hey,

I too am interested in this plane, but can't decide on the engine.

I'm stuck between a OS .55 ax, the OS .61 fx and the OS .75 AX

I hear a lot of good about the new ax-engines.

The intended flying-type is sporty (inverted, knife-edge, spins, stall-turns, snap-rolls, hover, cuban eights, ...) not really into 3D. But I do want to have enough power to pull out a hover.

Perhapse I should be looking at a 4-stroke, due to the angled installation??

Thanks for your advice.
Phil
