7. Drill 5/64" [2mm] holes at the marks you made
through the aileron (drill perpendicular to the aileron chord
line). Apply a couple drops of thin CA glue to each hole to
harden the surrounding wood. When the glue has dried,
install the control horn onto the aileron using two 2 x 20mm
machine screws and a control horn backplate. The excess
length of screw protruding beyond the backplate can be
cut off.

8. Use tape or a small clamp to hold the aileron in
the neutral position. Make a mark on the pushrod where it
crosses the outer hole in the servo arm. Make a 90 degree
bend at the mark on the pushrod and cut off the excess
pushrod 1/4" [6mm] beyond the bend. Attach the pushrod to
the servo arm using a 90 degree pushrod connector. Thread
the clevis up or down on the pushrod as necessary to center
the aileron with the servo arm centered. When satisfi ed,
slide the silicone clevis retainer to the end of the clevis to
secure it.
9. Route the servo lead through the hole in the top of
the wing panel and tape it back and out of the way.
10. Repeat steps 1-9 for the other wing panel.
