Patch News History

Patch News – April 2024

At last, the weather seems to be improving. It’s certainly still spring like and some days we have had all four seasons in one day but there have been quite a few good flying days. The parking area that was very mucky has dried out a lot and the wood chippings that the farmer laid down for us last month have made the situation very much better. The farmer rolled the whole field (except our patch) while some  of us were flying on 18th March. The driver saw us arriving and kindly rolled our pits area as we were walking down from the car park so we didn’t need to move our stuff out of his way. We were able to fly as usual, just being careful to avoid the tractor on take-off and landing, it was bigger than us! Captain Slow has been diligently looking after the fence batteries and changing them when required with the Woody’s help. Hopefully Captain Slow will be flying with us again soon. We mowed the patch several times in April, and despite the increase in size over the old one it only takes about 45 minutes using both mowers so it’s not too much of a problem. What was a problem was that the older mower decided it had mown enough and died.

We have had a few problems with it before which we’ve managed to sort out but this time the actual chassis broke. After a quick committee discussion it was decided to purchase a replacement, another of the same type as the newer mower which seems to do a good job. Mowing a field is asking rather a lot of any domestic mower so the old one hasn’t done us too badly. We also decided to buy a second storage box as we don’t want our shiny new mower left out in all weathers. The chosen new box is bright orange so we’ll need to paint it black but by the time you read this both the mower and the storage box should be in use.

Now look, I have no way of knowing how many people read Patch News each month and I don’t know how much attention readers pay to what they read. But I do know that not one person has queried my report in the last Patch News which was published on 1st April of a Lancaster circling low over the field. There were several pointers to it being an April Fool, not least of which that WE were amazed to see it. So who else saw it with me? The report went on to say that the sighting was on the FIRST of the month, that the pilot was too ALOOF to respond to our waving, and that I took the photo on the FOURTH pass. Lastly, in the photo I included it’s easy to see that it has two-bladed propellors. The plane is in fact ex-club member Mick Harper’s electric powered model, taken several years ago.

Several new models arrived at the patch and were successfully flown in April and I’ll begin with Mini-Mike’s Max Thrust Aggressor. Mini-Mike already owns an Extreme Aggressor which is the EDF version using the same fuselage as the glider Aggressor but with a streamlined 1.2m wing and the addition of a pylon mounted ducted fan unit on top. The one he bought this month is not actually a new model, Mini-Mike spotted it for sale on Facebook Marketplace for £90 and snapped it up. I reckon it was real bargain at that price as it looks as good as new to me and apparently the seller said he’d only flown it a couple of times. Another plus is that it’s the Thermic version which is the same as the Sport one but also has a removeable 500mm wing centre section that takes the wingspan up to 2m. When Mike flew it he was using it without the extension piece in place so it was 1.5m span. Several PAM members fly Aggressor Sports and they are really good all-rounders, they will fly in pretty much any wind condition and will either float around fairly gently or do all the aerobatics you want in true hotliner fashion. Well more warm liner but good anyway. Chas also has the Thermic version but I can’t remember if he usually flies his with or without the extension in place. Mike’s first flight was uneventful, it flew just like the all the others. I did say to him I thought it looked awful but I’d take it off his hands for £95 but he turned down my generous offer! You can see some of the first flight in this month’s video.

1066 also spent some of his hard earned(?) cash this month and I have to admit that I was slightly bemused when he told me he’d bought a Brio, had he suddenly got into toy trains? So I was somewhat relieved to find out later that what he’d actually bought was an ARTF E-flite Brio 10 when he was on a recent excursion to the Modellbau UK shop in Medstead. It’s 1040mm (40.9”) wingspan, 1015mm (40.0”) long and weighs around 965g with a 3 cell 2200mAh lipo battery. The Brio was discontinued by E-flite many years ago so the one at Modellbau was obviously old stock but, as a sweetener, they included a 1000kv motor and a 40A speed controller in the deal. They didn’t include any servos so 1066 had to supply his own. The heat-shrink film was a bit wrinkled on one wingtip but otherwise it was fine. When he tried to reshrink the film 1066 found that he’d made it worse rather than better so is unsure what the film is but it looks fine to me anyway. For the first flight 1066 fitted a 10×5 prop but the Brio was underpowered so he switched to an 11×8 and that is perfect. I haven’t been able to dig out much information online about the Brio 10 but did find this: If anybody knows what precision feels like, 3-time World Champion and 2-time US Champion Quique Somenzini certainly does. And he has poured all this experience into the design of the Brio 10, a 10-size replica that even flies the same as the F3A plane he used to win the 2005 US Nats. At the heart of its performance is a low aspect ratio wing that moves the center of lift closer to the fuselage. The result is an electric pattern plane with outstanding roll rates and a locked-in feel that will give you the confidence to fly artistic aerobatics with absolute precision. So the design has a good pedigree and 1066 reckons it’s really nice to fly, the knife-edge performance being especially good as there’s no coupling between the rudder and other surfaces so there’s no need to correct with ailerons or elevator. Judge for yourself, one of the April flights in is in this month’s video.

We hadn’t seen much of young Charlie for a few months but he did make it to the patch in April when he flew both his Durafly Excalibur and his tiny Volantex Spitfire. Despite not having flown for a while Charlie had no problems, he didn’t seem at all rusty…kids eh, pah! Part of the reason for his absence is that he’s been spending some of his time getting into full-size gliding at Lasham. His mum Nadine sent me some excellent photos and wrote about his experiences for us: Charlie was lucky enough to get a Trial Flight at Lasham Gliding as a Birthday present last year and he had his first flight in a glider in October. Then he had a month’s free membership, but due to the weather at the end of the year they were kind enough to extend it, allowing him four sessions until the end of the year. During these flights, Charlie was able to take the controls for the take-off which is done with a winch launch and do most of the gliding on his own with the instructor taking back the controls for the landings. Above: That’s a Schleicher ASK13 for initial training.

Below: For Charlie’s more advanced training he’s now progressed to an ASK21B. At the beginning of the year Charlie joined Lasham Gliding as a Youth member and has now had over 20 flights and on the last visit was trusted to land the glider himself. Thanks for that Nadine, it’s good to hear about Charlie’s exploits away from the patch. Well done Charlie, most full-size pilots say it’s easier than flying models so you’ll do well!

Bob the Builder bought himself a new model in April, an XFly Tasman that he got from the Kings Lynn Model Shop. The Tasman is an all-foam model that comes complete, ready fitted with a 3536 900kv motor, 40A speed controller, and six 9g digital servos. This is what the website says this about it: The XFly 1500mm (59.1”) Tasman is a STOL-capable, high-wing airplane featuring sporty flight and aerobatic 3D performance. The Tasman’s impressive flight characteristics and large air-filled shock-absorbing tires make short take-offs and aggressive landings on any type of surface easy. The 4S-compatible brushless motor, 40A ESC, 2-blade propeller and a 4S Lipo battery proved to be the optimum setup for power and duration, allowing the plane to hover, roll, loop and fly inverted easily, which makes it highly recommended as an advanced trainer. Factory-installed LED navigation lights, plus operational flaps, are functional scale features that take your experience to another level. The Tasman comes equipped with a latch-type top hatch to fit 4S 2200-3300mah batteries for a wide range in performance and flight times. Personally I think it’s a very attractive model which should be ideal for flying off our sometimes less than perfect grass patch. The fuselage is massive so there’s absolutely loads of space for large batteries and with big wheels it’s not going to struggle getting off the grass. Sadly the first flight didn’t go to plan and repairs are now underway. I happened to be filming at the time so I captured the crash and Bob has said he’s happy for me to include it in this month’s video. Bob explains what he thinks went wrong here: Having lost my trusty WOT4 I needed a new easy to fly go-to model for all conditions. The Xfly Tasman seemed to fit the bill. Good in all wind and terrain conditions. Also very trainer like, i.e. easy to fly, especially with a good working gyro. I need all the help I can get at my age. Well that was the plan anyway. All pre-flight checks seemed to be OK. First flight easy take off then suddenly full left aileron followed by the inevitable crash! What the hell happened? Here is a lesson for anybody planning to use gyros. I think the only way it would have banged full left ailerons on would be if it thought it was inverted and tried to correct itself. Setting up these gyros is quite complicated and as careful as I was I still made the mistake of not doing a re-calibration when installed in a new model. The receiver was installed the other way up in the previous model but I had changed the orientation on the transmitter for the Tasman and it was showing as the correct way up and everything appeared to be testing OK. Although the crash damage was quite extensive it is fairly clean breaks so it should be back in the air soon complete with a simple non gyro receiver. It was a great shame to see the Tasman crash, especially on the first flight, but I look forward to the next flight when I’m sure it will perform well.

On the subject of repairs, young Leo broke the ABS moulded fuselage of his Volantex Phoenix electric glider recently. Leo had asked Dougal Entendre to take the Phoenix up and trim it for him but when Dougal gave Leo the transmitter back Leo was looking at MacFly’s Phoenix which was in the air at the same time and the inevitable happened. This is what Leo said: You can’t get a new fuzz without buying the whole plane again so I decided to fix mine. It took me about 2 weeks of on-off work to custom make new battery mounting racks and to fix the cracks with epoxy and fibreglass. The hardest part was doing the wing bit on the fuzz because there was a big crack along it and there was less then 2 inch’s of finger space to use. But I’m happy with the result and it flies well. Well done Leo, you’ve made a good job of it. ABS isn’t the easiest to repair but the Phoenix is now pretty much as good as new and, as you’ll see in the video, it’s back flying again.

Here are a few more of Kryten’s excellent action shots that he took for us last month:

Video time now this month with footage taken by me, MacFly, and Dougal Entendre. 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

Shortly after VE day, 8 May 1945, an Avro Anson pilot was instructed to fly some high ranking officials, including ‘shinies’ of brigadier rank and above, to an airfield in Berlin. He was flying from England, and as fuel was limited to the exact gallon, he made a careful note of the fuel required. In this case it required almost full tanks to get there and would allow for a straight in approach when they reached the airfield. So, flight planned, he checked the weather report, which indicated slight chance of fog, and set off for Berlin.

To conserve fuel, careful engine management was vital. Upon approaching the border of Germany he radioed to the airfield met office and asked for the weather report. The operator indicated he was covering for the officer in charge, and read out the airfield weather report. As the pilot approached Berlin airspace he could see fog but no airfield. So he descended with caution and asked the controller to talk him in. He wound down the landing gear, deployed landing flaps, and heard the ATC’s last comment, ‘good luck’.

The instructions however, were not precise enough and he spotted the airfield lights away at 10 o’clock position. Realising the fuel gauges needles were all on empty he slammed the throttle and pulled the Anson round hard. Under the sudden change of direction he heard the groans from the Anson’s airframe, and also from the ‘shinies’ in the back. The aircraft was pulled around – no time to line up – just plant the wheels and line up after. About ten feet before the wheels touched down both the engines cut out.

In his pilot’s log he wrote: ‘Engines cut on approach – shinies spilled soup on uniforms – had to be towed off runway…”

As soon the aircraft halted, the pilot and all the shinies stormed off to the met office, to interrogate the officer in charge. What they found was an erk covering, who had no knowledge of met operations, and who hadn’t even looked out of the window to warn aircraft of the fog, he was simply reading the weather report from the local newspaper.

The moral of the tale: Aways look out the window when reporting the local weather – never use the Berlin Times printed the day before.

Patch News – March 2024

It’s April already and we’re rushing towards those lovely balmy summer days that are ideal for model flying…well hopefully anyway. March wasn’t too bad at all, as expected for this time of year there was a mixture of good and bad weather but some of the days were just about perfect for us and we had some good turnouts at the field. A few of us flew on 3rd March which was a glorious calm day but there was mist laying in the valleys and we needed to be careful as it sometimes blew up across the field. These two photos were taken about fifteen minutes apart, the first one with my Riot ready to take-off, I’m glad I waited! It would probably have been a great morning for FPV flying with some excellent opportunities for a bit of cloud hopping but sadly I hadn’t taken my FPV plane with me.
Never mind there were some lovely views from our field especially towards Butser hill.

I mentioned last month that the parking area was extremely muddy and was causing a few problems with people getting stuck as well as being very mucky underfoot. Chairman Gordon Bennett said he’d have a word with the farmer to see if anything could be done and right on cue Olly (or was it Will?) visited us at the patch to see how we were getting on. When we mentioned the parking area he said they had lots of wood chippings that they could put down for us. Sure enough a few days later one of the farm hands brought three large trailer loads of chippings up and spread them over the worst areas for us.
It’s not perfect, some hard-core would have been even better, but the wood chips have improved it no end and things should get much better as the weather improves.

One midweek morning early in the month Gordon, Woody, and I turned up hoping to fly but there was a strong easterly wind blowing and some of the MVSA (Meon Valley Soaring Association) members were flying. The farmer had asked them to park in ‘our’ newly wood chipped area as their usual place further along the track was waterlogged. Rather than fly from their usual slope they were using the one much closer to us, pretty much straight in front of the masts but well forward. We didn’t fly as the wind was so strong but had we chosen to they wouldn’t have been a problem, they were still well out of our way. We spent some time chatting to the MVSA guys and then made use of our time by mowing the patch. It was good to chat to some fellow aviation enthusiasts, the ones we spoke to were all very friendly and weren’t at all bothered that our new field is much closer to them than before.

I managed to have few FPV flights later in the month and had the on-board video camera running as usual. There wasn’t anything special to include in this month’s video but here are some stills taken from the videos. We flew on Saturday 30th March rather than the Sunday as the weather looked better and found that the metal detectorists of the Hayling Detect club were out in force. There were so many cars present that some of them had to park in the top of our field, as did we, but that was fine and didn’t cause any problems.

The gap between the trees that we sometimes fly through when landing looks pretty big on FPV, much wider than it seems when landing normally. That’s not to say I won’t hit them!

Basher Bob (Bob the Builder) shot past me rather too close for comfort during one flight!

And Dougal Entendre had a similar ‘moment’ with Page Boy’s Wasp pylon racer!

1066 flew a new (to him) model at the end of the month, a Visionaire that he’d bought from Rod Ashton. I’m not sure if Rod had bought it new or had even ever flown it, maybe he also bought it second-hand and sold it on. According to 1066 is was a bit tatty when he got it so he tried touching up the paint in places but it all went a bit wrong. I think he must mean the black on the canopy and in front of the cockpit but it doesn’t look too bad to me. I asked for info on the Visionaire and 1066 said it’s all stock apart from coming without a receiver. From new the plane comes with an AR636A six channel Spektrum receiver that has a built stabiliser, this is how Spektrum describe it: SAFE (Sensor Assisted Flight Envelope) technology is a revolutionary electronic flight envelope protection system that delivers a virtual safety net. Anytime you need to instantly recover back to level flight, just press the Panic Recovery Mode button or switch on your transmitter. Several club members have models with the SAFE system and it generally seems to work well but as this one came without a receiver 1066 will have to rely on flying it properly himself.
The Visionaire has a wingspan of 1143mm (43”) and is made of foam with carbon reinforcements in the structural areas. The brushless motor is a BL 10 1250KV which is linked to a 40-Amp Lite Pro Switch-Mode BEC Brushless ESC and spins a 12×4 propeller. The model comes ready fitted with four 13g servos which are high speed digitals and the recommended battery is a three cell 2200mAh lipo. The Visionaire was discontinued a few years as was the Night Visionaire that came with a High-intensity internal LED lighting system already installed. I’ve been searching the net for information on the Visionaire and it appears that it was originally a Parkzone model and E-flite only sold the Night Visionaire. I think Parkzone and E-flite are both names that are owned by Horizon Hobby and they’ve now stopped using the Parkzone name, just using E-flite for all their models.

To confuse things even more I have founds loads of photos of both Visionaires and Night Visionaires and not one of them has the same colour scheme as 1066’s model. Enough of that, all you really want to know is how does it fly? Well at the time of writing 1066 has only given it one outing but it looked very good to me. It appeared to do everything the usual 3D planes do but it seemed to be especially good at doing things slowly. Maybe that will mean it’s not so good on the windier days, we’ll have to wait and see. But in the meantime take a look at this month’s video where you can see it in action.

On the 1st of the month we were amazed to see an Avro Lancaster approaching the field, very low. We weren’t sure what it was doing, possibly using the radar mast on Butser to line up for a Goodwood approach. We all waved like mad but saw no response from the pilot although I think he must have seen us, maybe he was simply too aloof to bother with us. It circled round several times and on the fourth pass I snapped this rather blurry shot.

 

With a lack of new models being flown in March I’ll have to resort to writing about some that I’ve featured before. We’ve seen very little of Page Boy recently, he was lured away to another club for a while but he soon realised they weren’t nearly as insulting fun as us at PAM so he re-joined us last year. He’s been busy with life in general and hardly managed to fly at all last year, just once in August I believe, and he took the winter off, couldn’t cope with the cold apparently, wimp! But in March he re-emerged from hibernation and gently eased himself back into flying with a pylon racer, his Wasp E2K. Despite choosing Gordon Bennett to chuck the Wasp the flight went well and he soon remembered how to fly.
1066 thought there was a serious problem as the motor only seemed to run at full power for a couple of seconds or so before cutting back to around half power. But there was nothing wrong 1066, it’s called ‘throttling back’, it’s controlled by the left hand stick!
By the end of the morning Page Boy had had several flights with the Wasp, the only problem being that despite our new field having a patch over twice the size of the previous one he couldn’t hit it! Never mind, it’s good to have you back Page Boy.

In the February Patch News I wrote about Mini-Mike’s marvellous Mirus, a design that was first kitted back in the early eighties for IC engines (how quaint, remember those?) but of course Mini-Mike has built his to be powered by a lovely brushless electric motor.
He is using the same power set-up as Page Boy’s Wasp E2K, a Thumper 3536 1500Kv powered by a three cell 2200mAh lipo but rather strangely whereas Page Boy’s Wasp pulls 855w the Mirus is only pulling 615w. I’m not sure why there would be such a big difference and can only think it’s down to the batteries, maybe Mini Mike’s lipos have a lower C rating or are simply older and have degraded. I notice that the Mirus has a 50A speed controller against the Wasp’s 80A but I would have thought 50A would be more than enough. The only other thing could be the propeller, both models are using the same size but possibly not the same make, that can make quite a difference to the current draw.
Even though it has less power than the Wasp the Mirus flew very nicely, plenty fast enough for the first few flights when Mini-Mike was getting used it and trimming it to fly as he likes. It’s slower than the Wasp but it’s a delta not a pylon racer so it’s bound to be slower, they are designed for different things. I thought it looked great in the air and 1066 was right back in reminiscing mode as he watched it. It’s in this month’s video so take a look.

Another model to re-emerge in March after a winter break was Woody’s Splot.
When the Splot first appeared last year it had a few problems and it took a while to work out that there was a wire chaffing inside the transmitter that was causing the rudder to move when the throttle was opened; that made for interesting take-offs! Having sorted that out things were much improved but flying it in early March Woody found the Splot still had a tendency to pull to the left if the throttle was opened too quickly.
This was diagnosed as a lack of side-thrust so Woody added some washers behind the motor mounts to introduce some right thrust and bingo, the problem was solved.

Having several good days of weather meant it was possible for Kryten to take some decent shots of our planes in the air so here’s a selection of some of his excellent action photos:

Video time now this month with footage taken by me, MacFly, and Dougal Entendre. Please watch the video full screen, it’s so much better with small models flying around:

A few years ago at our Air Traffic Centre we received an early warning that an undisclosed number of US Air Force B2 Bombers would be crossing our FIR [Flight Information Region] at a particular time on a particular day.
They would check in with us as they entered our airspace and check out again as they left. We were told the call sign to expect, and, as the route was known, it was logical to assume that they would contact us at a certain time and at a certain place.
Being the then famous new ‘Stealth’ bombers we would know little about it but they would pay us the courtesy of letting us know when they were there.
Eric, a very capable controller with a keen sense of humour was on position, and heard, “UAE Area, this is USAFB2. This is a courtesy call advising that we are about to enter your airspace.”
Eric replied, “USAFB2, welcome to UAE Airspace, we have you on radar 200 miles out over LOTUS, hope you enjoy your visit.”
Without thinking the Stealth Bomber replied, “Thank you UAE, it a pleasure to be… Wait…what?  You’ve got us on radar? 200 miles out? You must be kiddin’ me?”
“That’s affirmative USAFB2,” said Eric, “I’m kiddin’ you. Enjoy your visit.”

Patch News – February 2024

It’s spring, hurrah! Well it is according to the meteorological calendar anyway which says spring starts on 1st March although the astronomical spring apparently begins around 21st March Why am I mentioning this? In the vain hope that we see a change from what has been a very wet February, one of the wettest Februarys on record I believe. As well as limiting our flying somewhat the rain has made the parking area at the new site very muddy and the regulars fliers have been moaning about their filthy cars and their struggles not to make the inside as muddy as the outside. Chairman Gordon Bennett is going to have a word with the farmers to see if something can be done to improve the parking area but the situation should improve once the weather becomes more amenable .

Members did manage some flying in February and apart from the muddy parking area everything has been going well at the new site, the pilots are getting used to the different layout and necessary landing approach. The much larger patch is a real bonus and, as Gordon pointed out at the AGM, when landing on the previous 30m diameter patch you only actually got 30m if the model was exactly on the centreline. On the new 40m x 30m patch the absolute shortest run is 30m and diagonally corner to corner it’s actually 50m.
The small trees to the east of the patch don’t pose much of a hazard on landing, there are gaps between them so it’s easy enough to fly over or between them. On the old patch we got used to trying to land on the first few feet of the circle as the run was so short but now we can come over the trees at a reasonable height and then drop down to land in the middle of the patch with plenty of the strip left. The air does seem to get quite bumpy between the trees and the end of the patch so it’s best not to be too low there anyway.

Five members got the mowers out on 28th February and cut the patch. The weather may have been very wet but it’s also been warm enough to make the grass grow a fair bit.

There are sheep in the field at the moment but they haven’t come anywhere near us so far. The farmer has put their feed station close to our pits area so there are a few droppings around but that’s a pretty minor problem and much better than bullocks droppings.

 

I went to have a look at our old field the other day and, as you can see in the photo below, it has obviously been sprayed with something to kill off the grass as it’s now turned yellow. Oddly there is a strip of healthy looking green grass right up through the middle, maybe they simply missed that part but it seems unlikely. The lower field has also been sprayed so presumably the third one has as well but I didn’t drive down the track to look at that one.

The only casualty of the trees so far was a bit of a surprise as it was Dougal Entendre!
To be fair I should explain that he wasn’t on a landing approach at all, he was ‘doing a Dougal’ i.e. a low inverted pass. He had rolled his little MX2 inverted on the downwind leg of the circuit and was on the base leg when he suddenly lost it. I don’t know if Dougal was caught out by a bit of turbulence or if was simply pilot error but the model suddenly decided it wasn’t going to turn onto finals and flew straight into the nearest tree. Fortunately for us (but unfortunately for Dougal) I was filming at the time so you can enjoy the moment in this month’s video! It looks to me as if the MX2 arrived in the slightly turbulent area at too slow a speed but whatever the problem was we all enjoyed the result! Once we’d stopped laughing at his misfortune we helped retrieve the plane. It didn’t seem to suffer much damage when it hit the tree but more occurred during the retrieval process. The trees are Hawthorns, so rather prickly, spikey things which don’t do lightweight foamies any favours but eventually the MX2 was recovered although it looked rather tatty.
So, after many years at our previous field where we had Harper’s Oak (which was named after Mick Harper, an old club chairman who had a bad run in with the tree) we now have ‘Dougal’s Dogwood’, a name that will probably also last for many years unless 1066 manages to hit it when we can give it the more correct name of  ‘Hastings Hawthorn’.

It was good to see Norwegian Nick come and fly a new model at the new field, an SR-71 Blackbird foamie. He’s flown an SR-71 Blackbird foamie before but this is a new version. Nick built his from a plan drawn up by Laddie Mikulasko which is available from Sarik Hobbies. They offer three different deals, you can buy the plan and magazine article for £16, or a laser cut Depron pack for £11, or a short kit containing the plan, the magazine article, and the laser cut pack for £24. This is the description from the Sarik Hobbies website: Designed by Laddie Mikulasko, this is a quick and easy 693 mm span electric profile sport-scale build from the CAD drawn large single sheet plan. All Depron construction with some balsa and spruce strip, and uses an economical BL2212/06 2200KV motor, 40 Amp ESC and 3S 3000 Lipo with a 6″x4″ in. APC-E prop.
At 693mm span and 1270mm long Nick’s model is actually quite large for a foamie. It weighs 500gms and uses three channels, having elevons and throttle but no rudder. Nick has fitted a 2212/06 2200kv motor which swings a 6×4 APC prop as suggested.  He’s using a 30A speed controller and is powering it with a 2200mAh 3 cell lipo battery. The difference between this Blackbird and his previous one is that for this one Nick used genuine Depron as the earlier model was rather lacking torsional stiffness and strength.

To finish the white Depron Nick sprayed the whole model matt black with Rust-Oleum paint from B&Q.  The model flew beautifully, it looks really good in the air and looks to be quite a stable platform unlike some of the foamboard jets that several of us fly. I managed to take some quite good video of the first flight which you can see in this month’s video.
If you fancy building one for yourself Nick is happy to loan out the templates so all you need is to draw round them straight onto a sheet of Depron and get cutting and gluing. At the time of writing Leo has borrowed the templates and I know he’s searching out some Depron so we should see at least one more Blackbird flying soon. No doubt he’ll quickly hand them on to the next in the queue so we could have a squadron of them before long.

Gordon Bennett had some problems with his foamie Acro Wot in February. One day he was flying it at the same time MacFly was flying his Ruckus and Gordon got the models confused and said to MacFly that he’d been flying the wrong model for a few seconds. Then he watched as the Ruckus flew into the ground…only it wasn’t the Ruckus! A sort of double bluff, “I thought I was wrong but I was right all the time” thing. The damage wasn’t too bad, fuselage broken behind the wing, rather bent nose and so on but Gordon repaired it and it looked fine. Next time he flew it the Acro Wot seemed to gradually develop a mind of its own and Gordon moaned a lot about turbulence upsetting it. He got it down in one piece and checked everything over but it seemed alright so he flew it again. But this time it was really bad and he lost control and crashed again, this time breaking off the nose.
Then Gordon discovered that the rudder horn was broken and he decided that was obviously what had been causing the odd flying characteristics. Cursing himself for not spotting it before the crash he got on and repaired the nose and replaced the rudder horn.
Back to the field for another try where Gordon did very thorough checks including a range check and ensuring there were no unintended mixers and everything else he could think of. Content that everything was perfect he took-off and immediately knew something was wrong and landed safely just off the end of the patch. So he asked me to check it out and I found exactly the same, everything looked ok but when I took off I needed a lot of right rudder to hold it straight so I chopped the power and landed just off the strip. Thinking there may be a control mix linked to the throttle we checked it out at full throttle and immediately saw that the stick on trim (decal) on the left wing was peeling back, especially where it was at it’s widest towards the wingtip, which was creating a huge amount of drag. Gordon pulled off the trim and we tried again. This time everything was perfect and the Acro Wot flew just as well as it always had. That was definitely a lesson learned, if something doesn’t feel right make sure there isn’t a piece of stick on trim coming loose.

Mini-Mike has been quite productive in the model room recently and following on from refurbishing his Acro Wot he’s built a Mirus. Some of you will have seen 1066’s Mirus that he’s built in various guises, I think 1066 is harking back to his youth when he used to fly with the Ken Stokes Mirus Display Team. Nostalgia’s not what it used to be…
Back to Mini-Mike, he bought a Mirus 25 kit from NJR Modelling for £89.90, this is what the website says about it: The Mirus was designed in the early ’80’s by the late Ken Stokes as an easy build fast sports model. Since acquiring the design, we have re-engineered the kits to utilise modern CNC and laser cutting technology, which in turn makes for a stronger model that is still very easy to build. It was then, and is now available again in two sizes for I/C engines, a .25 size and a .40 size. We are working on an electric power option for both sizes of model which we hope to be able to release soon.
The Mirus 40 is 39.5” span and the 25 is 37” so there’s not a huge size difference. According to the website they both weigh 3kg but that must be a typo, possibly 3lb for the larger one but certainly not 3kg. Mini-Mike has made his electric powered and has fitted an 8×6 prop on a Tornado Thumper 3536 1500kv motor as used in E2k pylon racing.
He’s mounted the motor on 3mm threaded rod stand-offs from the firewall to bring it to the correct position. The speed controller is 50A and the battery a four cell 2200mAh lipo.All three servos are JX digital metal geared with the two wing mounted ones for the ailerons being slim versions, and the receiver is a Hitec Optima. Mike used Ripmax Aerofilm for the covering and reckons it’s the best one he’s used. It certainly looks good in the photos, I just hope the red with white on both the top and bottom surfaces is different enough to see in the air. There’s more white trim on the underside so it should be alright. So how does it fly? Unfortunately nobody has any idea at the moment as since Mike completed the model the February weather hasn’t been good enough to test fly the Mirus but hopefully he’ll be able to fly it early in March. Watch this space for a flying report.

The photos this month are all taken from videos so not the best quality I’m afraid:

Video time now, this month with content shot by myself, MacFly, and Dougal.
Please watch the video full screen, it’s so much better with small models flying around:

Patch News – January 2024

The format of this Patch News is going to be rather different from usual because there hasn’t been much in the way of new models to talk about but there is a lot of major news about the patch itself. After almost 50 years at Chidden Down we have sadly lost the site. As most club members will know the field we’ve been using was not actually owned by the farmer, Wilson Atkinson Farms Ltd, but was rented (along with two other fields) from the landowner, a situation that had existed since the 1950’s. With permission from both the landowner and the farmer Petersfield Aero Modellers have used the field from around 1975/6 during which time we’ve enjoyed excellent relations with all concerned and have had no problems at all. The permission was originally granted by the late Wilson Atkinson and then control was passed over to his son George who now runs the farm along with his sons Oliver and Will. There has occasionally been talk of the landowner renting to another farm or taking the land back for his own use but it has never come to anything, until now.
Last August the landowner told George he wanted to change the use of the three fields from grassland to arable and would be making a change of use application. George thought permission wouldn’t be granted and the fields would be unsuitable for growing anything other than grass anyway as there’s barely any soil on top of the chalk down so he wasn’t unduly concerned. But in mid-January permission was granted and George was given just two weeks’ notice to vacate the three fields so the landowner could begin preparation for a crop and we were immediately given the same notice. But it’s not all bad news, without delay George offered us an alternative site on land that is owned by Wilson Atkinson Farms themselves and they have said they would very much like us to stay on their land with continued good relations, a situation that also suits us perfectly.

More about the site later, for now it’s on with what else happened in January. The weather during the first half of the month was pretty awful with a series of storms coming through so there wasn’t a lot of flying done but some of the hardy (foolhardy?) members flew in some very cold conditions. Fortunately later in the month the weather improved. On one of the better days there was quite a stiff and chilly breeze but Leo asked Dougal Entendre to test fly a biplane that he had bought from Rod Ashton before Rod joined the club.
Leo doesn’t know what model it is so I can’t give you any details of it at the moment.
He only paid Rod £25 for the model which needed quite a lot of work on the wings and undercarriage and as it had originally been I/C powered Leo had to fit it out with an electric set-up. He had just crashed his Hyperion Edge so Leo fitted the Hyperion motor and speed controller from that into the bipe and is using a three cell lipo although the set-up can take four cells should he decide he needs more power later.
The test flight was a bit of a non-starter as you will see in the video. On the first attempt it looked as if the wind just got under one wing and it took Dougal by surprise with a quick cartwheel. The model looked to be ok so Dougal tried again but… you’ll just have to watch the video, but it made us all laugh. I’ll just say that I’ve not seen a model being sick before!

Another new model that I saw being flown in January was Gordon’s Avios BushMule V2. Gordon has been just a little bit busy (manic!) with the unexpected change of patch and all the paperwork, rules, risk assessments, groundwork, communication, liaising with two other clubs and so on but has managed to write a few words about the BushMule for us:
I got lucky as it was a Hobby King pre-order waiting for the container to arrive so got it for £162 and free delivery. Woody and I both won £100 quid or so on the premium bonds in November so it was a present from Ernie! The package arrived just in time for Christmas Day but I didn’t bother to wrap it up for myself. Super easy to put together but there’s lots of it! Wires all over the place for twin ESC’s, lights and 8 servos so it’s the first time I’ve used cable tie bases in a model to tidy things up. The ESC’s do have reversing but I’ve not wired it as I ran out of channels on the receiver and thought it would only be really useful on water. The 8-channel receiver does allow me to program differential thrust on the twin motors so expect snappy stall-turns and flat spins (no doubt followed by the sound of EPO making rapid contact with terra firma). It’s got a cargo door for dropping miniature Colin Cowplain type parachutists and also a side ‘plug’ door for loading and access. Being a ‘plug’ door means I can do my own ‘Max 9’ re-enactments.
It does look good in the air, as Dougal said, ‘it’s like watching (dodgy) arrivals at Guernsey airport’.   
Sorry Gordon but the dodgy arrivals are mostly to do with the pilot!
Gordon was good enough to let me have a go with his BushMule and unsurprisingly I found that it flies just like mine. He seemed less than impressed when I landed it bang on top of the spot but at least I showed Gordon that the plane can do something that it’s never going to do again! Gordon definitely got a bargain price at just £162, I think I paid £145 for mine about four years ago and it’s now showing as £246 from the HobbyKing UK warehouse. I can’t see much difference between mine and the V2 version other than the colour scheme which I have to admit looks much smarter than mine, but there are apparently several minor improvements as well. Dougal shot some video of Gordon flying his BushMule on a rather grey day and you can see it in this month’s video.

Inspired by watching Mini-Mike’s Acro Wot fly 1066 splashed the cash and bought one, here’s his story: It was in May 1985 that Chris Foss sold his first Acro Wot kit, at the time I had been married for a few years and all available funds were needed for things like furniture, wallpaper, paint etc. During the late seventies, and early eighties a Chris Foss model was a must have, whether it was a slope soarer or power model, who didn’t have a Wot 4?  There is no doubting Mr Foss had an eye for the aesthetics of a toy plane, but he also made sure they were fully sorted, and always had fantastic flying qualities. It is testimony to this that 40 years later his designs are still just as popular today, especially with the introduction of the electric moulded foam ARTF kits. I also think Chris was a very shrewd businessman who always knew he had a great product, so was able to price his kits accordingly, which was a real problem for a recently married, and skint 26 year old me, who always wanted an Acro Wot, but just could not afford one.
Move forward 39 years, and Mini-Mike shows up with his 20 year old Acro, which he had converted to electric, the model flew great, and I was taken straight back to 1985, and remembering how it felt watching club mates fly theirs. Sunday evening followed the normal routine, dinner, settee, computer out, start watching toy plane videos, and I could not get the Acro out of my head, so the now 64 year old me, who has a little more disposable income, took the plunge and ordered a kit £158.00 incl. postage (still too tight to get the deluxe kit). There is a saying that nostalgia isn’t always as good as you remember, and I don’t think the kit is as good as I remember other Foss kits were. Starting with the instructions, these are quite basic, but adequate, however my problem is with the modification sheet! It includes showing the need for plywood fuz doublers, these are advised when using larger engines, but are not supplied! Why? The mod sheet also advises many other changes which are not shown in the main instructions, therefore, if you don’t read the mod sheet first, you run out of some of the stock supplied in the kit!  If they had to add a mod sheet to every kit, why not just amend the instructions? I also think the amount of material in the kit is a bit on the stingy side, there is no fat on this one, therefore you have to be very careful with your cuts. Maybe we have been spoilt by ARTF imports, but the quality of the hardware is also very poor, most of it has been put aside for my next foam board!!! I haven’t done much kit building for many years, but taking into account that I didn’t read the mod sheet first, this one went together quite quickly, that said I had forgotten how many hours you have to invest, far more than just opening a box! I also found myself making some schoolboy errors, the worst of which was applying the wing bandage. So what went wrong?
1. I used polyester resin. 2. I followed the instructions, but the weather was very cold, and after a night in the shed, the resin still hadn’t fully hardened.
To add insult to injury, having mixed too much resin, and not wanting to waste what was left, I painted it all over the inside of the fuselage, and after two more days indoor some areas were still a sticky mess. After crying inconsolable for about 3 hours, logic told me I must have failed to mix the resin properly, so if I brushed hardener on the sticky bits all would be OK, how wrong was I, all it did was make it worse. Aargh! After discussing my pending suicide with Patsie, he advised using super glue on the sticky areas, and as much as it hurts me to say, it worked a treat. Eyes dried, suicide avoided, I was briefly in a much better mood, but this was short lived as I now discovered the resin had soaked through the wing veneer, and dissolved large parts of the foam core, at this point for my own safety, I decided to leave the shed, and avoid the kitchen (too many knives). The pictures show some of the damage, and subsequent repairs.
I know our blog editor likes a bit of technical detail, so for the record the motor is currently a Turnigy G32 770 KV which is swinging a 14×6 propeller.
Because the model is designed for IC there is scope for a large battery, (no point in carrying lead) so I have made room for a 4S 4900mAh 30c lipo pack.
The speed controller is an 80Amp Turnigy. Tests have shown I’m getting 700 Watts @ 60 amps, so plenty of headroom in the speed controller, and the battery should not be over stressed, my only concern is that the G32 is supposed to be the equivalent of 32 glow engine, far too small for a 6lb model, we shall see? At the time of writing the model has not been flown, and as I have never owned one, I am really hoping it flies as well as my imaginary nostalgia is expecting.
Since 1066 kindly wrote the above for us he has had several flights with the Acro Wot and I’m pleased to be able to tell you that it flew a treat.
I’m sure he could squeeze a few more chequers on the underside, he’s just not trying!
No doubt 1066 will be tweaking a few things here and there but basically it’s a good sound model that flies very nicely. You can see the Acro Wot for yourselves in this month’s video.

There were a couple of days that had sunshine and light winds, one of which turned out to be the last flying session at Chidden Down. Several of the committee plus 1066 went along in the morning of Friday 19th to remove the electric fence and associated energiser etc. and were surprised to find the cattle in the field but we had no choice, even the spot had to go.
After lunch, having moved everything to the new site, Gordon Bennett and I went back for the last ever flights at Chidden Down where we were joined by Chas and Bob the Builder. In just a couple of hours the bullocks had managed to cover every inch of the patch in hoof marks and decided it was the best place to stand despite having the whole of the field!
We flew anyway, fortunately the whole field had quite short grass so we ignored the cattle and carried on flying, simply taking off and landing wherever it was clear.

The new site we are now using is on Wether Down, further along the piece of land that is used by MVSA (the Meon Valley Soaring Association) and the Sky Surfing Club who fly hang gliders and paragliders. This offers some challenges, particularly with the Sky Surfers who are the closest to us and whose safety must of course take priority over our flying.
But they don’t use the site very often and don’t intentionally stray along as far as where we will be flying. Gordon has been in regular contact with both clubs and has found them to be very amicable and keen to make the new arrangement work for everyone. The MVSA Chairman and the Safety Officer visited us at the patch while we were flying on Sunday 28th to introduce themselves and have a good discussion about their needs and ours.
The other concern is that our patch is just 250m from the big expensive houses opposite the Sustainability Centre so we must be very careful not to upset them with noisy models.
Gordon has produced the Site Detail drawing above that is included in the new rules that have been emailed to all members. The site looks quite small on the drawing but is in fact much larger than it appears. The red line along the south of the patch must be a strict ‘DO NOT CROSS’ if we are to retain the site. This will make landings more challenging with certain wind directions, we’ve been rather spoilt in the past always being able to land straight into wind. But on the positive side the farmer said a round patch like we had at Chidden created difficulties for them (who knew, we could easily have made it square!) and has agreed to the new patch being 40m by 30m. That means it’s about 70% bigger than before which should make landings easier and help if they need to be crosswind.
To the north are three radio masts and the new rules say no flying within 50m of them. Obviously it’s not easy to judge the distance but several of the committee have had trial flights with someone posted close to the masts and nobody got too close even when deliberately flying closer than felt comfortable, they are just something to be aware of.
The track up to the parking area by the barns is in better condition than the old one, the first part is fairly bumpy but once past the house on the left it’s much smoother and the parking area by the barns is better than before. The committee members who are retired  have been very busy getting everything sorted as far as possible and 1066 was co-opted in to help as he was heavily involved in setting up the electric fence and mower box at the Chidden site. On Wednesday 24th Gordon, Woody, 1066, Chas, Kryten, and myself all answered Gordon’s call to help mow and we cut the new patch area twice. The larger area makes mowing a bit more of a chore but with two mowers running it didn’t take too long. It’ll take a while to get the patch as good as we’re used to but it’s already perfectly useable for most models and by the time you’re reading this we will have cut it again. Latest update: we mowed yet again on Jan 31st so it’s now been cut 5 or 6 times, I’ve lost count!

I can’t stress enough how helpful George, Oliver, and Will have been over the last couple of weeks. They have used their farm equipment to move lots of our equipment including both the mowers and the heavy roller that we thought we might have to abandon. We didn’t think we’d be able to dig out the mower box without destroying it and had more or less resigned ourselves to leaving it where it was and buying a new one. We mentioned this to the farmers one morning and that same evening I received the photo below showing that they’d managed to get it out undamaged and put it in the new field for us, brilliant!

With all the changes going on this month I’ll use some screenshots from my FPV videos to give you an idea of the new site and surrounding area rather than the usual action shots.

Video time now, this month with footage shot by MacFly, Dougal Entendre and me. 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

Did you hear about the budget airline that managed to keep prices very low by only offering late evening flights? They didn’t last long at all before they went out of business.
Apparently word went round that it was a fly by night outfit…
