Patch News History

There seems little point starting this Patch News in the usual manner of talking about how the weather treated us…every single day was hot and sunny, too hot for many of us! Of course the grass has barely grown at all so there’s been no work for the Friday Afternoon Rural Trimming Society (FARTS) to do.  The bullocks made a brief appearance before returning to the lower field but barely approached us anyway, I think it was too hot for them to bother.

A few PAM members attended the Southern Area BMFA Southern Gala at Middle Wallop on 7th July. Dougal Entendre flew his Mini Blitz and large Spad, and I flew my little Sharkface. I’ve included some footage of Dougal’s Spad flying in this month’s video, it’s an impressive model. There were some interesting models present and I was particularly taken by Mike Spencer’s Swannee, a model that I can remember being a free plan back in 1966.The Swannee was designed for single channel radio with ‘rudder only’ control and it was very unusual in that it was a low winger, almost unheard of for rudder only. At the time I was as school with current PAM member Kryten and as his real name is Graham Swan he felt obliged to build one! I was desperate to have a radio set but couldn’t afford one from my pocket money so my parents said I could either go on the two week school trip to Italy or have the radio set, you know which I chose! Kryten and I each bought an RCS Guidance System made by Radio Control Specialists Ltd, I think the cost was around £17. Although we both sold the radios many years ago Kryten still has the box and instruction pamphlet from his and he was good enough to send me some photos. Those were the days! Mike Spencer’s Swannee is 3 channel, rudder, elevator, and throttle, and of course it has an electric motor instead of a small glow-plug or diesel engine. For control he uses a modified RCS 10 channel (for a maximum of 5 surfaces in 2 directions each) reed set. Reeds set were what wealthy people used before modern ‘proportional’ radio sets were invented and instead of sticks they had sprung loaded toggle switches for each control. To turn left you pushed the aileron switch to the left in a series of pulses to achieve the radius of turn you wanted. Mike’s set has been converted to 2.4GHz but retains the reed switches and the model flew well, unlike Kryten’s original single channel version that he recalls as being awful!

Back to our patch now and Page Boy brought along his Dawn Flyer to test. The Dawn Flyer was designed by Lindsay Todd who describes it as ‘a latticework lightweight that summons the spirit of aviation’s pioneering age’. It was featured in RCM&E in July 2013 and Page Boy bought the plan and CNC cut wood parts from Sarik Hobbies. He has fitted a Turnigy 3536 1250Kv motor coupled to a 3 cell 2200mAh NanoTech lipo via a Hobbywing 40A esc. The servos are Turnigy MG14 9g digitals. As you can see he has made a lovely job of building the model and covering it in Solartex, it really does look amazing. So how did it fly? Beautifully of course, but no need to take my word for it, you can see it in the video later.

Next up is Bob the Builder’s latest creation, a Dragon! It seems his New Zealand based grandson loves dragons so when Bob saw a plan for a Bat in the May 2016 RCM&E he made some changes to make it more dragon like. The main change was to do away with the normal tailplane and fin, opting instead to design his own V-tail. He added half table tennis balls for eyes and has fitted LEDs under them and also fitted LEDs in the mouth.The Dragon wingspan is 36″ and the flying weight with a 2200mAh 3s battery is 2kg.  The Hobbyking 2836 1400Kv PropDrive motor is fed via a 40A esc and swings a 9×6 prop. The Dragon is all balsa construction, the fuselage is covered with glass-cloth and Easykote, and the wings are film covered. Originally the whole model was black apart from one half of the V-tail which is red but as I discovered on the first flight the orientation was a major problem.There is no dihedral at all and the all black wing proved very difficult to see. As you can see in the video the first flight only lasted a few seconds before I lost orientation. Fortunately the damage wasn’t too bad and Bob added some white trim on the underside of the wings for the second flight. Orientation was much better and the Dragon flew well although I think it could still do with a bit more trim to help. Overall is now flies nicely and is certainly different, it looks good in the air. All Bob needs to do now is fly it in the dark so the lights can be seen…

Here is the latest of many that 1066 has fiddled won in the Big Raffle, an Evans Volksplane VP-1 from HobbyKing.This balsa built-up electric monoplane has a detailed instrument panel inside an open cockpit, pilot bust, and control surfaces with large counterbalances built in. Here’s what Hobbyking has to say about it: Enjoy simple, traditional flying that has lasted generations. The Volksplane design was first created by aeronautical engineer William Evans in 1968 and has delighted hobbyists ever since. This yellow and grey US Version is made of lightweight balsa and plywood, featuring a printed PVC covering. The 62.9” span Volksplane is an almost ready to fly kit from VQ models and some assembly is required, although the parts count is low. 1066 has fitted an NTM 4250 650Kv PropDrive motor which swings a 13×6 prop, and uses a 4 cell lipo via an 80A esc with a separate BEC. He said it was horrible on the first flight but then realised what he’d done. To set the control throws he had simply copied over the settings of another model on the transmitter without thinking too much. The model he had copied was one of his 3D machines so he was flying with 90% expo on the ailerons, about 60% too much for the Volksplane! Once he’d sorted out the settings properly it was much nicer to fly as you can see in the video.

Earlier I talked about Page Boy’s Dawn Flyer but he also had a maiden flight with his FMS Edge 540. He actually brought the Edge up to the patch in July 2016 but didn’t fly it and didn’t bring it out again until now. The 1320mm span model is made from EPO foam and weighs 1.7kg with its 4 cell Turnigy NanoTech 2650mAh battery. It comes ready fitted with an FMS3948-750Kv motor, a Turnigy Plush 60A esc, and 4 x 17g metal geared digital servos. Unusually it all comes with a 3 bladed 13×5 prop and matching spinner. The Edge flew perfectly well as expected but it seemed to lack the power you’d expect (and need) for the all the usual 3D manoeuvres.I’ve watched the FMS marketing video of the Edge and it has loads of power, certainly more than Page Boy’s. As it comes with all the powertrain already fitted the only think we could think of was that Page Boy’s batteries aren’t up to the job. Has anyone got any high C rated 4 cell packs that he could try?

Page Boy also had a couple of flights with his Dynam Hurricane in July. He hasn’t flown it for a while and in the meantime has replaced the retracts with some much sturdier metal ones from HobbyKing. They worked perfectly and I shot some video of the flights which I’ll include next month.

The latest club member, Mike Critchley, has been practising hard for his BMFA ‘A’ cert since joining PAM.  Mike is a member of MVSA and is used to flying gliders but wants to fly power models so he’s bought a Wot-4 Foam-E.The Wot-4 is probably the perfect trainer for him but he also has an electric Multiplex Easy Glider that he’s been flying at the field, obviously a man of great taste and impeccable style!I’ve been impressed by Mike’s commitment, in July he had flight after flight just doing figure eights in preparation for the test. He’s gained second place in the Climb ‘n’ Glide comp for ‘A’ cert holders even before taking the test. But on Sunday 22nd July he took his test, even though it was probably the busiest Sunday this year with lots of pilots watching, and passed with flying colours. Dougal conducted the test and once Mike had passed the flying section Dougal gave him a good grilling on the questions. All went well and Mike is now the proud holder of his ‘A’ cert.

We welcomed two more new members in July, Matt Takhar and Niki Weatherley. Both already have their BMFA ‘B’ certs but hadn’t flown for a few years before joining us at the patch a couple of times during July. To get back into flying they both bought Wot-4 Foamies and Max Thrust Lightnings but they are now down to one of each! They have joined up and they will be a welcome addition to our membership.

If you read the last Patch News you’ll have seen the Chris P Bacon carelessly ‘lost’ two models within the space of a few days. Well now he has a replacement, a Ripmax Bolero, a model that is billed as ‘a high performance fun-fly aircraft with huge control surfaces for 3D flight.’ Apparently it was designed by some bloke called Alan Wood. Let’s hope it’s not our very own Woody earning a bit of extra dosh on the side! The model comes as an ARTF so the purchaser has to supply their own powertrain, servos etc. The Bolero is 59” span and the finished weight should be around 3080g (6.8lbs). Chris P has used the same motor etc. that had powered his Wots Wot including the 5 cell lipo. He asked me to do the test flight and the Bolero was good, it flew just as it should although Chris P had sensibly set the control throws towards the low end of the scale so it wasn’t too lively. After some minor trimming I passed the transmitter to Chris P but he very quickly passed it back to me and he’s now practising more with his Cougar 2000 before trying the Bolero again!

The last new model I spotted in July was an EDF Hawk belonging to Norwegian Nick. I thought it was the same as the one that Dougal flies but looking at the HobbyKing website I think they are different models. Dougal’s is a 950mm span T-45 Goshawk with a 64mm dia fan but Nick’s is a 990mm span BAE Hawk with a 70mm dia fan. Oddly the BAE Hawk is described as Red Arrows but it comes with a US Navy colour scheme! The other major difference is that Dougal’s flies extremely well and Nick’s doesn’t…well not yet anyway.Dougal’s Goshawk comes as a Plug ‘n’ Fly so the motor and fan are already installed. Nick’s model came with a fan supplied but he has fitted a ChangeSun 10 bladed fan, not sure if he has the recommended motor or not. Both models are designed for 3 cell batteries but Nick’s just doesn’t seem to have enough power to fly and is going to need 4 cells. I think the high blade count of the fan means it needs more power to spin at an efficient speed. But the aborted attempt at flight did virtually no damage so hopefully it will fly properly very soon.

On Thursday 12th July we held the annual chuck glider competition at Buriton before the usual club meeting. It’s always a popular event and there were 11 entries this year. One entrant was a PAM member from around 35 years ago, Peter Mason. I remember Peter but I doubt any other club members knew him other than Don of course. Peter was an art teacher and he designed and painted the club logo featuring a Marsh Harrier. He brought the original along with him and presented it to Dougal for the club, a nice thing to do I thought.It was great to see Peter again although sadly he is struggling with Parkinson’s Disease and is far from well. But he had a valiant attempt at the comp with a couple of chuck gliders that presumably were getting on for 40 years old. Peter is coming to the club meeting on 9th August when he will run a quiz on general aviation for us all, please try and make the meeting. Back to the chuck glider comp now, the first three places were taken by Colin Cowplain, Percy Vears, and Tony Neil. Thanks to Dwayne Pipe for running the comp and recording all the times. Kryten was on hand to take photos, here’s a selection: Catapult King is named because of his model launching prowess but it didn’t seem to go quite right with his chuck gliders. I think it was down to lack of trimming rather than poor throwing but he was unimpressed with their performance and decided to stamp on them! Perhaps we need to rename him Wrecker Richard…Speaking of comps, don’t forget to have a go at the ongoing fun-fly comps that run all year. There are various tasks to try and there are classes for A cert and B cert holders to give everyone a chance. Full details of the tasks and the latest scores can be found on the Competition page of the website. I can’t help noticing that at the moment in the Max Glide event the top 3 scores for the A cert holders all beat my B cert time. Hmmm…must try harder!

Video time now:

This month’s ‘joke’ is actually a true tale, a conversation between Dougal and myself. Whilst flying alongside each other one day Dougal’s transmitter suddenly started making intermittent beeping noises:

“Why’s your transmitter beeping, is it the low transmitter battery warning?”

“Dunno, I’d better land and check it out.”

A few minutes later he returned and took off again.

“So what was the beeping?”

“Well there’s this knob on the transmitter…”

“I know that…!”  End of conversation.

I must start by apologising for the lateness of this Patch News. I seem to have been away for most of June and only arrived home on 2nd July after being away for the last two weeks of June. Of course this means I haven’t been flying much so I’m relying on information, photos, and video that others have been kind enough to provide, and this edition will undoubtedly be rather shorter than usual. Many thanks to Dougal, Kryten, Dwayne Pipe and all others.

Some of you may remember that last year the mower packed up and it was decided to buy a new one and to keep the original one as a back-up once it had been repaired. Percy Vears has now repaired it and brought it along to check it was working properly. All was good and Bob the Builder & 1066 did a bit of gang mowing.So now we have a back-up mower should one fail. With the new fence in action the condition of the patch has improved dramatically and that has the added bonus that the mower has an easier job to do, less bullock ‘deposits’ and hoof marks to mow over! The patch is looking great at the moment.

The first new model to feature this month is a glider from 1066. It’s a 2.4 metre span ASW-28 that he bought from HobbyKing but he’s chucked the box and instructions with all the info!Apparently the original manufacturer is Volantex and this is from their website: The full-scale ASW 28 is a Standard Class glider with a fifteen metre span built of modern fibre reinforced composites. The manufacturer of the ASW-28 is Alexander Schleicher GmbH & Co. The ‘W’ indicates this is a design of the influential and prolific German designer Gerhard Waibel. Serial production started in 2000. As all Standard Class sailplanes, the ASW-28 does not have flaps or other lift-enhancing devices. It has tall winglets, a retractable undercarriage and a water ballast system. The structure is a complex composite of carbon, aramid and polyethylene fibre reinforced plastic. This permits a light structure with the strength to carry large amounts of water ballast, thus permitting the widest possible range of wing loadings for weak and strong soaring weather.

The Volantex ASW 28 is a sport scale model that does incorporate flaps unlike its full scale counterpart. It comes plug and fly so you just need to complete some final assembly, install your battery, receiver and fly. The airframe is a mix of EPO foam for the wings and tail, with a blow moulded plastic fuselage. This gives a slick finish that is also extremely durable. Great for those less than perfect slope sites. A powerful 4018 850kv brushless outrunner motor rockets the ASW 28 to altitude, then when you throttle down, the propeller folds back for extended soaring. Accessing the battery is easy through the canopy with four small snap locks that keeps the canopy secure.
This Version 2 comes with lots of extra features. The wings come with two spars in each wing to give extra strength during those tight turns and power dives. Installing the wings is now easier with a plastic latch for securing the wings. Inside there is now a bigger plywood tray to make it easier to carry FPV cameras, VTx’s or other electronics. Landings are now a lot easier with the inclusion of landing gear. No more scraping the fuselage.Not sure what VTx’s are, anybody know? Anyway it seems to fly well. 1066 says he’d like a bit more power but then he always does! The wings certainly flex a lot but it looks good in the air and it was definitely a bargain price.

Chris P Bacon had an ‘eventful’ June, he managed to destroy not one but two of his Chris Foss models! The first was his Wot-4, one of the built from wood versions that comes ready for either I/C or electric motors. Chris P’s was electric of course, powered by a Turnigy L5055C 700Kv outrunner and a 4 cell lipo battery.The model took off normally but almost immediately Chris P said he had no control. The model didn’t appear to do much other than continue in the same direction but losing height quickly. The resulting crash was pretty comprehensive and I don’t think it will be repaired. Although the first call was loss of radio it all appeared to be working perfectly after the crash and Chris P is now wondering if it was actually a lipo failure and all he had really lost was motor power. The pack had previously swollen but the cell voltages appeared to be fine and when we checked them again after the crash the voltages still looked normal. But later he wondered if the meter just showed 3 cells at normal voltage and nothing at all on the fourth cell. I’m not sure a duff cell would actually not register at all and anyway I think the model would still have flown on 3 cells although obviously with a quarter less power. Chris P has ditched the pack after the crash so now there’s no way of knowing for sure.

Chris P’s second Fossie failure was with his Wots Wot, that’s the biplane one. The Wots Wot is quite large for a bipe at 50” span and it weighs around 7lbs. It’s all built up construction from balsa and ply, and is designed for a .70-.81 4 stroke glow engine or a 5 cell electric set up with a 5055 700Kv motor. That’s the same motor as Chris P had fitted to his Wot-4 but that used 4 cells. This time the crash had a much simpler explanation, loss of orientation. The model was flying fine but, at a reasonable distance from the patch, Chris P simply lost orientation and the Wots Wot crashed heavily. It’s a shame to lose a model like that but I think it’s fair to say that Chip P never quite mastered it and although I flew it several times I must say that I never felt quite at home with it somehow.

On to more sedate things now, Captain Slow has re-motored his Multiplex Twinstar which was originally built with a pair of 6v Speed 400 brushed motors and flew on an eight cell nimh pack.But the always-with-the-latest-tech Captain Slow wanted to ditch the NiMH batteries and use his lipo packs. He wasn’t convinced that the 6v brushed motors would be able to handle the higher voltage of a 3 cell lipo so to keep up with the latest technology he bought a pair of 12v Speed 400 brushed motors! To be fair (that’s not like me at all) he said that if he had switched to brushless outrunner motors he would have had to change all the wiring within the wings. I’m not sure about that, the latest versions of the Twinstar come with outrunner motors and the speed controllers fit in the nacelles behind the motors so surely you could use the two wire power leads that are already in the wings? No doubt Captain Slow will explain…

Percy Vears took a trip up to Medstead to see Ian at ModellbauUK and bought himself a Max-Thrust Riot. It’s very much a Wot-4 lookalike but is supposed to be better in certain aspects. This is what the website says about it: The Max-Thrust Riot is the perfect all-rounder. With reduced control throws it’s smooth, stable and remarkably easy to fly for the novice or beginner. Increase those throws and the Riot more than lives up to its name thrilling the most ambitious aerobatic pilot. Featuring durable “EPOFLEXY” construction throughout, the superbly moulded airframe is not only very light and stiff, it’s extremely tough too. It’s ideal for operating from “less than perfect” flying strips, resisting hangar rash and those inevitable bumps. And to keep you flying there will be full spares support available.

The Riot is 1400mm span and comes complete with all you need to get it in the air except a receiver and battery. Everything just screws together, no glue required. I haven’t had a go with it yet but I watched Percy flying it and it looks very steady in the air, and it even has lights on the wingtips, Woody must be yearning for one already! 1066 did the first flight and found it to be very aerobatic on full rates but at the moment Percy is flying it on the more sedate low rates.

While I was away Dougal Entendre sent me a couple of reports for Patch News, here’s the first one: Catapult King brought along his F16 (formerly Chris Hard’s). He’d not flown it for a while, and forgot that anything over half throttle is inadvisable, which led to quite a hairy first flight. He kindly let me explore its flight envelope on the second flight – all went well until I tried it inverted, when it went into quite a violent oscillation. I throttled back and pulled out successfully, then tried it again – same result. I flew it around fairly gingerly for the rest of the flight, and landed it without incident. We investigated the all-moving tail and found no problems, but as shown in the photo it transpired that in fact the whole of the rear part of the fuselage (apart from the hatch cover) had almost broken off! We were lucky to get away without a much worse outcome.

Later on in the pits, someone said “Hey! Look at all those flies!” A huge cloud was coming our way, and we quickly realised it was a swarm of bees. We all kept our heads down, and fortunately they passed without incident.

Towards the end of the morning 1066 was aerobatting his Piper Cub (as he does). He pulled out of a manoeuvre inverted over the south field, then appeared to go in quite hard. He stomped off to get it muttering about how that was the end of that, but remarkably came back with it all in one piece, with no sign of any accident! I think he would have flown it again if we hadn’t put the electric fence back up by then.

Dougal’s second report is about his visit to the Horsham club following the cancellation of the show at Sumners Ponds: I had a brilliant time flying at the Horsham club’s field in just about perfect conditions. We parked along the edge of the field under the treeline, which provided some welcome shade. Although the field was covered in grass about 18 inches high, they had mown a track out to a 60m strip in the middle. I must say the facilities were excellent – they had a large shipping container for all the mowing equipment with an en-suite chemical loo, and a generator for recharging batteries if required. Free tea, coffee and biscuits were supplied throughout the day.There was a good variety of models, from gliders, large scale and large 3D planes down to club trainers, and a smattering of helicopters. Flying was very relaxed; in fact general flying was suspended at one point while someone took his ‘A’ test!

I had 5 flights during the day, and my Mini Blitz delta attracted every bit as much attention as the SPAD. In fact, the Horsham club chairman later emailed me to ask for details of the delta, as he thought they might do a club build competition based on it themselves! I counted at least 25 cars and vans at the busiest point, so it was quite well attended. All in all one of my best RC days out, and if they do it next year I will certainly try to get along there again.

Thanks for those reports Dougal.

The last new model I spotted (and was asked to test fly) in June was Bob the Builder’s Durafly SlowPoke.It’s another one from HobbyKing and at 1200mm wingspan is a handy size and uses almost ‘standard’ 2200mAh 3 cell lipo packs. It is a Plug’N’Fly so just needs a receiver and battery. The power is provided by a 3648 700KV motor and 40A ESC and the prop is a 12 x 8. The model comes with large balloon wheels that are perfectly suited to our grass strip. It flies beautifully, handles the wind well, is nicely aerobatic but looks good just stooging around the sky. When I did the first landing I remarked ‘If you can’t land that you can’t land anything’. Bob has tried to prove me wrong a couple of times, it seems to be magnetically attracted to the only fence post we leave in place when we fly! All in all a lovely little model and you can see it in action in this month’s video.

Inspired by the success of Bob the Builder’s Blitz Fu Dougal decided to try this, a Kung-Fun-3:He says it’s just a concept at the moment as he hasn’t finalised the attachment method. I’d be a little concerned about the prop clearance on the Kung Fu myself!

I have a few photos from last month’s club model flying day for you:

We had some lovely summery weather during May, and in particular it was ideal for the first flights of this year’s club models on 6th May. The field remained bullock free for most of the month partly due to the Sustainability Centre using it as the car park for their Green Fayre on 13th May. The fence was left in place that day but switched off just in case some little darling decided to see if the warning notice was genuine. We added red/white striped tape to the top wire to make it more visible in the hope that the visitors wouldn’t drive right through it. They didn’t, and all was well when 1066 went to turn the fence back on in the evening. We are expecting the bullocks to return any day now but we’re ready for them, the fence is armed and dangerous…well switched on anyway. Woody did a ‘hands on’ test of the fence the other day (accidentally) and it certainly gave him a jolt… Oh how we laughed!In the meantime the Friday afternoon mob have been working well rolling and cutting the patch and it’s now it is in excellent condition. Barring any fence problems the patch should just get better and better through the summer.

The highlight of May had to be presenting and flying of the 2018 club models, the Mini Blitzes. The presentation was at the meeting on 3rd May when no less than 13 models were brought along. There are at least 2 others that couldn’t make the meeting so I know of 15 that have been built, a good number from a small club.Most were built more or less to the plan but there were a couple of ‘oddities’. Firstly Dwayne Pipe decided the Mini Blitz was going to be too small and too fast for him so he built a twice size version. Having flown my ‘correct’ size Mini Blitz I have to say I can see his point, mine is very fast and being so tiny it disappears all too quickly. The second model that wasn’t to plan was Bob the Builder’s Blitz Fu. In a brief moment of insanity Bob decided to mount last years’ club model, a Kung Fu, on top of his Mini Blitz. So he ended up with a twin engined (one above the other) biplane, the lower wing being a delta and the upper one a swept forward flying wing. The normal Kung Fu elevons became just ailerons, with the Mini Blitz elevons being just one elevator. What could possibly go wrong?! All the other Mini Blitzes looked to be pretty much standard although Kryten’s was made from Depron and had a Kline-Fogleman stepped wing section (more shades of the Kung Fu). Modelling Clay’s Blitz stood out for being very heavy, I think he’d made it out of modelling clay! The customary judging by all present took place and the winners were: Best Looking Model – Tony Neil and Dan Handley (Page Boy) tied for first place. Least Likely to Fly – Bob Hill (Bob the Builder). Most original design – Bob Hill.

Neither Captain Slow nor Dwayne Pipe could make the official first flight day of 6th May so they both flew theirs the day after the meeting. Dwayne’s just flew away perfectly from the launch with just minor trimming required, all rather boring really! Captain Slow’s was rather hairier and, much like most of the correct size ones, it was fairly fast and disappeared rapidly. After much protesting and shouts of ‘I hate it’ etc. from Captain Slow we let him land to have a coffee and a lie down! But later both I and 1066 flew it and found it was a nice flier with no vices. To be fair to Captain Slow, the Blitzes really do need to have very different colours or markings on the top and bottom surfaces, it’s all too easy to lose orientation with such a small model. Captain Slow’s is almost identical top and bottom and I think that’s a large part of why he hated it!

On Sunday the 6th the weather was perfect for the test flights and 10 of us turned up with our Mini Blitzes. As various ones flew we discovered that very little reflex was needed, much like the Kung Fu’s last year. Modelling Clay’s didn’t get away from the launch, I think it’s going to need a bigger motor to overcome the weight problem.Kryten’s Depron Blitz failed to get away from the launch the first time but after minor tweaking it is now flying well.All the others flew well, some are relatively slow, others, like mine, are scorchingly fast and difficult to keep up with! Orientation is a problem as they disappear so quickly. Although mine flew well I did manage to break it a week or so later but it was soon repaired and flying again. Dougal was good enough to photograph it for me…so kind…The biggest surprise was Bob the Builder’s Blitz Fu, not only did it fly but it actually flew well and was nice to fly. Sadly on a later flight, it lost the battery retaining hatch, closely followed by the battery; the result was inevitable.

This month’s video includes several snippets of the first Mini Blitz flights but they are a bit too small and fast to get much decent quality footage so it’s a bit limited. The video also includes a couple of models that first flew last month, Stanley Knife’s Excalibur and Norwegian Nick’s Sprite, but I forgot to include them in the last video. Some of the video and superb photos this month come from Captain Slow, Catapult King, Dougal Entendre, Gentleman Jim, and Kryten, many thanks chaps. I think it was Kryten who took these lovely shots while I was flying John Warren’s newly repaired (again!) Albatross. Note the trailing rigging wire and the wheel with a tyre hanging off! I always like photos of the buzzards and kites that we often seen when flying. Gentleman Jim snapped this superb one of a buzzard with amazing plumage and Kryten took the one of a kite having a close look at my Ezio glider. As well as all the Blitzes several other new models first flew in May. First up we have Page Boy with his Phoenix 1600 that was a Big Raffle prize last year. We’ve seen several Phoenix 2000s flying at the field but this is the first 1600 as far as I know. It’s basically the same model but with 400mm less wingspan and (I think) a slightly shorter fuselage. The powertrain is the same in both models so the slightly lighter 1600 version has a bit more go and is a bit more aerobatic, but presumably doesn’t glide quite so well. It’s Page Boy’s first electric glider and it will take a bit of time to figure out how to get the best from it but he seemed to enjoy the first flight and had no problems.Next we have Catapult King with his new Altagerra.  When we first saw it several of us oldies said it looked like a control-line stunter and it turns out that’s exactly what it was originally. The Altagerra was a free plan from the Outerzone website and drawn up by someone referred to as Old Pilot so Catapult sends his thanks to both of them. It is a conversion from a 1961 control line stunt plane and Catapult’s is powered by a 2200 3 cell lipo connected via a HobbyKing 40A esc to a Turnigy D2836/8-1100Kv motor fitted with a 10×6 prop. Catapult says he needs to do a power check to see if he can increase the size of the prop as it could do with a little bit more pull. That said its flight characteristics are fine and it will do a loop from level flight. All the throws are wound in quite a lot and have a large amount of expo as it was originally extremely twitchy as you can imagine being a stunt plane with a short fuselage. A quote from the designer Old Pilot: I’m converting the Altagerra, a 1961 control line stunt plane, to a 5 channel R/C electric for a contest build on RC Groups. Had to change the feathers a bit to tame Dutch roll and porpoising, along with the size and location of the ailerons for better roll response…

Wonky Wiltshire has had an EFX Racer for quite a while and flown it lots. It’s pretty quick but when Durafly announced the EFXtra Racer version he couldn’t resist. He first showed up with the new EFXtra Racer back in November last year but he decided not to maiden it in the howling gales present that day.It’s a clipped wing version of the EFX Racer that has an uprated motor and esc, better servos, and ball link connectors. There is more battery space and also more glass fibre and carbon fibre reinforcement.The website says it’s suitable for either 3 or 4 cell batteries, with just a different prop size to suit the cell count you choose. I’m not certain whether Wonky was using 3 or 4 cells but from the way it went I’m guessing 4 cells. Watch it on the video see what you think, if that’s 3 cells I don’t ever want to see it go on 4!

The next one is far from being a new model, in fact it’s pretty old, but Dougal has recently given it an update. It’s an Olympic 100” span glider and Dougal has flown it at the field occasionally over the last couple of years when he has fitted it with a pylon mounted electric motor. It worked well enough but it certainly wasn’t pretty.But in May Dougal decided to bite the bullet so he chopped off the nose and fitted a permanently mounted motor.It looks a lot neater than the pylon mounted one and the model flew well, although the climb rate is rather sedate.

Dougal also flew his large scale Spad XIII a few times during May. I’ve featured the Spad before in Patch News but it’s only had one outing previously so many of you won’t have seen it. The model is an ARTF from Maxford USA and at fifth scale the Spad is 1727mm (68”) span and weighs around 6kgs (13lbs). To power it Dougal chose a Turnigy Aerodrive SK3 – 6364-245kv brushless outrunner motor which swings an 18 x 8 propeller at about 6000rpm. He uses two 5800mAh 4 cell Zippy Compact lipos in series (8 cells) linked to a Robotbirds Pro-80 amp Brushless ESC V4 Opto HV speed controller. He’s fitted a separate high voltage BEC to ensure the radio gets the voltage it requires.There is loads of power available and the lipos still had around 50% capacity remaining after each 7 minute flight so there’s plenty of reserve. Dougal says it’s lovely to fly around and he’s now progressed to doing gentle aerobatics with it, but the landings are taking a little longer to master. A big heavy biplane with inter-plane struts and rigging wires has a lot of drag so it needs to be flown all the way down with some power applied which makes it difficult to touch down on our small patch. But Dougal is getting there, each landing is better than the last and, as you can see on this month’s video, he’s pretty much cracked it now. Assembling a large model at the field is a bit of pain, and then it has to be carried along with all the usual equipment as well as a ‘back up’ model. This is Dougal’s solution:

The video also features another previously featured large model, Norwegian Nick’s gorgeous Citabria Pro that he built from a Balsa USA kit. The model is 2032mm spam (80”), is covered in Solartex and is fitted with Hitec servos. The all up weight is 11lb 9oz so it needs a powerful motor and Nick eventually plumped for a PPPO 5065-380Kv from 4-Max which should provide 1820-2100 watts. He has fitted a YEP 100A speed controller and it is all powered by a 5 cell lipo of 3000mAH capacity. When he flew it previously Nick felt it could do with a little more power so he has fitted a larger prop and it now has more than enough get up and go.As you can see in this month’s video Nick enjoys doing lovely smooth low passes with the model, some very low!

Things don’t always go perfectly for even the best fliers and some tend to get a little over confident at times, especially with older, small, almost throwaway type models. 1066 in particular tends to get a little carried away with low level manoeuvres, and one ‘mad moment in May’ resulted in this:Ouch! 1066 says the Kung Fu is (was?) such a great little flier that it will soon be repaired or replaced.

I was sent an interesting photo by Gorgeous Gary of his Jive that had lost a large section of covering one flight.I think I can see the problem, the name’s a rip off…  Oh stop groaning you lot!

We had a flying visit (literally) one May day when a paraglider overflew the field and landed in the bottom field. It looked as if he had simply come too far downwind from the Mercury slope and was unable to penetrate forward to the slope again. Obviously all models were kept well clear as he drifted across our field, it’s just another occasional hazard for which we need to keep an eye out.

A few Blitz in action photos:

Now it’s time for this month’s video. It’s a bit longer than usual but hopefully you’ll think it’s well worth watching:

This month’s joke doesn’t have an aeronautical link but hopefully Woody will enjoy it:

My friend asked me to help him with his crossword puzzle as he was struggling with 4 across.
“What’s the clue?” I asked.
“Overworked postman,” he said.
“How many letters?”
“Thousands!”

What a difference a month makes, in last month’s Patch News I included photos of several of us flying in a snow storm and exactly a month later I took this one of 1066 knife-edging across the patch in clear blue sky.April wasn’t all like that of course but it was an awful lot better than March and we managed to fly fairly frequently. Much of our time at the field was spent erecting and trying out the new electric fence, and then figuring out the best way of using it. 1066 had put in lots of work sourcing and buying all the necessary bits, making up a thief-proof system, and security etching everything. We thought we had everything sorted out ready for the bullocks…wrong!One day farmer George told Woody the bullocks would be put in the field on the following Monday so we removed the battery to charge it, but when we returned with it on Sunday the bullocks were already there and had wrecked the fence and the patch. The wire was torn to pieces and badly tangled and many posts were broken. Lots more work, and money later saw the fence working again but to say we weren’t happy would be an understatement! We then had to work out a system that would allow us to fly safely whilst still protecting the patch and the pits from the bullocks. We eventually worked out a system that seems to work well, with the pits enclosed in an electrified fenced pen adjoining the patch. Not ideal but workable, and we might refine it further over the next few months.The FAGS (Friday Afternoon Gardening Society) chaps have done a great job of rolling and mowing the patch for all PAM members to enjoy and it’s now in pretty good condition, ready for the serious summer flying. In the meantime the bullocks have gone again (not permanently but at least for a while) but the fence is staying up and live as we now know we can’t rely on the farmer informing us prior to their return.

In the March Patch News I included a photo of a Lancaster doing a low pass over our field on a wintry day. Some of you realised that Patch News was published on April Fools Day…but some didn’t and totally fell for it. The original photo was actually of Mick (Hapless) Harper’s electric powered Lanc. It was taken several years ago (by Stanley Knife I think) on a bright summers’ day and I did a bit of photo editing to make it look suitably wintry.As 1st April was the 100th anniversary of the RAF it seemed appropriate to use a Lancaster for my April Fools caper.

I’ve previously featured Woody’s gorgeous looking Ripmax Easy Street but now he has added an undercarriage to allow proper take-off and landings rather than having to hand launch and belly land the thing. It looks very smart, especially with the spats covering the wheels although I’m not sure they’ll last too long on our rather rough patch. The model takes-off well but it’s very slippery and is not easy to slow up enough for a decent landing on the patch. Practice Woody, more and more practice, that’s all it takes!

Chris P Bacon recently decided that he wanted more power in his Wot-4 as it didn’t seem to have enough oomph to satisfy his need for speed. His Wot-4 is the built up wood construction glow or electric power version and he had originally fitted one of those dirty noisy smelly things, a second-hand SC52 4-stroke. Fortunately he soon saw the light and swapped out the I/C engine for the Ripmax recommended electric motor. But now he’s upped the wattage and fitted a Turnigy L5055C 700Kv outrunner, a motor that’s maximum power is quoted as 1600W! Chris P has fitted a 15×8 prop which I reckon should pull it out of sight vertically with no problem at all.

Stanley Knife bought himself a new toy during April, a Durafly Excalibur. It’s a 63” (1600mm) span V-tail warm-liner electric glider, a model that I’ve had my eye on for a while, I think it looks great.This is what the HobbyKing says about it:

Forged for a King in a distant realm, the legendary Excalibur is here. The most anticipated Durafly release this year, the Excalibur must be flown to be truly appreciated. Innovative design features, such as the cantilever forward swept wing, V-tail tail surfaces, incredibly strong construction and stunning lines.  Just like the legendary sword, Excalibur’s strength is paramount. The engineers at Durafly were given their hardest challenge yet, to design a wing that is ultra-thin but incredibly strong in EPO foam! The wing has carefully positioned carbon fibre reinforcement and pre-tensioned glass fibre strips. The fuselage is feature packed with a square carbon fibre tube and glass fibre strips. The V-tail along with control surfaces are reinforced. All these features combine to make the Excalibur a weapon. Servos are all pre-installed with a whopping 3542 800kv Aerostar brushless outrunner motor up front. 60amp Aerostar brushless speed controller. Two piece removable wing makes assembly fast with wire-free PCB connection between the wing and fuse.  Rule the sky with the Excalibur.

No hype there then! Stanley bought the Plug N Fly version so had little more to do than add his own receiver and a 4s 2200mAh lipo He wasn’t feeling too good on the day and decided to let me test fly the Excalibur. I was impressed, very impressed, it flies beautifully, has loads of power, tracks extremely well and has a very satisfying whistle on low passes! The model is supplied with 13×7 folding prop blades but there are also optional 13×8 ‘Pro’ prop blades available for pilots requiring the maximum performance. It certainly doesn’t need them but it might be fun to try them sometime to see what difference they make.

Stanley Knife popped over to Australia a year or two ago to see ex-PAM member Alan Flux and visited Alan’s local model shop that also runs his club. He came back with a tee shirt that I thought was quite funny and worth sharing: I was rather surprised to receive quite a large box from HobbyKing a couple of weeks back as I didn’t remember ordering anything that would require a box of that size.When I opened it and removed all the padding I found six small boxes, each with a cardboard loop around it.Each box was very posh and, as well as the cardboard loop, had a couple of magnets to hold it closed. Inside each one was foam with a suitable cutout and a nice little cloth bag complete with a drawstring.Inside each bag I found a 3 cell 1300mAh lipo and of course its’ XT60 connector was wrapped in a foam tube!The batteries were Graphene lipos and I can’t help thinking some of the extra cost of them must be down to all that fancy packaging, surely it’s not strictly necessary? I notice that HobbyKing have just started using strong plastic bags rather than boxes for some items which gets over the small item in a large box issue but presumably the plastic bag is less environmentally friendly so I suppose they can’t win!

Still on the subject of batteries, I had an email from Smiffy (Andy Smith) asking if I wanted to buy a hardly used battery and speed controller. Think he’s had a bit of a problem!He didn’t say what had happened but it looks as if the speed controller overheated and that set the lipo on fire.

Norwegian Nick has been AWOL for a while but he returned in April and brought along a little model called Sprite.Nick built it from a free plan in the RCM&E magazine, where it’s described as a micro F3A pattern ship, designed by Tim Hooper. The model is built from balsa and the wings are covered in Solarfilm and fuselage tissued and doped. The motor is a Turnigy 1811 2900kv outrunner which is powered by a couple of 95mAh 2 cell lipos in parallel via a 10amp speed controller. Nick has fitted four 3.5gm servos and the all up weight is just over six ounces.On the day he brought it to the patch Nick was unable to fly as he discovered the motor mounts were loose but it’s all ready to go now and will fly as soon as the weather is suitable.

One more new model appeared in April, a 3D capable 1250mm wingspan SebArt Katana S 30E ARTF. This lovely looking model is the latest from Page Boy. Unfortunately I missed the first flights as I was away on the day but Captain Slow took some photos and video for me. Page Boy has fitted 4 Hitec HS65 metal geared servos and a Turnigy 3542 1000Kv motor connected to a Plush 60A speed controller. This is all powered by a Turnigy 2700mAh 3 cell lipo but using a 13×6 prop he’s only managing to get 4 min flights at the moment. The motor is pulling 600watts which should be more than enough considering the all up weight is just 2.2 pounds.Dougal Entendre did the first take-off and trimmed the model out before handing the transmitter over. It flew very well despite the winds being much stronger than was forecast and it looks as good in the air as it does on the ground. Dougal did the landing in the gusty conditions and Page Boy went away very happy.

We are seeing more and more kites around the field each year, usually out over the valley but sometimes right over the patch. They mostly ignore our models, especially ones under power, but they do appear to see Captain Slow’s Obelix as either a threat or simply something that intrigues them, it’s probably the most ‘bird-like’ of our models.I snapped this shot of four kites and the Obelix (at the top right) but shortly before I took the photo there were five of them in a tight formation, all following the model much more closely.

OK it’s video time:

This month’s tall tale was submitted by Norwegian Nick:

Years ago an old Irish ex-WW2 Spitfire pilot was speaking in a church and reminiscing about his wartime experiences “In 1942” he said ”the situation was really tough. The Germans had a very strong Air Force. I remember one day I was protecting the bombers and suddenly, out of the clouds, these Fokkers appeared.”

There are a few gasps from the parishioners and several of the children began to giggle.

“I looked up and realised that two of the Fokkers were directly above me. I aimed at the first one and shot him down. By then though, the other Fokker was right on my tail.”

At this point several of the elderly ladies of the church were blushing with embarrassment, the girls were giggling and the boys laughing loudly.

The Pastor finally stood up and said ”I think I should point out that “Fokker” was the name of a German-Dutch aircraft company who made many of the planes used by the Germans during the war”.

“Yes that’s true“ said the pilot ”but these Fokkers were flying Messerschmitts.”
