RE: Sky Shark P-40
I've got a Quadra 52 on mine and the engine is not broken in yet. I'm turning a Master Airscrew 20X10 and only getting around 4800 RPM on the ground, but the engine is unloading in the air. On yours, I would think that an 18X10, or even a 20X10 would work.
Props are a lot like women, have to try different ones until you find one you like. Good luck.

RE: Sky Shark P-40
I have a 45 cc engine from FTL (China). I have used an 18x6-10 and am currently using an 18x10. In the air it flies pretty decent. On the ground for take off it seems to take a long time to get rotation speed and there by I am having a tough time keeping her on the straight and narrow. Could be new engine not putting out like it will when it gets more broken in? Or it's the pilot.
