Colin Leighfield Posted September 24, 2016 Share Posted September 24, 2016 Here's mine Danny. I followed the plan, although I have beefed it up a bit. It looks as if it should work ok. Quote Link to comment Share on other sites More sharing options...
Martin Fane Posted September 24, 2016 Share Posted September 24, 2016 Hi Danny Maybe a bit late but here's mine, I think its the right way round. I actually added a third clip as there was a little movement. Its only had two landings which were greasers by my test pilot buddy, no signs of damage. Looks like you will soon have yours back in the air cheers Martin Edited By Martin Fane on 24/09/2016 19:33:47 Quote Link to comment Share on other sites More sharing options...

Andy Muckley Posted September 24, 2016 Share Posted September 24, 2016 Hi Danny, sorry for the late reply (had to go into work, only just got home ) i am sure i did mine the same as Colin, Terry and Martin . Sorry but it's nice to know your human mate lol. Quote Link to comment Share on other sites More sharing options...
Nigel Day Posted September 24, 2016 Share Posted September 24, 2016 Definitely the Spit Danny. The Mossie's next up on my list so you might just be getting to it at the right time. Quote Link to comment Share on other sites More sharing options...
John Timmis Posted September 24, 2016 Share Posted September 24, 2016 Hi Danny I used some heavy engineering on my undercarriage. No way this is going to break even with. My landings. Cheers John Quote Link to comment Share on other sites More sharing options...

Silver Wolf Posted September 25, 2016 Share Posted September 25, 2016 Late as usual, but here's mine. Certainly not likely to have any problems soon, on the grounds that it will take some time before it actually flies. SW Quote Link to comment Share on other sites More sharing options...
Geoff S Posted September 25, 2016 Share Posted September 25, 2016 I'm not building a Chippie as the scale detail you chaps are including is way above my pay grade But I have been watching with interest. The undercarriage problem being discussed here is strange. Every torsion bar undercarriage I've ever seen uses a hard wood block (often with a groove for the wire as in (say) Peter Miller's Ballerina) and a hole into the block with an extra piece to increase its depth for the anti-rotation arm. The whole is fixed firmly with clamps like the SLEC plastic ones. I just wonder why the designer deviated from normal practice. John Timmis's arrangement is more like it but I'd just have extended the block to take the anti-rotation arm. I'm certainly no designer but I intend to modify the undercarriage on my current build, a foam winged Percival Mew Gull by inserting long hardwood blocks for a torsion bar undercarriage.

Nev Posted September 25, 2016 Share Posted September 25, 2016 Hi all. I haven’t forgotten about the chippy just other things have got in the way recently, nothing serious just the usual stuff. That and a lack of mojo means I haven’t done any kind of modelling recently, building or flying. Looking at the uncovered airframe as we speak however and a large role of solartex above it, so it will be finished this winter, flying in the spring. As much as I would love to get involved in another build, especially a big mossie, I think at 81” it’s a step too far for me but we’ll see. In the mean time I’m going to follow Nigel’s build, I might even get inspired there. First things first though finish the chippy, can’t start another till I’ve finished this one. Nev.

Danny Fenton Posted September 26, 2016 Author Share Posted September 26, 2016 It doesn't look very pretty but I think this will do for now while I try and get another flight to check the flight characteristics. The way this undercarriage is mounted is fine, Remember Dennis Bryant is a designer of the old school and was designing models quite some time ago. With me placing the arm rearwards the load was pulling the piano wire away from the block, now it is being twisted against it. All the torsion armed modesl I have ever had which used a hole in the block worked loose very rapidly Cheers Danny Quote Link to comment Share on other sites More sharing options...
Geoff S Posted September 26, 2016 Share Posted September 26, 2016 I'm sure you're right, Danny. You're far more experienced than I am but the hole in the block method will have to suffice for my quarter scale Mew Gull with its foam wings. I notice the undercarriage on my Ballerina is a bit loose after about 20 landings but I think is unlikely to fail despite the vagaries of my landing style. I have the drawings and cnc parts for a Dennis Bryant 54" SE5a so I'll eventually get to know his methods Geoff Quote Link to comment Share on other sites More sharing options...
Danny Fenton Posted September 26, 2016 Author Share Posted September 26, 2016 Hi Geoff, the hole in the grooved block is very common nowadays, especially with ARTF's and it does work, but I find they loosen over time. I had a 3 Demon from YT and that did take a year or so to become wobbly, but it did become wobbly. I have a feeling the Gangster 52 also used blocks in a foam wing, they might have had a hole to retain the torsion arm. But that was a trike, the loading is different Perhaps Dennis was very focused on weight and using materials everybody would have access to?

Ady Hayward Posted August 22, 2017 Share Posted August 22, 2017 Well folks. Better late than never. Just ordered the plans for a 1/4 scale Chippy. If I can find my ATC Logbook and some colour reference pictures of 8 AEF chipmunks flown from RAF shawbury in the late 60's to 1972 I will build a replica of the first Chippy I flew as an ATC cadet.

Danny Fenton Posted August 22, 2017 Author Share Posted August 22, 2017 Fantastic Ady, which one have you gone for? I have the Dave Womersley, and the Jerry Bates 1/4 scale drawings. And parts for the Bates. It was a contender for the next Masterclass, however the Haker Fury won out instead. Any photographs etc that I can help with just let me know, I have several walkarounds Cheers Danny Quote Link to comment Share on other sites More sharing options...
Ady Hayward Posted August 22, 2017 Share Posted August 22, 2017 Hi Danny, I have ordered the Dave Wormersley one including the parts pack too. I've stalled on the cowl and canopy as I want to be sure of getting the best ones (If you can recommend any particular ones please). The canopies seem to have flat rear glazed panels whereas the T10 had bulged panels. I'm also looking at ways of getting the prop direction changed to left hand if possible. Cheers Adrian PS. I seem to have hit a wall with 8AEF logos of the late 60's era. Any pics will be gratefully received Edited By Ady Hayward on 22/08/2017 11:26:20 Quote Link to comment Share on other sites More sharing options...

Hi Ady which cadet unit were you with ? Quote Link to comment Share on other sites More sharing options...
Danny Fenton Posted August 22, 2017 Author Share Posted August 22, 2017 Hi Adrian, I thought that the cowl on Davids is mainly made from litho plate? there may be a cowl ring for the front, but a fellow of your talent should be able to knock one up I bought the canopy and canopy frame from Phil Clark at Fighteraces. It is for the quarter scale Jerry Bates, but knowing Phil it will be accurate to a 1/4 scale Chipmunk! Should fit anything at 1/4 scale The Bates cowl is pants and quite innacurate..... It cost me a couple of hundred pounds to find out unfortunately.... Good luck and hopefully will get to follow along your build Cheers Danny Quote Link to comment Share on other sites More sharing options...
Ady Hayward Posted August 23, 2017 Share Posted August 23, 2017 Hi Martian, I was with 493 Kings Heath & Moseley Squadron when we lived in the South of Birmingham. I was with them around 6 years up to my joining the RAF as a Halton Brat (Armourer). Danny, I will probably build the cowl from litho plate as I would prefer a scale means of access to the engine. I did ask Fighter Aces about the canopy and was told that the rear panels are flat due to the likelihood of release issues should they have been moulded with the bulged panels. I will probably experiment as I would like to have the canopy able to open and I do like their extra canopy frame moulding.. Cheers Adrian Quote Link to comment Share on other sites More sharing options...
Danny Fenton Posted August 23, 2017 Author Share Posted August 23, 2017 Oh really Adrian? I assumed the fighter aces canopy was bulged. I will go and check mine. I would not have bought it had I known. However it is fairly easy to drop in some bulged sections. Just a pain.CheersDanny Quote Link to comment Share on other sites More sharing options...
