UT 4 aileron servo mounts from the
1
⁄
4
" x
3
⁄
8
" x 6" basswood strip. The lengths are
shown on the plans. Note that the aft mount
is shorter than the front mount.
Drill
1
⁄
16
" diameter holes in the mounts to
match your servos. The servo is attached to
the bottom of the mounts, as shown. Use the
special #2 Allen head sheet metal screws and
wrench from the hardware package to mount
the servos. Remember to reverse the eyelets
that came with your servo to allow for this
“upside-down” mounting.
Lay the servo and mounts on the
bottom
of
the wing, and mark the area for the cutout.
Cut out the skin with a knife. Use a knife or
Dremel tool to remove the foam. Be careful not to cut into the
upper wing skin.
Trim the top of the mounts until the servo is flush with the
lower wing surface. Epoxy the servo mounts in place. The
mounts should be glued to the upper skin and the edge of the
lower skin.
Remove the servo. The enclosed “ball end” Allen wrench
allows easy removal of the servo screws.

RIM the two

⁄
8
" x 9" balsa strips to
fit in the aileron cutout as shown. Glue in
place. Glue one of the die cut W-1 pieces on
each end of the cutout as shown.
Cut about
1

4
" from the end of each aileron so
it will fit back in the opening. Trim the lead-
ing edge of the aileron to allow for the thick-
ness of both the wing trailing edge strip and
the
3
⁄
16
" thick aileron leading edge strip. Glue
the aileron leading edge strip in place. The
aileron trailing edge should match up with
the wing trailing edge with both strips in
place when you are done.
Sand one end of the aileron smooth. Glue a
W-1 in place. Trim the other end to allow for
the thickness of the other W-1, plus about
1
⁄
16
" extra clearance
as shown on the plans. Glue the final W-1’s in place.
When the glue is dry, sand all of the framing pieces flush with
the wing skin. Remember to protect the wing surface with
masking tape while sanding.
