2. Tie the string to the servo extension. At the root of
the wing the other end of the string is taped. Pull the string
and the servo lead through the wing. Untie the string from
the lead and insert the lead through the small hole you cut
the covering from. Tape the lead to the wing to prevent it
from falling back into the wing.

3. Install the servo into the servo opening. Drill
through the servo mounting holes with a 1/16" [1.6mm] drill
bit. Remove the servo from the servo opening. Install and
then remove a servo mounting screw into each of the holes
you have drilled. Apply a drop of thin CA into the holes to
harden the threads. Once the glue has cured, install the
servo into the servo opening using the hardware included
with your servo. Center the servo, then install a servo arm
as shown. The arm should be pointing towards the wing tip.

4. Place a nylon clevis in line with the last hole in the
servo arm. When positioned properly the control horn will
rest on a plywood plate in the aileron. Mark the location of
the mounting holes onto the aileron. Drill a 1/16" [1.6mm]
hole on the marks, drilling through the plywood plate but not
through the top of the aileron. Insert and remove a #2 x 3/8"
[9.5mm] screw into each of the holes. Apply a couple drops
of thin CA into the holes to harden the threads. Once the
glue has cured attach the horn to the aileron with two #2 x
3/8" [9.5mm] screws.

5. Thread a nylon clevis onto a .074 x 6" [152mm]
threaded wire 20 turns. Slide a silicone clevis retainer onto
the clevis. Install the clevis into the second hole from the end
of the control horn, then slide the silicone retainer over the
clevis. Drill a 5/64" [2mm] hole in the outer hole of the servo
arm. Center the servo and the aileron. With a fine-tip marker,
mark the wire where it aligns with the outer hole of the servo
arm. Make a 90° bend on the mark. Cut the wire so the wire
is 3/8" [9.5mm] in length after the bend. Insert the wire into the
servo arm and lock it in place with a nylon FasLink.

6. Repeat steps 1-5 for the left wing panel.
