5/8"
Measure 5/8" back from the trailing edge of
4.
the wing along the mark you made for the
control horn. Drill a 9/64" hole at this location.
Make the hole perpendicular to the trailing
edge of the wing, not square to the surface of
the aileron.
Insert the 6-32 bolt through the ailerons from
5.
the top side. No washer goes on the top.
Place the nylon washer on the bottom side
and screw the nylon nut in place. The nut will
self tap onto the screw but it is much easier if
you run a 6-32 tap through the hole first. Run
the tap through the control horn fitting also
and screw into place. Leave it flush with the
top of the screw or one thread down(1/32") to
provide the mechanical leverage needed.
Repeat for the other aileron and both flaps.

Locate the 4-40 pushrods and thread a nut
6.
and a clevis with silicone keeper on one end.
The aileron pushrods are 1\4" longer than
the flap pushrods.
7. Screw the other end of the pushrod into the
nylon pushrod fitting. It should screw in to
the opening in the back of the clevis. Center
the aileron and servo and attach the clevis to
the output arm on your servo. Adjust the cle-
vis to fit.
