Guillow's P-40 RC Conversion
Hi Bembo9,
I tried that same conversion and have yet to get it flying. I wanted to run a Cox .020 in it with a micro flight pack. But imagine that "big" cowl with a 4" prop!!? The prop tips won't extend past the lower air inlet, so the prop is smaller than the front of the cowl! Naw. Also consider that a tiny spinner would also look kind of odd. A babe bee .049 engine might NOT be too powerful if subdued with an exhaust muffler, but the plane is getting heavy.
So to get a better look and maybe even come out ahead in weight, I put a geared 280 electric with (8) 270mAh NiMh and modern micro servos and tiny speed control...
And my battery pack has a bad cell and it flew all of 10 feet.
HOWEVER! Electric seems to me the better choice.
Sorry, no digital camera so I can't include pics.
Best wishes in your project!
Will
