Because this fit will be different on every air-
plane, you may need to lightly sand the sides of
the blocks so they will fit properly.

6) When satisfied with their fit, remove the two
blocks. Using Kwik Bond Thick C/A, glue the two
hardwood blocks to one side of the plywood aileron
servo tray. One block should be glued flush with the
outer edge of the tray and the second block should be
glued flush with inside edge of the servo cutout. Both
blocks should be centered between the sides of the
tray. See photo # 31 below.
hole and the "V" shape should match the angle of
the top wing sheeting. See photo # 30 below.

7) Test fit the aileron servo tray assembly into
the wing. The portion of the tray that overhangs the
hardwood block should face the trailing edge of the
wing and the whole assembly should be pushed down
firmly into the hole. See photo # 32 below.

8) When satisfied with the fit, remove the servo
tray assembly. Mix up a generous amount of Kwik
Bond 30 Minute Epoxy. Apply a thin layer of epoxy
to the gluing surfaces of each of the two hardwood
blocks. Reinstall the servo tray assembly and align it
as done previously. Any excess epoxy can be removed
using a paper towel and rubbing alcohol. Allow the
epoxy to fully cure before proceeding.
INSTALLING THE AILERON SERVO
q
9) Locate the servo you intend to use for aile-
ron control. Install the four rubber grommets and four
brass collets onto the servo. The brass collets should
be installed with the flanges facing the bottom of the
servo mounting tabs. See figure # 5 below.
q
10) Position the servo into the servo tray mak-
ing sure you run the servo wire out between the tray
and the wing. Note the position of the servo output
shaft. It should face the leading edge of the wing.
See photo # 33 below.

11) Using a 1/16” drill bit, drill pilot holes
through the servo tray for each of the mounting screws.
Install the servo using the mounting screws provided
with the servo. Tighten the screws firmly to hold the
servo in place.
Drilling pilot holes through the servo tray will
make it easier to install the mounting screws.
Be careful not to drill through the top of the wing.
