Patch News – August 2020

Patch News – August 2020

I suppose after all that’s happened in 2020 nothing should surprise me but the August weather still came as a bit of a shock. It varied from several days of unbearable heat with the highest temperature recorded for 17 years to 70mph gales and of course several storms. Halfway through the month the bullocks returned to the field but they are mostly not interested in us, requiring just an occasional shooing away if they get too nosey. Late in the month the bullocks went and sheep are expected, a first since we’ve had an electric fence so things might get interesting!There was lots of flying, mainly by the usual regulars, but young Charlie, Chris Winkworth (WingCo), and our latest recruit Richard Osborn all flew several times and seem to be getting on well and are learning fast.

This month we heard the very sad news that Ron Vears’ wife Rosemary passed away on 15th August having bravely fought cancer for more than three years. Rosemary was a great supporter of Ron when he was our club Chairman for three years and she attended many of the club social events where she was always a happy and popular figure. Our thoughts are with Ron and we hope to see him flying with us again soon.

Several new models were flown during August, and the first I’ll feature shocked us all when it eventually made an appearance after about three years of building. Yes, Captain Slow’s Splot (or should it be called Splate?) has flown!It’s pretty much a standard Splot although Captain Slow has fitted ‘normal’ wingtips rather than the usual Splot endplates, thus increasing the span from 36” to 1m. The weight is 35ozs without the lipo. He is using a 3536 1000kv motor that he salvaged from his Durafly Ugly Stick and a 40A esc from a Wot4 Foam-E. Powered by a 2200mAh 3 cell lipo it swings an 11 x 5.5 prop and only pulls around 23A so the Captain should get decent flight times. He has stuck to the original single centre mounted servo on the ailerons and soldered up his own rock solid undercarriage. After such a long wait, tales of woe, problems with various types of covering and more, the flight was an anti-climax, it just flew as it should with just a little trim needed. I think it will become a firm favourite although maybe it’s a bit too quick for Captain Slow’s sedentary ways! You can see some of the first flight in this month’s video.

Page Boy first flew his Slec Fun Fly on 31st July, too late for the last Patch News. Page Boy says the laser cut kit was perfect and, although he was surprised to see so many lite-ply parts, the final weight came out at 4lbs which is fine. He is using a Turnigy G25 motor fitted with a 12 x 6 propeller and a 60A Hobbywing speed controller all powered by a 4 cell 2650mAh lipo. Page Boy originally bought some Futaba S3003 servos on eBay only to discover that they were fakes so he binned them and bought some standard sized metal geared ones from 4-Max instead.The covering is HobbyKing green and white film and he intends to add some trim later. I think the ‘cockpit’ needs to be black, it would look much nicer. The first flight went well and Page Boy seemed very happy with the performance.

Page Boy also flew a Wingnetic that he won in a club raffle ages ago but has only just got round to putting together. The maiden flight went well, in fact Page Boy said the Wingnetic flew better than he had expected, excellent.

When WingCo first came to see us he brought along a model that he had built. We checked it over and declined to fly it until it had been fitted with ailerons as we didn’t rate it’s chances very highly with just rudder and elevator controls. WingCo duly went away and fitted ailerons as suggested and also a rather large castoring tailwheel.Dougal Entendre was given the dubious honour of doing the first flight which proved ‘interesting’! Initially Dougal had trouble getting the model off the ground (he blames the tailwheel) and once it was in the air he had trouble trimming the ailerons. He soon realised the ailerons weren’t working as they should so quickly landed and then discovered that the linkage to the port wing aileron had come undone. Dougal did well to get it down safely without any damage so with the problems sorted it should be fine next time out. WingCo is also putting a trainer together.

Kryten captured this great shot of Dougal’s FPV Skyfun whizzing past John Warren’s Jocasta. “Coming through”!Dougal also captured some nice air-to-air screenshots of others members’ models from his FPV video footage.

Mini-Mike had a bit of a moment with his large scale P.68 Partenavia Victor one day. He had just taken off when suddenly both motors cut but fortunately he got down safely with no damage to the plane. On investigation Mini-Mike realised what had happened and confessed that when he intended to raise the flaps he’d hit the wrong switch and turned on Throttle Cut instead. Now what sort of idiot would do make an elementary stupid mistake like that…says the man who has done exactly the same thing with his own Avios BushMule…twice!

One model that didn’t survive the month was John Warren’s Albatross. The model has had rather a chequered history with several crashes and rebuilds. I’ve flown it several times and it’s flown well enough although I think it was a step too far for John’s piloting skills. John brought it along following the latest rebuild and asked me to test fly and trim the model. It took off ok although it needed quite a lot of aileron trim but when I began a fairly gentle right hand turn the starboard bottom wing abruptly failed, dropping down by about 30 degrees.I’ve never seen a wing fold downwards before, no idea what broke. Apparently, unseen by me, John had been repairing one of the interplane struts prior to the flight so I imagine that was a factor. There was nothing I could do and the Albatross spun in and was terminally damaged. It’s a shame as the model had looked good in the air on previous flights although, as can be seen in one of Kryten’s photos, it was prone to a variety of inflight failures.Look closely and you’ll see a trailing rigging wire as well as the more obvious loose tyre. Not to be defeated John has already started building a replacement Albatross, let’s hope he builds in some more quality this time.

On a more cheerful note Woody (or Major Disaster as Captain Slow now calls him) has built a rather nice Tucano from a Phoenix Model Products kit. He has fitted a Ripmax Quantum 25 motor, a 60A speed controller and an 11 x 7 prop. It runs on a standard 3 cell lipo in the 2200 to 3000mAh range and weighs around 3 1/2lbs with the battery. Woody chose the colour scheme of the RAF Tucano Display Team aircraft ZF448 and it looks very smart in mostly black but with some yellow trim. The test flight went very well with no problems. Just don’t mention bananas…It’s a lovely flier, quite gentle but fully aerobatic with no vices so it should prove to be the ideal model for Woody.

We had an interesting moment at the field one day when Dougal and 1066 decided to do some synchronised flying with their electric gliders. Dougal was using his Multiplex Blizzard and 1066 his ST Models Blaze, a pair that are reasonably well matched for flying together. Unfortunately they only got as far as pulling up to climb and turn at the end of the first pass when they collided! I don’t think of either of them was particularly at fault so I’ll blame them both equally. Immediately after they touched Dougal realised he had a control problem but he made it back to the patch and landed safely. 1066 on the other hand seemed to have full control but no power so he had to land out.When we looked at the damage we found that Dougal’s Blizzard had one aileron hanging off and the control linkage to that aileron has disappeared, while on 1066’s Blaze the whole nose complete with the motor was hanging off. Presumably the Blaze prop had hit the Blizzard’s aileron linkage which broke half the prop and the ensuing vibration tore the whole nose off! Fortunately both models were easily repaired and were soon flying again…but not together.

Rumour has it that 1066 also had another very near miss but this time without any damage. Apparently, one day when I was absent, he did a low inverted pass with one of his foam 3D machines in the normal ‘I can get lower than you can’ way when he actually scraped the fin along the ground before climbing safely away! Sadly nobody has any photographic proof of this event so I’ve asked 1066 to repeat it for me to film but so far he’s declined…chicken!

Newbie Richard Osborn has been looked after mostly by Page Boy and is learning quickly with his Wot4 Foam-E.Chas has also watched over Richard for a few flights, an experience that I think they both enjoyed.

I spotted this in a free paper the other day about the Coastguard trialling drones for search and rescue missions: Although we don’t fly drones the general public and government seem to link model aircraft to drones so any positive publicity for drones can only be a good thing, it makes a change from the bad press they normally get.

Recently I’ve been posting photos of the build of Dwayne Pipe’s latest edf model, a Folland Gnat. Dwayne drew his own plans for the Gnat, scaling everything up from an Airfix plastic kit that he’d been given for Christmas.The Gnat is 36” span and also 36” long, Dwayne confesses that he has increased the size of the wings and tail by 20% to reduce the wing loading. The completed model weighs 2lb 15oz with a 4 cell pack which gives a wing loading of 20.6oz/sq. ft. Power is provided by a 12 bladed 70mm fan from Banggood coupled to a HobbyKing 80A speed controller and this gives 2lb 4oz of thrust and pulls 50A. This month Dwayne got the Gnat all finished in a nice Red Arrows colour scheme and asked me to do the test flight. He was unsure if there would be enough power using a 4 cell lipo so he had set the model up to take either 4 or 6 cells. To me 4 cells felt to be providing enough thrust so we decided to do the first flight with that. Dwayne launched the Gnat and it simply climbed away with just a little down trim being needed. The Gnat performed the usual rolls, loops, stall turns, and inverted with no problem at all so after four very enjoyable minutes I landed it safely back on the patch and declared the model to be a triumph.Unusually Dwayne flies Mode 3 so I had lent him a Multiplex receiver and set the Gnat up on my transmitter in my usual Mode 2. Alongside my Multiplex receiver Dwayne fitted one of his Futaba receivers so after I had trimmed the Gnat he simply swapped the servo leads from my receiver to his own, copied the trim settings to his transmitter and flew the model himself, simples. The only minor problem Dwayne had was that when landing he found the Gnat floated on more than he had expected and he overshot the patch. Not a problem, the Gnat landed gently. But… Dwayne was in for a shock when he retrieved it…remember the bullocks were in the field! The Gnat had skidded through some very fresh poo which filled both air intakes! In this month’s video you’ll see snippets of both flights.

Kryten sent me lots of his superb flying shots this month, some of which you can see below. I update the cover photo of the club Facebook page most weeks and this week I used one that Kryten had taken of my Stearman.BMFA then posted it on their Facebook site, giving us a free plug and web link. It’s already had almost 2000 views! Video time now, this month with additional contributions from Dougal Entendre and Captain Slow, thanks guys. Please watch the video full-screen, it’s so much better with small models flying around.If the video won’t play for you please click HERE

A huge military Lockheed C-5 Galaxy was sitting on the tarmac near a little Cessna that was waiting to take off.
The Cessna pilot was rather nervous of the C-5 and asked the tower to check the intentions of the military plane.
Before the tower could reply the C-5’s huge nose cargo doors opened and a voice came over the radio booming:
“I’M GOING TO EAT YOU!”

Patch News – July 2020

August already and despite the Covid-19 restrictions many of us have managed lots of flying in July. The number allowed at the field is now a theoretical 30 but the booking system remains in place so if you want to fly please email John Wheeley beforehand, preferably at least 24 hours before. July saw several of the models built during lockdown flown for the first time, including Woody’s Hawker Hunter which finally got airborne. The patch is in excellent condition having been regularly mown by the FARTS (Friday Afternoon Rural Trimming Society).The sunny weather brought out lots of insects including this little grasshopper that hitched a lift on my F-22 Raptor.One of the Ikarus C42’s from Solent Flight based at Lower Upham airfield appeared to be practising engine out procedures when we arrived one morning, fortunately only one of them was directly over our field.

Last month I reported that Woody’s Hunter had been completed but we hadn’t managed to get it away from a launch. One of the problems was a sticky elevator snake and Woody managed to sort that. Then he did a thrust test which proved to be ok but the overall weight of the model was much more than it should be so in July we tried it with a 1500mAh battery instead of a 2200mAh. As well as saving weight it moved the centre of gravity slightly rearward to the correct position. Catapult King was seconded for launching and at last the Hunter took to the skies.It was a bit out of trim and very twitchy on ailerons but at least it was flying. When landing I discovered that it suddenly drops the right wing if slowed up but it survived undamaged. After some adjustments to the control movements and exponential we tried again and the second flight was much better, still twitchy but much better.I kept the speed up on the landing approach and got it down safely on the patch. Excerpts of both flights are in this month’s video. Sadly I think it will never be perfect because it’s just too heavy but it flies and looks great in the air

I also featured Norwegian Nick’s F-86 Sabre last month which was almost ready for flight. Nick flew it twice in July and it flies really well although, like the Hunter, it’s proved to be rather too twitchy on ailerons at first.The Sabre uses 4 cells rather than 3 but still manages to weigh less than the Hunter. After the first successful flight Nick went off to finish the colour scheme and it now looks superb in it’s Royal Norwegian Air Force ‘Jokers’ colours. He flew the Sabre again later in the month and it goes away from the launch well and flies beautifully although it did suffer a rather abrupt arrival caused by twitchy ailerons and loss of orientation I think. Fortunately there was no damage so with a little more tweaking it should be perfect. Some of the first flight can be seen in this month’s video. Nick also brought his Sea Vixen along to fly but after setting up the launch ramp and bungee he discovered that the Vixen launching hook was broken so he couldn’t fly it. Never mind, they looked brilliant together on the ground.

In the June Patch News I admitted to being jealous of Captain Slow’s model rack so I decided to make one for myself. Over the years my model room has become a model store and every time I want to do some building or repairing I have to empty the room of the models. She who must be obeyed is very understanding but does sometimes mention it when there are models on the landing, in the second bedroom, and especially on our bed. Luckily I don’t have any oil dripping I/C models these days! The obvious solution was to store the planes in the garage but unusually we do actually put a car in it so what I needed was a bench mounted rack. I was able to fix the rack directly to my workbench, a shelf, and a rafter so I didn’t need it to be free-standing like Captain Slow’s. This also meant it could be taller and hold more models, mine holds eight. I can stand the remaining small models on the bench around the rack and there are currently thirteen models on there. I spent just under £20 at Screwfix on some 21.5mm overflow pipe, a few 90 degree bends, and some T pieces. I already had the foam insulation.Note that it’s overflow pipe and fittings not water pipe. The fittings are just a push fit and would normally be glued but for my purposes I didn’t need to glue them so it will be easy to reconfigure for different models later on.Literally just as I was placing the last model in the rack and demonstrating to Doreen how brilliant it all was a courier arrived with a parcel for me, yes, another new model…how embarrassing, unsurprisingly it was mentioned!

So what could be in that thin package? It’s another foamboard jet of course and this time it’s one from Banggood.It’s a Yak-130 that has a part-box fuselage and I think it looks rather pretty, I hope it flies as good as it looks.I really fancied the JAS-39 Saab Gripen but, as well as being a few pounds dearer, for some reason the postage on it was £9.52 but only £1.65 for the Yak. I had some discount points to use so the Yak cost me just over £23 including delivery. I haven’t had time to build it yet but it arrived undamaged and looks good, watch for a report next month.

The Folland Gnat that Dwayne Pipe is building from scratch is coming along nicely and should be ready to test fly before too long. Early in July he sent me a couple of photos of the completed construction, ready for covering. Then at the end of the month he sent some more of the covered model, just got to hinge the control surfaces etc.

Catapult King recently bought the foamboard Sukhoi SU-27 that Dougal Entendre had won in a club raffle a while back. Dougal says he doesn’t like them so decided to sell it on rather than build it and discover that he was wrong! This is what Catapult said about it: It uses a 2200mAh 3s battery as the weight seems to be needed to get close to the CG, there’s a FrSky D4R-II receiver and a good old 30A HobbyKing ESC (Love em!). The motor was the hardest as I couldn’t find one for love nor money during lock down, but Gary came to the rescue and gave me a Turnigy D2826 2200Kv which he had spare, thanks Gary.  Catapult soon had it all put together and asked Dougal to do the test flight for him. The test flight went well and Dougal soon handed the transmitter back to Catapult who had no problems at all with the Sukhoi. I have to confess that I forgot to photograph Catapult with his new toy but you can see some of the first flight in this month’s video, including the part when Dougal almost buried it while inverted.

Certainly the biggest new model to be flown this month was Mini-Mike’s rather lovely P.68 Partenavia Victor. The kit was made by Modell Studio in the Czech Republic and at 2m (79″) span it’s a big one and it only just fits in his car. Mini-Mike has fitted the Victor with a pair of Tornado Thumper 3542 1250KV motors that are powered by a pair of 4 cell 3300 lipos. There’s plenty of room in there to fit whatever batteries he wants and one very cruel person was overheard saying that Mini-Mike will be useful when it comes to the lambing season! I’ve no idea what they meant… He said the 1250KV is too high and even using 9×6 props the motors are pulling more than the stated maximum current but he decided to see if it would fly and then decide what changes to make. He needn’t have worried, the Victor shot into the air despite the motors sounding very odd. Once he’d reached cruising height and raised the flaps the model burbled around on about third throttle but even then the motors didn’t sound too happy.It was reminiscent of Bob’s Easy Twin that had similar problems with erratic running motors which he eventually solved by replacing the Y-lead between the receiver and speed controllers. Anyway, the Victor stooged around for several minutes, looked great, and was otherwise problem free. Not wanting to push his luck Mini-Mike called landing, lowered the flaps, and discovered the Victor floats on a lot but made a nice landing just off the patch.

We were very pleased to have two prospective new members attend the field towards the end of the month and I understand Page Boy will be bringing a third one along with him soon. The first to appear was Chris Winkworth who initially came along one Sunday while we were sheltering from the rain in the barn. Chris brought along a model he’s been building on and off for a few years and it was given a thorough going over by us all, poor Chris! It’s a tissue covered semi-vintage style low-winger but currently only has rudder and elevator controls. The general consensus was that with almost no dihedral it’ll need to to be fitted with some ailerons before anyone risks flying it. Dougal Entendre got really excited when he spotted that Chris had a make of radio that he’d never heard of before! It’s a Detrum 2.4G GAVIN-6A 6CH. Dougal found the manual online quicker than you could say ‘Google’ and immersed himself in that for the rest of the morning. Chris was very heartened to know that even if the model doesn’t fly and gets smashed to bits he can always flog the radio gear to Dougal for a zillion pounds!

The second newbie was 11 year old Charlie who was brought along by mum Nadine. Charlie came equipped with an FMS Easy Trainer, a 1280mm spam foamie with a top mounted pusher motor powered by a 2 cell 1200mAh lipo. I think it must have come as a PNP including the radio gear as the transmitter is a small toy style one with manual trims. I haven’t seen manual trims for years, they seemed very odd having long been used to electronic ones.Bob the Builder gave the model a thorough check over with Charlie and made sure everything was as it should be and in doing so discovered the lipo was only 31% charged. None of us had any 2 cell packs with us so the test flight would need to be a very short one. I was nominated as test pilot and can report that the model was perfect, no trims required, it handled the fairly windy conditions well, and should be an ideal trainer for Charlie.

Knowing that we had some new kids on the block Captain Slow and Woody sorted out a buddy box set-up for the newbies to learn on which consisted of Woody’s Wot Trainer and a pair of Spektrum transmitters with a buddy lead. Captain Slow and I test flew the model and trimmed it out before handing the slave transmitter over to Chris to try. It all went well so after a quick battery change Charlie had a go and again everything went well.They both over-controlled as beginners always do but after a few minutes they were getting the feel for it and should be fine given so more practice.  We had enough lipos to give them both another flight and this time Dougal was given the Chief Test Pilot’s hat. He soon handed control over to Chris and all fine for a few minutes.But Dougal suddenly found he had no power although the radio seemed to be working ok. The model came down in the valley but fortunately the damage wasn’t bad, just the tail broken off. We initially assumed he had run out of battery but when checked it there was about 60% remaining. The motor was tested and appeared to be fine so that only left the radio. Further checks will be carried out but it would seem to be yet another case of b….dy Spektrum…

Over the winter Kryten built himself a new Swannee, a conversion of a single channel model that he had first built way back in 1966. I featured the new Swannee in June this year so I won’t bore you with the details again, suffice to say that this one has electric power, throttle, rudder, elevator, much reduced dihedral and ailerons. Kryten’s made a lovely job of the model and has been waiting quite a while for a decent day to test fly it. The Swannee is a low-wing model which was quite unusual back in the days of rudder only control and Kryten’s never flew very well.Kryten thinks that was probably more down to his lack of building skills and a decent building board than the model design so we had high hopes for the new version. We weren’t disappointed and, after the addition of some down elevator trim (not surprising as single channel models had to climb under power) Swannee flew beautifully. Success after just 54 years! Kryten managed to take some flying shots while I did the test flight and I shot some video while he was flying it. It was too late to add the video this month but you’ll be able to see Swannee in action next month.

Apparently I missed the fun one Friday afternoon when Woody landed the wrong side of a barbed wire fence and managed to get himself totally caught up on it. He spiked his left arm and caught the right leg of his trousers on the top strand was unable to move, remaining trapped until 1066 spotted his predicament and went along to free him. The sad part of the tale was that nobody took any photos of the woeful Woody! Captain Slow promptly re-named him Major Disaster and continuing with the ranking theme Chris Winkworth will henceforth be known as WingCo.

Kryten brought his decent camera along in July so I have some of his excellent quality flying shots for you to see, Nick’s Sabre in particular looks superb. Apparently the only usable shot he got of my Stearman was as I was doing an emergency landing because the battery was hanging out. A likely story Kryten, I’ll remember that…!

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

A Beechcraft KingAir (a ten seat, twin engine aircraft) had just left the runway on take-off when there was an enormous bang and the starboard engine burst into flames. After stamping on the rudder to sort out the asymmetric thrust, trying to feather the propeller and going through the engine fire drills with considerable calmness and aplomb, the stress took its toll on the Captain.
He transmitted to the Tower in a level friendly voice: “Ladies and gentleman. There is no problem at all but we’re just going to land for a nice cup of tea.”
He then switched to Cabin Intercom and screamed at the passengers: “Mayday. Mayday. Mayday. Engine fire. Prop won’t feather. If I can’t hold this asymmetric we’re going in. Emergency landing. Get the crash crew out.”

The aircraft landed safely but with the passengers’ hair standing on end.

COVID-19 UPDATE – LATEST INFO AS OF 18th JULY

As the Government’s limit on socially distanced groups is now 30 people we can remove the restriction on numbers. We have sufficient materials to create any size of pen for the pits should it be required.  However we will continue to maintain a booking system as should a Member be unfortunate enough to contract the virus, we will have a record as to who was at the Patch with him and so can advise those concerned of the need to self-isolate or get a test.  It will also allow any member who is concerned about flying in larger groups to avoid such days.  To this end Mark has kindly created a calendar that can be viewed by all Members in order to see who is attending on any given day. Members have been emailed the link but if you need it again please email John Wheeley,

Please note: You cannot edit the sheets; that can only be done by emailing John and he will add your name to the appropriate day.  Please give him as much notice as possible and if you decide not to attend it would help if you let him know.
When you open the calendar it will probably open at January 2020.  At the bottom are a series of tabs with every month for 2020.  Click on the month you wish to look at.
If you are uncomfortable with accessing this sheet just email John and he’ll tell you what’s happening.

Patch News – June 2020

As I begin writing this edition the country is slowly returning to normal, or at least ‘the new normal’ and many members have managed to get some flying in. The gradual easing of the lockdown rules has also made life easier for patch maintenance and it’s been mown several times which has brought it back to almost pristine condition although the lack of rain has caused it to go rather brown. The mowing has been led mostly by 1066 and Captain Slow has managed to keep the fence going throughout lockdown with regular charging and changing of the battery.At the end of May the bullocks returned and tended to join pilots alongside the patch but they’ve learnt not to touch the fence so haven’t caused us any serious problems. It would be nice if we could teach then not to wander across the take-off and landing areas at critical moments but overall they’ve been more of an irritation than a problem.Dougal Entendre tells me that Woody backed into the live fence during one session and rather disturbingly he seemed to enjoy the shock! Mike Smith did the same thing next time out but apparently found it less enjoyable. This time the bullocks visit was only a brief one and at the time of writing the field is bullock free again. Oops, you can ignore that, on Friday 26th Woody reported that the bullocks would be returning and sure enough they’re back.

During lockdown there were so many new models being built that I was overwhelmed with material for Patch News so I expected to be able to report on lots of maiden flights but that just hasn’t happened. With the restrictions of the number of pilots at the patch I haven’t attended as much as usual so I expect I’ve missed a few of the new models but will catch up over the next couple of months. Please send me details and photos of any new models I’ve missed.

One I haven’t missed is Captain Slow’s now infamous Splot. It’s infamous because the build of the really basic, fast to put together model took the Captain two years to complete, and I haven’t missed it because it still hasn’t flown! I sneaked a couple of socially distanced photos in mid-April when I dropped by Captain Slow’s place to collect the fence battery and the Splot was virtually finished then but 2½ months later it still hasn’t flown. He swears it’s all finished but doesn’t want to rush into anything. I must admit I am rather jealous of his model storage rack though.

I forgot to include one particular photo in the last Patch News and it’s one that I know you’d want to see. Bob the Builder and I were flying as soon as we were allowed and before the patch has been cut. Because the patch grass was longer than the rest of the field we left the fence up and flew from outside the circle, landing between the pits and the patch. At least that was the idea but Bob misjudged one landing and ended up here:I bet he couldn’t do that again if he tried! Luckily there was no damage, and the plane was ok as well.

Bob has now fitted a pair of new motors to his EasyTwin. The model flew well with the original motors but one of them made some fairly horrible noises at particular throttle settings and Bob could never be sure it wouldn’t suddenly seize up, especially bad news on a twin. So he’s splashed out on a couple of Tornado Thumpers from Overlander. I asked him for some comprehensive details of the new set-up and this is what he sent me:I just can’t get the staff… Oh, he did say “10 minute flights”. It can be seen flying with my BushMule in the video.

A couple of months ago Dougal sent me some photos of his venerable Fun 3 model. It’s now 40 years old having been originally built it in 1980 although the fuselage was rebuilt 4 years later following an ‘incident’!It’s been successfully flown with a variety of power sources, the first being a Meteor 40 with a tuned pipe (I bet that was noisy) and now of course an electric set-up which Dougal says makes it go better than ever.It is still using the original Skyleader servos which look rather out of place next to the tiny 2.4GHz Devention receiver, how things have changed in 40 years. But also notice the wing bolt plate that is looking very dodgy, I think that might have seen the end of the model had it not been spotted!

Last month I showed you a couple a photos of Woody’s almost completed Hunter that he’s built from the Tony Nijhuis plan. It’s now finished and I’ve had a few attempts at getting it flying but so far without success.The model looks nice but I wonder if it’s overweight as it just won’t go away from a hand launch. After several unsuccessful but undamaged attempts Woody is going to check the weight and measure the thrust to see if they are what the plan says they should be. It has the same fan and motor as my Raptor but feels about twice the weight although to be fair the Hunter uses a 2200mAh lipo and the Raptor only a 1500. We’ll see what the scales tell us.

Norwegian Nick brought his almost completed Sabre along to the field to show us one day. Like Woody’s Hunter the Sabre was built from a Tony Nijhuis plan and is using the same FMS fan but with a 4 cell rated motor. In theory that means it should have around a third more thrust so it ought to have plenty of power.The model is built to Nick’s usual high standard and is very nearly ready to be test flown. Personally I have to say that I have some doubts about the pilot, I’m not sure he can be relied on, he looks completely legless…

Several months ago, in the heady pre-lockdown days, I featured a Multiplex Stunt Master that Chas Butler had picked up for a good price at the LMA Much Markle show last year. The Stunt Master is made from Elapor (the Multiplex version of EPO foam) with carbon fibre reinforcements, has a wingspan of 870mm and weighs just 350g. The ready fitted hardware consists of a Permax 2206 1050kv outrunner, a 20A esc and three 8g servos. The prop is secured by a rubber O-ring so any unscheduled arrivals won’t damage the motor shaft, not that Chas will have any unscheduled arrivals. Both ailerons are operated by one servo mounted centrally in the fuselage above the wing, an arrangement that is pretty unusual on outdoor models these days but maybe it’s more common on indoor ones. Due to winter, windy weather, the lockdown etc Chas hadn’t got round to flying his new toy but towards the end of June the weather seemed perfect for its first flight. Despite being the hottest day of the year so far the conditions weren’t actually ideal as there was a reasonable breeze blowing from the east which always means turbulence from the trees. But the first flight went very well and even subsequent flights in the increasing wind were fine.Chas was delighted with the model and it certainly looked good in the air. The flights I watched were with the rates in the ‘standard’ setting, wait until he tries ‘3D’ setting! You can see some of the maiden flight in this month’s video.

Towards the end of June both Captain Slow and I started flying FPV again. We both had some successful flights without any problems but then Captain Slow decided to fly his SkyHunter normally, ie. not using goggles. It was flying fine although the turbulence off the trees but getting worse as the morning wore on, especially low down. I was trying to get some flying shots of the model so asked him to do a low pass…big mistake, entirely my fault. It’s a shame I was taking stills rather than video but you get the idea, the pass was a bit too low for the conditions. Fortunately there was no damage other than a cracked joint in the nose and a big dent in Captain Slow’s pride!

Dwayne Pipe sent through a couple of photos showing how he’s progressing with his Folland Gnat. It’s a totally scratch built model, Dwayne has drawn up his own plans, scaling everything up from an Airfix kit.He began by producing a kit of parts and now has the wings almost done, I assume there will be a carbon joiner.Dwayne is going to fit a 12 bladed fan from Banggood which he’s tested on an 8 cell lipo and gives around 1.5kg of thrust so in his words the performance should be ‘lively’! Dwayne is building up quite a bit of experience with EDF set-ups, his scratch built TSR2 goes very well as you can see in this month’s video.

Catapult King has now repaired his own design Yellow Tail following an early flight ‘incident’ when he discovered that models with very thin tapered wings are prone tip stalling, something that’s all part of the learning curve I’m afraid.He based it on 1066’s Pichler HiSpeed, taking the basic sizes and then modifying them to his own requirements.This time out Catapult kept the speed up and the Yellow Tail performed well with no problems.Catapult also flew his Bug, a model he built from the Flite Test plan, which is constructed almost entirely from Depron so is very light. The day was rather breezy so hardly ideal Bug conditions but it just about coped.

The weather has been quite amazing for the last couple of months but it became cooler and windier at the end of June. On Sunday 28th Dougal Entendre, 1066, and Bob the Builder had booked a slot and they all flew despite the strong wind. Here is Dougal’s report on the morning: When Steve and I met up, we decided to go in the lower field as we both had hand-launchable models and didn’t fancy dealing with the cattle. I flew the Sportjet and the Blizzard, and Steve flew his Mirus. The wind was strong but not too bad. Then we saw Bob going in the gate of the upper field, so I went over to tell him where we were. Steve went back to the car to get his hotliner out as there seemed to be lift about. Bob flew his Walrus and made the most of the lift which we found over the bottom of the field.The wind was coming up from the south-west, so some of it may have been slope lift, but there were strong and bumpy thermals coming through too. On my second Blizzard flight it started to rain quite heavily, so Steve and I landed, and Bob left at that point. The rain soon stopped though, and I still had 87% in the Blizzard battery, so we flew again. I must have spent fifteen minutes or so working bumpy thermals, and Steve did the same with his hotliner. I landed with 55% still left in the battery! So all in all a surprisingly enjoyable morning, and we were glad we made the effort! Thanks Dougal, sounds fun, sometimes the more challenging days turn out to be really good.

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

COVID-19 UPDATE – LATEST INFO AS OF 30th MAY

The Government has issued revised lockdown rules that take effect from Monday 1st June when groups of up to 6 people from different households may meet in outdoor spaces providing they comply with the existing social distancing rules, which means that up to 6 Members can fly at any one time.

Having discussed the matter with the Club Committee the following revised rules for flying at the Patch have been agreed with effect from Monday 1st June 2020:

On all days’ of the week except Friday afternoon and Sunday there is no need to book a flying slot with John Wheeley.  That said if a Member (Andy usually) plans to fly they are asked to circulate their intention to all those on Andy’s email list of mid-week flyers.  Those intending to join the instigator of the flying session are requested to advise all those on Andy’s list of their intention to fly.

Friday afternoon will revert to “gardening” and to avoid more Members than the 6 allowed turning up, Members are asked to book their visit by email to John Wheeley.

Similarly, on Sunday morning, any Member intending to fly is asked to book a slot with John Wheeley by lunch-time on Saturday and if more than 6 apply, then priority will given to those who work from Monday to Friday.

If any Member feels uncomfortable about flying as a group of up to 6 Members then they should contact John Wheeley and a day will be allocated to them to fly, BUT there must be a minimum of 2 Members present as there are bullocks in the field.  They will also be responsible for arranging their flying companion.

Please do remember that Members MUST maintain a separation of 2 metres at all times; this will require some care both in the pits when the bullocks are in the field (now) and on the flight line.

If any Member has any questions please don’t hesitate to contact John Wheeley.

COVID-19 UPDATE – 11th May


The BMFA have updated their guidance for model flying following the Government’s relaxation of their “stay at home” rules.  You can read the update here: https://bmfa.org/News/News-Page/ArticleID/2653/FURTHER-IMPORTANT-UPDATE-PLEASE-READ-COVID-19-AND-A-RETURN-TO-THE-SKIES, which is based on: https://www.gov.uk/government/publications/staying-alert-and-safe-social-distancing/staying-alert-and-safe-social-distancing.

The Patch grass is quite long and this will prevent most models from ROG launches and also the bullocks are in the field.  We should adhere to the Government / BMFA guidelines which means only two Members can be at the Patch at any one time; this means that cutting the grass – which will have to be removed from the Patch – is probably not an option.  We also don’t want Members to turn up on the off-chance of flying as this will lead to wasted journeys and, understandably, frustration.

The Committee have agreed the following plan:

Two Members at the Patch at any one time who are socially distanced and follow the BMFA guidelines. As there will only be two Members, when the bullocks are in the field flying can take place from within the main Patch fence with landings where so ever you choose.

In an effort to provide all those who wish to fly with equal opportunity the Chairman will run a booking sheet.  In this way if for example you fly on a Wednesday, unless there are no takers for the following day or days, you won’t get a slot to fly again until all who have requested one have flown.  If you cannot take up your allotted slot then if it’s for the following day or two please use the Club’s WhatsApp Group to alert other Members who may wish to take the slot.  Priority for slots at weekends will go to those who can’t fly during the working week.

Some other points of detail relating to the proposals above:

If you wish to fly on the following day the Chairman will need to be informed by 8:00pm at the latest and if there is a free slot he will advise you by text message.  To do this he will need your mobile number so please included it. Please plan ahead if you can.

Whilst the weather looks very reasonable for the next 7 to 10 days, this can change and if you are unfortunate enough to choose a day that subsequently becomes un-flyable, then you’ll just have to take the next available slot.

Covid-19 update and other news from the BMFA

Dear BMFA Member

We hope this email finds you well.

Unfortunately, the Government extended the current lockdown restrictions for a further 3 weeks at least from 16/4/2020. This is very frustrating especially as the weather has been excellent recently. However, if we all metaphorically stick together (literally would not be in the spirit of social distancing!) we will be doing our bit to help bring this national emergency to an end sooner rather than later.

We have received several calls and emails from members of the public who have witnessed model flying taking place during the lockdown. We are aware of at least one case where the Police were involved moving some model flyers along. Of course, they may not have been BMFA members.

Everyone should consider the effect of their actions in this time of crisis; not only the extra risks involved in going out but also how it reflects on the sport we all love.

Our advice remains to always follow the government advice which is: only to leave home for a limited number of reasons, these are: –

  • shopping for basic necessities, for example, food and medicine, which must be as infrequent as possible.
  • one form of exercise a day, for example, a run, walk or cycle – alone or with members of your household.
  • any medical need, including, to donate blood, avoid or escape risk of injury or harm, or, to provide care or help to a vulnerable person.
  • travelling for work purposes, but only where you cannot work from home.

 

This does of course give many of us plenty of time to finish off those winter projects or even to get a head start on another project, hopefully it will not be too long before we are all back flying.

We are aware that many of you who have 3D printers are actively involved in producing PPE for various essential workers, very well done you should be extremely proud of your efforts.

CAA Operator ID’s

Operator ID’s for those who requested CAA registration through the BMFA before February 10th have now been added to the membership portal and individual members can view these from the ‘Member Details’ section of their profile.  For those who requested CAA registration after 10th February, the next upload to the CAA will be taking place on 3rd June and you will receive your operator ID’s direct from the CAA shortly afterwards. These will also be added to the portal.

Website Updates

As mentioned in our last email the new events calendar is now up and running at https://events.bmfa.uk/ and events are starting to be added. The next website update we are working on is a newly updated classifieds section. This is not ready yet and we will give everyone plenty of notice before the changeover. It is almost certain that to place adverts and reply to adverts that you will need to access the classifieds section by first logging in to the Go Membership portal. The aim is that this will give increased security especially as wanted adverts, which are the adverts most targeted by scammers, will only be visible to logged in current BMFA members.

Finally, as reported in earlier correspondence, despite the lockdown requirements the office switchboard is till being manned and emails still monitored at this time. The day to day work of the office is continuing and the BMFA are still working hard to protect and promote model aircraft flying in all its forms.

That’s all for now.

Stay well. Stay at home. Protect the NHS and save lives!

Best Regards from all at the BMFA.

2.4GHz radio use & installation help sheet by Mike Ridley

As some of you will know I had my radio go to failsafe mode a couple of times last week. A low power range check appeared to be ok so I took the gear to Mike Ridley of Model Radio Workshop and he found that the receiver aerial had a break in the coax shielding where it exits the case. I had seen the insulation on the aerial had split but didn’t realise the coax shielding was damaged so I had simply put a piece of heatshrink tubing over the split. The damage reduced the range, hence the failsafe, but the low power range check had not shown the problem. Mike fitted a new aerial and it’s now all good again.

Mike is the official service agent for Multiplex and many other makes and his services are very good value, he is thoroughly recommended. He is based in Sholing, Southampton so it’s a quick and easy trip for most PAM members.

While I was there Mike gave me a sheet he has compiled that covers some of the common problems he comes across and which contains some useful tips. He’s given me permission to use it: 

2.4G Radio use and installation help sheet

With regards to problems with 2.4G radio, as 2.4G radiation is quite directional, aerial position at the transmitter and receiver is quite important.

In the case of the models with carbon or metal in the way or close by the aerials this will have an effect on the aerials and will reduce the overall range.

Even the wires to the servos will also affect the range, so having any of these items close to the aerials will narrow down the active part of the aerial receiving the signals from the transmitter.

With all carbon models the only thing you can do is to get the aerials outside of the model, it has been found that having the aerials some distance behind the wings is the best. Having the aerials in front of the leading edge of wings will tend to give lock out and failsafe operation as the fatter part of wings will hide the aerials with the model in given positions.

I suggest that once a model has its radio fully installed that you take the model to the edge of its range by using the power down setting on the transmitter and then at the edge of range position the model in different angles and attitudes and see if you can lose the radio link. If this is the case then look at the aerials positions within the model to see if they are being compromised in any way.

UBec use
When using UBec power supplies avoid mounting the UBec close to the receiver as this can cause direct interference. I suggest when you first install a UBec carry out a short range check with and without the UBec if you find a significant change in the range then have the UBec checked out or replaced. This problem can also apply to some speed controllers that are now also using UBec BEC circuit.

NiMH batteries
One of the other problem with today’s modern radios is the batteries, as we’ve been forced to use NiMH battery this makes the possibility of battery voltage collapse much more likely, as NiMH have a much higher internal impedance sudden high loading of the battery can make the voltage collapse causing the receiver micro-processors to reset. If you have a lot of servos in your model you should consider using Eneloop batteries as they have a much lower internal impedance and can cope with high loads.

Transmitter aerial position
I recommend that the aerial be put into the vertical position as the signal that is radiated from the aerial is polarized in vertical plane and is more likely to reach the receiver than in the horizontal plan. This also avoids the tip of the aerial pointing directly at the model which is where the radiation is at its weakest.

Third party add-ons
If you are using third party add-ons with your 2.4G radio be aware that some units may radiate interference that can get into your receiver, items like height limiters etc. Mounting such items on top of your receiver can lead to lock outs and failsafe operation, try to avoid mounting electronic items close to the receiver as even a CE marked thing may still upset the receiver.

2.4G with boats
Because boats are at ground level and in water the strength of the 2.4G signal is very weak across the water, so the aerial/aerials should always be mounted in the vertical where possible in a tube, fitting the aerials under the decking can lead to loss of control when the model banks especially as the aerial get closer to the water level.

Once again metal or carbon parts in the model will deflect the 2.4G radiation so avoid mounting the aerials close to these types of materials.

Range checking
Using the power down button on your transmitter to test the range does not tell the whole story. If we say that the power down output is 10 milliwatts if there is a problem with the R.F. module/board inside your transmitter then you could have just 10 milliwatts when in full power mode.

This effect has caught many people out, one of my customers after crashing a model then carried out a power down short range check on a second model and everything seemed fine, and ended up crashing another model.

I suggest if you get any signs of loss of control with a model, carry out a full range check or at least a test that is greater than the distance where you lost control of the model.

Common faults with 2.4G R.F. in transmitters are fractured aerial wire, damaged aerial, loose aerial, aerial connector not fully home, faulty R.F.I.C. in the R.F. module, all of the above are quite common in most makes.

Airbrush with compressor, and bench grinder for sale

As most of you will know our President Don Eades is sadly now having to be looked after in a care home. Most of his modelling stuff has already been sold but there are a few odds and ends left, the most valuable items being an airbrush set-up complete with compressor, and a bench grinder.
Is anyone interested in either of these?  If so please make an offer Mark Agate.

NO FLYING on Sunday 12th May – Field being using as a car park

Please note that next Sunday 12th May the field will be used for car parking for the Green Fair being held at the Sustainability Centre so no flying will be allowed.

Some of us will probably fly on Saturday instead, keep an eye on your emails.
