Yep, my .75ax ran well on an 11x9APC in an 8lb Curare (old school pattern ship) and pulled ok as well with an APC11x10. 5% nitro, 22%oil

I currently run a 12x8 APC cut down to 11.5x8-ish. I'm ground limited to 12" diameter max and know I giving away heaps of static thrust but the engine's happy and the plane likes it. If you're stuck with ground clearance and noise issues then more blades would be a good way to go rather than adding pitch for a trainer OR just as good is to learn early on what a throttle is for and reduce it a bit after takeoff rather than fly around flat out.

Cheers
