I'm looking for a cheap knock-around bipe that is capable of some mild 3D.

How big are the control surfaces? Have you tried 3D? Does it harrier? How about knife-edge flight?

Does it have 4 ailerons or only ailerons on 1 wing? Would it be possible to modify it for 4 ailerons servos and use some HS-81 or HS-225 on all 4 surfaces?

I'd be using something more like the OS 50 given my altitude.

Flight report please.

Thanks a bunch.
