Nahh plane is pretty smooth on high rates.. I've got several compliments on the plane and how smooth it flies, it's on rails.. I do mostly scale type aerobatics, hammerheads, spins, cuban 8's, knife edge, inverted, it does all really well. Knife edge does require a small bit of up elevator but just a tiny bit, and inverted requires just a slight bit of down elevator. It knife edges pretty well, mine I only have low rate throw on the rudder and it will knife edge but you cant climb in a knife edge.. it will just hold a level flight.. I'm sure if I dialed in some more it would climb fine. I just got back from the field today and put 3 more flights on her.. I don't think you can go wrong with this plane, my only complaints are it's a little small (but hey it's a .40 size) and the wheel pants are horrible, mine only lasted 2 flying sessions of about 6 flights... oh yeah and I need more engine....
