 6. Use a hobby knife to enlarge the holes in a
double-sided servo horn that is 1/2-inch (13mm)
from the center of the servo horn. The hole needs
to be big enough to insert the pushrod wires for the
ailerons. Use care not to make the hole too large
as this will cause slop in the control system.
 7. Install the servo horn on the aileron linkages by
inserting both linkages into the holes in the servo
arm. The arm is then rotated on the bends so the
splines face to the aileron servo.
 8. Use the radio system to center the aileron servo.
Secure the servo horn to the aileron servo using
the screw removed in the previous section of the
manual. You will need a #0 Phillips screwdriver to
tighten the screw.
 9. Check to make sure the aileron is aligned with
the trailing edge of the wing. If not, thread the
clevis in or out until the two are aligned. Make sure
to check both the left and right ailerons.
