FLAP SERVO INSTALLATION
31.
Center the servos and install the servo arms on the servos
perpendicular to the servo centerline. Prepare both the right
and left fl ap servos.
32.
Remove the fl ap servo cover from the wing. Make sure to
mark the tray so it can be returned to the wing in the correct
direction.
33.
Follow the steps outlined for the aileron servos to install the
fl ap servos.
34.
The output of the fl ap servo will face toward the leading edge
of the wing.
35.
Use two rod ends and the 5
1
/
2
inch (140mm) threaded linkage
to construct two fl ap pushrods. Thread the rod ends evenly on
the threaded rod. Start with the linkage the length shown in
the photo.
36.
When attaching the linkage to the servo arm, use the hole in
the arm that is 5/8-inch (16mm) from the center of the arm.
Enlarge this hole using a pin vise and 1/8-inch (3mm) drill bit.
37.
Attach the ball end to the servo arm using an M3 x 12 socket
head cap screw, M3 lock nut and M3 washer. Tighten the
hardware using a 2.5mm hex wrench and 5.5mm nut driver.
38.
Insert the fl ap servo linkage into the wing. Place the fl ap
servo tray roughly into position, allowing the cover to be
moved so the linkage can be attached to the fl ap.
39.
Guide the fl ap servo lead to the root of the wing.
Use a tie wrap or string to secure the two leads
together. This makes them less likely to fall back
into the wing, and easier to retrieve if they do.
40.
Attach the fl ap linkage to the fl ap control horn using two M3
washers, an M3 x 15 socket head cap screw and an M3 lock
nut. Tighten the hardware using a 2.5mm hex wrench and
5.5mm nut driver.
Do not over-tighten the hardware and
damage the control horn or ball end.
