11/32" [8.7mm] from the center of the servo. Enlarge the holes
that are 11/32" [8.7mm] from the servo centers using a #60
drill bit. If you do not have this size drill bit, you can use a
hobby knife to enlarge the holes but work slowly while test
fi tting the aileron pushrod wires into the holes until you have
a snug fi t. Be sure to prepare a left and right servo. Reinstall
the servo arm screws.

2. Lightly sand the sides of the servos that will be glued to
the wings. Clean the servo cases with alcohol. Use medium
or thick CA to glue the aileron servos into the servo bays in
the wings as shown. Route the aileron servo leads through
the holes in the wing roots as you set the servos in place. Be
sure the aileron servos are glued square to the root ribs and
are positioned as far toward the trailing edge and root rib as
possible. Note: when gluing the servos in place, use several
dots of glue. Do not saturate the servo with glue as you may
need to remove it for repair or replacement.
Also, take care
not to get glue in the joint between the top and bottom
servo case halves
. Doing so can allow glue to seep into the
servo and into the servo gears.

3. Use a few dots of medium or thick CA glue to attach the
aileron servo covers over the servo bays. The raised portion of
the servo covers should be toward the trailing edge of the wing.

4. Trim the mounting plate from a control horn. Enlarge
the outer hole of the control horn with a #56 drill bit (if you do
not have a #56 bit, use a hobby knife to carefully enlarge the
hole to fi t the screw lock pushrod connector shown in step
7). Fit the Z-bend of a 3-15/16" [100mm] into the enlarged
hole of an aileron servo arm. Using the pushrod as a guide
(keeping it parallel with the wing root rib), position a control
horn onto the aileron so that the holes in the control horn
are positioned directly over the aileron hinge line. Push the
control horn against the aileron with adequate force so the
mounting posts make indentations in the aileron. Repeat this
step for the other aileron.

5. Drill 3/32" [2.4mm] holes through the ailerons at the
indentations made by the control horn mounting posts.
