Install the Aileron Servo & Pushrods
❏
1. Install the rubber grommets and eyelets that were
included with the servo. Mount the servo in the aileron servo
bay and drill a 1/16" [1.6mm] hole through each mounting
hole location. Do not drill all the way through the wing!
The holes should be just deep enough to accommodate
the length of the servo mounting screws. Remove the servo
and install and remove a servo mounting screw (included
with your servo) into each hole. Apply a couple drops of thin
CA into the holes to harden the wood. When the CA has
hardened completely, install the servo into the aileron servo
bay using the servo mounting screws with the servo spline
facing forward.
❏
2. Cut two arms from a four-armed servo arm as shown.
Enlarge the outer holes of the remaining arms using a 5/64”
[2mm] drill bit.
❏
3. Use your radio system to center the servo. Install the
servo arm perpendicular to the servo case.

4. Screw the aileron torque rod horns onto the threaded
ends of the torque rods fl ush with the ends of the rods.
Position the horns to point forward.

5. Screw a nylon clevis with a silicone clevis retainer onto
each of the 4-3/4” [120mm] pushrods 20 complete turns.
Connect the clevises to the aileron torque rod horns. Position
the ailerons in the neutral position with tape or small clamps.
Mark on the pushrods where they cross the outer holes in
the aileron servo arm.

6. Bend the wires 90 degrees at the marks and cut the
excess wire 1/4" [6mm] beyond the bends. Reattach the
