The aileron servos are hooked up as flaperons using the aileron and flap channels on the AR7000. I used short 4 inch extensions at the receiver to make it easier to hook up the servos when installing the wing. Each servo also has a 12 inch extension on it to make it reach the fuse/ wing center. I am using HD 20ga. extensions from Taildragger RC. Again the same setup on the elevator and rudder servos with the exception of the length of the extensions.
