slots. Hint: If available, use a high-speed rotary tool to drill
the holes.

❏ ❏

6. Cut a small strip of covering from both sides of each

hinge slot. If this is not done, the covering may interfere with
the penetration of the CA into the slot and may also interfere
with free movement of the aileron.

❏ ❏

7. Coat the “arm” portion of the aileron torque rod and

the groove and the hole in the aileron where the torque rod
fits with epoxy. Join the aileron to the wing and the torque
rod with the hinges. If the hinges don’t remain centered,
stick a pin through the middle of the hinge to hold it in
position. Wipe away excess epoxy with a tissue.

❏ ❏

8. Remove the pins if you’ve used any. Adjust the

aileron so there is a small gap–just enough to see light
through or to slip a piece of paper through–between the
aileron and the wing.

❏ ❏

9. Apply six drops of thin CA to the top and bottom of

each hinge. Do not use CA accelerator. After the CA has
fully hardened, test the hinges by pulling on the aileron.

❏ ❏

10. Use a sharp #11 blade to cut the covering from the

wing for the aileron servo mount. Also cut a hole for the
aileron servo wire.

Refer to this photo for the following four steps.

❏ ❏

11. Glue the servo mount to the wing. Drill 1/16" [1.6mm]

holes through the servo mount for the servo screws. Add a
few drops of thin CA to the holes and allow to fully harden.
Mount the aileron servo using the screws that came with the
servo.

❏ ❏

12. Thread a 4-40 nylon torque rod horn onto both

aileron torque rods until the top of the horn is even with the
top of the torque rod.

❏ ❏

13. Make a two-arm servo arm by cutting two 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 pushrods will fit.

❏ ❏

14. Connect the servo to the torque rod horns with pushrods

made from two 6" [150mm] wire pushrods, clevises, silicone
