PREPARE THE WINGS
Install the Aileron Servos
❏
❏
1. Enlarge the outer hole of the two remaining control
horns using a #55 drill bit. Glue the control horns to the
ailerons using thin CA.
WITH SERVOS CENTERED, POSITION
EACH ARM ONE SPLINE FORWARD.

2. Center both aileron servos. Reposition each servo
arm so that the long arm is one spline forward from being
perpendicular to the servo case. Clip off the remaining arms.
❏
❏
3. Clean each servo case with denatured alcohol.
Remove any label that will prevent you from gluing the servo
case directly to the servo bay cover and scuff the surface of
the case with some sand paper. To make it easier to remove
in the future, you may wrap the case in electrical tape or
heat-shrink tubing before you glue it in. Use medium CA to
glue a servo to the servo bay cover so that the
tip of the
servo arm is centered
in the opening.
NOTE:
This will set
the servo output shaft aft about 1/8" [3mm] from the center
of the opening.

4. As an alternative to gluing the servos in place, we
have provided 7 x 7 x 12mm wood blocks that you may use
to attach the servos to the servo bay covers. If you choose to
use these, make sure that you align the servo as detailed in
the previous step and then glue the blocks to the cover using
medium CA.

5. Connect each servo to a servo extension. Use heat
shrink tubing or one drop of medium CA applied to the
connector body to secure the servo lead to the extension.
Pull the extension leads through the center of the wing.

❏
6. Use eight 2 x 7mm sheet metal screws to secure the
servo bay covers to the upper wing. Thread in each screw and
then remove it. Remove the cover and wick one drop of thin CA
into each hole. Reinstall the cover and tighten the screws.
