Wreckman, I had this plane with a ST 75. Loads of fun, although, if I had to do it again would go w/ the kyosho arf(same overall cost and excellent workmanship on the one I looked at). I flew one with a os 61 and thought that it flew much better. I have attributed this mainly to my leading edge on the GP so yours certainly could fly as well/better than the Kyosho. I second the control surface comment, this plane stalls quickly(by design). It does the snaps rolls so quickly youll question if it actually did it. Using nylon bolts on the landing gear will help with those rough landings. I think it was on RCOnline, a fellow there went completely overboard on making this plane light, CF and Nomex all over the place, I think his came in around 4 lbs! I landed mine in a tree, RIP.
