12. Find the servo that will be used on the right aileron.
Cut down a large servo arm (the distance from theservo arm
screw to the outer servo arm hole should be at least 5/8”
[16mm]). Install the servo arm at 90 degrees to the servo
case. Position the servo on the servo cover so that the servo
arm is located in the middle of the slot as shown in the image
above. Outline the servo and servo mounting lugs.
❏ ❏
13. Locate two 13/16" x 3/4" x 3/8" [20mm x 18mm x
10mm] hardwood blocks. These will be used to mount the
servos to the aileron servo cover. Mix a small amount of
epoxy. Glue the hardwood blocks along the servo mount
outlines. Make sure the grain of the hardwood blocks runs
vertical with respect to the servo cover.
❏ ❏
14. Position the servo between the hardwood blocks.
Mark the holes for the servo screws on the hardwood blocks.
Remove the servo and drill the holes with a 1/16" [1.6mm] drill
bit. Wick some thin CA into the screw holes. Install the servo.

15. Feel through the covering the servo lead exit hole
at the center section of the bottom sheeting of the top wing.
Remove the MonoKote. Connect a 6" [152mm] servo
extension cord to one of the ends of the “Y” harness. Use
shrink tubing, tape or clips to secure the connection. Tie the
end of the 6" [152mm] servo extension to the string and pull
the extension and one leg of the “Y” harness through the
wing until it reaches the correct aileron's servo bay.
❏ ❏
16. Connect the servo extension to your servo lead.
Use shrink tubing, tape or clips to secure the connection.
Gently pull on the “Y” harness until most of the servo wire is
hidden in the wing. Mount the servo cover with the servo to
the wing. Depending on the size of your servo, you may have
to trim one of the wood blocks slightly.
