I have the control surfaces set to max values but I still have a problem. On both the elevator and rudder I am getting much more travel on one side compared to the other. The up elevator is about 1/2 less travel than the down elevator and the left rudder is twice as much as right rudder. I only know how to change the overall travel through the TX but don't know how to increase up elevator without changing down elevator and the same thing for the rudder. How do I get them even? The link points on the servo arms and horns are about as good as I know how to get them although the control rod for the Rudder is too short so I can just barely get it screwed down where it want slip out. Help!!
