++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++ That might throw off the harmony and stick forces between the elevator and ailerons requiring more or less movement or stick forces in pitch or roll. I'd recommend sticking with the designed geometry. Control surface stops should all be at the input source (stick and rudder pedals) and not at the control surfaces. This insures that only air loads are felt on the system and not input forces. It's also nice to make the stops adjustable as in a bolt head being the hard point with a locking nut to hold the adjustment. When you see the ground rushing up at you, pulling back on the stick so hard that you break something in the control system is not the way out of a bad situation. :-) Larry Flesner
