7. Cut two arms from a four-armed servo arm as shown.
Enlarge the outer holes of the remaining arms using a 5/64"
[2mm] drill bit.
❏
8. Use your radio system to center the servo. Install the
servo arm perpendicular to the servo case.
❏
9. Screw a nylon clevis with a silicone clevis retainer onto
each of the 6" [152.4mm] pushrods until the threaded portion
of the pushrod emerges from the clevis as shown. Connect
the clevises to the aileron torque rod horns. Position the
ailerons in the neutral position with tape or small clamps.
❏
10. Mark on the pushrods where they cross the outer
holes in the aileron servo arm.
❏
11. Bend the pushrods 90 degrees at the marks and cut
the excess wire 1/4" [6mm] beyond the bends. Reattach the
clevises to the torque rod horns and install the 90° bend in
the pushrods into the outer holes of the servo arms. Secure
them with two nylon FasLinks. Confi rm that the ailerons are
both in the neutral position with the servo arm perpendicular
to the servo case. If not, make the necessary adjustments by
threading the clevises up or down the pushrod. When satisfi ed,
slide the silicone clevis retainers to the ends of the clevises.
Wing assembly is complete.
