ASSEMBLE THE AIRPLANE
❏
1. Begin by centering the aileron servos with your radio
system. Cut three arms from two four-armed servo arms.
Enlarge the outer holes in the servo arms with a 1/16"
[1.6mm] drill bit. Attach the servo arms perpendicular to the
aileron servo cases using the servo arm screws (be sure to
make a left and right aileron servo).
❏
2. Attach a 6" [150mm] servo extension to each aileron
servo. Use tape or heat shrink tubing (not included) to secure
the connectors.
❏
3. Glue the servos into the aileron servo bays using CA
glue or epoxy. Route the servo leads down the servo lead
channel and through the slots near the center of the wing.
