Patch News – May 2019

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:

Video time now which this month includes contributions from Dougal, Basher Bob, and Captain Slow:Please watch the video full screen, it’s so much better with small models flying around.

My girlfriend just asked me, “When we go to Egypt, can I go on a camel?” 
I said, “Of course you can” and booked it for her. She’s going tomorrow…
I’m leaving in three weeks and going by plane!

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…”

Patch News – December 2019

Happy New Year everybody! Hope you all had a fantastic Christmas and saw the New Year in sensibly(ish). I know some of you had office Christmas parties in December, I trust none of you got yourselves slightly inebriated…48032086_2192571957440010_8849379612002615296_oDecember saw the expected mixture of weather and we lost some days because of strong winds and heavy rain but many of us managed to fly on some of the better days. In particular, over the Christmas/New Year break the weather was very kind to us, light winds, dry, and not too cold. We’ve had the shortest day and already it stays light a little later each evening, it will soon be spring. One Sunday morning early in December it was very windy, much too windy for sensible flying, but four of the committee turned up ‘just in case’. The fence battery needed changing so we sorted that, and then 1066 decided it was a good mowing day, too windy for flying but nice and dry.

2018-12-09 12.09.20So the fab four spent a happy morning mowing and moaning, moaning about the lack of Dougal Entendre who was apparently nursing a hangover following his office party. Very little sympathy was shown!2018-12-23 10.32.48Someone even cleared a bit of a path at one side of the gate through the really muddy area to make access a little easier for us, I’ll let you work out who to thank for Woody’s Way!

Did you get any modelling presents from Santa? Some of you must have found some exciting parcels under the tree…they can’t all have been socks and underpants. Me? Well I did have a visit from a couple of Christmas Elves.2018-12-21 11.58.45Because I behaved myself Mrs Santa gave me permission to treat myself to an Avios Bush Mule from the HobbyKing pre-Christmas sale. Although I had a sneaky peek before Christmas I wasn’t allowed to start putting it together.2018-12-13 18.42.49I couldn’t have done anything to it even if I wanted to because with the usual Christmas paraphernalia everywhere and visitors stopping overnight all my planes and equipment had to be crammed back into my modelling room.2018-12-16 13.04.20No chance of even opening the box in there let alone putting it together, but now Christmas is over it will be built.

I also received a voucher for two flights with iFly Indoor Skydiving at Basingstoke. For those that don’t know, indoor skydiving is done in a sort of vertical glass wind tunnel that blows air upwards at up to 180mph and the ‘skydiver’ can (hopefully) float around freely. I’ll let you know how it goes, I’m sure I’ll look just as good as this when I do it!pic2Santa also brought me a tricky seaplane kit which I spent a few happy hours putting together on Christmas Day.2018-12-25 16.03.14

The foamboard fun-jet following continues to grow with myself, Woody, and now Bob the Builder flying the Mig-29s.2018-12-11 10.26.552018-12-11 11.56.27Newbie Nick has built a Lockheed Martin F-35 that comes in fictitious Royal Canadian Air Force Tiger Meet colours.2018-12-28 10.24.52 2018-12-28 12.03.50Unfortunately the first motor in Nick’s F-35 burnt out but he ordered a replacement and a few days later it was flying again. Nick let me have a flight with it and I can confirm that it has very similar flying characteristics to the Mig and the Sukhoi. Also like the others it was noisy at first but Nick opened up the propeller slot and now it’s much quieter.2018-12-28 10.24.29Woody absolutely loves his Mig and is doing all sorts of manoeuvres with it at low levels, things he’d never do with his other models. In fact, he loves it so much he’s ordered himself an F-35. Captain Slow has now received his Mig from Mrs Claus so we’ll be seeing it soon(ish), and Gorgeous Gary was so impressed seeing them fly on Boxing Day that he has just ordered a Mig for himself! Even Cream Egg wants to get in on the act, he emailed while in Madeira for Christmas asking for details, motor suggestions etc. Because they can land so slowly they are ideal for the Spot Landing competition and Woody was very pleased with this attempt but it wasn’t close enough to win.2018-12-11 11.31.35I was delighted with this attempt at the spot and was convinced I’d won, but 1066 promptly beat me…the swine!2018-12-14 14.29.41Despite them only weighing a few grams they will fly in ridiculously strong winds and one Sunday in early December both Woody and I flew the Migs in near gale conditions. Just the two of us plus Dougal Entendre bothered turning out that morning and it was definitely vital to weigh down the models to prevent them blowing away.2018-12-02 11.29.44Dougal was flying a much more sensible heavy model but Woody managed the lightweight Mig well. Not sure he looks too happy in the first photo but in the next one you can see his Mig looking good while Dougal was struggling way down wind. What I need is a camera that shows how windy it was that morning!2018-12-02 11.33.36 2018-12-02 11.34.49The only problem with this range of models has been the noise created by the prop running in a slot cut through the centre of the fuselage. We have been experimenting with different propellers, bigger, smaller, 3 bladed etc. with some success but the biggest noise reduction has come from opening up the size of the slot through the fuselage.2018-12-14 16.06.27 2018-12-14 16.06.18I’m not sure why but the Migs seem noisier than the Sukhoi and with three now flying, and a fourth on the way, it was important to make them quieter. Cutting the slots wider is simple, reduces the noise dramatically, and seems to make no difference to the flying at all. I’ve now also cut the slot wider in the Sukhoi with similarly quieter results.

I stumbled across a short video (just 38secs) of someone flying a very similar looking foamboard model somewhere in the Far East by the look of it. It’s both amazing and amazingly wrong for so many reasons, have a look and see what you think. It’s incredibly noisy, incredibly powerful, has lights around the edges, and there are two other similar models on the ground presumably marking out the designated flying area, utter madness!

Over the Christmas break I set up a WhatsApp group called PAM Flying Group. Matt suggested using WhatsApp a couple of months ago but as some members aren’t on it I can’t replace the ‘flying tomorrow’ emails, but maybe that will happen eventually. In the meantime if you want to join the group as an easy way to chat and exchange documents, photos and videos just download the free app (Android or IOS) and I’ll add you to the group. This is what Wikipedia says about it: WhatsApp Messenger is a freeware and cross-platform messaging and Voice over IP service owned by Facebook. The application allows the sending of text messages and voice calls, as well as video calls, images and other media, documents, and user location. At the moment it’s free of adverts but I understand that will change in 2019. It’s totally free to use, even for worldwide video calls so I imagine over 1 billion users are a pretty good group to target with adverts. Just let me know if you’d like to join the group.

At one of the December club meetings Percy Vears brought along his Lancaster and talked through the second part of his build blog. Ron is building the Lanc from the Tony Nijhuis plan and he purchased the plan, CNC cut parts, vacuum formed canopy, turrets and cowls etc. to make the project a little easier but there’s still a lot of work to do.2018-11-29 19.48.09 2018-11-29 19.48.18 2018-11-29 19.48.31The building side is now pretty much complete but there’s a long way to go before it’s ready to fly. Ron will be glass clothing the whole model, no mean feat in itself, and will then paint and assemble the various parts. It’s looking good so far, I can’t wait to see it completed and up in the air where I’m sure it will look amazing.

Last month I featured Matt Takhar’s new Velox which at 81” span is one of the biggest models in the club. After the first four flights Matt stripped the model down to check everything over and make sure there were no signs of any emerging problems. He sent me a few photos to use, the first of which gives a good idea of the size of the motor.IMG_0363 IMG_0362 IMG_0364The Velox is now back together and has had several more flights, Matt is getting more confident with it every flight. You can see snippets of flights three and four in this month’s video.

Ok, I’ll stop writing about the Velox now, Matt had an unfortunate ‘development’ on 28th December…IMG-20181228-WA0000I believe a new fuselage is on order from ProBuild. Fortunately all the gear, motor, speed controller, batteries and so on are undamaged, as are the wings and tail. I won’t go into what happened but it’s rumoured that Matt will be giving a talk at a future club meeting entitled ‘The do’s and don’ts of spin recovery’. Too soon? Sorry Matt!

One of the websites that I often check out is Flite Test and this month, as I’m still of a juvenile disposition, I was immediately attracted to the heading Check Your Crap. It was part of an article on Pre-Flight Checks and I thought it might be useful reading for PAM members. There’s a downloadable .pdf of a basic single sheet checklist that you can print off and keep in your flight bag, and also a short video of things to check before the first flight of a new model. To see it just CLICK HERE. The whole site is entertaining and packed with useful info, take a look for yourself.

Both Matt and Newbie Nick have treated themselves to Pilot Extra 330SCs. These ARTFs are 1714mm span, 1600mm long, and they are designed for either 20cc IC engines or equivalent power electric motors.

IMG-20181226-WA0003 IMG-20181227-WA0002 IMG-20181227-WA0004The electric versions need 400KV motors, 6 cell lipos and 18”x10” propellers. Matt says the supplier was out of stock of the recommended motor so they sold him an ‘upgrade’ one. It’s perfect other than the fact that it won’t fit!IMG-20181227-WA0003I should have some more photos and power train details when the models have been flown, probably in January.

Why men prefer aeroplanes to women:

  1. Planes come with instructions.
  2. Planes don’t have mother-in-laws.
  3. Planes don’t take forever to get ready.
  4. Planes don’t mind how many planes you’ve flown before.
  5. Planes are cheaper to maintain.
  6. Planes don’t mind when you Touch and Go.
  7. A plane will kill you quickly, a woman takes her time.

Patch News – November 2018

As I was away at the end of October this edition will cover the things I missed as well as the November highlights. The same applies to the video, it’s a little longer than usual but I think you’ll enjoy it, lots of exciting stuff featured.

November could be called the mucky month as early in the month Farmer George decided the field needed muck spreading. The spreading appeared to be much heavier than we’ve experienced before (it usually happens every third year) and was pretty horrendous the first couple of times we flew.2018-11-09 14.27.18 (2)But there was a lot of rain over the following couple of weeks which helped to quickly wash the muck in and the situation soon improved. Fortunately George avoided spreading on the patch and that remains in great condition.2018-11-09 14.26.58Captain Slow is ridiculously fastidious, one day I caught him trimming the edges with his nail scissors. As I write there’s still plenty of muck around the field but it’s nothing like as bad as it was and it’s getting better each week.

The weather was…er…Novemberish! There were some sunny days but also plenty of wet ones, and we struggled with lots of misty days, windy days and most unusually, some days that were both misty and windy.2018-11-16 13.49.19Never mind, the hardier members still managed to fly quite regularly and several new models were test flown.

Starting with what I missed towards the end of October, Catapult King brought along his repaired Grumman X-29.2018-10-21 11.07.53The model had flown successfully a few times earlier in the year but lacked the thrust that it should have had considering the power the motor was consuming. The model was damaged when Catapult managed a very rare bad launch so he took the opportunity to improve the ducting and add some very neat ‘cheater’ air intakes. The changes certainly improved things and the X-29 went away from the hand launch more positively than it ever had previously.Screenshot (46)See what you think of how it flies in this months’ video, I think it’s superb for such a challenging model.

In Patch News last month I featured Dougal Entendre’s new Velox but I wasn’t able to include it in the video.2018-10-21 10.13.08That’s been corrected this month and you can see how well the Velox flies, it even makes Dougal’s flying look good!

While I was away Dougal snapped a few photos for me to use. First up is the repair that Captain Slow has made to his Multiplex FunGlider using some carbon strips. The FunGlider appears to have a weak spot towards the rear of the battery access hatch and Captain Slow’s broke when he cartwheeled it on landing one day.2018-11-04 11.02.37 2018-11-04 11.02.44He’s added four carbon strips, one each side of the fuselage and two above the wing area and they have strengthened the weak section a treat. Next time it will break at the back of the wing (don’t ask how I know!).

But Captain Slow’s no fool, he’s has figured out a way to stop damaging fuselages, build flying wings! I snapped a sneaky photo of a new Zagi he’s building at the moment. It’s actually a JP SI 480 EPP Flying Wing from Sussex Model Centre but as far as I can tell it’s just a Zagi manufactured by Perkins.2018-11-09 15.41.03It’s 48” span and should end up weighing around 860g but the important thing to note is that on the SMC website it states “Quick to build – Buy today, fly tomorrow”. I took the photo on 9th November and he’d already been building it for about a week so by my calculations we should see it at the field around mid-December….2021.

The other photo Dougal sent me is of Nick Weatherley with his Max Thrust Lightning. I know both Nick and Matt Takhar owned Lightnings but both damaged them a few weeks ago and I think I’m right in saying that Nick has made one decent model out of the broken remains of the two.2018-11-04 11.18.53

A few weeks ago Gorgeous Gary sent me some photos of his latest project. The model is a 68” span Seagull Models Edge 540 for .61-.91cu.in 2 strokes or .91-1.00cu.in 4 strokes and the finished weight should be around 8 1/2lbs. As a long-term club member Gary is one who is still allowed to fly I/C models but of course they have to pass the BMFA noise test. I’m not sure what engine he’s fitted to the Edge but it’s definitely a 2 stroke and it looks like a .90cu.in to me. Personally I have my doubts that it will pass the test without a serious add-on silencer.IMG_0039Gary is the only member who still flies I/C reasonably regularly although we don’t seem to have seen him for a while, maybe he flew while I was away? Unfortunately I/C models definitely go against the ethos of the club these days and it’s a great shame he has turned his back on electric models after a couple of bad experiences with them. Compare the Edge to Dougal’s slightly larger Velox and you can see there is no reason at all to fly I/C these days and risk losing the flying field because of noise complaints.

Of course if you like the sound of a ‘real’ engine you can add a sound system to your electric model and have the correct engine noise of the original aircraft. That’s exactly what Woody has done with his Art-Tech Texan.texanWoody originally bought the Texan at the Blackbushe Show back in 2013 and added the sound system after the first few successful flights of the model. The system is specifically designed for the Texan so it will only reproduce the sound of a Pratt & Witney Wasp but some of the more advanced system will produce a variety of different engine sounds. Click HERE to see and hear the sound system in action. Woody has recently revamped the Texan as it was becoming a little tatty around the edges and he’s repainted it in the black scheme of one that’s based at Goodwood.

21483076071_47f69a8b62_b2018-11-13 10.45.37I was a little concerned about it being all black following my difficulties with orientation of Bob the Builder’s all black Dragon so Woody added some yellow highlights and a chequered cowl to help out. The Texan/Harvard is renowned for its’ tip-stalling tendencies and the Art-Tech model is no exception, it will bite if slowed up too much although Woody has managed to tame his model to a large extent with a few adjustments. Following the refurb he asked me to test fly the model and all was well although there were signs that it needs a little lateral balancing.2018-11-13 10.45.55 2018-11-13 10.45.46Everyone present watched the flight with interest until I came in to land, the most critical part of the flight. As the model was on the final approach I was watching the speed intently for any sign of the tip-stall when suddenly the sound of a full-size Spitfire grabbed the attention of everyone else. I couldn’t look away and completed the landing just as the Spit roared directly over the patch at fairly low level. Typical! Obviously my landing, that not a single person other than me saw, was absolutely perfect, so smooth and scale like in its perfection, the best ever…ahem!

Bob the Builder has been at it again. No, not crashing, he’s been building, and this time he’s produced Bob’s Bitsa.2018-11-13 10.58.33Bob tells me the fuselage comes from a crashed Splot but I think it was Bob version of the Splot as I can see several differences. He’s added a battery hatch to the top of nose, good idea, it’s much the easiest way of swapping out batteries. The motor is a HobbyKing PropDrive 2836 1400Kv outrunner and that’s linked to a 40A speed controller from RobotBirds. It’s very musical and plays lovely tunes when powered up, mostly to annoy everybody else in the pits I think. Bob uses both 3 and 4 cell lipos but says it’s better on 4 cells. In this month’s video I was flying it on 3 cells and it seemed plenty to me but I’ve since flown it on 4 cells and it had a bit more vertical performance. 3 cells produce about 300W and 4 cells around 500W so as the weight of the model is around 3lbs either should be plenty.2018-11-13 10.55.30Bob has fitted a tricycle undercarriage instead of the standard Splot taildragger arrangement. The fin and tailplane look like standard Splot items although Bob has enlarged both the rudder and elevator. The wing comes from a broken 5 year old Kyosho Calmato and he’s removed the centre section and re-joined the panels with no dihedral, this gives a wing area about 15% larger than a standard Splot. I hate to be complimentary but he’s made a great job of the covering and the Bitsa looks very smart. The choice of different parts is obviously a good combination as it flies really well, I thought it felt like flying a small pattern ship, it’s very smooth and it grooves well. Bob is still fine tuning things but at the moment the flight time is about 8 minutes so it’s a good model all round.

Jeremy Studdard sent me lots of information about his latest models. We don’t often see Jeremy at our field as he is also a member of the Chichester club (CADMAC) so he mostly flies at Thorney Island where they enjoy the use of the runway, although there are strict rules as to when and where they can and cannot fly.

The first one is definitely my favourite, it’s a 59” span Freewing Venom which is pushed along by a 90mm 12 bladed fan powered by a 6 cell 6200mAh lipo. Look at these excellent flying shots.Venom DH4 27-10-19 Venom DH5 27-10-19The model is equipped with flaps and electric retracts with sequenced front gear door and sprung oleos. The weight including battery is 6lbs 9oz (just under 3kg) and there is around 6lbs of thrust.CIMG8254 Venom DH7 27-10-19Jeremy says the fan produces a great jet like sound and isn’t too noisy. He also says this: For my powered aircraft on Thorney I go OTT with receivers, the main Rx has two receivers and I add two satellite Rx’s.  Blimey, that 3 more than any of my planes have, I wonder if that’s because he’s had problems or if he’s just playing extra safe? I won’t mention what make of radio he uses…

I’ll let Jeremy tell you about his next one: My other new aircraft this year, I was given it last Christmas but did not assemble & fly it till the summer, is the Sebart Katana 50E. Span 57″, 6lb 7oz including 5S 5000. Sebart have gone to extremes with the lightening holes. The whole thing is very fragile, including around the U/C. I’m even frightened to just pick it up, I have to do so carefully. While it can fly slowly it would not survive my landing skills on the patch, I’m too used to a 50m wide runway. I would want to fit Tundra wheels before trying the small grass patch.P1070812Jeremy also sent some video of his Olympus which you can view by clicking HERE. Thanks Jeremy, great stuff, I’m very jealous of the Venom…I reckon I could fly one from our patch ok…

Matt Takhar turned up in mid-November with a very special new model, an Aerotech Velox Revolution II.2018-11-18 11.33.092018-11-18 11.32.42We all thought Dougal’s Velox was big at 70” span and weighing almost 9lbs but sorry Dougal, Matt’s got a bigger one than you! Matt’s Velox is 81” span and the weight is around 15lbs, a seriously impressive model. It was assembled for Matt by ProBuild and they fitted it out with all the powertrain, radio, batteries etc. The motor is an Xpwr 40cc (obviously an electric motor equivalent to 40cc) and is 200Kv which means when run on a 12 cell lipo it’s able to swing a 22×10 Xoar Electric beech wood propeller. The speed controller is a Castle Phoenix Edge HV120 and the batteries are two 6 cell Gens ACE 3700mAh 22.2v 60C packs wired in series to give 12 cells (44.4volts).2018-11-18 11.52.052018-11-18 11.37.49According to the specs the set-up will pull around 90A and uses 4.1kW of power. Matt is using Futaba radio gear and the model is fitted with a Futaba R7008SB (S-Bus) (HV) receiver driving five Savox 1270 HV (30kg) servos. That lot requires a decent receiver battery pack so ProBuild have fitted a Gens ACE 5000mAh 7.4v lipo.2018-11-18 11.33.28 2018-11-18 11.53.59Matt had two flights the first time out with the Velox, the first one being understandably cautious but no problems showed up so, after a thorough check that everything was as it should be, he had a second flight that was more adventurous, although mostly at a sensibly safe height. As you’ll see in the video the model performs beautifully and has loads of power so, as Matt gets used to it, I’m sure we’ll be treated to some top class aerobatics.

Back to much more mundane stuff now!

Following the success with my foamboard HK Sukhoi SU-27 I splashed out £16.40 on a Mig-29 from the same range.2018-11-23 14.07.05 2018-11-19 14.09.58The Mig is similar but a bit smaller and easier to assemble than the Sukhoi and only has tailerons, no ailerons.2018-11-23 14.07.28 One of the reasons I liked the Mig was the colour scheme, it’s much brighter and more colourful than the Sukhoi and also, unlike the Sukhoi, the colour is printed on the underside as well as the top, it looks good in the air.2018-11-23 14.07.39I’m using the same motor/prop/lipo combination as in the Sukhoi and it flies well, lots of fun. Being smaller the wing loading must be a little higher so it’s not quite so good at the high alpha stuff as the Sukhoi and without ailerons it’s not quite so responsive at low speed but overall it’s a great plane for very little money. Woody, Captain Slow, and Bob the Builder have also bought Migs but as I write so far only Woody has finished and flown his.2018-11-23 14.27.01 2018-11-23 14.13.59He’s using the same motor as me but has fitted a 7” prop instead of 6” and it sounds much better so I’ll change mine to a 7” as well. I did the initial trimming of Woody’s and found it was bit unstable in pitch so Woody added some weight to the nose which made it much better. I then added some weight to mine as well and now they fly pretty much identically. Woody is getting on really well with his although the fact that they can be blown backwards when landing in any sort of wind is proving a little testing and this was where his third landing finished!2018-11-25 11.45.27But as it was at almost zero speed there was no damage at all so he’s happy. Both mine and Woody’s Migs can be seen in this month’s video. No doubts Bob’s will fly soon and Captain Slow’s sometime in the next year or two!

Video time at last: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

Patch News – October 2018

As I was away towards the end of October this Patch News will be a little shorter than usual and it won’t include any events that occurred in the last ten days or so of the month. No doubt other members will keep me informed of anything I missed and I’ll be able to add them to the next edition. Thanks to Dougal Entendre, Captain Slow, Catapult King, Dwayne Pipe, and Kryten for their photo and video contributions this month.

October saw the expected changeable weather and we missed flying one Sunday morning and a couple of Friday afternoons due to some pretty heavy rain and strong winds. But there were also some absolutely glorious days so we still managed to fly a fair bit, especially the Midweekers. The friendly bullocks that had returned towards the end of September were moved out to the lower field in mid-October which made life much easier for us. But the fence has done its job and the patch is in great condition, just needing an occasional mow now.IMG_4020TI don’t imagine the existing bullocks will be back in the field again as they’ll be off to a supermarket soon, but we’ll no doubt be joined by some much younger ones in a few months time. I expect they’ll prove to be really inquisitive at first and will probably be a pain until they get used to us.

I’ll begin with an event that actually happened on 30th September, too late for me to include in the last Patch News. Dougal Entendre was flying his HobbyKing Edge 540T and Cream Egg was flying his nearly new HobbyKing Voltigeur when there was a sudden bang, they’d had an unfortunate coming together. As is almost always the case when a mid-air occurs nobody was really to blame, it was just one of those things. Although…Bob the Builder (previously known as Basher Bob due to his fondness for mid-airs) was also in the air at the time of the collision. Just saying…! Cream Egg was definitely the winner of this skirmish, the collision pulled out the Voltigeur’s right hand aileron but, despite the aileron fluttering around still attached to the servo, he managed to land safely back on the patch.IMG_0870On closer examination we couldn’t find any sign of the impact, not a mark on the model other than the detached aileron. Presumably just the Voltigeur’s propeller made contact with the Edge, and even the trailing aileron was unmarked. Dougal however was not so fortunate, the impact tore the right hand wing clean off the Edge and despite Dougal’s best efforts at knife-edge flight the damage was too severe and the inevitable ‘hard landing’ occurred.2018-09-30 11.19.58 2018-09-30 11.20.09It was quite impressive, the wreckage was a long way from the ripped off wing, he managed several hundred yards of ‘flight’ before it reached its final resting place! Cream Egg had the Voltigeur back flying again a few days later but sadly the Edge has made its way to the big hangar in the sky… Never mind, it was a lovely day and there were plenty of members present to witness and enjoy the event!

Staying with Dougal, he sent me this photo of his Laius last month and it just happens to include his ill-fated Edge.2018-09-07 15.48.10-1The point of the photo was to show off the huge new rudder he’s fitted to the Laius in the hope that he’ll be able to prop hang the model. I’m not sure if it’s done the trick or not, but I do know he managed to snap the undercarriage and it’s now been replaced with an aluminium one, maybe that was the result of some failed prop hanging?

Stanley Knife has always had a penchant for larger models and during October he flew his 68″ span Black Horse PZL Wilga on a couple of the nicer midweek mornings. I really like this photo of it.2018-10-10 10.34.10I’ve covered the Wilga in Patch News previously but it was a long time ago and it’s worth repeating. The full-size Wilga was produced by Polish company PZL from 1962 until 2006 with over 1000 being built in many different versions. The version Black Horse have modelled is a 35A (no, that’s not how much current it pulls!) which was a mass-produced basic variant for sports aviation. It was fitted with glider towing hook, and was produced from 1968. It was fitted with a radial engine and the wingspan was just over 11M (36½ feet). The Black Horse model spans 1,720mm (67.72 in) and weighs just under 4kg (around 8½ lbs). Stanley has fitted a Turnigy Aerodrive SK3 motor from HobbyKing and says it produces almost 1300W on 8 cells swinging a 16×10 prop.2018-10-10 10.33.48 2018-10-10 10.32.38It certainly has plenty of power for the Wilga, the model takes off rapidly and then stooges around beautifully on much less than half throttle for most of the flight, only requiring more power to perform some gentle aerobatics. I shot some nice video of Stanley flying the Wilga, but unfortunately the only landing I captured was the only one bad one he did. You can see the flight in this month’s video.

I got tempted by a HobbyKing promotional email a couple of weeks ago, it was offering a Sukhoi SU-27 kit for just £7.64! Alright, so it was only a Glue-N-Go profile model made of foamboard and with a centre mounted motor but at that price it was simply too cheap to ignore. Unfortunately the cheapest postage option from the UK warehouse was more than £5 which seemed a bit excessive when the kit was so cheap so the obvious thing to was to buy two and effectively halve the postage. After a few seconds listening to a ridiculous voice in my head telling me I didn’t need another plane I pressed the Buy button. 1066 has already bought the second kit for a future club raffle so pay attention, you might be the proud owner of your very own Sukhoi soon!2018-10-15 15.13.002018-10-15 14.18.02The SU-27 has a wingspan of 750mm and is 1080mm long so is actually bigger than I expected. It also seems to be bigger than HobbyKing expected, the website says 650mm span and 900mm long, odd. The box contains nine pieces of pre-printed laser cut 5mm foamboard a plastic motor mount, a carbon tube, all the necessary linkages, and an instruction booklet. Oh, and 4 screws that are shown in the parts list but I have absolutely no idea what they are for! The builder has to provide a motor, 2 servos, speed controller, receiver, and 3 cell lipo. Unlike the stuff you can buy in art shops the foamboard is not paper backed and HobbyKing say it’s impervious to water. It all goes together very quickly, almost all with hot melt glue, and mine was ready to fly in just a couple of days.2018-10-15 14.18.29 2018-10-15 14.18.19A servo on each side of the ‘fuselage’ drives one aileron and one elevator half, so up elevator also gives up aileron, and the elevator halves also act as ailerons. I would have expected up elevator to be combined with down aileron so it seemed rather odd. So would it work in practice and how would the plane fly? The short answer is yes, brilliantly!Screenshot (38) Screenshot (29)Despite my doubts about the way the control surfaces operate they proved to be perfect in the air and the Sukhoi is nicely responsive to both ailerons and elevator. The specs say 1300-2200mAh packs can be used and I’ve been using 1300 and 1800 packs with no problems. With a 3 cell 1300mAh graphene lipo mine weighs 450g and balances at the suggested C of G with no lead required. It does feel very light for its size and that shows in the flight performance, it will slow right down to walking pace and still remain easy to control. Open the throttle and it will climb away vertically but I have to say it does become rather noisy at full throttle so I spend most of the flight stooging around at high alpha low speed where it’s most fun anyway.2018-10-15 15.13.03The noise is a result of the centre mounted propeller, pushers that have the propeller close to the wing trailing edge suffer the same problem. I’ll try a few different prop sizes to see if I can quieten it down a bit but otherwise it’ll be a case of avoiding full throttle most of the time, not a problem.

Captain Slow spent some time visiting old friends in France during October. Knowing they were into modelling he took his Multiplex FunGlider with him and they managed to enjoy some flying on the land alongside their house.IMG_0125 IMG_0198Captain Slow also discovered that his friend collects transmitters, he sounds like he could be Dougal’s new best friend although with only ten transmitters he’s not really in the same league yet!

1066 has been on a spending spree but not on new models, he’s recently relieved ex-PAM member Cyano Steve of his remaining modelling gear. From what I could gather he picked up a variety of top class 3D models (some in need of repair), batteries, and props for a bargain price. Cyano Steve used to buy top quality 3D models and 1066 has already started flying Steve’s old 51″ AJ Slick. The initials AJ stand for the designer Andrew Jesky, and Andrew is a world class aerobatic champion so he should know what he’s doing when designing a 3D model.2018-10-19 15.00.51 2018-10-19 15.00.581066 seemed to be getting on very well with the Slick on the first few flights that I watched so we can look forward to some impressive aerobatics in the future. Right now he’s still being careful with it but I’m sure that will change!

In Patch News a couple of months ago I featured Dougal Entendre’s shiny new Freewing Moray that had an excellent first flight but crashed on it’s second flight. Last month I explained that the cause had turned out to be failure of the speed controller and in October Dougal had another go with the newly repaired model.2018-10-19 15.00.22 2018-10-19 15.00.30He’d made a good job of the repairs and fitted a new motor and speed controller so all was looking good. Sadly it didn’t go well, the Moray rolled hard left from the launch and crashed. Presumably the motor torque caused the roll and Dougal’s application of right aileron wasn’t enough to stop it. Sadly, I’m not sure he’ll bother repairing it again.

Never mind, Dougal has a shiny new model to play with, or rather a shiny secondhand model. One of the models that 1066 bought from Cyano Steve was this lovely 3D Hobby Shop Velox and he’s now sold it on to Dougal.2018-10-21 10.13.08More details next month but for now, it’s a tad under 6ft span, weighs just under 9lbs, and Dougal flies it on 6 cells.2018-10-21 10.13.58 2018-10-21 10.14.09It flies beautifully and I have taken some video which you’ll be able to see in the next Patch News.

Here’s a selection of Catapult King’s and Kryten’s excellent flying shots that I held over from last month:IMG_4039T IMG_4036T IMG_3997T IMG_3985T IMG_0886 IMG_0885 IMG_0883Video time now: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

An airline pilot dies at the controls of his plane and goes straight to hell where the devil takes him to the ‘arrivals’ area. There are three doors, marked 1, 2, and 3. The devil tells the pilot that he will be allowed to choose his own hell, but first the devil has to take care of something else, and disappears for a couple of minutes.

The curious pilot sneaks a look behind door number one. He sees a pilot going through pre-flight checks for all eternity. He looks behind door number two, and he sees a pilot that forever finds himself trying to resolve emergency situations. He looks behind the last door, and sees a Captain being waited on hand and foot by scantily-clad stewardesses.

The devil returns just as the pilot gets back to his waiting position but he only offers the pilot a choice of door number one or two. The pilot says, “But I wanted door number three!”

“Sorry,” replies the devil, “that’s stewardesses’ hell.”

Patch News – September 2018

It’s autumn time again and September gave us a mix of some really lovely and some really terrible weather, but I suppose that’s what we should expect in autumn. The patch is getting better and better, it was mown regularly in September but it shouldn’t need many more cuts this year. I snapped this shot of Dougal Entendre, Norwegian Nick, and Woody all trying to stay awake while waiting for Captain Slow to finish one row with the mower.2018-09-14 14.49.01Farmer George moved the bullocks out early in the month so we haven’t had any problems with them but he’s recently said that they will be back shortly. Stop press: 26th Sept – bad news they’re back!

We were walking back to the cars after flying one midweek morning when we heard the distinctive sound of a Chinook. It sounded close but we couldn’t see it at first. The sound grew louder and louder and we suddenly spotted it. We’d made the foolish mistake of looking upwards but it was actually below us, down in the valley south of the field! It had climbed a bit by the time I got my phone out to take this photo:2018-08-30 12.36.10It went eastward, not over the field, but it was scarily low and could just as easily flown right over the patch. We enjoyed seeing it and I know we are always careful but it does serve as a warning to be extra vigilant if we hear a full-size aircraft heading our way. I managed to take a short snip of video which I’ll include in this month’s video.

Last month I featured Dougal Entendre’s new Freewing Moray that had suffered some damage when it crashed on just its’ second flight. Dougal had climbed to height to check out the stall but having stalled the model inexplicably failed to recover. Well Dougal is now pretty sure he has found the problem, an overheating speed controller. He says the model felt down on power as it was climbing so it seems likely the controller was overheating and when the model stalled there was little or no power to recover. Dougal sent me a photo of the offending controller, explaining that this was how it came out of the model, he hasn’t cut the heat shrink afterwards.2018-09-23 10.46.00He also confessed “That’s the last time I buy a sub-£5 40A (supposedly) ESC on eBay”.

A couple of months ago I pictured Norwegian Nick with his new EDF Hawk which looked great but didn’t have enough thrust to fly. Nick was using a 12 bladed ChangeSun fan and a 3 cell lipo pack and the consensus was that 3 cells weren’t enough to drive the ChangeSun fan, so he swapped it out for a 5 bladed Lander fan.2018-09-27 10.30.212018-09-27 10.30.02He’s now using a 4 cell lipo and a 4000KV motor which flies it beautifully as you can see in this month’s video.2018-09-27 11.32.21Nick currently only has one 4 cell pack so needs to raid the piggy bank to get more than one flight per patch visit.

Nick has also built a new Depron flying wing type model called E-Shark from the designer Graham Dorschell.2018-09-14 16.00.01It was free plan in RC Model World and this is what the Traplet website says about it: This is a simple sports or slope (using a folding prop) 41 in. span model design by Graham Dorschell built up from 5mm Depron using the ‘folding wing’ method, with some balsa and Correx board and using basic tools with two 9g servos for delta mix. With just a few parts to cut it turns into a quick model to fly with a 35mm 1500kv brushless motor, 60 Amp ESC, 8″ x 6″ prop and a 3S 2200-3000 mAh lipo.

Norwegian Nick has fitted his with a 3536 1400kv outrunner motor, a 60 amp esc, and is using an 8×6 prop.2018-09-14 15.59.38 2018-09-26 10.31.14It flies extremely well on a 3 cell 2700 lipo, only requiring around third throttle for stooging around so the flight times should be long. It failed to climb away from the first launch but then Nick realised the elevons were slightly down with the stick centred so he adjusted those and it went away beautifully from the second launch. I took some video of the E-Shark that you’ll be able to see in the next edition of Patch News.

There seem to have been some very strange fashions on the PAM catwalk at the field recently. Last month I pictured Woody’s refurbished Seagull Swift in its’ new Blue Angels colour scheme and this month I snapped the man himself with the model… ‘Built the model, bought the T-shirt’!2018-09-02 11.22.23Whilst Woody’s T-shirt is understandable some other fashion statements on the PAM catwalk are less so, here we have Dwayne Pipe modelling a rather snazzy pink bin liner that is usually reserved for carrying his crashed models.2018-08-24 15.33.43And Captain Slow (AKA Billy No Mates), feeling rather lonely, tried his “I’m hoping to become a Freemason” look!2018-09-14 14.23.30At least they made the effort and got to the field, 1066 just stayed at home and napped on the couch.1066-1Perhaps I should explain that he’s had an operation for a torn retina…ouch! I bet he’s really pleased that his wife Jen put the photo on Facebook for me to copy. Not sure what that odd lump on his head is though, maybe Jen clouted him for being so lazy! But don’t worry, he’s fine now and back flying again.

New members Nick and Matt are continuing their trend of having almost identical models! This month they both bought Sbach 342s but they aren’t the same, Nick’s is manufactured by Dynam and Matt’s is from HobbyKing.2018-09-16 11.49.38 2018-09-16 12.06.46First, a bit about the full size: The Sbach 342 is a two seater unlimited aircraft manufactured by XtremeAir GmbH, it’s the first ever certified all composite aerobatic aircraft. The lightweight aircraft features the solid Lycoming 6 cylinder air cooled motor and massive control surfaces to provide it with the low speed aerobatic handling needed in the most advanced and testing aerobatic schedules.

This is what Dynam say about Nick’s model: Straight out of the box you will find that this Dynam Sbach 342 model is lightweight, rigid and features a fabulous showroom finish using quality paint and decals that will look great at the airfield and in the air. Efficient and affordable power supply is guaranteed with the pre-installed quality ESC (with ample reserve capacity) and oversized 900kv brushless motor, driving a reinforced two blade nylon propeller will readily translate into an impressive flight envelope. Knife edge loops, 1 roll circles, flat spins, harrier loops, snaps, point rolls and prop hanging are performed with accuracy and grace that belie its compact 1250 mm span. Dynam have chosen an exceptional aircraft to replicate; they have delivered a lightweight EPO foam airframe in a quality finished, classic bold colour scheme and provided a near perfect power-train partnership. In short, it’s a model that can proudly and deservingly display the Sbach 342 badging.

So there you have it, we shall expect to see Nick performing knife edge loops, one roll circles etc. every Sunday…2018-09-16 11.47.39 Nick is using 4 cell 2900mAh lipos and the model had loads of power. You will see in the video that it appeared to have a slightly rearward centre of gravity but other than that it looked really good, a promising start.

I think Matt said he bought his HobbyKing Sbach second-hand from someone on Hayling Island. HobbyKing say this about it: The Sbach 342 is made from tough EPO foam, it is a really quick and simple build that requires no glue, the tail plane simply bolts on and the 2pc wings are a plug in set up, also ideal for transportation. The servos are pre-installed, the elevator/rudder servo’s being standard size with plenty of torque for aggressive 3D manoeuvers. Also pre-installed is the powerful brushless motor and ESC, for maximum performance and efficiency, a 2 blade prop is supplied. This fantastic looking Sbach 342 offers both the 3D pilot and sport pilot a very capable model with tons of performance and a whole load of presence, the large control surfaces are perfect for just about any manoeuver you care to throw at it. This superb Sbach 342 will keep you grinning from ear to ear, just make sure you have plenty of lipos to hand, prop hanging the Sbach is addictive!

According to the specs the wingspan and length are both 1400mm and the flying weight is around 2.3kg. Being second-hand I’m not sure if Matt’s has the standard set-up but it should have a 4250 800kv motor, a 70A speed controller and two standard size servos on the elevator and rudder plus two 9g servos for the ailerons.2018-09-16 12.06.23Matt is using 4 cell 5000mAh lipos so his model should have had a similar performance to Nick’s but it didn’t, vertical performance was very poor for a 3D style model. It has a lower kV motor so will need a larger prop than Nick’s model but in fact it had the same diameter but a lower pitch. So the next stage is a larger prop or maybe more cells. Other than the lack of performance the Sbach looked good and I’m sure Matt will soon have it performing well.

Dougal and 1066 are both happy flying low inverted and also both competitive so it was easy to wind them up with shouts of ‘Lower’ at every pass. I snapped a photo of each of them, not at their lowest points but you get the idea.2018-09-02 12.31.13-1 2018-09-02 12.38.02On this occasion I think 1066 came out on top…or should that be underneath???

Chris P Bacon was getting to grips with his new Ripmax Bolero during September when disaster struck.2018-09-02 11.45.06He was rather unlucky, it wasn’t even a real crash that caused so much damage, it was just a relatively minor hiccup on a landing approach. The problem nowadays is that the 3D models are so lightly built in order to give the best possible performance that a relatively minor mishap is harshly punished. The damage probably isn’t actually as terminal as it looks and I think it will repair fairly easily, I hope so anyway.

Two years ago a group of PAM members visited Vulcan XM655 at its’ home in Wellesbourne and were treated to a tour of the aircraft including the cockpit. This year on Sunday 16th September the 655 Maintenance and Preservation Society (MaPS) held a Members Day and, as both Percy Vears and Captain Slow have become members, they were present to see and hear the Vulcan’s engines being run up. When Percy built his lovely EDF Vulcan model he finished it in the XM655 colour scheme so he took it along on the day and found there was another Vulcan model there as well. Captain Slow took some photos and I downloaded some from the official website.P9160001 P9160015 Vulc-1

Norwegian Nick was given a part built model recently but had no idea what it was. Most of the model structure is built but it’s missing a fin, cowling, and cockpit so Nick decided to ask if anyone could identify it on the RCM&E forum (modelflying.co.uk). It took just 8 minutes for someone to identify it as a Chorus Gull designed by Brian Peckham and featured in RCM&E in February 2002. The design was loosely based on the Percival Mew Gull and was originally designed for a 60 size I/C engine but of course Nick will be using an electric motorto power this one.IMG_0940 IMG_0943Various posts on the forum provided photos and a link to a company selling the plan, cowling & canopy. Another post had a link to a build blog on different forum. Nick has already ordered the plan. He says the model is beautifully built and he’ll now get on and complete the model. Isn’t the internet a wonderful thing?

Thanks to Dougal and Captain Slow for their video and photo contributions this month. Kryten has also sent me lots of great ‘in air’ photos, here a selection, I’ll use some of the others next month:IMG_3972T IMG_4006T IMG_4016T IMG_3978T IMG_3993T IMG_4032T IMG_4054T

Video time now:

On an airplane, I overheard a stewardess talking to an elderly couple in front of me. Learning that it was the couple’s 50th wedding anniversary, the flight attendant congratulated them and asked how they had done it. 
“It all felt like five minutes…” the gentleman said slowly.
The stewardess had just begun to remark on what a sweet statement that was when he finished his sentence with a word that earned him a sharp smack on the head: 
“…underwater.”

Patch News – August 2018

August saw a change in the weather and we’ve gone from moaning ‘It’s too hot, I’m sick of this heat, we need some rain’ to ‘What’s going on, it’s supposed to be summer but it’s like winter’! The patch greened up very quickly when it rained and the speed of the transformation from dry dust bowl to lush green grass was quite incredible.2018-08-27 11.29.21The FARTS (Friday Afternoon Rural Trimming Society) sprang into action and gave it a good cut on Friday 17th but even by the Monday it was growing rapidly and when it was cut again on Friday 24th there was a lot of grass taken off. With the fence doing its job of keeping the bullocks away the grass is now in first class condition and the patch is better than it’s been for a very long time. The bullocks have learnt not to go near the fence and they leave the fliers alone most of the time so we have rarely needed to use the pen round the pits area. I took this photo one midweek day when we had just arrived and were busy lowering the fence, that’s not how we had the pits set up!2018-08-21 10.20.27 We had an ‘incident’ this month, John Warren managed to run his Albatros into himself whilst connecting the battery and the propeller did an excellent impersonation of a bacon slicer on his arm. He was extremely lucky that the cuts were not too deep and with the application of pads and a bandage the bleeding was soon stemmed. Initially we thought John was fine and we rang his wife to come and collect him but then shock kicked in, the blood drained from his face and he briefly passed out so we rang for an ambulance. John was laid down on a groundsheet with his arm raised and was looking much better by the time the ambulance arrived. The ambulance service was excellent (both the staff on the phone and the crew) and, once they’d checked his blood pressure etc., they soon had his arm cleaned up and re-bandaged. They said it didn’t need stitches and a trip to A&E wasn’t required so John’s wife drove him to Petersfield hospital where he was given a thorough check over, the wound redressed, and his arm put in a sling. Several things came out of the incident. Firstly, we must never get blasé about the dangers of an electric model once the battery has been connected. Secondly, the club first aid kits issued to members proved to be very good and we must all keep them with us whenever we fly, they are no use at home or in the car. Thirdly, it took several members to manage the situation, caring for John, directing the ambulance, replacing the fence and so on. Fortunately the bullocks stayed at the bottom of the field and didn’t need to be kept at bay, had they been more inquisitive the situation would have been much more difficult. I don’t want to be unsympathetic but John had been warned several times that he was not being careful enough with a ‘live’ model, hopefully he has learned from this. The incident should also serve as a warning to all of us not to be complacent, a model is dangerous from the moment the battery is connected and must be treated with the utmost respect.

Lecture over, onto more pleasant things now. Despite it still being summer there was a slight lack of new models in August but Page Boy turned up one morning with a very nice little North American AT-6 Texan.2018-08-15 10.34.22The British version is the Harvard but they are basically the same plane. Page Boy’s Texan comes from FMS and it’s an 800mm span model moulded in EPO foam. He actually bought it second-hand (but unflown I think) on eBay about a year ago but has only just got around to finishing it. Page Boy has fitted 1900Kv bell motor in place of the stock 1300Kv motor and uses a 3 cell 1000mAh lipo. At full throttle it’s giving 185W and as the Texan only weighs 450g (1lb) that’s an awful lot of power! The rest of the gear is as it comes, a 20A esc and four 9g servos.2018-08-15 10.34.34 2018-08-15 10.34.53As you can see in this month’s video the Texan flies really well. Page Boy was flinging it around at pretty high speed when I was filming but I had a flight with it afterwards and it is also well behaved when flown much more slowly, I was really impressed with it, a lovely little model.

 At Buriton recreation ground, before the last meeting of August, Dwayne Pipe flew his the latest version of his indoor/very light wind model, appropriately named Mark 3. Unfortunately I was busy flying my Hummer so I didn’t get to video the Mark 3 but it looked to be flying well, certainly much better than either the Mark 1 or Mark 2 did.2018-08-23 20.15.17 2018-08-23 20.15.21I asked Dwayne for some details of the model and this is what he sent: The Mark 3 is my latest attempt to home build an indoor flyer that uses my standard Spektrum transmitter. I have a couple of HobbyKing indoor planes already, which always come with their own low spec custom transmitter. The Mark 1 was a 15″ Depron Blitz that flew round in circles. The Mark 2 was a 15″ Depron Splot that was too heavy and could barely fly.

The Mark 3 is a 15″ own design based on the Splot planform. It flies on rudder, elevator and throttle control. The wings and tail feathers are made of 3mm Aero Depron. The cambered wing is heat moulded to a Clark Y section using a process I found in a recent RCME article. This construction makes a very stiff wing that requires no spar. The two wing sections are assembled with dihedral and then epoxied to a couple of 2mm carbon fibre tubes which form the fuselage, with the tail being sheet Depron. The whole thing including battery I estimate as about 30 grams.2018-08-23 20.15.30The electronics are a Bang-good 2.4G Micro DSM2 compatible receiver with built in brushed ESC. This was bound to my transmitter (eventually) and unlike most “blocks” comes with 4 servo micro sockets. It turns out that only HobbyKing make servos to fit these sockets. These are HobbyKing HK-282AS ultra-micro analogue servos at 2.2 grams each. The motor is a Bang-good coreless brushed motor fitted with gearbox and 5.5 inch propeller. Most importantly I discovered that these tiny aircraft require no down thrust or side thrust when setting up the motor. The battery is 1S 300mAh positioned to balance the model. The model is designed to take the wire wheels from another indoor flyer and will take-off from the ground.mark 3From initial flights it is very stable and should be ideal for indoor flying at Havant but probably too cumbersome to fly at the much smaller Medstead. Thanks Dwayne, I’ll try to get some video of the Mark 3 for a future Patch News.

It finally happened, Cream Egg eventually ran out of skill luck and crashed his Wot4…big time! He had to search for a replacement and this is his story: I spent a lot of time considering what model to purchase following the demise of my WOT4 through stupid pilot error! I ended up with a very extensive shortlist and then Steve Hastings (1066) kindly came over one evening for us to go through the choices and finally settled on the Voltigeur.2018-08-17 14.41.47Cost: £142, including motor, 45 Amp ESC, servos, prop and everything necessary other than the receiver. Assembly instructions: None. Simply 10 pictures on the box, which were very easy to follow. The servos and linkages are pre-fitted. These feature very nice ball joints and the servos are metal gear versions. The entire model is foam construction. Carbon fibre rod through the wings, which is typical. The wings are secured by small plastic bolts for easy disassembly. All one needs is some good Gorilla Glue to install the elevator/rudder/tailplane assembly. Connecting the linkages was reasonably straightforward. The worst operation is assembling the wheels and the fairings that surround them. This took more time than any other operation. Wheels are small and one already has a partial flattened surface and so I am inclined to change these and indeed increase the size slightly as the fairings will accommodate a larger diameter. The plane is designed for 3S batteries and demonstrations by Michael Wargo of Hobbyking show this to be a high performance aircraft with this size of battery and the 1000Kv motor/45Amp ESC. However, my 3S batteries were originally used in my Pandora when I started out and, as they have not been charged/discharged very much over the last year or so, I found them to be quite weak. Accordingly, I thought I would try my 4S batteries, which I have been using in the WOT4. A full load test with Andy‘s assistance showed a maximum power draw of 500 Watts at 40 Amps. Accordingly then, the 45 amp ESC supplied should in theory be adequate, but I plan to use the 60 Amp ESC out of my WOT4 instead. My last flight lasted eight minutes and came down with 57% on the 4S battery flown in fairly high winds of up to 17 mph. All up, I am delighted with the model and especially the way she handles, especially when landing. She is very light and when climbing vertically, it is really impressive. I believe it will be a great aerobatic model to further develop my skills.2018-08-17 14.42.14 2018-08-17 14.42.02The Voltigeur certainly looks good both on the ground and in the air, it’s a very pretty model that performs really well. You can see 1066 doing the maiden flight and some of Crème Egg’s latest flight in this month’s video.

I mentioned in last month’s Patch News that we had been visited by ex-PAM member Peter Mason and he’d promised to organise a quiz night for us. He duly came along to the first meeting in August and ran what turned out to be a very successful quiz consisting of 50 wide ranging aviation questions. The questions were well thought out and I was pleased that there were none of the ‘How many rivets were used to construct Mk.9 Spitfire’ type. Some questions were comparatively easy while others made our tired old brains whir quite a lot! Peter provided some very nice prizes for the first three places and I’m pleased to say that I won with just 25 points and Dougal and Woody tied for second place with 24 points each. I’m sure all those present thoroughly enjoyed the evening and we pass on our thanks to Peter.

Woody bought himself a new Wot4 recently and has been getting along well with it in August.WP_20180805_10_29_58_ProIt’s an ARTF wood E version, not the Foam-E and is identical to the one being flown by Bob the Builder. There could be trouble ahead…! Kryten snapped a couple of lovely flying shots of the Wot4.IMG_3964T IMG_3966TWoody has also finished a renovation job on his old Seagull Swift trainer. I think the Swift was Woody’s first model and it served him well but as it’s now around 5 years old it was starting to look a bit tatty.2018-08-27 10.32.31He decided to give it a US Navy Blue Angels colour scheme in the hope that the bright yellow underside would show up well even at 5000ft where he usually flies! It certainly works, looks very smart, and flies as well as it always did. Although Seagull sell the Swift as I/C or electric it’s really just an I/C plane that’s easy to convert.2018-08-27 10.31.56 2018-08-27 10.31.50Woody has fitted an old Thumper motor and runs it on a 5 cell lipo which gives it ample power to do all the aerobatics that you can expect from a trainer. Good one Woody, well done.

Having buried his original Kung Fu 1066 decided he missed it and has built another one.2018-08-24 15.10.27The first one was built for the annual club model event although 1066 seemed to have trouble counting fins as his only had one rather than the two shown on the plan. The club models were built from Depron and most flew very well, 1066’s being vastly over-powered as usual. He has built the replacement Kung Fu from foam board, the paper faced/foam core stuff that can be found in art supply shops etc. It’s very easy to work with although 1066 found the paper is easily damaged by tape when trying to hold it together while glue dries. I imagine cyano would melt the foam so UHU Por, Gorilla Glue or epoxy would be the obvious choices. The new one is to the plan apart from only having one fin (again!) and a slightly lengthened nose in order to achieve the C of G without requiring nose weight.2018-08-24 15.10.44 2018-08-24 15.11.12It seems to fly just like the original which is unsurprising as 1066 has fitted the same motor etc.

Dougal Entendre has finally got around to finishing the Freewing Moray that he bought some time ago from Alibaba in China. The Moray is intended to be flown on a 4 cell 1600mAh lipo using a 1400Kv motor but Dougal wanted to use his 3 cell 2200mAh packs so he has fitted a suitable 1800Kv motor instead and it flies very well.2018-08-27 10.17.46 2018-08-27 10.18.30Some of the first flight can be seen in this month’s video and all went well. Unfortunately the second flight didn’t!2018-08-27 11.09.25It was flying perfectly until Dougal decided to check the stall and, despite having ample height, the Moray didn’t recover as expected and crashed. At the time of writing the cause is undetermined but the damage didn’t look too bad so hopefully Dougal will soon have it repaired and flying again.

Chris P Bacon visited the BMFA Nationals over the Bank Holiday weekend and sent me some photos of the event.IMG_2653 IMG_2650 (1) IMG_2654He says the Vulcan had incredible presence in the sky but he didn’t feel the same about the Lanc. Maybe I’ve been flying electric too long but for me the petrol engines used in most WW2 models always sound terrible and with 4 of them in the Lanc I don’t think it would ever impress me. The jet turbines in the Vulcan just sound like…jet turbines.IMG_2648Chris P said the ailerons on the fun-fly model were the biggest he’s seen, I imagine they can be drooped a little to change the wing section for the Max Glide part of the competition, hence the size.IMG_2649He also said all the F3A aerobatic models were electric powered and used 10 cell lipo packs to give the performance. Nice! Thanks for the photos Chris P, more of us should make the effort to visit the Nats next year.
