3. Install the servo into the wing. Center the
servo and install a servo arm as shown.
Correct
4. Position a nylon control horn on the aileron as
shown in the sketch, aligning it with the servo. Mark the
location for the screw holes. Drill through the marks you
made with a 1/16" [1.6mm] drill bit, drilling through the
aileron. Secure the control horn to the aileron with two
2 x 20mm [3/4"] machine screws and the nylon
mounting plate.

5. Locate a 2 x 102mm [4"] pushrod wire
threaded on one end. Screw a nylon clevis onto the
threaded end of the wire 20 full turns. Install a
silicone clevis keeper onto the clevis and then install
the clevis in the second hole from the end of the
aileron control horn.
6. Be sure the aileron servo is centered.
Enlarge the second outermost hole in the servo arm
with a Hobbico Servo Horn Drill (or a #48 or 5/64"
[2mm] drill bit). Center the aileron and align the wire
pushrod with the hole in the end of the servo arm.
Using a marker, mark the location where the wire
aligns with the hole in the servo arm. On that mark
make a 90 degree bend. From the bend measure an
additional 3/16" [4.8mm], then cut off the excess
pushrod wire.
7. Install the wire into the hole in the servo
arm using a nylon FasLink as shown in the sketch.
8. Repeat steps I - 7 for the left wing panel.
