4. Temporarily position the aileron servo into the servo
bay with the servo spline towards the leading edge of the
wing. Drill a 1/16" [1.6 mm] hole through the four mounting
holes of the servo, drilling through the plywood mounting
plate in the wing. Install and remove a servo mounting screw
into each of the four holes. Apply a drop of thin CA into the
holes to harden the wood. After the glue has hardened,
install the servo into the opening. Cut three arms from a four-
armed servo arm (arms may need to be purchased
separately). Center the servo with your radio system and
install a servo arm parallel to the aileron hinge line as shown.

5. The aileron has a triangular block for mounting the
control horn. You can see the outline of it underneath the
covering by looking at the aileron at a shallow angle. If you
cannot see it, use your finger to lightly push in on the
covering until you find the edges of the mounting block.

6. Place a large nylon control horn on the aileron,
positioning it as shown in the sketch and aligning it with the
servo arm using a straight edge as a guide. Mark the location
for the screw holes. Using a 1/16" [2.4mm] drill bit, drill a 1/2"
[13mm] deep hole at the marks you made. (Be sure you are
drilling into the triangular mounting block on the bottom of the
aileron. Do not drill all the way through the aileron!).
Install and remove a #2 x 1/2" [13mm] sheet metal screw into
each of the holes. Harden the holes with a drop of thin CA.
After the glue has hardened completely, install the control
horn with two #2 x 1/2" [13mm] sheet metal screws.

7. Locate a .074" x 12" [1.9 x 305mm] pushrod wire
threaded on one end. Screw a nylon clevis onto the rod 20
complete turns. Slide a silicone clevis retainer onto the base
of the clevis. Connect the clevis to the second hole from the
bottom in the control horn.
