Paul Marsh Posted September 9, 2018 Author Share Posted September 9, 2018 VQ Models P-39 Airacobra. 9ch Spektrum Rx, OS 61FS pre-surpass engine. This needs loads of channels, 2 flap, 2 elevator, 2 aileron(Y-lead) , rudder, throttle, flaps, retracts. Ran out of channels, so Y-lead is on aileron, which is ok, anyway...

Devcon1 Posted September 9, 2018 Share Posted September 9, 2018 That looks super. Always impressed by the thought process on the Airacobra in terms of motor and armament location.Can you not get all 9 channels allocated to each surface/ control? Let us know how it flies as this is my 50/50 warbird choice with a Hurricane. Always wondered why we can't do the same motor placement without the Centre of Gravity issues.

Peter Miller Posted September 9, 2018 Share Posted September 9, 2018 Posted by Paul Marsh on 09/09/2018 14:23:29: Flew the P-47. Flies well. Does anyone know who's kit it was? Also, Peter said the cockpit is awful. Why's that? Suppose it's a cartoon scale, as the wing is bigger proportion to a scale P-47, but it has a benign stall and flies quite easily, considering a warbird. (hence why it's been flown so much and looking old...) Also, altered the decals, as they were wrong and should not be on both wings. Look at a picture of a Razor back P47. Look at the windscreen. It extends further forward and has significant framing. A very noticeable feature in fact. Quote Link to comment Share on other sites More sharing options...
Richard Ashworth Posted September 10, 2018 Share Posted September 10, 2018 A lot less fancy than some of the superb models in the thread but my first build (stripes to put on when I know it flies!) Pegasus - Galaxy Hornet 52in span, 4.85 lb (2.2kg), battery in ready to go. Thumper 3548 900kv 750w Turnigy 4S 3000 Quote Link to comment Share on other sites More sharing options...

Peter Miller Posted September 14, 2018 Share Posted September 14, 2018 Just finished my MAK 15 MP, Russian Powered glider. from 1956 72" span, 616 sq. in area. weight 2lb 12 oz. Small electric power. Quote Link to comment Share on other sites More sharing options...
pete taylor Posted September 14, 2018 Share Posted September 14, 2018 Yet another interesting looking aeroplane! Where do you find 'em?.. It should fly extremely well at that weight - around 10oz/sq.ft I make it. Is that including all that fuselage area too? Quote Link to comment Share on other sites More sharing options...
Peter Miller Posted September 14, 2018 Share Posted September 14, 2018 Hi Pete Yes, all the wing area. Hoping to test fly tomorrow afternoon. Yes, just over 10 oz per sq ft Quote Link to comment Share on other sites More sharing options...
Erfolg Posted September 14, 2018 Share Posted September 14, 2018 Ah, yes, another convert, having seen the light, or is it drawn to the dark side. The model certainly has some appeal, in being visually unusual. Although I do wonder what the technical merits of the configuration were thought to be. Maybe it was modular, to be assembled near a border and a way of escaping socialism? Quote Link to comment Share on other sites More sharing options...
Ron Gray Posted September 14, 2018 Share Posted September 14, 2018 Not a patch on Peter’s but here is my birthday present from my wife, a Seagull Radial Rocket Laser 100 powered.

Bob Cotsford Posted September 14, 2018 Share Posted September 14, 2018 They're very pretty planes Ron, bit of a mini Bearcat look to them.. Does the u/c mounting look to be a sturdy design? I ended up converting my Black Horse Provost to torque rod legs as the supplied system couldn't cope with grass fields. Quote Link to comment Share on other sites More sharing options...

Quite a few of them built, To save money on aerotows they did this experiment powered by a 25 hp 5 cylincer radial two stroke. Work that one out!!!

Ron Gray Posted September 14, 2018 Share Posted September 14, 2018 @Bob - actually a lot better looking in the flesh than the box’s pictures. Quite narrow wings and tailplane and I was a bit worried about tip stalling at low speeds but stalks were nice and straight without wing dropping. Having said that, I do approach landings at quite high speed and use the flaps. I was worried about the u/c as there have been several reports of this being a weak point in the design and it does seem like they have improved it over earlier versions. However I got one landing a bit wrong and one wheel caught in the long grass at the side of the runway, this spun the ‘plane around and in doing so pulled one of the legs out of the wing. In fact it was the ply mount that was pulled out and on closer inspection there was a lack of glue plus lack of gluing area to mount the plywood to. An easy fix and upgrade as there was little other damage. Unfortunately there is no suspension in the legs and I was tempted to fit oleos to give it some bit for the time being I’ll leave it as is. But I can say that it handles grass fields ok (as long as you keep out of the rough!). By the way Bob, it’s your old 100 in the RR, with no silencer, it wouldn’t fit without pushing the already 25mm too far forward, engine further forward. Instead of the silencer I’ve used some flexitube andvdespite my reservations it is acceptably quite with a lovely note to it. Quote Link to comment Share on other sites More sharing options...
Bob Cotsford Posted September 14, 2018 Share Posted September 14, 2018 That's good to hear Ron. That motor has been replaced in the Provost by (no cringing now!) a 6S setup which pulls the model around almost as well as the Laser did. I suspect they make the u/c mount a weak point to save further damage but I do think they overdo things. Quote Link to comment Share on other sites More sharing options...
Ron Gray Posted September 14, 2018 Share Posted September 14, 2018 Ah but Bob, the sound, or in your case the lack of it! I agree with you about the u/c, make it a weak point to prevent more extensive damage, this is what the damage was Quote Link to comment Share on other sites More sharing options...
Bob Cotsford Posted September 14, 2018 Share Posted September 14, 2018 At least it looks to have pulled out cleanly (bar the covering damage), when I've had retract mounts pull out it's usually because the rear beam has collapsed and the retract takes a section of sheeting and a couple of ribs with it. Was it the usual ARTF rubbery non-penetrating glue holding it or as appears from the photo, not enough glue to tell what it was? Quote Link to comment Share on other sites More sharing options...

Peter Miller Posted September 15, 2018 Share Posted September 15, 2018 Nice one. David I got my MAK test flown today. Seriously unstable at full power. CG too far back but I got it down in one piee Needs the CG even further forward.i.e ON the LE at the centre not 30mm back! Quote Link to comment Share on other sites More sharing options...
Steve Dunne Posted September 15, 2018 Share Posted September 15, 2018 New model this week - Freewing BAe Hawk, 70mm EDF. Flies very fast, but well under control. 6 flights so far, getting used to it . Back on Terra Firma! Steve. Quote Link to comment Share on other sites More sharing options...
Paul Marsh Posted September 16, 2018 Author Share Posted September 16, 2018 Bought another P26. with a TT 91FS in it. The other has no wing tips, this one has. As I've got this one, might make a set for the other, although the clipped wing flies well, maybe better... One the count, my 586th model... when will I reach 600?
