The wing panels can be removed
once the epoxy has fully cured.

hinges using a cotton swab to prevent epoxy from
entering the hinge when attaching the stabilizer and
elevator.
9. Apply a small amount of 5-minute epoxy to each of the
elevator hinges.
10. Apply a small amount of 5-minute epoxy to each of the
elevator hinge pockets in the stabilizer.

ELEVATOR SERVO INSTALLATION
1. Prepare the elevator servo and install it in the fuselage
following the same procedure as the aileron servos.
Use a 24-inch (600mm) servo extension for the elevator
servo. Use the string located in the fuselage to pull the
servo lead to the receiver location.
2. Insert the 8-32 x 2 1 / -inch countersunk screw through
4
the hole in the elevator, then thread the 8-32 fl anged
nut partially on the screw. Remove the ball link from the
control horn, then thread the horn on the screw so it is
1
1 / -inch (32mm) from the surface of the elevator.

3. Apply thread lock to the screw before tightening the nut.
4. Use an 11/32-inch open end wrench to tighten the nut
against the elevator while holding the screw stationary
with a #2 Phillips screwdriver. Do not over-tighten the
nut, damaging the underlying wood.
5. Attach the ball link to the elevator servo arm so it is 1
inch (38mm) from the center of the control horn. Make
sure the tapered washer is between the ball link and
servo arm. Use a 1/4-inch nut driver and 3/32-inch hex
wrench to tighten the hardware.
