I don't even think my ailerons run the full travel as called for in the plans, and they do everything I need them to do so far. You can easily limit the travel at the stick later, if you feel the need.
The new airfoil results in a pretty stiff aileron feel at high speed. The first time I really wound mine out, I thought the ailerons were locked up! I plan to "delete" the cusp on the bottom of the airfoil next time I have them off the plane (maybe this summer), which I think will help unload the control system and make them easier to move at speed.
