I have a 4* 60. I built a bigger rudder for it but never got around to changing the elevators.I have worked the balance point about 3/4" behind the recomended point. It hovers very easy. Dosn't have enough elevator to do all the 3D stuff but does make a great second plane and you can get started on some 3D with it. With bigger elevators it may do more.Make sure you double bevel your control surfaces so you can get 3D throws.
