11. Secure the servo to the cover using a 2mm hex wrench
and the screws provided with the servo. 16. Place low-tack tape on the aileron around the control
horn opening. This will keep the glue from getting on the
aileron. Removing the tape before the glue cures will
leave a fi llet between the control horn and aileron for a
fi nished look.
12. Center the servo, then secure the servo arm so it is
perpendicular to the servo centerline. The clevis will
attach to the arm 1

inches (30 to 40mm) from
the center of the arm.
17. Apply a small amount of 30-minute epoxy into the slot in
for the aileron control horn.
13. Tie or tape the string located inside the wing to the end
of the servo lead. Use the string to pull the servo lead
through the wing and out at the root. 18. Apply a small amount of 30-minute epoxy to the base of
the control horn using a toothpick. Insert the control horn
into the slot. Remove any excess epoxy using a paper
towel and isopropyl alcohol.
14. Secure the servo to the wing using four #2 x 3/8-inch
sheet metal screws. Use a #1 Phillips screwdriver to
tighten the screws. 19. Remove the tape before the epoxy has completely cured.
This will allow the epoxy to fl ow between the control
horn and aileron, creating a small fi llet. Remove the
screw from the control horn after the epoxy has fully
cured. Install all the control horn at this time.
15. Sand the lower portion of the control horn where it fi ts
into the aileron using medium grit sandpaper. Clean the
oils and debris from the sanded area using a paper towel
and isopropyl alcohol. 20. Remove the clevises from the pushrods. Slide a silicone
clevis retainer over the barrel of the clevis. Thread the
clevis back onto the pushrods. Prepare all the clevises at
this time.
