3. Position the servos in the aileron servo bays in the
orientation shown. Drill 1/16" [1.6mm] holes through the servo
mounting tabs. Thread a servo mounting screw (included with
the servos) into each hole and back it out. Apply a drop of thin
CA to each hole to harden the wood. When the glue has cured,
install the servos using the hardware included in the servo
hardware bags.

4. Thread a nylon clevis 20 complete turns onto each 6"
[152mm] pushrod. Slide a silicone clevis retainer onto each
clevis and connect the clevises to the outer holes of two
control horns.

5. Cut three arms from a four-armed servo arm for the
aileron servo. Enlarge the outer hole of the remaining arm
with a 5/64" [2mm] drill bit. Center the servo with your radio
system and install the servo arm to the servo perpendicular
to the servo case as shown. Be sure to reinstall the servo arm
screw into the servo.

6. Position the control horns over the hardwood blocks
embedded in the ailerons (if you cannot see them, hold the
aileron at a shallow angle in good lighting or use a small pin
to puncture the covering). Use the position of the servo arms
as a guide. Align the holes in the control horns directly over
the aileron hinge line and mark the location of the control horn
mounting holes.

7. Drill 5/64" [2mm] holes at the marks you made through
the hardwood blocks. Apply a couple drops of thin CA glue
