Kyosho P-51D just about ready to go, just the decals on the cowl and the dummy exhaust stacks to fit. Have had this one sitting in the box 80% finished since 2004 when I did the electrification. AXI 4120/18, 5s1p 5000mah G-power Lipos, 4 max 80amp ESC, APC-E 13x10" prop. I've given the Mustang a going over with the heat gun since taking this picture this morning - that pre-printed sticky back plastic covering doesn't half wrinkle when it;'s warm.

Prompted to finish her off by comments on the recent Warbirds Replicas thread on here, extolling the flyabilioty of the Kyosho SQS ARTF warbirds.

This was rescued off a club member a week or two back, covering was stripped off and I renovated the structure which was in bad shape. I then converted it to electric power before recovering, just the servos and push rods to install and its ready for a re maiden. One of my earliest memories was my dad having one of these, if it goes ok I will grab some footage.

I covered this in HK covering which is the first time I have used it, have to to say I am impressed !

Hi Richard, I do like your Galahad, I've been thinking of building one as a first step into low wing aircraft, could you please tell me what electric set up you used.

Regards, Dave P

Hi Dave,

I have used a Turnigy Aerodrive D3530/14 which is 1100KV, with a 40 amp ESC. I have had it on the meter and with a 11 x 5.5 prop fitted its puling around 200watts/20amps (ish), but this is off a very old 3s Nanotech. There seems plenty of thrust so I am hoping I can prop it down when I get it up the field.

Have been advised off a vintage FB group to increase the rudder area, especially if its going to be flown in the wind which I will do before venturing out.

Rich

Forgot to add this video from Sunday, I am sure he wont mind me putting this here. Those who have been reading his column will know all about this, Mr Tim Hoopers 70% Antares aerobat which is powered by a PAW 1.5cc Diesel.

This is its second flight, goes really really well.

Walt Good's "Big Guff" replica. 8ft (2.4 metres wingspan.) (Over) powered by a Laser 70.

The Big Guff was one of the first model aeroplanes specifically designed for radio control.

It flies nicely Ken but like any big vintage model, it's not the sort of thing to fly on a breezy day. I flew it twice yeaterday with the engine barely over tick over most of the time.It was very economical on fuel. I'm going to try a finer pitched propeller on Wednesday but something like an OS 52FS would fly it I'm sure.

Nice job David, looks like a lot of solatex was needed!

My Galahad has was flown over the weekend and I did manage to get some footage, though it was late on so the light isn't great, I tried to keep it in as close as I dare.

It does go well and there is more than enough power, my only issue is it is reluctant to turn right under power. So I will prop it down as I'm guessing I'm fighting the torque reaction from the prop, I did add some right thrust which helped but I didn't feel in control at times.

With this and the new larger rudder I'm hoping to have better results, weather is looking more promising again so hope to get out with it later in the week all being well.

Another one ready for a maiden, a JP Panic. NTMPropdrive 4258 500kv motor, space for a 6S 4000mAh pack, Neuron 60A esc, APC 14*7-E prop giving just over 800W. Pity I've just been told to shield until the end of the month!

This is my recently finished depron MBB-Rockwell X-31 vectored thrust 70mm EDF.

Built from a Steve Shumate plan, it's the second one I've made as the first one I built two years ago was jinxed with a faulty EDF motor, and was written off at the start of only it's 6th flight following a particularly bad hand launch by an over confident 'newbie'.

This one hasn't had its maiden yet, and will hopefully survive for longer than the first.

Note the vector-thrust vanes at the back. Unfortunately I had just overcome the motor problems with the first, and carried out the initial trimming flights when it was written off, so I never got a chance to explore the thrust vectoring capabilities.

Nice MBB-Rockwell X-31 you have there, best of luck with the maiden. Quick question, is the canard fixed or does it move? If so what have you got in mixed into?

Bob I like your Panic and from just finishing and flying my translucent Extra Slim Twin can you comment on recognising the orientation of yours as mine can be really hard with sun shining through it?

Quite a few years ago a clubmate had a Vecjet I think it was called. Very impressive in the vertically downwards twizzles. I tried to emulate one with a swivel motor but it was a pig.

Thanks Chris.

The canards move on their own servo. It's all on quite a complicated mix on my DX8 actually;
The canards are on the primary elevator channel, with an elevator to flap mix for the elevons, and an elevator to gear mix to drive the elevation thrust vane. This (the el to gear mix) allows the vectoring to be switched on/off during flight with the flight mode switch if required.

The yaw vane is mechanically slaved off the rudder. You can't switch that off, but then you don't have to use the rudder to fly.
