Dennis, the best CG is right behind the secondary spar as it comes into the fuselage. Look inside those top hatches and you can see the secondary spar. For low rates get the ailerons and elevators about 1.5" each way and the rudder 3". For high rates however much you can get. I like to mix flaperons with my elevator, meaning that both ailerons go down (start with one inch travel) when the elevators go up and vice versa. Take your time and start slow to get the feel, it flies and performs a little different than others. Once your comfortable cut loose, also could you post a picture? Jeff Williams
