Drop the servo into the pocket again. Insert the pushrod into the arm.
Verify that the servo is sitting flat and has some space at both
fore/aft walls of the pocket. Temporarily tape the servos into the
pocket to prevent them falling out during the next step.
Lift the control horn off the slot. Apply medium CA or epoxy into
the slot.
Install the control horn permanently now. Remove excess glue if
needed. Try to avoid getting glue onto the hinge line!
Important! Keep the servo arms in their exact offset position by
plugging the servos into the receiver with a battery, and keep the
ailerons taped to the wing roots. Make balsa shims that will go on
both sides of the servo and wedge the servo inside the pocket
slightly. Do not use excessive force or the top wing skin will warp at
the pocket and you will have a visible bad spot there, both visually
and aerodynamically.
