Hook Up the Ailerons

Refer to this photo while hooking up the ailerons.

1. Same as was done for the plywood wing bolt plate, cut

the covering from the top of the wing for the aileron servo
mount plate
. Then securely glue the plate to the wing.

2. Drill appropriate-size holes in the servo mount plate for

your servo mounting screws—for most Futaba screws and

the screws that came with the S3156 servos shown a 1/16"
[1.6mm] drill is suitable.

3. Temporarily mount the aileron servo with the servo

mounting screws that came with it. Remove the screws and
servo, add a drop or two of thin CA to each screw hole, allow
to harden, and then mount the aileron servo.

4. Thread both plastic torque rod horns onto the aileron

torque rods about ten full turns each.

5. Turn on the transmitter and center the aileron trim.

Temporarily connect the ESC, receiver, aileron servo and

battery to center the servo. Make sure the aileron servo is
rotating the correct direction according to your transmitter
inputs.

6. Use a servo arm that will have mounting holes

12mm – 13mm [7/16" – 1/2"] apart and connect the pushrods

using the hardware shown—make sure the ailerons are
centered when you tighten down the screw-lock connectors
and use a drop of threadlocker on the threads (and on the
servo arm screw if it goes into a metal output shaft).

7. Since you’re working on your ailerons and have them

operating now, this would be a good time to set the aileron
throw as noted on page 18 (or, you could wait to set the
throws when you get to that part of the manual later).

Mount the Horizontal Stabilizer (Stab)

1. Test fi t the horizontal stabilizer (stab) into the fuselage

centering it so the exposed balsa in the middle is centered.

View the model from behind to see if the stab is parallel with

the wing. If the stab is not parallel with the wing, place a
small amount of weight (1 – 2 oz. [30 – 60 grams]) on the
high side of the stab. If that doesn’t bring it into alignment,
remove the stab and lightly sand the slot in the fuselage
where necessary to get the stab level.
