8. Make a one-arm servo arm by cutting three arms
off a four-arm servo arm. Enlarge the holes in the arm with
a Hobbico
® Servo Horn Drill (or a #48 or 5/64" [2mm] drill bit)
so the pushrod will fit. Connect the servo lead to the
receiver. Turn on the transmitter and receiver to center the
servo. Place the servo arm on the servo so it is pointing
straight towards the fuse.
❏ ❏
9. Attach the clevis with pushrod to the outer hole of the
control horn. Hold the aileron straight with the wing and mark
the pushrod where it crosses the servo arm. Bend the pushrod
90 degrees away from the wing on the mark you made.
❏ ❏
10. Attach the pushrod to the control horn. Attach
faslink and cut off the excess pushrod. Be certain to leave
1/16" [1.6mm] of wire protruding from the Faslink as shown
in the photo.

11. Repeat steps 2-10 for the other left side of the wing.
❏
12. Slide a silicone retainer over the two servo wires so
they won’t fall back into the wing.

1. Mount the wing to the fuse with the two 1/4-20 x 2"
