Well my father-in-law brought his plane and I flew it a couple of times.....Both times till she ran out of fuel. This is definitely more of a pattern plane than 3D....which is pretty obvious just by looking at it. Thin wing small surfaces. I think for the size, it is a bit heavy as it seems to be at it's best flying at a decent speed. Slow flight is no problem, but not the best. He has a 60 size engine on it and it seemed to be a about the right combo. No need for an oversized engine on this plane as the airframe won't really allow you to use it for anything other than more speed. My father-in-law had the idle set a little high, so flat spins were difficult to enter. Overall, a decent flying plane.
