Colin Leighfield Posted March 11, 2018 Share Posted March 11, 2018 As part of my attempted personal flying improvement programme, I have bought the FMS T28 Trojan V4, which has been well-recommended. Supplied very promptly by the helpful chaps at Leeds Models, with three 4S 2900mah Lipos. I could go higher but the advice with the plane is 2600, so I’m sure it will be ok. I have just put it together and got everything working, I just need to set the control throws. It is beautifully moulded and looks to be well thought out. Fingers crossed!

Luther Oswalt Posted March 11, 2018 Share Posted March 11, 2018 Paul, Your Catalina is well done. I have many WWII favorites and this is one of them. Nice to see her! Leo Quote Link to comment Share on other sites More sharing options...
Roo Hawkins Posted March 13, 2018 Share Posted March 13, 2018 this is my second scratch build this last year. not yet had its maiden. it is a nearly 1/3 scale mdm fox and is 4.5 meter span and is 12 kg . the fuz is made by the lost foam method with epoxy/ glass and the wings are foam veneer with carbon and wood spar then the wings are glassed.

David Davis Posted March 13, 2018 Share Posted March 13, 2018 Ok it's not a new model. I built it in 1988 and sold it to my cousin in 2002. He never took up the hobby, though his father, who died when my cousin was a baby, was very keen and taught me how to build model aeroplanes. I bought the model back from him last year and during the last three or four months, I've stripped the fuselage and tailplane, removed the oil-saturated wood, which made excellent fire-lighters, built a new nose to accomodate the LiPos and converted it to electric power. I hope to fly it tomorrow when light winds are forecast. Quote Link to comment Share on other sites More sharing options...
Ron Gray Posted March 13, 2018 Share Posted March 13, 2018 Very nice DD, but it should have a Mills in its nose! Edited By Ron Gray on 13/03/2018 12:58:48 Quote Link to comment Share on other sites More sharing options...
Nigel R Posted March 13, 2018 Share Posted March 13, 2018 Not even slightly new! It was new to me six months ago but this is the first photo I've posted... She's a Precedent Bi Fly 25. Built by my dad about twenty some years ago (while I wasn't flying) for a 25 or 30 two stroke, and sold on to another of his club mates after a few years flying. It was re-sold within the club a few more times, retired, got out, retired (etc) and eventually converted to electric - 400W or so, turning a 10x5, on 4S 2200, gets six minutes of airtime. Fun to fly, but needs hustling along quick sharp like to get the best from it. It's a bit lardy (4 1/4 lb) and lands kind of hot - very intolerant of careless low speed handling!

trebor Posted March 13, 2018 Share Posted March 13, 2018 Very nice, How do your interplane struts secure to the wing ? Ive got a ropy old 40 that just uses self tappers. Quote Link to comment Share on other sites More sharing options...
Nigel R Posted March 13, 2018 Share Posted March 13, 2018 Thanks trebor It's not far off that. The struts have a narrow slot in the end, into the slot goes a servo grommet, and through the grommet goes a self tapper, into a plastic right angle bracket (possibly a cut down control horn). The grommet soaks up all the angles that aren't quite right angles, if you see what I mean. Sounds a bit imprecise, but seems to work OK.

trebor Posted March 13, 2018 Share Posted March 13, 2018 I thought mine had been messed with but it must be standard then Quote Link to comment Share on other sites More sharing options...
Peter Miller Posted March 13, 2018 Share Posted March 13, 2018 I have seen a similar set u in a Biplane kit many years ago. That one had small screw eyes screwed into blocks in the foam wing and the rubber grommet was held to the strut with a nut and bolt/ It worked very well Quote Link to comment Share on other sites More sharing options...

They are perfect in a less than perfect arrival Trebor The bottom wing can actually come away if fitted with nylon bolts And damage is much reduced, then it clicks all back together Quote Link to comment Share on other sites More sharing options...
trebor Posted March 13, 2018 Share Posted March 13, 2018 The last time I saw a plane come down which had nylon bolts they tore the fuselage apart. I think your lucky if the nylon bolts go Quote Link to comment Share on other sites More sharing options...
Andy Horsman Posted March 13, 2018 Share Posted March 13, 2018 Lovely Fox Roo. Makes my 3m one look puny. Must get it back in the air after it's little agrument with terra firma https://www.youtube.com/watch?v=RvuTjeppHvw Quote Link to comment Share on other sites More sharing options...
Nigel R Posted March 13, 2018 Share Posted March 13, 2018 I can confirm Denis' post above. The nylon bolts shear and the struts (which only need to worki in compression) do not hinder the lower wings departure from the situation. The upper wing is bolted on with M4 sized machine screws and will likely need the ply lugs gluing back in, if the ground attempts to forcibly detach the wing. I learned all of this, immediately after learning its dislike of low speed manhandling, during a landing approach. Quote Link to comment Share on other sites More sharing options...
trebor Posted March 13, 2018 Share Posted March 13, 2018 I`ve yet to maiden mine yet as it was an ebay special, what happens at low speed Quote Link to comment Share on other sites More sharing options...
Nigel R Posted March 13, 2018 Share Posted March 13, 2018 The 40 sized one will be as docile as any model you'll find, I think. It has gobs of wing area and turns out lightly loaded even up to around 8lbs. Denis I believe has one of the larger ones. The 25 is simply a heavy model for its size, with all the attendant characteristics thereof. If I scratch built on I think it would come out a pound lighter. But with kit wood... Anyway, keep it moving and its golden. Start jabbing in rudder corrections with the nose held high and no power and it'll drop a wing, which should have been no surprise to me. The trick to landing the small one is not to slow it up like a slick low winger, but to fly it in on 25/30% right up to threshold and then cut. In truth it is a nice design and fun to fly, is a good aerobat, and looks great in the air. I would love a 40 sized one (which I think, is really a 60 sized air frame) - hence why I have a 40 size bipe project next in my build queue.
