3. Use the string in the wing to pull the servo wire for the
right aileron servo out the end of the wing.
❏
4. Wet the plywood aileron horn with thin CA, allow to
soak in and harden, and then lightly sand smooth.
Refer to this photo while mounting the aileron servo.

5. Mount a screw-lock connector in the side of the aileron
horn that faces outward (toward the wing tip)—be certain the
plastic retainer snaps on tightly. If not, use another (a couple
of spare servo retainers are included). Test-fi t, then securely
glue the horn into the slot in the aileron.
❏
6. Connect an aileron pushrod to the hole in the aileron
servo arm closest to 7/16" [11mm] out from center and fi t the
other end of the pushrod into the screw-lock connector on
the aileron control horn.

7. Temporarily lock the pushrod to the connector with a
2mm screw. Use your transmitter to operate the servo and
aileron, making sure everything moves smoothly. Cut the
hatch cover to fi t it over the pushrod and test-fi t to the wing.
Make sure you can get the hatch positioned so the servo arm
and pushrod will not hit the cover—this may require adjusting
the pushrod in the screw-lock connector to move the servo
forward or aft.
OPTIONAL SERVO MOUNTING METHOD
A note about gluing in the aileron servos:
Zap Goo (or similar) is preferred for gluing in the servos
because it is plenty strong, but if ever necessary, the servos
can be extracted by twisting them out. And then, remaining
Zap Goo can be peeled out of the wing and off the servos.
An optional way to glue in the servos is to wrap them tightly
with a layer or two of masking tape, and then glue them in
with epoxy or CA. If removal is ever required, cut the tape
and extract the servo. Remaining tape and glue will have
to be removed before installing another servo.
