Thank you for that info. Im building the kit version of this plane and right now is trying to deside between an os 46 ax or an os surpass 52.

My pleasure to help a fellow modeler! Anyways, I'd suggest the bigger motor to give you some pull out power. I was reading in another youtube video that other guys were using .90 4 strokes on this plane.

I will say this though -- its a great flying plane. I really enjoy flying it. Does any aerobatics that I ask of it with nice precise accuracy. The flutter issue that you can hear in the video was related to the wings incidence being off, I've since corrected it. Flies great!

What kind of engine does it have?

This plane has a OS FS-70 surpass engine in it. Flies good with it, but can't do 3d.  Can't also go unlimited vertical
