough deal in Patch News, he provides us all with some superb flying shots of our models but never gets any photos of his own models in action. My mobile takes excellent photos of stationary models and pilots, and it’s pretty good for video as well, but it’s just not up to the job when it comes to capturing flying shots. This was the best I could get of Kryten’s E-flite Apprentice:But I did manage to capture Captain Slow measuring Kryten’s spot landing attempt one day. It was an excellent spot landing but as an aside, why on earth has Captain Slow got ER embroidered on his socks?Is he still wearing socks he purloined when he was merely Acting Lance Corporal Slow all those years ago?

Dougal had an interesting incident while flying his Skyfun using FPV one day. On the second flight of the day I was Dougal’s spotter and the model seemed to be flying well but suddenly I could see something hanging underneath it.At almost the same moment Dougal said he’d lost power. He glided the Skyfun in for a deadstick landing and on the approach I realised it was the motor that was hanging down. When we reached the model we could see what had happened, the prop had thrown a blade and the ensuing vibration had snapped the metal mount. At some point the second prop blade had also broken and one of them had chopped the top off one of the fins as it flew off! The motor was left dangling by its wires and Dougal was lucky that it hadn’t pulled the plugs out from the esc wires, we would probably never have found it. I’m not sure if the motor mount is a stock item or a special Skyfun part but I expect Dougal will soon have it sorted and flying again.

It was good to see Gorgeous Gary on the last Sunday in October, he’s been absent for a while blaming holidays, work, and life in general. He brought along a couple of models, his foamboard Sukhoi SU-27 and his Ripmax Jive.Gary was slightly nervous having not flown for a while but the Sukhoi soon put a big smile on his face. The Jive was also ok although that strange dirty, noisy, smelly thing on the front seemed a bit reluctant to run at first.I was flying when Gary was trying to start it but I could hear comments of “There’s an answer to that” etc. How cruel, you’d never hear me saying things like that! It was all in good fun and the Jive was soon up and flying.

My Volantex Ranger 1600 is flying well on FPV and I made a few changes to it in October. The Ranger 1600 comes without an undercarriage although the 1200, 1400, and 2400 versions all have one. I wanted to use mine to practice FPV take-offs and landings so I fitted an undercarriage from another model. It worked well enough but the wire was too weak and bent on anything less than a perfect landing so I’ve now replaced it with one made of stiffer wire. It’s proved to be much better and has stood up to many touch & go’s and landings without bending. I have also fitted another FPV set-up whilst retaining the original one so I can choose which to use at any time. The original FPV equipment is all fitted inside the Ranger fuselage with the camera mounted in an existing hole under the nose. But the model also comes with a moulded foam insert that clips on in place of the usual canopy so I fitted the latest set of equipment to that. The second set-up consists of a Caddx Turbo Micro camera that I spotted in the Hobbyking sale for just £8.02 and a Speedy Bee VTX-DVR from Banggood for £11.92. So for just under £20 I got what has turned out to be a good quality camera and a transmitter that sends the video stream back to the goggles and also records the video onto a micro SD card, ridiculously cheap.The set-up works well and having the camera mounted higher up has proved to be much better as the original camera tends to pick up dew and grass cuttings on the lens during take-offs, not ideal. The higher mounted camera avoids all that and although it’s only around 100mm higher than the original it makes a surprising difference when taking-off, I can actually see where I’m going instead of just grass!

Time now for a few of Kryten’s excellent action photos:

Video time now and this one includes quite a bit of FPV footage from both me and Dougal. Please watch it full screen, it so much better with small models flying around.If the video won’t play for you please click HERE

A class of school children were taken on an airport tour and their last stop was in the control tower. They were given a talk by an air traffic controller who explained how everything worked and he then asked if there are any questions.
One lad says “Have you ever had a real emergency?”

Patch News – September 2019

As is often the case September brought a bit of an Indian summer and the beginning of the month glorious.Sadly the last ten days or so of the month turned very bleak indeed. The Foolish Five that turned up on the 22nd were caught out before even entering the field and sheltered in the barn for an hour or so before going home.Unfortunately you can’t actually see the torrential rain behind us in the photo but believe me it was there.

I will start with some sad news, Captain Slow’s favourite bullock 473 has moved on to pastures new. Well actually to a butchers, along with the rest of the herd. 473 had become such friends with Captain Slow that he would run to the gate when he heard the Captain’s car coming down the track. He was so reluctant to go that tried to hitch a lift…In an effort to console the tough, war hardened Captain the committee chipped in and bought him a keepsake.

The first model to feature this month is Dwayne Pipe’s TSR2 which has actually been around for a little while.It’s flown well lots of times but has also had its fair share of ‘abrupt arrivals’. Dwayne has been steadily improving the model and gradually increasing the thrust, but last time out it suffered a sudden total loss of power which Dwayne later discovered was due to the speed controller failing. This month it re-emerged after the latest rebuild.So the TSR2 now has an uprated speed controller to cope with more current and this time the flight went well until Dwayne was caught out by the strong wind when he tried to turn back towards the patch from downwind.  Unfortunately the TSR2’s nose went up too much which can be fatal for an EDF, they need to keep lots of air going through the fan. The model stalled and Dwayne was unable to stop it dropping into the valley. But it will return, Dwayne is excellent at repairing damage and I look forward to seeing it flying again soon. I was videoing at the time of the rather distant crash so you can see it in this month’s video.

But Dwayne Pipe wasn’t the only member to take a trip down the valley in September was he Dougal?!To be fair Dougal Entendre’s long walk wasn’t caused by a crash as such, he’d been doing one of his amazing sycamore spins with his Tomahawk but it refused to come out of it. The Tomahawk is a flying wing that Dougal has discovered will spin incredibly rapidly around its centre point if he gets the entry to the manoeuvre correct. But once in the spin the exit can be a problem and if Dougal can’t get it to come out it simply continues spinning all the way down to the deck. Fortunately it spins so quickly that the rate of descent is quite slow and it very rarely sustains any damage. Previously when it’s happened the Tomahawk has come down in the field but on one particularly windy September day it drifted well out over the valley and the photo opportunity was simply too good to miss!

In last month’s Patch News I showed you three new models that all belonged to Chuck Berry and in September he continued the trend and turned up with yet another one, this time it was a Great Planes ElectriFly Yak-55M.Apparently the M version of the Yak-55 was designed in 1989 with shorter and more tapered wings to give it a faster roll rate than the original 55 had. The Great Planes ARTF model is 1285mm span and is constructed from lite-ply and covered in Monokote. Chuck has fitted it with a Prodrive V2 3548 900kv motor, a YEP 80A esc and a 12×6 prop. The four servos Chuck used are Radient RDNA0079s, that’s not a make I’m familiar with at all. The manufacturer recommends using a 4s 2200 mAh lipo but Chuck is using 4s 2700mAh packs to extend the flight time slightly. I did the maiden flight for Chuck and found it to be an excellent flier. Chuck has now flown it quite a bit and says it has a slight pitch coupling with the rudder, nothing that a little mixing can’t sort out I imagine.

Sticking with similar 3D machines Mike Smith has treated himself to an FMS Sbach 342 and very nice it is too.The 1300mm span model comes as Plug and Play so Mike just had to fit a receiver and a 4 cell battery. The motor is a 3948 760kv brushless outrunner which is coupled to a 60A speed controller that has a 3A BEC and the propeller is a 3 bladed 13×5. I’m quite surprised by the prop size, the recommended set up for Chuck’s Yak 55 is a 4250 800kv outrunner fitted with a 2 bladed 12×6 prop. The models are almost the same size and the weights are similar with the Sbach being slightly heavier. There’s a big difference between a 3 bladed 13×5 and a 2 bladed 12×6 but both planes fly very well and appear to have plenty of power so what do I know!The four pre-fitted servos are all 17g and unlike the Yak the Sbach is moulded from EPO foam. Mike is using 3000mAh 4 cell lipos that do the job perfectly. You can compare the Yak and Sbach flights in this month’s video.

Away from the patch we had the PAM Skittles Evening on 14th September at the Barley Mow in Walderton. I had a great night and I think everyone enjoyed both the buffet and the bowling. It’s just a bit of fun but we do always present prizes to the best lady and the best man bowlers and this year, for the first time in the history of the club, a husband and wife won both. Congratulations to Bob and Bonnie Hill, for one month only we have Bob the Bowler!We also had a raffle and one of the many prize winners was Cameron Agate who wisely selected a tub of roses for his mum Angie. I have so say that he didn’t exactly look overjoyed with it!

Always on the lookout for a bargain Chas Butler picked up this Multiplex Stuntmaster for around half the new price.He spotted it on the stand of a dealer from Bournemouth while at the LMA show in Much Markle in September. The model was ready to go, just needing a receiver and battery adding. According to the specs it uses 3 cell 450mAh lipos, I wonder if Chas has got any of those or if he’s managed to squeeze in a larger one. It looks completely unmarked to me but apparently the dealer dinged a wingtip on his sales table so he knocked another £5 off the price. Actually, if you zoom in on the photos you can just make out a very small ding on the right hand wingtip. The Stuntmaster is designed to be flown either indoors or outdoors in very light wind conditions and the weather hasn’t been calm enough to fly it outdoors since Chas bought it. But no doubt he’ll fly it soon and discover just how good (or bad!) he is at 3D flying. The Stuntmaster is made from Elapor (the Multiplex version of EPO foam) with carbon fibre reinforcements, has a wingspan of 870mm and weighs just 350g (12.3ozs). The ready fitted hardware consists of a Permax 2206 1050kv outrunner, a 20A esc and three 8g servos. The 9×5 propeller is held in place by a rubber O-ring so any unscheduled arrivals shouldn’t damage the motor shaft, not that Chas will have any unscheduled arrivals obviously… Both ailerons are operated by one servo mounted centrally in the fuselage above the wing, an arrangement that is pretty unusual on outdoor models these days but maybe it’s common on indoor ones. Looking at some of the online videos of the Stuntmaster it’s a very capable model that can do just about any 3D manoeuvre you can think of, I look forward to Chas demonstrating them for us!

Gorgeous Gary has been working hard on his latest project recently, a Goldberg Anniversary Edition Piper Cub. It’s a proper builders’ model and comes with a 33 page manual containing lots of photos and instructions. The manual mentions die cut parts but looking at Gary’s photos they seem to be laser cut so I assume the kit has been updated. It can be built as either the standard or clipped wing version and Gary has opted for the clipped wing one at around 1715mm span. Gary being Gary, he’s fitting an OS Max 65 I/C motor to it (I can hardly bear to type such a thing!) so it should certainly have plenty of power. He currently trying to source a Pitts style muffler for the engine so he doesn’t have an ugly silencer hanging outside the cowl. There’s an answer to that Gary…! The finished weight should be around 7.5lbs. It looks to be coming along nicely so it shouldn’t be too long before we see it flying.

Certainly the most challenging model to appear this month was Catapult King’s Fairchild Republic A-10.It’s a totally scratch built twin ducted fan mode with retracts, not an overnight project, in fact about a year. This is what Catapult says: Basically I had two 10 blade 50mm EDFs that were destined for the F14 I started ages ago, I also had some retracts that I couldn’t use on the F14 and thought I would like to do a model using both so up came the idea of an A10. I found a 3D view picture and blew it up on a printer until I had a size that would fit the motors and printed it out. From the blown up version the model was basically made up as I went. The main wing didn’t take too long except it took a while to work out how to install the retracts as this was my first time using them. The tail/elevator sections came next followed by the fuselage, all the time thinking about where the electrics etc. would go. The nose wheel and doors and how to sequence them proved to be a pain. It’s mainly made from balsa with ply to strengthen and Depron to lose weight where I could. However, eventually I came up with a reasonable looking plane but I thought it was overweight which, as it turns out, it appears to be. The power train is two 10 blade EDFs which according to spec provide 650g of static thrust each, the model unfortunately has come in at 1.55kg flying weight. It uses a single 2650mAh 4s battery (all I’ve got) and good old HK 9g servos all round plus the heavy retracts. I’d hoped that once in the air the motors would be more efficient and at least it would fly, wrong! I think Catapult is being too hard on himself and personally I don’t think the problem is simply lack of thrust on an overweight model. I wonder if the wing/tail incidence is correct and also maybe the thrust line. You can see the attempts at flight in the video, it doesn’t look like a lack of thrust to me. But Catapult will persevere and I reckon he’ll get it sorted, after all he’s already had success with some pretty outlandish models.

Back to Dougal Entendre now. We’ve all had the warnings drummed into us about not using a mobile phone while driving but apparently Dougal didn’t realise it applied to model flying as well! He wasn’t actually intending to use his mobile as a phone, he wanted to use the timer on it to see how many loops he could do in one minute for the comp.In the end it was irrelevant as he longer had a competitive model to try it with anyway. RIP the Laius. Just to rub salt into his wounds I then proceeded to take the lead in the comp with 29 loops but no doubt he’ll have another attempt with a different model. He cheered himself up by ordering a new FPV camera, a pretty red one.Of course it’s not just the colour that’s different, this one has a 1.8mm focal length lens and his existing one has a 2.5mm lens which means he’ll have a wider field of view (FOV). It’s always good to experiment.

Kryten took some amazing flying photos for us again this month, here’s a selection for you to enjoy:

Video time now and this month it includes footage by Captain Slow and Dougal Entendre, thanks chaps. Please watch the video full screen, it’s so much better with small models flying around:If the video won’t play for you please click HERE

And finally, with thoughts of Captain Slow and bullock 473:
Why wouldn’t the farmers invest in flying cows? Because the steaks would have been too high…

Patch News – August 2019

August has come and gone and so have the bullocks. As expected they returned to our field early in the month but have now moved on again. Woody seemed to prefer staying with the bullocks rather than joining the pilots. The bullocks’ departure may have been helped by a car smashing into the gate post and preventing the gate closing properly. One unkind wit was heard to mention that they didn’t realise Basher Bob drove a small red Peugeot…Farmer George has ‘topped’ the field, and according to Google Regular topping helps to maintain a good quality grass sward which has many benefits for both your land and your animals. Fortunately he left the patch alone and our regular mowing is doing an excellent job of maintaining a good quality grass without topping. We can’t see any sign of the topping from ground level but it’s very noticeable from the air when flying FPV.The weather was good for most of the month although one Sunday was lost due to wind and rain. As I was away that week I didn’t care! The August Bank Holiday weekend saw record breaking high temperatures and light wind, perfect for us and for the BMFA Nationals being held at Barkston Heath. The Nationals even made the BBC! It’s HERE

The hot weather brought out lots of bugs and I spotted a cute little grasshopper checking out my Volantex Ranger.Unfortunately Dougal Entendre got bitten by a horsefly and ended up with a very swollen infected leg that prevented him from walking up to the patch for a while. Several courses of antibiotics sorted him out eventually.

Lots of new models made the most of the good weather and the first three I’ll feature all belong to Chuck Berry.His first is an MX2 from HobbyKing, a 955mm span 3D model made mostly from EPP. It comes as an ARF so Chuck added a Turnigy Aerodrive 1050kv motor, a 30A HobbyKing speed controller and a 10×4.7 carbon fibre prop.The battery used is a surprisingly small 3 cell 1300mAh lipo. 1066 has been flying one of these for a while and found it to be an excellent 3D model. Chuck’s also flies very well so we expect to see him prop hanging it very soon.

Chuck’s second new model was yet another foamboard Sukhoi SU-27 from HobbyKing. I included a couple of photos of the Sukhoi last month but Chuck had found a problem with one of the linkages so it hadn’t flown.He is using a Turnigy D2205 2300kv motor with 30A HobbyKing speed controller and a 3 cell 1300mAh lipo.Like me Chuck has fitted a single rudder to one of the fins, it works well and Chuck is able to do the high alpha manoeuvres well. These foamboard models bring out the hooligan in pilots and the target often seems to be Captain Slow. But unlike my gentle touches Chuck went the whole hog and took half the fin off Captain Slow’s Sukhoi.Well done Chuck, keep it up! Sadly it didn’t quite all go Chuck’s way though, this was one of his ‘landings’.But the foamboard range of models are all surprisingly tough and there was no damage to the Sukhoi this time.

And last but definitely not least of Chuck’s new fleet is an FMS Edge 540, a 1320mm span Plug’N’Play model.It comes ready fitted with an FMS 3948-KV760 motor turning a 3 blade 13×5 prop, a 60A speed controller and four 17g metal gear servos. Chuck is using 4 cell 2700mAh lipo packs which give a flight time of around 6 minutes. It’s certainly well rated and seemed to fly very nicely when I did the test flight. It needs Dougal Entendre or 1066 to properly check out the 3D capabilities but it did everything I tried easily enough. Bad news if you’d like one of your own, I’m afraid it’s been discontinued. You can see all three of Chuck’s new models flying in this month’s video.

It’s Bob the Builder’s turn now, he’s got himself a two metre span Volantex Phoenix 2000 V2 glider from HobbyKing.I can’t find anything that lists the differences between the V1 and the V2, the most obvious sign is that the V2 has a very nice wheel mounted in a new fuselage moulding. Apparently the tail has been redesigned to make it stronger and it comes with flaps as standard, I think the flaps were extra on the V1. The fuselage is made from blow moulded plastic and the wings and tail are EPO foam. Bob flew the model in its’ original Plug’N’Play form but he very quickly decided he wanted more power and swapped out the original 28mm 1050kv motor for a much more powerful one.After doing some research he chose a Turnigy SK3 GliderDrive of 1400kv. The GliderDrive motor is effectively an outrunner in a can meaning that the outside of the motor does not spin so it’s ideal for the slim nose of a glider. At the moment Bob is still using the original 10×6 folding prop and he’s changed the original 30A esc to a 50A one.The previous motor gave 300W on 3 cells, the new one gives 450W on 3 cells and 700W on 4 cells, although he hasn’t flown it on 4 cells yet. Bob has also added more colour to both the top and underside of the wings.

Next up is another ‘proper’ model builder, John Warren. This time John has built a 66inch span Jocasta from a plan in RCME in October 2014. The 66” span all built-up high wing model was designed by Jim Newbury and John has equipped his with the 4-Max recommended set-up consisting of a 3547 800kv motor, a 60A esc, and a 12×6 prop. It runs on a 3 cell lipo and pulls 29A at full throttle, giving around 250W. A 3 cell lipo is nominally 11.1v so at 29A the wattage should be around 320W, so 250W is probably a good average figure with a partly discharged lipo. The model weighs almost 5lbs so we thought it might be a bit marginal with that power but it takes off nicely and happily stooges around on half throttle with no problems. Dougal Entendre did the test flight which was fine until the battery died unexpectedly early. He got the model safely back on the ground with no damage and our thoughts were that perhaps John’s batteries were past their best and unable to deliver the power they should but subsequently the flights have been much longer and the packs have had plenty left in them so maybe that first one just hadn’t received a full charge. John has made a lovely job of the Jocasta and it flies well, a perfect model for John in fact.

Back to the foamboard jets now, Dwayne Pipe has put together an SU-27 and it’s…just like all the others!Well not quite actually, I asked Dwayne for some info on the model and this is what he said: It’s a pretty standard setup. 2200kv HobbyKing Turnigy 2826/6 motor with a HobbyKing 30A esc and a 6×4 prop powered by a 1300mAh battery. To reduce the noise, as well as the standard enlarging of the propeller slot, I glued some profiled balsa to the foamboard edges that face the prop wash. This was intended to have two effects: to provide extra strengthening to reduce vibration on the rear of the aircraft, and to stop the formation of Karman vortices which will generate vibration around any flat facing surface, like the edges of the foamboard, in the flowstream. (Look them up on Google). How effective this was remains to be seen.Well having seen (and heard) it fly I can safely say it’s certainly not any louder than the other SU-27s, not sure if it’s any quieter or not but it has to be worth trying. I might do the same on mine to see if I can notice a difference.

Chas Butler has become a regular attendee at the flying field again and is building up his fleet of models. His latest one is a Multiplex Extra 330SC designed by multiple world champion Gernot Bruckmann. The Extra is available in either kit form (ARTF) or Receiver Ready (RR). The RR version comes fitted with a Multiplex PERMAX BL-O 3520-920kv motor, a 55A esc, and four Hitec HS-82MG servos. At the time of writing it’s only had one flight and Chas was being very careful with it especially as he found the controls extremely sensitive. You can see it in this months’ video. This is what Chas has to say about his: Mine is a Receiver Ready version requiring just a receiver and a 3 cell 30C 2600mAh flight battery. I’ve installed a 6 channel JR PROPO DFA receiver and the battery used was an Overlander one of 2900mAh capacity. Since the maiden flight I’ve reduced the Aileron travel by 50% on rates with 50% Exponential and the Elevator by 25% on rates, also with 50% Exponential.
I’m just waiting now for the chance to fly it again. The first flight was very nervy but I’m sure that next time I will be more confident as that was the first flight for some years with any plane quite so responsive.
I’ve seen Gernot Bruckmann flying one of these and know what a superb model they are so I expect to see Chas performing all kinds of crazy manoeuvres very soon.

The last new model is a Pichler HiSpeed belonging to 1066. It certainly looks nice but 1066 isn’t very happy with it. He bought it from RobotBirds and this is what their website says about it. The HiSpeed is the latest release in the Speed series designed and developed by Pichler, Germany. While this model is designed to offer breath-taking high-speed flights in excess of 200km/h it is also capable of slow-speed fly-bys and landings. This version is supplied as Plug-and-Play (PNP) needing minimal assembly. It is 95% pre-built and includes the recommended Pulsar C5066 P20-1300 brushless motor, 40A brushless ESC, fast 9g servos and a high-performance spinner/propeller. The main gripe 1066 has is that all the electrical parts (motor, esc, servos) weren’t already fitted, they were just included loose in the package. Also, although the website says it needs a 3 cell lipo and the esc is only rated for 3 cells the instruction say to use 4 cells for the best speed. The model flew nicely on the first flight and appeared to groove very well but it really wasn’t very fast, certainly nothing like 200km/h. For the second flight 1066 fitted a larger prop and it was a bit faster but still not really what he was hoping for. He doesn’t have any 4 cell lipos so if he wants more speed he’ll have to buy some and also swap the esc for one that can handle 4 cells. Never mind, it looks good in the air and it’s quite fast enough for most PAM members! Check it out in this months’ video.

Kryten took lots of excellent flying photos with his quality camera this month, here’s a selection for you: Other photo and video contributors this month were Dougal Entendre and Captain Slow, thanks chaps.

Patch News – July 2019

In the June edition of Patch News I said that the June weather hadn’t been up to much and that maybe July would be better. It was, much better! Much of the month was hot and sunny and we had a new UK record temperature towards the end of the July. The great weather meant some good turnouts at the patch and the Farts have been cutting the grass regularly, although it hasn’t grown much this month, and the patch is now in superb condition.  The bullocks moved out early in July and haven’t yet returned but I doubt it will be long. Captain Slow has been missing his favourite, number 73, so 1066 snapped this keepsake and sent it to him via the WhatsApp group:

The first new model I’ll feature this month is this profile Edge 540 in Castrol colours. It belongs to Dougal Entendre and was put together by his son Cameron from a kit that Dougal bought several years ago. I was away on the day that Dougal tested it and the only information I have is that “it flew ok”. All I can go by is the photos but I have to say that it’s one of the ugliest models I’ve ever seen! I Googled it and found several photos of the full-size original and I think that’s pretty ugly as well so it must be the colour scheme.

The same day the Edge 540 flew Woody brought along a much prettier model, his new E-flite F-15. This is what the E-flite website says: The E-flite® F-15 Eagle 64mm EDF jet is a replica of the world-renowned air superiority fighter flown by the U.S. Air Force. It’s equipped with a 4S-compatible brushless motor and a 40-amp ESC that are matched to an 11-blade fan to deliver fantastic speed, thrust and a turbine-like sound. The factory-installed power system and servos help make it quick and easy to assemble the lightweight yet durable EPO airframe with bolt-on wings so you can be flying in less time than it takes to charge a battery. Optional-use fixed landing gear with a steerable nose wheel is included so you can taxi, take off and land on runways, or you can leave the landing gear off for improved performance plus easy hand launches and landings on grass. You can also fly with or without the wing-mounted drop tanks and missiles depending on the look and handling you prefer. And it all adds up to deliver one of the easiest to enjoy and easiest to fly Eagle models ever!

Woody bought the Bind N Fly version that comes with a Spektrum receiver with AS3X gyro and Safe Select technology: This is the first high-performance F-15 model equipped with exclusive Spektrum® AS3X® and SAFE® Select technologies. AS3X works behind the scenes to smooth out the effects of wind and turbulence to deliver a locked-in feel that makes it seem like you’re flying a much larger jet. Optional-use SAFE Select offers pitch and bank angle limits along with automatic self-levelling that can be turned on and off at the flip of a switch making this the easiest to fly Eagle yet! And if you don’t want to enable the SAFE Select features, simply bind the receiver normally and only AS3X will be active.

Dougal did the test flight and with the Safe technology switched off and a 4 cell lipo the F-15 didn’t get away from the launch, the thrust just seemed to push it down more than up elevator could overcome. So Woody changed to a 3 cell lipo to save nose weight and move the centre of gravity rearwards a little and Dougal managed to get it away from the launch and flying nicely. Since then I’ve flown it several times and found that with Safe switched on it goes away from the launch easily but is then a bit too limited in roll to fly with any fun. So I’ve been turning Safe off straight after the launch and flying it normally when it performs really well. It will happily cruise around on half throttle and has plenty of power for the more exciting stuff on full throttle so I can’t really see why you’d want to use the suggested 4 cells. Woody has flown it with Safe switched both on and off and found it’s certainly easier to handle with it on but it will really only fly quite large circuits around the field as the roll is limited a bit too much.I’ve found that the fan alignment isn’t quite right and opening the throttle pushes the nose down which is ok in normal flight but makes landing slightly awkward, you have to be prepared that when you shut the throttle the nose will go up and you need to add some down elevator.  It might be possible to correct it with an elevator/throttle mix but we haven’t tried it yet. It looks great in the air and my only complaint is that it’s too quiet! You can barely hear the fan at all and it’s much quieter than many prop driven electric models. See it for yourself in this month’s video.

Captain Slow lived up to his nickname in early July when he launched Dougal’s Tomahawk pusher motored model, he didn’t move his hand away quickly enough and his knuckle was nicked by the propeller.Fortunately it wasn’t serious, it could have been much worse, but it does serve as a warning to be extra careful when launching pusher models. It also proved the worth of the first aid packs that all members are issued with.
You do have yours with you at the patch don’t you? They are of little use left in the car…

While I’m on the subject of Captain Slow I’ll show you what he’s done to one of the fins on his foamboard Mig-29.We’ve been enjoying lots of really close formation antics with the foamboard jets, they’re almost indestructible and are very cheap anyway. With their mid-mounted motors even if the planes nudge each other the props rarely touch anything but on one occasion Captain Slow’s Mig obviously climbed up into the path of my SU-27.
I find the abusive adornment totally uncalled for when I was the completely innocent party…possibly…

On 11th July Dwayne Pipe ran the annual Chuck Glider Competition at Buriton recreation ground before the start of the club meeting. The comp is always popular and we had a reasonable turnout on the warm and almost windless evening. There were six rounds flown with the total time of all six flights producing the score, no discards allowed. The winner of the comp, obviously the most prestigious, demanding, and skilful comp of the year, was Andy Palmer (Colin Cowplain) with Mark Agate (Dougal Entendre) second, and Percy Vears (Ron Vears) a very close third.

We were pleased to see Mike Critchley visit the field after being absent for a few months while he was ‘working’ at sailing around the Caribbean and Norway. As you can imagine we were all very sympathetic to the poor chap!He brought along a new Multiplex EasyGlider for me to trim out and I discovered that it didn’t need a single click of trim on any surface. Mike already had an EasyGlider when he joined the club but I think he damaged it and decided to treat himself to a new one. As well as flying with us Mike also flies with MVSA and the EasyGlider is an ideal model for slope soaring as well as flat field flying.

Back to Captain Slow now, he’s actually finished assembling his Sonic Modell Mini Skyhunter, that must be a record.He bought the model from Banggood where it is available from their UK warehouse so there’s no waiting for shipment from China, no import duty to pay, and less risk of it being damaged in transit. I pictured it last month in its ‘naked’ state but now it’s complete and flying. The Skyhunter is 1238mm span and is moulded from EPO foam with carbon fibre tail booms. Captain Slow has fitted a Turnigy Aerodrive SK2826 1130kV motor and runs it on 3 cells although he actually fits two 3 cell 2200mAh packs to get the correct centre of gravity. There is loads of room for two packs and he could connect them in parallel to double the flight time but it flies for ages on just one anyway. The first flight was fine until I asked Captain Slow to do a nice low and slow pass for me to video and he discovered that it tip-stalls quite easily. It took everybody by surprise, not least of all Kryten who had a close-up view of the Skyhunter while Captain Slow regained control! But no harm was done and the centre of gravity has since been moved forward which has largely tamed the tip-stall. The model is designed as an FPV platform so no doubt Captain Slow will be fitting his gear into it very soon.

Gentleman Jim has bought a Parkzone Wildcat. Yes I know he’s already got a Parkzone Wildcat but now he has a new one. Jim bought the first one at one of the Blackbushe model shows a few years ago for a much reduced price.If I remember correctly it was just the foam parts, no motor, esc, or servos were with it so he sourced those himself. It flew very well right from the start and has served him well despite having a few minor hiccups along the way. When Jim asked me to launch it in July I thought he’d done some general tidying up and repainted it but apparently not, he’d seen that Sussex Model Centre had some new ones so he splashed the cash and treated himself.I believe this one was Plug and Play, so it came complete with everything except the receiver and battery. The motor is described as a 480 size brushless outrunner of 960kV and it has plenty of power for the 975mm span model. So how does it fly? Er…just the same as Jim’s first one really, very nicely indeed. See it in action in this month’s video.

Dougal Entendre has put together another model to further his FPV flying experience, a Skyartec Skyfun. It’s Dougal’s second Skyfun and the cockpit is from his original one which has been kicking around in his loft for a few years. You can tell it’s old, that yellow tinted canopy isn’t tinted, it’s just old! Following the cutting of Captain Slow’s hand Dougal was concerned about launching the pusher motored Skyfun safely so he decided to make a take-off dolly. He spotted a child’s toy trolley at the local tip, dug deep, and parted with a whole £1 to secure it.After many long hours of engineering design he finished up with this, the All-Terrain Tranny Agate Trolley Dolly: Does it work? No! You can see the attempts in the video, so far none have been successful but it’s provided loads of fun for us. However, the Skyfun hand launches perfectly well and nobody has caught the propeller although Captain Slow hasn’t launched it yet… One of the trolley dolly attempts knocked the FPV camera off it’s mounting so Dougal taped it out of harm’s way inside the discoloured canopy but found the view wasn’t quite clear enough to fly FPV!The Skyfun flies well, it’s fast, agile, and much nicer for FPV than the Tomahawk. But Dougal has to be careful when chasing other models, the speed difference can be great as he found when he almost bashed Basher Bob’s Calmato.Don’t worry Dougal, for a small fee Patch News will blame Basher Bob (or anyone else you’d like) every time.

Chuck Berry has built a Sukhoi SU-27 and joined the foamboard jet jockeys. Well almost, he had a problem with the linkages prior to flight so it hasn’t actually flown yet but Chuck has since sorted the problem so it will fly very soon. The mid-motored jets have highlighted the fact that many people are unsure which way round the prop should be mounted. The golden rule is that the lettering on the always faces the nose of the plane. It doesn’t matter if the prop is a tractor or pusher, or if the motor is at the front, middle, or back of the model, the lettering ALWAYS faces the nose. The direction of rotation obviously depends on the type of prop but the golden rule never changes.

Chuck has busily accumulating a set of FPV gear and has bought one of these, a ZOHD Dart from Banggood.It looks like it could be a bit of a handful to me but it gets good reviews so I hope I’m wrong.

I’ve also been flying a new model in July, a Volantex Ranger 1600 that came from HobbyKing. I bought one for the big raffle a few months ago and was impressed by what I saw in the box. It has a plastic fuselage and foam wings and tail, reinforced with carbon spars. The 1600mm wings simply clip in place and are easy to remove for transport. The model comes ready fitted with a 2212 1400kV motor, a 30A esc and four 9g servos so all you need is a receiver and battery. The suggested lipo is a 3 cell 2200mAh but I’m using some old 3 cell 4000mAh packs and, reading the reviews, some people are using even bigger packs. It’s designed to take FPV gear but is an excellent flier anyway if you don’t want to fly FPV and will do all the usual aerobatics. I fitted mine with an undercarriage as I want to try some FPV landings with wheels (I’ve only belly landed FPV up to now). Adding the UC was an easy mod, I simply cut a hole in the underside, fitted a ply plate with hot melt glue, and screwed a wire undercarriage to the plate. It works well and the Ranger is good for touch and go’s as well as loops, rolls, inverted flight and so on as you can see in the video. I haven’t had a chance to fit the FPV gear yet but will get it done in the next few days.The Ranger is available in various sizes, HK only list the 1600 and 2000 versions but Banggood also have them with 1200, 1380, and 1980 wingspans, and those the last three come fitted with undercarriages included.

Woody got bored with his old Wot Trainer trainer when he damaged it a while ago and passed it over to Captain Slow who has now repaired it and re-motored it with an AXI 2820/10 that he’s has since about 2003.The model needs some nose weight so Captain Slow uses two 4 cell 2200mAh packs in parallel giving a capacity of 4400mAh. With an 11×7 propeller the motor pulls 40A and produces 620W. The Wot Trainer has a 1660mm span and a 270mm chord so there’s plenty of wing area to carry it’s 3kg weight and it will cruise around at half throttle.

Dougal snapped this photo of 1066 at a flying session that I missed. Later I asked 1066 what had happened and he said the battery suddenly died when he was prop-hanging at very low level. Well he would say that wouldn’t he!

I don’t have much in the way of flying shots this month but here’s an FPV one from Dougal which he describes as a close encounter of the inverted kind, one from Captain Slow of Dougal’s new Edge, and finally a Paritech Viper that has absolutely nothing to do with the club but I found it on another website and I simply love it!

Video time now and this month it includes contributions by Dougal Entendre, Captain Slow, and 1066. Please watch it full screen, it so much better with small models flying around:If the video won’t play please click HERE

When I returned from holiday, my suitcase didn’t arrive in the baggage area so I went to the lost luggage office.
I explained to the woman there that my case hadn’t turned up on the carousel. She smiled sweetly and told me not to worry because they were trained professionals and that I was in good hands. 

“Now,” she asked, “has your plane arrived yet?”

Patch News – June 2019

Well June has come and gone but if anyone was expecting summer they probably missed it. We did have some hot days at the end of the month but it was always quite windy. Not really what we would hope for in ‘flaming June’, maybe July will be better. The bullocks returned halfway through the month but they hardly ever bothered us.They have learnt not to touch the fence and if we put one round the pits area they avoid that even though most of the time it’s not actually turned on. Captain Slow’s favourite (number 73 that featured in the caption comp) has become even more friendly and actually wanders over to see him and be stroked now. Two words John: Beef burger. The patch is in great condition and has been mown regularly by the FARTS. Dougal Entendre seems to be taking things a little too seriously and was genuinely seen trimming around the box with a pair of scissors!

I’ll start the June report with an incident that actually happened on 31st May. This photo shows rather unusual damage to Dougal’s FPV Tomahawk flying wing. Note the chewed up aileron and fin and lack of propeller.Dougal had been following John Warren’s Sunday Flyer, a nice steady biplane that’s easy to follow but it’s fairly slow and Dougal inadvertently overtook it. The trouble with FPV is that once you overtake something you have no idea where it is, you can only see forwards, so when he throttled back to allow the Sunday Flyer to get in front again he didn’t realise he was in effect reversing into it! The impact did nothing to John’s model but its propeller inflicted the damage you can see on the Tomahawk. The FPV video captured the action and this photo taken from the video shows the moment the prop came off! I’ve rotated the photo 180 degrees, the model was actually inverted. The Tomahawk spun in to the deck, fortunately without further damage, but John’s Sunday Flyer carried serenely on as if nothing had happened. You can see it all happening in this month’s video.

Staying with FPV for a while Captain Slow re-positioned the FPV gear in his TwinStar after the initial couple of flights in May to make it a more user friendly layout, it was all a bit fiddly to access before but it’s much better now. The TwinStar has had dozens of non-FPV flights with no problems and seemed an obvious choice for a first FPV plane. The model is unusual in that it has old fashioned brushed motors rather than the now normal brushless outrunners.  That means it also has to have speed controllers suitable for brushed motors, again rather old fashioned items. When Captain Slow started flying it with FPV gear he suddenly found he was losing control and it seemed likely that it was just him not being used to flying with goggles although he thought something was wrong.Having come down near Harper’s Oak on one flight, fortunately with no damage, he asked me to take it up. All was ok at first but when I got a bit more adventurous I suddenly lost control. I throttled back and regained control but when I opened the throttle again I lost control again and the TwinStar crashed. It was damaged but repairable but we couldn’t work out what was wrong until Captain Slow did some tests at home and discovered that the BEC in the speed controller could only handle about 1A so as soon as more load was put on the servos the radio shutdown until the load was reduced. It’s odd that the problem had never showed up before fitting the FPV gear, we can only think that the extra load plus probably more use of the servos and higher throttle settings for FPV tipped the balance. Pre-FPV Captain Slow only ever really stooged around very gently, as is his wont, so presumably he never hit the limit of the BEC. Anyway he’s now putting together another model, a Sonic Modell Mini Skyhunter which is designed for FPV.This was how it was coming along mid-June, should be ready sometime in July…2025.

Iven has been splashing out lately…quite literally, he’s bought himself an Ares Gamma along with a set of matching floats and also a set of floats for his E-Flite Apprentice. Iven keeps a boat on the Thames that he visits most weekends during the summer and he thought floats would be an ideal way of flying while he’s there. Bearing in mind that he’s only just learnt to fly and passed his ‘A’ cert the floats have so far proved a step too far for his abilities but he’s getting there. In the meantime he’s been flying ashore, alongside the Thames, mostly successfully. He’s found that the Gamma is really only suitable for light winds and it becomes difficult to control in much of a breeze.He’s also bought a couple of the tiny E-Flite AS3X (3 axis stabilisation) models, the latest one being a UMX Timber.It’s 700mm wingspan, has the usual 4 channel control plus flaps yet only weighs 121g (4.3oz). It has a ‘brick’ style 6 channel rx/gyro/esc/2 servos in the fuselage, lightweight aileron servos, and a centrally mounted flap servo. The radio and 3000kv motor are powered by a 2 cell 280 mAh lipo battery which also powers the LED NAV lights, landing lights, wing-tip strobes and beacons so it should be ok for night flying. This tiny model has the lot!It also has optional plug-in leading edge slats just in case the flaps don’t slow it down enough for you.

Of course landing in a tree isn’t something that only happens to beginners…is it Dougal?!Dougal’s incident happened one very showery Sunday morning when some of us dashed from the barn during a brief dry spell and flew just east of the patch. I’d just pointed out to the others that we had positioned ourselves directly downwind of a tree when Dougal did his signature low inverted pass straight into the tree! Once we’d all stopped laughing 1066 went into tree climbing mode and managed to safely retrieve the undamaged Sticky. We’ve had Harper’s Oak for many years, now it seems we also have Dougal’s Deciduous!

I was away for a few days in early June but Captain Slow took some photos and video of some new models brought along by Newbie Nick and Matt Takhar. They both have Precision Aerobatics Addictions and when I asked Nick about them he said his is the larger Addition X finished in green covering and Matt has a little pink one! The Addiction X is 1270mm span and is powered by Thrust 40 motor connected to a 45A esc and a 3 cell 2200mAh lipo. Matt’s little pink one is 1000mm span and uses a Thrust 20 motor, a 30A esc and a 3 cell 2200mAh lipo. Looking at Captain Slow’s video they both performed very well, I’ve included some snippets in this month’s video.

Matt’s other new model is an Extreme Flight Laser EXP V2. It’s 60” span and according to the website it weighs around 5.5 – 6.0lbs. Matt hasn’t sent me any details yet but I know he’s swanned off to New York for a few days muttering some pathetic excuse about work so I suppose he can be forgiven. The stock set-up uses a Torque 4016/500 MKII Outrunner, Airboss 80 esc, a Xoar 16 x 7 prop, and a 6S 3300- 4000mAh lipo. I forward to seeing  the new models myself and will hopefully get some more info and video soon.

Captain Slow had an exciting moment while flying his Extreme one morning, there was a sudden bang and the motor ripped out! He managed to land without further damage and retrieved all the parts that came off.The model comes with the motor pre-installed, clamped in place between two pieces of foam but Captain Slow found a distinct lack of glue around the area, a problem that he has now rectified with copious amounts of sticky stuff!

Norwegian Nick can always be relied on to build interesting models and his latest is an English Electric Lightning. This is what Nick says about it: I had some scraps of Depron left over from earlier projects so I looked through some old Q&EF mags and found this Lightning and thought I would have a go as you do. It’s built from a free plan in the July 2009 mag designed by James Rutter. It’s a profile twin edf Lightning with a wingspan 16in, length 25in and weighs 8 1/2 oz. The two fans are GWS 40mm run by a pair of Feigao motors. The escs are 10amp run off a single 850mAh 3s lipo.
After having an intermittent power problem I found that the cable to one of the speed controllers was hanging by a thread. Repaired now and works fine. Also I have swapped everything over so the battery is on the right hand side which I hope will stop the left turn on launch. 
As Nick mentions there was a dodgy esc connection and when hand launched the model went to the left and plonked down in the grass. Not sure how much of it was caused by the connection and how much was due to most of the weight being on the left hand side of the fuselage. The connection problem prevented a second try that day but I’m sure it will be fine next time out, should look great in the air.

The foamboard fun continues and both Woody and Bob the Builder have put together new Sukhoi SU-27’s. We’ve been enjoying lots of close formation flying with up to four in the air at once and of course the inevitable touches sometimes occur. I’ve also managed to land mine on top of Captain Slow’s a couple of times!But the foamboard is remarkably strong and with the mid-mounted motors the props rarely hit anything so virtually no damage is done. Although Captain Slow did manage to make a few cuts in my Sukhoi the other day…the swine!

Early in June decided I needed an FPV model that was a bit more taxing to fly than my Sukhoi. The Sukhoi was a great choice for learning to fly FPV but I wanted something that was a bit faster and not quite so easy to handle and land. Looking around my vastly overcrowded model room I spotted my Delta, built from Correx several years ago as one of the annual club builds. It was always a good flier and quite fast but equally, being a delta, lands reasonably slowly. As it was built from around £2.50’s worth of Correx and has had hundreds of flights it’s also regarded as disposable, perfect for FPV in fact. So I swapped the FPV gear into it, the main difficulty being that having the motor at the front meant I had to fit the camera out on the wing to avoid looking through the propeller. That hasn’t proved to be a problem and I quite like being able to see the prop spinning (or not) through the goggles. Ever since Dougal and I started flying FPV we have been hoping for a day with low cloud to explore but it hasn’t happened…until one morning late in June. The Delta climbs rapidly and the cloud was low so I quickly reached it and found it to be quite dense, I could skirt along the underside but felt the model would disappear if I entered it properly. Spotter Captain Slow said he could still see the model easily enough so there weren’t any concerns. I did the same on the second flight with no problems but it was really the wrong sort of cloud, a bit like driving in fog.By the time of the third flight the cloud had lifted and there were areas of blue sky so I didn’t think I’d be able to reach the clouds but a couple of minutes into the flight I decided to give it a go. I soon reached some gloriously fluffing bits of cloud and was able to fly above some small patches and see blue sky above me and bits of the ground below me, great stuff. I got tempted by a lovely looking cloud formation a little further on and headed for it. Captain Slow was dripping on about me being a long way off but what the heck, I could see perfectly!A few seconds later he said he’d lost sight of me so I throttled back and came down out of the cloud. I still had a perfect view on the goggles but there was one tiny problem, I hadn’t got a clue where I was! I circled aimlessly, looking for something I recognised, aware that the timer was now telling me I had two minutes of battery left. I spotted some unrecognisable buildings and knew they weren’t anywhere near where I should be so I headed away from them. Now Captain Slow was telling me to climb in the hope that he might be able to see me but to add to my problems I could see the motor was stopping now and again, presumably the radio going into failsafe. The picture on the goggles was still good but I was getting yellow and red signal indicators instead of green so I knew I was at the limit of the FPV range. When I saw two red indicators I turned to try to get a better signal while desperately searching for a landmark. I tried to take notice of what I could see, the rounded end of a valley, a couple of circles in cut crop, a telegraph pole, a field boundary, and suddenly nothing! The inevitable happened, I saw the motor stop and the goggles lost signal as the plane was very low and heading steeply towards the deck. It’s all in the video…There were only three of us flying that morning, me, Captain Slow, and Geoff Berry. After a quick recap of where the model was last seen we headed up to the masts where the gliders fly, it seemed the most likely area to search. We spread out in different directions, I was looking for the landmarks I’d seen from the air and headed off north along the South Downs Way. Things started to get familiar, there was the rounded end of a valley, cut crop, a line of telegraph poles, a field boundary…and an undamaged Delta sat of top of the crop, phew!Looking at Google Maps later it shows the model land 1.16km from the patch, nothing wrong with the range then.The map is looking due north, the masts are over towards the right. Lesson learnt, listen to the spotter and don’t get carried away by a perfect picture on the goggles. Captain Slow says I should be renamed Colin CloudPlane.

Patch News – May 2019

First, as Capt. Edmund Blackadder once said, “We’re in the stickiest situation since Sticky the stick insect got stuck on a sticky bun”. Dougal Entendre sent me that quote to celebrate the emergence this month of the latest club model, the Sticky. More on that later, the month of May saw lots of other exciting things as well.

The month began with the resurgence of the Colin Cowplain Flyer Fitness Club. After letting the members relax for a month or so I did some more parachute drops from the Bush Mule. I never expect anyone to do the retrieving and everybody moans about it but they still go running off after the wayward chutes! One rather blustery day the wind was obviously going in totally different directions at different heights and on one drop all the chutes ended up in the valley and the next time they went way down over the lower field. That time Dougal went off in hot pursuit not realising just how far they would go. He returned, ages later, puffing, panting and moaning, and that evening sent me a Google Maps screenshot with the parachute tracking marked showing a distance of 650m from the patch.It didn’t sound too bad to me but I suppose there and back was 1.3km and it was uphill most of the way back. Anyway he failed, he only found five chutes, the sixth was last seen heading in the general directions of Chichester at a great height, much higher than when I dropped it! The things I do just to keep the members fit and healthy…

On 12th May the field was being used as a car park for the Sustainability Centre Green Fair so some of us visited the Mini Airshow that was being held at the Drone Zone base on Popham Airfield. It was called MA5 (Mini Airshow 5), and MA6 is already on the calendar for 9th May 2020. It’s billed as a drone racing event with some fixed wing aircraft as an aside but when we went the aircraft side seemed to be bigger than the drone racing.The drone racing was interesting for a while but didn’t really do much for me although the people were very friendly and keen to tell us all about it. The aircraft side of things was really good with a fair cross-section of models from Wot-4s through to enormous turbines. Some of the display flying was excellent, I always find the turbines impressive and there were also several large WW1 aircraft that were nicely built and flown well. Several large 3D machines powered by petrol engines were very ably flown, some with smoke systems. About the only thing lacking were the trade stands, there was just one and that was all drone based bits and pieces although Dougal did manage to pick up a couple of speed controllers and some small props at good prices.

It was good to see Chas Butler return to the fold and fly regularly throughout the month. Chas must be one of the longest serving club members but had been absent from the flying field for a few years until this month. Chas is an excellent flyer with a B certificate and he gave sterling service as the club Secretary for twenty one years before deciding he’d done his bit and taking a step back. He’s returned flying a Radian electric glider and an electric Wot-4 and using a JR PCM9 transmitter with a 2.4GHz module. Later in the month he showed up sporting an extremely snazzy green transmitter which I believe is a JR XG11, very upmarket! Good to see you back Chas, now just stop working and fly with the Midweekers!

Geoff Berry also flew with us again in May, this time with a Max Thrust Riot, a model that’s similar in many ways to a Wot-4. Geoff seemed to be enjoying it and was flying very well indeed, partly due no doubt to his lovely Multiplex Cockpit SX9 radio (same as mine!). I failed to get any photos of the Riot on the ground but I did take some video and Kryten took some lovely flying shots.

In the January Patch News I mentioned that for Christmas my daughter had bought me a couple of indoor skydiving ‘flights’ at iFly in Basingstoke. On their website it says “Turn Dad into a flying legend’, does she not know I already am one?! Anyway, in May I went and did my bit and thoroughly enjoyed it. Basically the set-up is a transparent vertical 14ft diameter wind tunnel with a mesh ‘floor’ to stop you falling to the bottom if the fans stop. The average height that you ‘fly’ at is about 6ft above the mesh but you can go up to a max 39ft. An instructor is in the tunnel the whole flight to keep the student in the right place and stable. The air speed is controlled by an operator who is watching what’s happening the whole time and they adjust the speed from between 90mph and 180mph. The experience begins with a pre-flight briefing where you’re taught what to expect, what to do, and basic hand signals. Then it’s time to get kitted up, all the necessary gear is included in the price of the flights. On the first flight I got generally accustomed to the experience of floating around in a 120mph gale and was shown the correct position to hover mostly unaided. Before the second flight I was offered the chance of flying up to the top of the tunnel (securely held by the instructor) for an extra £7, how could I refuse?The controller raises the air speed when signalled by the instructor and up you go, weird! It was all over far too quickly but I really enjoyed the whole experience. I was surprised how busy the place was considering it was a Monday morning in school term time, it’s a very popular experience. Have a look at the website HERE

Catapult King never shies away from tricky projects and in May he turned up with an SR-71 Blackbird.This is what Richard says about it:

Following on from the influx of mid prop jets recently I thought I would do a Depron ‘quicky’ build of some sort and came up with the SR-71 with a pusher prop (needless to say it turned out not to be so quick). A colleague found a 3D-view print which I exploded until I got a fuselage that would be fat enough to hold a 3s-2200 lipo. The power train was going to be from my old HK AXN.

Having printed this off, I cut out a silhouette of the plane which even then was bigger than planned. There are two CF tubes running the length of the fuselage and a triangle of CF spars to support the wings. In addition this was skinned with 2mm balsa on the top. I thought there would be a weak point where the fuse meets the wing so I put a 4mm ply section in here as that’s also where the battery would go. I placed the electrics around until I found suitable places for each piece then started building with Depron. The fuselage first and getting the shape of the cockpit area was horrid, then equally difficult was getting the engine nacelles and cones roughly correct, this is what made the ‘quicky’ not so quick. The plane is covered with black and red packing tape with mylar tape on the underside to protect the Depron on landing. 

I wasn’t sure how the air from the elevators would react as it immediately goes through the prop so initially all four control surfaces were set up as elevons and as we saw on the maiden flight there was far too much throw and it did have to come down like an arrow didn’t it? I wasn’t going for the Concord droopy nose look. Subsequently the front has been rebuilt with ply all the way back to the wing area. The inner control surfaces are now elevators but the outer surfaces still have 50% elevator mixed in to support them and the throws have been drastically reduced and I now have a plane that is almost there. The power train is a 3cell 2200 lipo, a 30amp ESC, the motor is a 2200Kv something (from the AXN) and a 6×4 prop. It’s certainly fast enough I just need to get that trim right as I’m not sure it was designed to do a pirouette as seen in the video. Oh, and it is awfully difficult to spot the orientation so when things go slightly wrong they tend to go very wrong very quickly! 

Thanks for that Richard, it was a brave undertaking and you’ve done really well to get it flying so well.

While holidaying in the Lake District Basher Bob went to a Splash-In and took a few photos for us all to enjoy. Thanks Bob, it looks like a good event, shame there isn’t something similar locally as I’m sure several of us would like to give flying from water a try. I doubt we’d get away with it on the Heath for more than a few minutes.

During the recent HobbyKing price slashing of the foamboard jets Woody picked up an F-4 Phantom for £1.68! The Phantom is different to the other jets as it has a rear mounted motor and a box fuselage instead of a profile one. Personally I don’t think it looks much like a Phantom, at the very least the tail should have anhedral. I think Woody only bought it because it come in Blue Angels colours and of course Woody being Woody he’s added lights. As the motor is at the back the model required a fair bit of nose weight, more being added after the first attempt at flight. I was the nominated test pilot and had just about got it somewhere near in trim when it suddenly just stopped flying and crashed, fortunately with very little damage. With some additional nose weight the second flight went much better although the wings appeared to be twisting in flight, on a low fly-by we could see and hear a slight fluttering, not good. After a couple of minutes I was downwind heading towards us when the model just suddenly dived into the deck, this time with major damage. I think I probably went to full throttle as I turned into wind and the wings suddenly twisted making the model uncontrollable. You can enjoy the crash for yourselves in the video!

Meanwhile the fun continues with the other jets, Woody had the motor come loose on his Sukhoi, very loose!And Basher Bob did an ‘alternative landing’ with his Sukhoi, don’t worry Bob, it’ll buff out ok!

As I mentioned last month Captain Slow has now bought some FPV equipment. He’s fitted the gear into his Multiplex Twinstar, an ideal plane for getting used to flying FPV. His initial set-up was a bit of a compromise with the FPV transmitter being stuffed back between the servos due to the short antenna. He’s since bought an antenna extension and has managed to fit the gear in a much better way. At the time of writing Captain Slow has only had a couple of FPV flights with the Twinstar and he’s discovered it’s not especially easy to fly FPV but it’s very easy to get a long way away rather quickly! With a little guidance from the spotter all was well and he landed safely back on the patch. More to follow…

Time to get all Sticky now. Sadly the Sticky didn’t prove as popular as previous club models and only five appeared for the judging at the May club meeting.Dougal produced one that used the old wing from his now defunct Spad which meant it lacked dihedral but gained ailerons. So it’s Stickyish really and that earned him the Most Original Design prize.Unsurprisingly Woody’s creation was finished in Blue Angels colours. He won the prize for Least Likely to Fly as both wings had a huge amount of washout. Later Basher Bob took the wings home to straighten them as best he could.The prize for the Best Looking Model went to Percy Vears for his Baron Von Stickthofen finished model, nice one.The other builders were John Warren, who finished his in the now familiar red and white Warren Inc. colour scheme, and Basher Bob who had built a scaled up version, Extremely Sticky maybe?

John couldn’t make the flying on the Sunday, he gave some pathetic excuse about sunning himself on the other side of the world! Dougal’s flew very well right from the start, the aileron wing definitely proved to be an advantage. Having had the wings straightened somewhat by Bob Woody’s Sticky flew reasonably well, it looks pretty good on the video but Dougal says it was a tricky Sticky. I’ve since had a go with it myself and I’m not sure what has changed but it didn’t fly well at all, maybe the wings have warped again. After a few adjustments I got it flying fairly well but then the motor came off mid-flight. Fortunately it landed on the patch with almost no damage. Percy Vears’ Sticky flew well on the second flight after the centre of gravity had been moved forward, and Basher’s larger version flew very well straight from the start and needed no trim adjustments at all, well done Bob. This month’s video will show you how they flew on the day, Dougal’s was definitely the best flier. No doubt John’s will be flown next month so I’ll let you know how it goes.

Gentleman Jim brought along a Wot-4 Foam-E Mk 2 + in May. I’ve lost track of all the different versions of Wot-4s that have been produced but this is what the advertising blurb says about this one:

The ever popular Chris Foss Wot4 Foam-E Mk2 has been updated into the MK2+. The previous Wot4 Foam-E gained a reputation as one of the best sports models available and the Mk2+ builds on that with numerous new features. The model comes supplied with a powerful pre-installed brushless outrunner motor, matching 40A brushless electronic speed controller and 4 x 9g micro servos. All you need to add is your preferred receiver/transmitter combo and a 3S 2200mAh Li-Po of your choice.

Like the previous version, the Mk2+ only requires minor assembly to get airborne. No glue is required, only a cross headed screwdriver, a 10mm spanner and some double sided tape to mount your receiver.

Buried inside the structure there are numerous changes to the internal design. The tailplane has been re-designed for improved styling with solid tips and inset elevators for improved style yet still providing good control authority.

The wing has an extra carbon wing spar and the fuselage has extra carbon bracing making the airframe even tougher. The tail wheel has also been re-designed to be bolted on, allowing easy removal if accidentally broken. The control surfaces use ‘live’ moulded foam hinges with plastic hinge re-enforcement for extra security and peace of mind. Just like the previous version the control surfaces have carbon fibre re-enforcement for optimal control authority.

Well it all sounds good but unfortunately Jim’s came with a twisted fuselage which meant the tailplane was badly out of line with the wings. Jim added some packing under one side of the tail to bring everything back in line and it’s fine now but Jim was less than impressed with the quality of the model in general. Anyway, it’s all ended up looking good, rather like every other Wot-4 really! Jim asked me to do the test flight and after a few clicks of trim it flew beautifully, one of the nicest models to fly that I can think of actually. I’d love to know how many Wot-4s have been produced over the years, I would imagine it’s now in the hundreds of thousands, so the basic design has to be good. I think Jim will enjoy this one for a long time.

Kryten took lots of excellent flying photos this month including the above Sticky ones. Here are some of his others:

Patch News – April 2019

What a great month April was, not many April showers, an amazing Easter weekend, and loads of flying. The bullocks that joined us in March soon got used to us again and ignored us most of the time but did occasionally wander over and became annoyingly inquisitive. They seemed to have quickly learnt not to touch the fence, even if it was laid down, but they sometimes came right up to the pits area and had to be herded away before they chewed a model or two. I think they just want to be friends and have very little idea of the needs of model fliers! Matt snapped this photo of Captain Slow’s idea of herding them away… It makes me think of John Le Mesurier in Dad’s Army “I say, would you mind awfully popping down to the gate, there’s a good chap”.Can you think of a decent caption for the photo? Answers in the Comments section please, there will be a small prize for the one I like the most. Happily they moved out again at the end of the month so the field will hopefully be bullock free for a few weeks. The patch is in excellent condition and has been mown regularly by the Farts (Friday Afternoon Rural Trimming Society). One Friday afternoon Matt made an appearance and was cajoled into pushing the mower for a few minutes. Such a rare and momentous occasion seemed an unmissable photo opportunity!New member Iven has flown with the Midweekers on many occasions and has been practising hard for his ‘A’ cert.Before taking his certificate he was already on the lookout for a follow-on model that will test his skills a little more than his E-Flite Apprentice. He was very taken with Basher Bob’s Durafly Slow Poke and before you could say ‘PayPal’ one was on its way to him. Iven soon had it assembled and at the patch ready for flight.I test flew Basher’s Slow Poke for him and remember saying “If you can’t land this you can’t land anything”, it was a delight to fly, but Basher has never seemed totally at ease with it, maybe he’s changed some settings since that first flight.  He did raise a few eyebrows one day when he announced that he’d had a slow poke in the back of his car…When Iven asked me to maiden his new Slow Poke I was interested to see if it flew as well as I remembered Basher’s had. It did, the model needed no trimming and flew beautifully. Iven had a go with it and coped with no problems at all, I think he’ll enjoy it a lot. The 1200mm wingspan Slow Poke is made of EPO foam and comes as a ‘plug and play’ model, just add your own receiver and battery and off you go. I see that Iven is using one of the new Spektrum receivers that doesn’t have any external aerials. It worked perfectly and not having any aerials to route or worry about damaging must be a plus point. Finally, something I like about Spektrum!The motor is a 3648 700Kv outrunner that swings a 12×8 prop. It has a 40A Aerostar esc and uses a 3 cell 2200mAh lipo. Basher has been flying his on a 4 cell lipo but I really don’t think it needs 4 cells. Having proved the Slow Poke Iven returned to his Apprentice and passed his BMFA ‘A’ cert a couple of weeks later, well done Iven.You may have noticed that Bob has reverted back to Basher having been Bob the Builder for some while now. Bob first became Basher following his involvement in a series of mid-air collisions, none of which were necessarily his fault, but he always seemed to be there. But then things changed, the mid-airs stopped and we rechristened him Bob the Builder…until now. Yes, he’s been at it again! One fine April day I was flying my FPV Sukhoi and both Woody and Basher decided to fly their foamboard jets to give me something to follow. Woody was flying his Sukhoi nice and steadily when Basher’s Mig made a sudden turn and cut right across him, resulting in the a series of prop hacks to the leading edge of his left wing. Both models landed safely and Basher’s was completely unmarked, typical!Both the models were out of sight of my FPV camera at the time so I didn’t see any of the action but Iven happened to be videoing from the ground and caught the action. I’ve included the footage at the end of this month’s video so you can all enjoy it! Strangely, although Woody was the victim of the collision for some reason the incident seemed to upset 1066 much more than Woody and he really laid into poor old Basher.Violence towards OAPs is not something to be encouraged, especially as I’m one of them!

One Sunday morning saw lots of full-size activity around the field. As well as the often seen paragliders up by the masts a few high-tech hang gliders were flying and some overflew the patch at great height. Then, just as we were packing up to leave, four full-size gliders started circling in a thermal right above us. It was a lovely site and as we strained our necks to watch Basher laid on the ground for an easier view… the real reason for the photo above.The gliders were very high and I didn’t manage to get all four in a photo but you can just about see two and a half here. This month’s video includes a snippet of three of the gliders circling upwards in the thermal.

Basher also had a go at taking out my Sukhoi with his own Sukhoi on one of my FPV flights, it’s in the video…Dougal and I continued with our FPV learning and we’ve progressed with our flying. Dougal did the first low level pass through the Harper’s Oak group of trees one Friday afternoon when I wasn’t present so I was forced to copy it the following Sunday morning! We also both made some more FPV purchases. Dougal had been using some cheap Crazepony box goggles that performed reasonably well but they weren’t as clear as the not quite so cheap Cyclops box goggles that I have, so when he spotted some second-hand Aomway goggles for sale Dougal snapped them up.The Aomways are not box goggles so are smaller and lighter to wear and have a much better resolution but even second-hand cost four times as much as the Crazepony ones. And they still look almost as stupid!Not sure who that bald bloke is! My Cyclops goggles are big and cumbersome but have a good picture quality and the only complaint I have with them is the low quality recordings of the built-in DVR (video recorder). Dougal spotted an FPV transmitter that has a built-in DVR on the Banggood website for around £15 so I ordered one to try. As the recorder is on the tx rather than the rx in the goggles there is no signal break-up that might occur on the downlink and the video quality is much better than the one built into the goggles.The recorders save the videos to micro SD cards, either in the goggles or on the tx depending on which type you are using. Dougal then realised that his video quality wasn’t as good as mine and that could only be down to his cheap camera. I’m using a Foxeer Predator Mini V2 camera that cost about £32 from HobbyKing but Dougal was using a very cheap camera he bought some while ago. So he’s now bought a Foxeer Monster Mini Pro V3 from HobbyKing that cost around £18 and has similar specs to mine but with slightly fewer features. He’s mounted it on his Tomahawk flying wing on a small servo so he can look from side to side using the rudder control.Its early days but the video quality is definitely much better than with his previous camera and the swivel mount is also looking worthwhile. Captain Slow is also now getting into FPV and has ordered the same goggles and tx as me and the V3 version of the Foxeer Predator Mini camera. He’s not certain which plane he’ll fit the gear to yet but his Multiplex Twinstar is looking like an obvious choice.

Gentleman Jim hasn’t managed to get to the field much recently but he did bring along a very pretty little Freewing Space Walker to fly a couple of times in April. Jim bought it on a whim while browsing in Modellbau UK at Medstead.Its 1120mm span and weighs just 850g so probably not a model for a windy day but it does fly very nicely. The EPO model comes complete with four 9g servos, a 3130 1200kV motor, a 30A esc, and a 10×6 propeller. It requires a 3 cell lipo in the 1600- 2200mAh range and a receiver of your choice but is otherwise complete. It was a bit blustery on the day of its first flight so the Space Walker got chucked around a bit but it flew well anyway. The weather was much calmer for its second outing and it was much more pleasant to fly, I think Jim will enjoy this one.

Ok, now for some amazing news, you’d better be sitting down for this one: Captain Slow has finished his Zagi!It only took him five months to complete the ‘buy today, fly tomorrow’ model, incredible! After much deliberation about the choice of motor and how to hold the Zagi to launch it Captain Slow settled on a Pelikan 2200kV inrunner motor and fitted a small balsa block as a launching hold under the nose. As the original was designed for a small brushed ‘can’ motor and relatively heavy nicad battery Captain Slow found that the brushless inrunner motor at the back and much lighter lipo battery at the front meant a lot of lead was required to achieve the correct centre of gravity. You can see some of the weights along the leading edge in the photo.But although the Zagi felt very heavy it flew extremely well and the extra weight didn’t seem to bother it at all. Captain Slow wanted it as a windy weather model anyway so the extra weight is probably not a bad thing.After only a couple of flights the motor started making an odd noise and when he landed it Captain Slow’s finger discovered that the motor was hot, sizzlingly hot in fact! The rear bearing had come loose and the motor was totally ruined. I remembered I had a similar size inrunner at home so donated it to the worthy cause and, although the 3900kV is really much too high (it’s really an EDF motor) it fitted ok and with a 4.5×4.1 prop it does the job perfectly. The Pelikan motor was using a 6×4 prop but that pulled more than 60A with the new motor. The Zagi flies much better than expected, it’s aerobatic and despite the weight it glides very well. It was almost worth the wait…

Following on from his TSR2 success last month Dwayne Pipe has continued to make a few changes and improvements to the model and it is now flying very well indeed. It still needs a good heave when launched but it goes away well now and it both looks and sounds great in the air.I believe Dwayne will be telling us all about the model at the next Official meeting on 16th May.

Kryten was good enough to send me a few more excellent quality photos this month, including the one above.

Video time now which this month includes contributions from Dougal and Captain Slow:Please watch the video full screen, it’s so much better with small models flying around. If the video won’t play for you click HERE

Before I went to the airfield today I said to the wife “I am just going to polish the wings and clean the screen”
“You’re going flying, aren’t you”  she moaned. “No I am just going to clean the plane” I promised.

I got to the airfield and did my cleaning jobs on the aircraft. On the way home driving through the village I came across a pretty young woman in distress with a punctured wheel on her bicycle.

“Can I help you” I asked. “Please could you give me a lift to my hotel at the end of the village?”
I placed her bicycle in my boot and drove to the hotel. She was very grateful and invited me in for a coffee. One thing led to another and a jolly good time was had.

I drove home and was greeted by the wife saying “What time do you call this, you’ve been flying haven’t you”
“No, I went to the airfield, and cleaned the aircraft. On the way home I met a woman in distress took her back to her hotel and made mad passionate love to her.”

“You’re such a swine” she said “You promised me you wouldn’t go flying.”

Patch News – March 2019

After the unseasonable February weather normal service was resumed in March. Overall it wasn’t bad although there was one week of continual high winds and torrential rain which just happened to be the week I was in Marrakech! Farmer George put the bullocks in the field mid-month and, being a new young herd, they were very inquisitive and frisky. Some of us were in the field flying when the bullocks arrived and we only just managed to get the fence up round the patch before they reached us. There was lots of laughter as they discovered what an electric fence does! The fence is working well and, unlike the surrounding area, the patch is still in pristine condition. The Farts have cut the grass several times in March and it really is as good as it’s ever been at the moment.

At the end of February Norwegian Nick flew his Kavan Bird of Prey, it’s previous outing being back in January 2016. The Bird of Prey is a long discontinued kit that has a fibreglass fuselage and obechi veneered foam wings. The wingspan is approximately 58” and the all up weight is around 2lb 14ozs. Back in 2016 Nick was running a different fan/motor/battery set-up and although the model flew ok it seemed to make a lot of noise but lacked power. So now Nick has fitted a Mega 16 EDF motor, a YEP 60A esc and is using a 4 cell lipo instead of the original 3 cell.He also made and fitted a thrust tube out of glass fibre cloth to make the whole thing more efficient.It certainly worked as the model now has much more power and is significantly quieter. It flies really well and I expect we’ll see a lot of it through the summer months. You can see it flying in this month’s video.

On the 3rd of the month those of us who are on WhatsApp were alerted by Bob the Builder to a massive price reduction of the HobbyKing foamboard models. Various ones were in the sale including the popular Sukhoi SU-27 and Mig-29 and the prices were ridiculous, the SU-27s were slashed to £1.68 and the others were in a similar range.Bob ordered himself a couple of SU-27s, Woody went for an F-4 Phantom, and I jumped in quick with an order for six SU-27s, one for me and five for raffle prizes. Once postage was factored in those six cost just £2.50 each, ridiculous! Great spot Bob, thank you, and it shows the worth of being on the club WhatsApp list.

I’m looking forward to seeing how Woody’s Phantom flies, it’s a little different to the SU-27s and Mig-29s in that it has a box fuselage and a pusher motor right at the back rather than the mid mounted engine of the others. Personally I prefer the look on the similar T-45, I’ll wait and see how the F-4 turns out and then I might be tempted.

Bob the builder wasted no time in putting one of his SU-27s together and brought it along to fly one midweek day.

But he noticed a problem, luckily before flying, and had to take it home again to repair. Can you spot the problem?A couple of days later he was back and the Sukhoi flew perfectly with little trimming or adjustments required. Bob is using a 2826 2200kV motor with a 7″ prop and has opened up the prop slot as usual and it works a treat, not too noisy at all. I’ve lost count of how many foamboard fighters there are now, at least sixteen and more on the way.

During February I played around dropping parachutists from my Bush Mule and was generally pretty pleased with the results, although I did have to make several trips to the bottom of the valley! Several times I dropped multiple parachutists but they were really a bit too big for the cargo bay and sometimes got jammed in the door. So this month I scoured the internet for smaller parachutists and discovered some that were not only about half the size but also incorporated smoke bombs. As they were smaller I figured they wouldn’t drift so far despite having to be dropped higher to allow the smoke bombs to discharge. They came in packs of eight and were about £24 including postage from China so I bought one pack to play with. I tested them on a rather murky day when Kryten was on hand with his camera and they worked fairly well although not all the smoke bombs worked properly and they all landed in the bottom field! Considering the height I dropped them from Kryten did well to snap a reasonable photo.The smoke bombs are replaceable items but spares can only be purchased in packs of twenty four so it would be rather expensive to do very often but meantime I can use the parachutists without the smoke. Maybe I’ll order some more smoke bombs and save them for special occasions.

Last month I featured Dougal Entendre’s new Tomahawk flying wing that is kitted out with FPV (First Person View) equipment. After the initial flights he fitted a pair of larger, ex-Wingnetic, fins to aid stability and got on pretty well with the FPV flying. But he was getting lots of signal break-up so ordered a few different pieces of equipment.I was fascinated by the FPV and ordered some gear for myself, leaning heavily on Dougal for advice. It’s quite a steep learning curve as neither of us really know much about it but in March we both managed several successful flights and began to feel reasonably at ease while flying. So what do you need? A basic set-up consists of a small camera to mount on the model, a transmitter (with an antenna) that sends the images back to a pair of goggles that are fitted with a receiver, and a video recorder (DVR) if you want to record what you see in the goggles. We both have diversity goggles which means the receiver has two antennae and uses whichever one is receiving the strongest signal at the time. Dougal’s goggles have a built-in battery but mine use a separate three cell lipo. Comparing the goggles mine seem to have a slightly better screen image but Dougal’s have a better DVR. We are still very much at the learning and experimenting stage and the antennae seem to have quite a large effect on the performance. Both our systems work on 5.8GHz, so avoiding any interference with our 2.4GHz RC sets, various other frequencies can be used but 5.8 is the most common. Watching Dougal’s 26” span flying wing made me think I needed something rather larger and slower to start with. Obviously you don’t want something that has a propeller in front of the camera and I eventually decided to fit the gear to my foamboard Sukhoi SU-27. As it’s a very cheap foamboard plane it doesn’t matter too much if I break it, it has a centrally mounted motor so the propeller isn’t a problem, and it will fly slowly when required. It’s not the perfect model, something like a Bixler would be better but I don’t have one. My Bush Mule twin would be perfect but I don’t want to risk crashing it while I’m learning. As I’m able to fly midweek I’ve been able to get more FPV flights in than Dougal and I think the Sukhoi is probably easier to fly. I’ve found the temptation is to fly at slow speed and unintentionally pull in up elevator at which point the plane simply stops moving forward so now I force myself to fly faster and lower. It is essential (legally and sensibly) to have a spotter alongside the pilot and stay in line of sight view so they can take control if there’s a problem with the FPV. Now we are getting more used to flying FPV we find it tempting to fly further away than we should (we can see perfectly well where we are) which causes shouts of “Turn NOW” etc. from the helper, (in my case mostly Captain Slow) very amusing!. There is some footage from both models in this month’s video.

If you fancy having a go at FPV a HobbyKing Bixler is the perfect model to begin with and Stanley Knife has one.It’s a simple but efficient electric glider style model with a high mounted pusher prop so ideal for FPV. Stanley’s is a Bixler 2 but HobbyKing still sell the original Bixler 1 and also the latest version, the Bixler 3. They’ve grown in size with each version, the Bixler 1 being 1400mm span, the 2 is 1500mm spam, and the 3 is 1550 span. Version 3 comes with an undercarriage but an aftermarket undercarriage is available for versions 1 & 2 if you want one. It’s become Stanley’s model of choice when he wants to fly something gentle and I can see why, it flies extremely well.

A little while ago Dwayne Pipe announced his intention to build a TSR2. He knew I’d built an electric powered pusher version many years ago and picked my brains about it. I built mine in 1992 from a Jeremy Collins plan that was featured in RCM&E and it was designed for an IC engine, ‘minimum power OS25FSR’ was stated. I made lots of changes to make mine lighter but kept the outline the same as the plan. Originally it flew on a 7 cell NiCad pack but the power was marginal so I altered it to take 10 cells and then it flew well.In those days it simply wasn’t possible to have a ducted fan version but times have changed and that’s what Dwayne intended to try. He planned to use a HobbyKing 70mm 5 bladed ducted fan sold as a spare for their Durafly Vampire with a 3300Kv motor so he scaled down the fuselage a little to suit the fan housing and save weight but kept the original 30” wingspan. Mine had an all moving tailplane as per the full-size but the mechanism would have been in the way of the fan so Dwayne’s has a fixed tailplane with elevators. The TSR2 has very small intakes that are made even smaller by inlet cones so Dwayne has added a series of cheater holes in the fuselage sides under the wing. The fuselage has plenty of room for a 4 cell lipo of either 2200mAh or 3300mAh capacity and he’s using a 60A speed controller. At full throttle the motor pulls 49A and the fan gives 2lb 6oz of thrust which is the same as the weight of the model with a 2200mAh battery.So does it fly? Yes, and it’s surprisingly similar to mine all those years ago. It takes a good heave to get away from the launch but once it’s away it goes well. It rolls well and even inverted flight is ok but it won’t loop. Well it might after a 500ft dive but not from level flight, it gets to vertical and just stops, exactly like mine used to. But it’s superb at fast low passes and really looks the part during those. Dwayne is going to enlarge the cheater holes to try to get a bit more thrust and also has some covers for them so they don’t look like airliner windows! He’s also increasing the size of the elevators and will try moving the centre of gravity back a little. But even before the mods it’s a great success and you can see parts of the first three flights in this month’s video. UPDATE: On 28th March, having carried out the mods I mentioned above, Dwayne had a further two flights with the TSR2. It went away from launch much better both times, had a bit more power and it will now loop. Superb!

Dougal Entendre got tempted by a little F3A (pattern ship) called Skylark on the Banggood website. Banggood describe it as a trainer so Dougal should just about be able to cope with it! I assume they mean an aerobatic trainer as it’s most definitely not a model for beginners. It’s available in blue, green, or red colour schemes and Dougal plumped for a blue one. The model is a 950mm span EPO foamie and comes as airframe only, all the electrics have to be provided by the builder. Dougal doesn’t rate Banggood packaging as the box was quite badly knocked about when it arrived and one end was completely open, presumably where it had been inspected by customs. The model inside was a bit bashed cosmetically but basically sound so Dougal put in a lot of effort to get his son Cameron to assemble it for him…lazy bugger! The instructions call for a 2216 motor, 40A esc and a 9×6 prop. This is all powered by a 2200mAh 3 cell lipo that also powers the receiver and 4 x 9g servos.It’s a pretty little model and certainly looks as if it should fly well. But the initial take-off proved ‘interesting’, the Skylark was way out of trim and it took a couple of minutes for Dougal to tame it. But once trimmed it seemed reasonable and, having done a bit of sorting later at home, the next time out it flew very nicely. I think it will prove to be a good all round model well suited to our field. The hairy first flight is in the video.

You may remember that at the end of December Matt Takhar’s Velox misbehaved itself (nothing to do with the pilot obviously…) and required a new fuselage. At 81” wingspan the Velox is a large impressive model that’s powered by an Xpwr 40 (40cc equivalent) motor running on 12 cells and has a Castle Phoenix Edge HV120 speed controller. The gear was all transferred into a new fuselage by ProBuild who put the first one together and Matt did a bit of tarting up with some new stickers. So in March the model was brought out once again and the first flight went perfectly. It has an impressive amount of power and really eats up the sky which makes it difficult to video but I got some of it. But during the second flight there was a bang and I thought the motor had kicked the prop loose. Matt called dead-stick and headed for the patch but on the approach we saw a sudden ball of flame followed by a plume of smoke! Matt did very well to make a perfect landing on the patch and Nick rushed over to disconnect the battery.Fortunately there was no fire and the ball of flame turned out to be the speed controller exploding! The model survived unscathed apart from some minor burn marks inside where the controller was mounted. Probuild/Castle Creations have agreed to replace the esc as apparently it’s not supposed to do that!

Speaking of fires: “No, I’m sure it’ll be perfectly alright, nothing can possibly go wrong”:“OOPS!”Don’t worry, I don’t know what the pall of smoke was but it was nothing to do with Woody or any of us!

Nothing to do with Petersfield Aero Modellers or the patch but I spotted a video that I thought you’d like to see. It is Gernot Bruckmann flying an indoor model and winning his 4th World Championship in a row. I saw him flying outdoors for Multiplex at the Multiplex Airshow in Germany two years ago which is odd as he uses Jeti radio, maybe with Multiplex servos. I have to say he’s not bad! The video is worth watching if only for the take-off: 

 

Kryten has just sent me some superb flying photos that he took last month. In particular Page Boy’s Harvard and Bob the Builder’s Tiger Moth look fantastic.

Monthly video time now, this month it includes helpings from Iven, Dougal, and Captain Slow, thanks chaps:

Please watch the video full screen, it’s so much better with small models flying around. If the video won’t play for you click HERE

A chap was sitting at an airport bar when he noticed a beautiful woman sitting next to him. He thought to himself  “Wow, she’s so gorgeous she must be a flight attendant. But which airline does she work for?”

Hoping to pick her up, he leaned towards her and uttered the BA slogan: “To Fly. To Serve?” She gave him a blank, confused stare and he immediately thought to himself “Hmm, she doesn’t work for BA.”

A moment later, another slogan popped into his head. He leaned towards her again, “Something special in the air?” She gave him the same confused look. He mentally kicked himself, and scratched American Airlines off the list.

Next he tried the United Airlines slogan: “I would really love to fly your friendly skies?” This time the woman turned on him and screamed “What the *@#! do you want?”

The man smiled, then slumped back in his chair… “Ah yes, Ryanair”.

Patch News – February 2019

What a Fantastic February! The first Sunday of the month saw the field covered with a light dusting of snow whilst being bright and sunny with light winds, perfect for me to try the skis on my Bush Mule. The snow wasn’t very deep so wheeled models (and their pilots) coped with the conditions ok as well. A great day with a decent turnout. Later in the month we had a long spell of dry weather with light winds and a fair bit of sunshine. The last Sunday was absolutely glorious and we had thirteen flyers come out to play, I would think that’s a record for February. I played around with a couple of cameras on the Bush Mule throughout February and managed to capture some reasonable video of touch and go’s in the snow, general scenery, and also dropping parachutes later in the month. I also tried to get some air to air video with a camera on my SU-27 and had a very close encounter with Woody’s Mig-29! I’m afraid the quality of some of the screenshots from a cheap video camera is poor but you get the idea.

At the end of January, too late for the last Patch News, Matt Takhar flew his new 67” wingspan Pilot-RC Extra 330SC. It’s almost identical to Newbie Nick’s Extra that I featured last month but it’s a second generation model not a first. Matt has fitted a 470kV Potenza 60 motor with the HobbyWing speed controller and uses a 6 cell 5000mAh lipo battery. It swings a 20×8 wooden prop and, as you’ll see in this month video, has loads of power. The video is of the understandably cautious first flight and, like Nick, Matt is now getting more adventurous, flying lower, closer and more aggressively. The Extras are lightweight to the extreme, the structure really is only there to keep the various components apart and I would hate to see the result of even a heavy landing.

When we had the snow at the field many of us realised our lipos were suffering in the cold and not giving the power they do in warmer weather. I spotted a heated lipo bag on the HobbyKing website but it was out of stock. However, an alternative heater for R/C car tyres that doubles as a transmitter muff heater popped up on screen and figured I could warm my batteries in the muff and then keep my hands warm when flying for only around £13. It consists of an adjustable temperature controller connected to a pair of pads containing heater elements and the power is supplied by a 2 or 3 cell lipo. Having found the controller to be very sensitive I rewired the pads in series rather than parallel which made it more manageable. I fitted the system into my Turnigy muff with strips of Velcro so it’s easy to remove when not required. So, did it work? Yes perfectly, we haven’t had a single cold day since!

Yet more of the foamboard jets appeared in February, at the last count there were thirteen fourteen in the club.Gorgeous Gary, spurred on by the success of his Mig-29, has now built a Sukhoi SU-27. It’s one with the new colour scheme, quite bright rather than the original grey ones like mine but is otherwise an identical model. Gary has added a second carbon tube to stiffen up the tail end and he wasn’t keen on the unusual format of linked ailerons and elevators so has added a couple of extras servos and the surfaces are now all independent. When I put mine together I thought having them coupled the way HK suggest was very odd but it seems to work perfectly well. I haven’t flown Gary’s so I can’t say if it’s any better or not, it would be interesting to compare the two. As you’ll see in the video Gorgeous Gary enjoyed flying his Sukhoi in the snow, it certainly flies well and maybe the controls look more positive than mine. A little bird tells me he’s bought a second Mig to join his existing one…!

Shock horror, Captain Slow has also completed one of the new colour scheme Sukhoi SU-27s, a record two new models in two months! His is completely stock and just uses two servos to control the ailerons and elevators. All of these foamboard jets are using motors with a kV of around 2200 but Captain Slow had a 1400kV motor spare and decided to try it in his Sukhoi. The advantage of a lower kV motor is that it will swing a bigger diameter propeller and hopefully keep the noise down a bit. I think it’s fair to say that some of us doubted the lower kV motor would be any good but in fact the plane flies the same as all the others with the advantage that it’s a little quieter. At first he said he didn’t like it as much as the Mig-29 but has since got used to it and now loves it. They do fly surprisingly differently, both are good in their own way, the Mig is faster but the Sukhoi is better for high alpha stuff. I know the Mig is faster because Captain Slow decided to ram my Sukhoi from behind with his Mig! To be fair he’s probably never experienced anyone flying slower than him before. Dougal managed to capture the collision on video so you can watch it before deciding for yourself that it was Captain Slow’s fault. This is where they ended up.There was zero damage to my Sukhoi and just a small chunk out of the foamboard on Whacker Wheeley’s Mig where it hit my propeller. He’s replaced the chunk and added libellous markings!Despite his continual moaning about hating the foamboard jets 1066 has also succumbed to a new Sukhoi! He’s using the stock coupled aileron/elevator set up using just two servos. I’ve retro fitted one servo to move one rudder on mine but 1066 just had to go one better and he’s fitted two servos to operate two rudders. The rudders are quite effective, presumably two more so than one, and enable some very strange manoeuvres to be performed once you get used to them. After 1066 dripped on that his Sukhoi wasn’t nice to fly I took a look at it and decided his CG was about 6” too far back…well maybe not that much but it was certainly a long way rearward.Having checked out the locations of the radio gear and battery on all the other SU-27s he’s since repositioned everything to bring the CG forward to the correct place and now begrudgingly admits that he’s enjoying flying it!

Yet another foamboard jet, this time it’s an F-35 Lightning which was put together by Cream Egg. I was asked to do the test flight and quickly discovered that Cream Egg’s batteries were past their best, although fully charged they didn’t provide enough current to fly the F-35. We tried it with one of my packs and it flew fine after a few tweaks to the movements and trims. The only problem was that it was very noisy, the centre mounted motor makes all these foamboard jets noisy and the propeller slot needs to be enlarged to lower the noise.Cream Egg has cut the slot a little but the propeller tips are still close to the foamboard and that’s what causes the noise. No problem, a couple of minutes work cutting the foam well clear of the front of the propeller will sort it out.

There are some videos on YouTube of a chap who’s added an undercarriage made from plastic tie-wraps to his foamboard jets and Cream Egg has copied the idea. In the videos the guy is taking off from tarmac and the jets skid along on the plastic loops but I’m not sure they’ll work on grass. But nothing ventured nothing gained, we’ll see… In the photo of the underside you can also see how Cream Egg has mounted the servos. Er…the servos are supposed to go in the cut outs in the sides of the ‘fuselage’, or maybe I’m missing something? Newbie Nick also has an F-35 and it flies well so no doubt Cream Egg’s F-35 will soon be joining all the other hooligans careering around the sky.

Dougal Entendre has been hankering after an FPV (First Person View) model for a while. He had a go at it with his old Olympic glider a while back but he was using the rather small screen on his Devention transmitter rather than proper goggles to view the transmitted video stream. The system worked but he found the screen difficult to see, especially in bright sunlight, so he asked Mrs Christmas (Angie) for a pair of goggles. Sure enough a pair of Crazepony VR008 Pro FPV goggles with built-in digital video recorder turned up in his Christmas stocking. (I would normally make a comment at this point about stockings and Tranny Agate but he’s getting fed up with it so I won’t). He bought a Durafly Tomahawk from HobbyKing which is designed for FPV racing and fitted it out with the camera and transmitter from the Olympic. The first flights were on the snowy Sunday and Dougal flew the model in the normal manner (not using the FPV) and quickly discovered that the Tomahawk was a bit of a handful. Well it is advertised as a Mini Racing Wing so that wasn’t totally unexpected I suppose. Kryten was monitoring the FPV via the goggles and reported that it all worked well as long as the model didn’t get too far away. Dougal decided the Tomahawk needed more fin area so back in the workshop he fitted it with a couple of cut down fins from his now defunct Wingnetic. The photo shows the mock-up before the fins were cut down.Next time out it flew much more steadily and he decided to try flying it FPV with me as the obligatory ‘competent observer’. All went well, better than I expected actually, and Dougal had a couple of flights totally unaided other than a few comments from me if I felt he was getting a bit too far away, he even landed safely back on the patch.Having watched the onboard recording of the second flight I was surprised to see that the model was actually flying much closer to us than I’d thought but as it’s only 670mm (26”) wingspan it was bound to look small to me. You can see in the video that there’s some signal break-up which Dougal said didn’t happen on the first flight when the DVR wasn’t running so maybe the DVR is a source of interference. Dougal is planning a few changes to the set-up and then more flights will follow. I fancy having a go at FPV myself and have ordered some equipment…watch this space!

Not one to hang around 1066 hasn’t just built a foamboard SU-27, he’s also built a lovely little HK Mini Edge 540T.It’s one of their ‘EPP skins over a ply and carbon framework’ type of model that has now sadly been discontinued, 1066 has had the kit in his loft for a while. The Edge is 935mm (36.8”) wingspan and 1066 has fitted a 28mm 1400kV motor, a 10×4 prop, and a 50A speed controller. He uses a 3 cell 22mAh lipo which gives decent length flights. It flies brilliantly and in the video you’ll see it knife-edging from horizon to horizon.

Stanley Knife has put together this lovely looking ASW-28 that he won in a recent club big raffle. The 2540mm wingspan electric glider comes as a plug and fly model with all the electronics pre-installed. The motor is a 4018-850kV outrunner, the ESC is a 30A with BEC, and there are 6 x 9g servos controlling ailerons, rudder, elevator, and flaps. The fuselage is blow moulded plastic and the wings and tail are moulded in EPO foam.Stanley is using an 1800mAh 3 cell lipo but as you can see there’s loads of room for a bigger battery if required. The ASW flies beautifully, it’s certainly not overpowered but performs gentle scale-like aerobatics very nicely.

Now for something a bit special, Page Boy has treated himself to a Freewing Bae Hawk T1 in the Red Arrows colours. The 1020mm (40”) wingspan plug and play EPO foam model uses a 12 bladed 70mm diameter fan that’s spun by a brushless inrunner motor connected to an 80A speed controller and a 6 cell 4000mAh battery. That set-up provides a lot of thrust but has a very quiet turbine like sound. The Hawk is a very high quality model and looks fantastic with it’s lights, flaps, and retracts as standard and Page Boy’s came with the upgraded sprung undercarriage oleo set.Page Boy asked me to do the maiden flight as he’s never flown a ducted fan model before. The Hawk took-off from the patch nicely with half flap (the grass is in great condition at the moment) and required little trim to fly straight and level. With the wheels retracted she’s quite fast flat out but she’ll also fly slowly when throttled back and I didn’t find any handling problems. Page Boy had a quick go on the first flight before handing the transmitter back to me for the landing and she came in beautifully with full flap and landed gently on the patch. He had longer on the controls on the second flight and seemed to be getting the feel of ducted fan flying. I love it…want one…!

This month’s February Funny was sent in by Bob the Builder:

Yesterday my daughter emailed me, asking why I didn’t do something useful with my time. She said she was ‘only thinking of me’ and suggested I go down to the Pensioner Centre and hang out with other chaps my age.
So later I replied to her email saying that I’d been and had joined the Seniors Parachute Club.
She wrote back, ‘Are you mad? You’re much too old now, you can’t start jumping out of aeroplanes!’
Sensing that she didn’t believe me, I told her that I even had a Membership Card and emailed a copy to her.
Immediately, she rang me and yelled, “Good grief, Dad, where are your glasses? This is a membership to a Prostitute Club, not a Parachute Club!” 
“Oh dear, ” I said, “I signed up for five jumps a week!”
The line went dead…

Patch News – January 2019

The club has had a busy start to the year with lots of flying at the patch and several new models being flown.Obviously January brings some challenging weather but overall it hasn’t been too bad, mostly fairly mild although some days were very cold, especially if the low temperatures were combined with strong winds. As I write this on the last Sunday morning of the month I’m not flying because the Hampshire Astronomical Group live weather station (which you can see by clicking HERE) is showing a 10 minute average wind speed of 29mph and a high of 47mph!But we’re a hardy lot (well some of us are anyway) and we’ve managed to fly regularly.

As we were returning to the cars after one flying session I noticed a very unusual weather feature, a bank of cloud with an almost dead straight edge that ran from horizon to horizon. I think 1066 said it’s called a Step cloud.The photo doesn’t really do it justice but you can get the idea, it was certainly very dramatic.

We were pleased to welcome a new member, Ian, to the club in January. Ian’s surname is Venn and for obvious reasons he was immediately given the nickname Iven, so if you’re wondering why it’s not spelt Ivan, that’s your answer. Iven visited the field, asked lots of questions about what to buy and from where, and then went to SMC and bought an E-Flite Apprentice fitted with Spektrum radio…hmm. But the Apprentice is a great trainer and it comes with SAFE Technology (Sensor Assisted Flight Envelope) which in theory makes it almost impossible to crash.The package includes a 5 channel Spektrum DXe transmitter but that’s a very basic transmitter so Iven also bought a Spektrum DX6e for a bit of future proofing and bound that to the Apprentice instead of using the DXe.There is some setting up to do on the transmitter to get the SAFE Tech working correctly but Iven thought he’d sorted it ok when he brought it along to test fly. I gave the 1.5M span Apprentice a quick check over, discussed the various SAFE modes, switched to Expert mode, and all seemed fine so I took it up. Almost immediately it was clear that the SAFE Tech was not performing as it should and was fighting against me as I tried to fly a circuit. I didn’t feel as if I was in total control so I landed. You can see that brief flight in this month’s video. We played around with the different modes and tried again a couple of times but it just wasn’t working correctly so Dougal Entendre and Captain Slow gave Iven a go on their Hummers, hardly ideal trainers! I contacted Kryten as he had learnt to fly with exactly the same model and radio gear and he confirmed that getting the DX6e to work with the SAFE Tech was a bit of a struggle but sent me some web links and YouTube videos to look at. I passed the info on to Iven who had another go at it and returned to the field the next week confident that it was now correct. I flew it again in Expert mode but with much the same results so I switched to Beginner mode and then it seemed to be working better.At last Iven was able to have a go at flying and he managed a couple of circuits before it became clear the SAFE Tech still wasn’t right so I landed the Apprentice again. By now I was being to think it was me so I got Dougal to fly it but he also quickly found the SAFE Tech wasn’t right and landed. I believe Iven is now going to remove the SAFE receiver and use the ‘normal’ one that came with the DX6e transmitter so we can just teach him in the usual manner. It’s a great shame as Kryten’s set up worked perfectly from day one and he learned to fly very quickly with very little assistance from others. In the meantime Dougal has set Iven up with a flight simulator so in a couple of weeks he won’t need any help at all anyway…possibly…

If you read Patch News last month you’ll know I was fortunate enough to receive an Avios Bush Mule for Christmas. Once Christmas and New Year were out of the way I moved my models out of my storeroom and it became a model room once more so I was able to assemble the Bush Mule. There really is very little involved in putting it together, just a case of joining and bolting on the wings and wing struts, fitting the undercarriage, and bolting on the tailplane/fin assembly. I also epoxied the tailplane/fin assembly in place, the bolts didn’t seem too firm to me. So far so good, but it took me quite a while to connect it all up and program the radio. Both speed controllers and motors come ready fitted and wired up but they each require a radio channel of their own and I wanted to mix them with rudder to give differential thrust when using the rudder. There are also flaps which I programmed using flight phases so I have Phase 1: Flaps up for normal flight Phase 2: Half flap for take-off, Phase 3: Full flap for landing.Add to this the cargo door, steerable nose wheel, and lights as well as two aileron channels and elevator and there’s quite a lot of wiring and setting up to sort out. The speed controllers are also able to switch the motors into reverse, useful if you fit the floats and fly from water, but I didn’t have any spare channels left so I can’t use reverse thrust. I am also using telemetry, so I fitted a Multiplex 150A current sensor which displays live current draw, max current draw, receiver voltage, the lipo voltage, the strength of the signal that the transmitter is getting back from the receiver, and, most importantly, the milliamp hours remaining in the lipo. All the values can be displayed on the transmitter screen and spoken as well but of course that’s far too much information to take in during the flight so I just have mine set to speak the milliamp hours left when I flick a switch. So it’s like a fuel gauge i.e. it will say “One thousand three hundred and eighty one milliamp hours”. It also speaks the throttle open time when I switch it.The first flight was fine, almost no trimming required, and the only problem I found was that the rock solid EPP foam wheels make the landings very bouncy. I’ve since changed the main wheels to softer foam rubber Tundra wheels which has helped a lot but I’ve also found it’s better to land with half flap and a little more speed rather than use full flap. I ordered some parachutes to drop but they didn’t come in time for the first flight so I made up some very small gliders and some toffees with streamers to drop. The gliders were rubbish as were the toffees but the parachutes duly arrived and they’ve proved to be excellent. I now have six parachutes and they’ve been providing lots of entertainment and exercise for everyone who isn’t flying! You can see a parachute drop in this month’s video. I did manage to provide some extra entertainment on one flight. I took off as usual, raised the flaps during the climb out and suddenly both motors cut dead. I kept heading straight into wind and landed a few hundred metres down the field. As I walked to retrieve the model I tried to work out why the motors had stopped, I knew the lipo was charged. Then, as I reached the Bush Mule I saw the flaps were down and it dawned on me, instead of raising the flaps I’d pressed the throttle cut button…doh! Needless to say the other fliers present were surprised when I carried the model straight back to the patch and immediately took off again. I was forced to explain my stupidity and of course once they’d stopped laughing they barely mentioned it for next two hours…over and over again!

Speaking of pillocks, 1066 had a couple of ‘moments’ in January and I know he’d be disappointed if I didn’t tell you about them. The first one was when he launched his little Blitz delta and it immediately rolled straight into the deck. He looked down at the transmitter and we all saw the light bulb moment when he realised he’d switched the model to Blaze not Blitz! Never mind Steve, the first two letters were right…His second moment was a couple of weeks later, I saw him drive down the track but a few minutes later he drove back up it again. About half an hour later he returned, clutching the wings that he’d left on the bench!

I photographed Captain Slow’s part built Zagi at the beginning of November last year and featured it in Patch News where I mentioned that SMC say “Buy today, fly tomorrow”. Well this is how it was looking in mid-January. Perfection takes time…apparently…

But as the foamboard jet trend continues Captain Slow has finished his Mig-29…blimey, they must be quick to build!He’s fitted his with a Turnigy D2826/6 2200Kv motor and a 6×4 prop. It seems to fly just the same as the others although nobody is sure just how fast it will go as Captain Slow has never reached full throttle! As you can see he’s opened up the slot to reduce the prop noise and it seems to prove that the most important gap is the one in front of the prop. Captain Slow is also now building a Sukhoi SU-27…don’t hold your breath…

Gorgeous Gary has also joined the jet jockeys with a Mig-29. He’s using a drone motor, an RCINPOWER G2306 2200Kv, the same motor as I use. They seem good with a 6×4 prop and have plenty of power for the foamies.Gary had a big smile on his face at the end of the first flight … He’s had more flights with the Mig and is coming round to the joys of electric flight at last. And guess what, now he’s got the bug he’s building an SU-27!

Having enjoyed flying his Mig-29 for a few weeks Woody has now put together a Sukhoi SU-27. Being Woody he’s kitted it out with lights and I have to admit it does look impressive in flight, they show up well. The Sukhoi is a bit bigger than the Mig and has ailerons as well as elevons which means it’s better for high alpha stuff but not quite as quick flat out. I’ve also retro fitted a rudder to mine which helps with high alpha flying.

Page Boy was given an E-flite Texan for his birthday and very nice it is too. The E-flite models all seem to be good.It’s a 1500mm EPO foam model that comes pretty much complete, just a few screws are required to hold it together, the electronics, servos, linkages etc. are all pre-installed. The Texan comes with electric retracts which have strut covers, hinged doors, and scale wheels, and it has split flaps just like the full-size Texan. Page Boy asked me to do the maiden flight and being aware of the Texan/Harvard reputation for tip stalling I was slightly nervous. But the E-flite model is totally viceless, a real pussycat to fly, it took off beautifully, flew around very smoothly, and with the flaps down it just floated in for a gentle landing. You can see it in this month’s video.

Page Boy also sent me some photos of the latest ‘proper’ balsa/ply build that he has underway. It’s a Lindsay Todd design called a Woodpecker that has a 70″ wingspan. I thought it was an English Electric Wren, I’m sure that must have been Lindsay’s inspiration. Knowing Page Boy it will soon be finished and flying.

Most of you will know by now that on 10th January we had a Chinook fly directly over the patch at very low level. Fortunately we had just packed up flying and put the fence up when it appeared over the trees by the track we drive down, it flew right over the patch and out over the valley. It was very low, between 50 and 100 feet we reckoned and was going at speed. I quickly snapped a couple of photos but they don’t really show just how low it was. Had any models been in the air it’s doubtful the pilots would have had time to take any avoiding action. We are always careful about other airspace users, keep our ears and eyes open, and shout warnings as required but this served as a reminder that we must be extra vigilant. Contact has been made with the relevant authorities to ensure they know when and where we fly but ultimately it’s our responsibility to avoid full-size aircraft at all costs.

A few months ago Norwegian Nick won a Wingnetic in the big raffle and he brought it along to test fly in January.In the usual Norwegian Nick manner he has tarted up the original colour scheme a bit and made it look much smarter than standard. It’s certainly a lot better than my own very old and tatty Wingnetic! Sadly it didn’t quite get away from the launch and incurred some minor damage, but no doubt it will reappear and fly successfully soon. The Wingnetics are great little fliers and several members have enjoyed owning them.

Last month I pictured two models that were being put together by Newbie Nick and Matt. (Incidentally Matt needs a nickname, do you have any ideas?) They are both Pilot-RC Extra 330SCs with 67” wingspan, but Nick’s is a Gen 1 and Matt’s is a Gen 2. The Gen 2 has slightly different reinforcements and some other minor improvements. They were both hoping to fly them last week but Matt discovered some hinge problems with his so only Nick’s flew. It has a 400Kv Pilot motor swinging an 18×10 wooden prop, and a 6 cell 5000mAh lipo pack. Nick has fitted Savox 0252MG servos, and a Futaba R7008SB FASSTest receiver which is powered by a 6.6v life battery. Matt did the test flight which you can see in this month’s video. It flew really nicely and had plenty of power but the centre of gravity was slightly rearward and Matt wanted to make some slight adjustments to the throws and expo so he landed with plenty of battery capacity for another flight. Nick moved the lipo forward and made the adjustments on the transmitter and then Matt went to take-off again. But there was no power, the prop didn’t turn at all!After much fiddling, investigation, and helpful(?) comments from everyone present Nick gave up and flew his F-35 to cheer himself up! Back on the workbench he discovered the HobbyWing Platinum 100A Pro V3 speed controller was dead. Nick has sent it back and has just received a Castle Creations Edge Lite 100A to replace it.

Our patch is in a beautiful spot with lovely scenery all round, particularly to the south where views over the Solent and on to the Isle of Wight can be enjoyed.  Late one Friday afternoon I noticed a glorious sunset starting to form and thought what a lovely photo it would make for Patch News. There’s always someone to pee on your parade…

Time now for this month’s video, most of which was filmed by Captain ‘Heavy Breather’ Slow:Please watch the video full screen, it’s so much better with small models flying around. If the video won’t play for you click HERE

This month’s Finishing Funny comes from Dougal Entendre:

The flight attendant sees a suspicious looking couple on board, so she reports it to the Captain immediately.

“Sir, I think we have a case of human trafficking! There is a very pretty, hot and sexy female passenger on board who looks quite frightened, and the man she is with is a fat old slob who looks like a lecher, very sullen, mean and dangerous!”

The Captain responds, “Patricia, I’ve told you this before. This is Air Force One…”
