David Ashby - Moderator Posted December 12, 2021 Share Posted December 12, 2021 I'm on a bit of a 'stick and tissue' roll at the moment. Just finished this KK Cadet from an old 'cut out the bits' (they weren't always the good old days) version. Will tow it up next Spring and see what happens.... ? 13 Quote Link to comment Share on other sites More sharing options...
Jonathan M Posted December 12, 2021 Share Posted December 12, 2021 Lovely. But what could happen is that it could launch straight into a thermal and - unless you've got a DT fitted - you'll never see it again! This is exactly what happened the Spring before last to a friend's brand new KK Caprice he'd built as a first ever model. He hadn't bothered to set up the DT just yet as we were only just first helping him sort the CG with very low level launches...! 1 Quote Link to comment Share on other sites More sharing options...

One expects it from time to time. We had a club member who built FF rubber powered models.He lost several. Even got one or two of them back. You live with it and enjoy.

Robin Colbourne Posted December 13, 2021 Share Posted December 13, 2021 Your KK Cadet looks beautiful David. Isn't it strange how after the years of R/C one gets drawn back to the purity of free flight towline glider? 2 Quote Link to comment Share on other sites More sharing options...

Isn't it strange how after the years of R/C one gets drawn back to the purity of free flight towline glider? Thanks Robin. Yes indeed. We have a club indoor session every month and, increasingly, I enjoy the rubber FF far more than steering an R/C ultra micro round in circles. As for the flyaway, I guess it depends how high you tow 'em? I was aiming to stand still and use a winder to haul it up to 20-30ft, no more. Just as these chaps do at 6.52 in this vid'. What could go wrong? ? (it's a great video by the way, well worth a viewing.) 1 Quote Link to comment Share on other sites More sharing options...
Outrunner Posted December 13, 2021 Share Posted December 13, 2021 David your KK Cadet looks beautiful, I hope it flies as good as it looks. A wind in tow is a good idea I've never heard of that method, certainly save running around like a looney. On my shelf I have an unstarted KK Dolphin kit that I acquired a few months ago with lots of lovely print wood, just like the good old days! I intend to fit some micro radio and use my 2.4gHz bang bang transmitter that I built using a Phil Green emulator board, roll on spring.

Peter Miller Posted December 16, 2021 Share Posted December 16, 2021 Test flew my Mercury Matador today in perfect conditions. It uses one of the complete power packages from 4-Max 2212 1000Kv. My Matador weighs 1 lb 10 ounces and it climbs like a homesick angel om 1/2 throttle 5 Quote Link to comment Share on other sites More sharing options...

Keith Evans 3 Posted December 23, 2021 Share Posted December 23, 2021 Hi All I thought you might be interested in what I got up to in September this year. I am well into model planes ✈️ so this year I went one step further, with a lovely present ? from my wife Sarah. I was presented with two videos after the flight, which Sarah edited the 45 minute experience, adding the running commentary and stills. The end result is all her work - all I did was fly the Spitfire. We put the video on YouTube. Below ⬇️ is the link. Hope you enjoy ? it. Merry Christmas, Keith https://youtu.be/tZf9erEjouA 3 Quote Link to comment Share on other sites More sharing options...

leccyflyer Posted December 23, 2021 Share Posted December 23, 2021 I took delivery of my Fiat CR42 at our last flying session and my pal Derek has sent me through some nice static shots of the completed model - with the 3D printed bust of Mussolini's son as a pilot figure, the final added scale details and squadron markings. It will be the spring before I fly this marvellous model myself. 50" span (~1/8th scale), weighs 5lb 4oz, for a wing loading of 18.8 oz/sq ft, Powered by a D3548 motor, 11x5.5" APC-E prop and a 4s1p 3600mah Lipo . 15 Quote Link to comment Share on other sites More sharing options...

Peter Jenkins Posted December 23, 2021 Share Posted December 23, 2021 This is new to me but it was built by a Club mate who had to give up flying. I re-engined it with an OS61FX but that struggled to pull the rather heavy airframe around big manoeuvres. It now has an OS 91FX in it - same crankcase so dead easy upgrade. Still running in the engine so probably quite a bit more power to come. Vertical performance is now much better but will no doubt improve as the engine loosens up. It really needs a new cowl as the pitts silencer it came with required most of the bottom of the cowl removed. There are now so many holes in the top to accommodate 3 different needle valves as well. 8 Quote Link to comment Share on other sites More sharing options...

Tim Eastgate Posted December 30, 2021 Share Posted December 30, 2021 (edited) I hope I'm posting this correctly, I've only posted once or twice before). I recently finished this Magnatilla and had a successful maiden a couple of weeks back. It was a lovely calm day and after only a little bit of trimming the model flew very nicely - it does tend to climb a little under throttle, but it's quite manageable (even for a relative newbie like me). It's an electric set up (4s3300mAh) - so I thought I'd include an image of the battery location - all recommended and supplied by George at 4 max. . 4m Edited December 30, 2021 by Tim Eastgate 13 Quote Link to comment Share on other sites More sharing options...
Peter Miller Posted December 31, 2021 Share Posted December 31, 2021 That is really nice! I especially like the battery installation and the dummy engine. Climbing under power is normal. It has been said that speed is controlled by the elevator and rate of climb with the throttle. If one applies more power the aircraft will climb To go faster you then apply down elevator to keep the nose level.

Martin Harris - Moderator Posted December 31, 2021 Share Posted December 31, 2021 Looks just as good in “the wood” as it does in the photos. Tim’s first build was one of your Ohmens Peter, as part of a mass build project at our club over the winter before Covid struck and he was a fast learner who has got the building bug thanks to it. A gentle progression into a climb with added power is a normal characteristic of most trainer and scale type designs but unsuitable thrust lines can affect this. If pitch change is excessive, the first thing to check is that the downthrust (if any) shown on the plan is correct. You can either correct any error or use a throttle to elevator mix (in most transmitters) to adjust the behaviour. Quote Link to comment Share on other sites More sharing options...

When I was in the process of sorting out the battery location, I was fretting a little about how it might affect the CoG and I discussed this with a club mate who is a very experienced model builder. In essence, his advice was to fit the battery and sort the CoG later - so I did, and by lucky chance it happens to be spot on and I haven't had to add any weight at all :-). Climbing under power feels a little disconcerting to me (as a relative newcomer) as the model is doing something I haven't asked it too, eg applied elevator - although I realise I have asked it to climb by adding power it doesn't feel like a direct input in the same way (if that makes sense). I'm gradually learning too cope with these things and it's definitely better than diving under power. ps The dummy engine was printed by a club mate, as were the decals and the pilot - thanks to both for their help.

Thanks Martin - the climbing under power isn't outrageous, but I think I might have a 'play' with a throttle to elevator mix to see if it can be fixed.

Dragged that information out of long ago memories Peter, Tim has just been spoilt with somebody else's designs in the past (Ohmen + Grumpy Tigercub) with superb manners...although I have heard that there is a quite a range to choose from ? so could be kept busy, then again he could always try "Insanity" for a real challenge, or one of my builds? PS I have experienced a couple of models that pitch down under power up (low slow pass with full up elevator and the hedge looming up) is definitely less pleasurable.

Peter Miller Posted December 31, 2021 Share Posted December 31, 2021 Insanity is a challenge to build but flies very like The Ohmen. This upsets those who hope to see the pilot struggling to fly the thing when it flies just lake a normal model!! Quote Link to comment Share on other sites More sharing options...
