I fly mine with a 91fx and love it. I am running a 13-8 and it is pretty fast. I haven't tried propping it for speed. What would you guys suggest if I wanted to prop for speed. The only problem is it takes long enough now to bleed off speed. I replace my gear with heavier wire. It helped, but I still get noseover in grass.

Great plane though, solid as a rock in the air.
