7. Locate the aileron servo mount and remove the covering from this area. Use a sealing
iron to seal the edges of the covering to the sides of the servo opening. Take a few minutes
to apply some CA to the joints of the servo rails and the ribs.
8. Attach a 12" servo extension to your servo and secure with thread or heat shrink
tubing. Use the manufacturer supplied mounting hardware and install the servo with the
output shaft toward the trailing edge of the wing. Electronically center your servo.
Aileron servo arm length should be 1.50". We use and recommend the SWB double lock
aluminum arms. Thread 2 ball links onto the titanium turnbuckle pushrod. Secure the
pushrod to the control horns and servo arm as shown in the picture using the supplied
3mm bolts and nylon insert locknuts. As always, use blue Loctite on ALL bolts!
