6. Cut a paper towel into approximately 2" squares.
Place the fuselage on it’s side so the fin and rudder are
horizontal. Add six drops of thin CA to the center of the
hinges on both sides. Use the paper towel squares to
absorb excess CA from the hinge gap before it cures. Do
not use CA accelerator; allow the CA to cure slowly.
❏
7. Use the same hinging method to join the elevators to
the stab and the ailerons to the wing.
❏
8. After all your control surfaces are securely hinged and
the CA has thoroughly hardened, move the control surfaces
back and forth to loosen them up a little so it will be easier
for your servos to move them.

1. If you haven’t already done so, install the rubber
grommets and eyelets in your aileron servos. Pull the string
out of one of the aileron servo compartments in the wing.
Tie the string to the servo cord on one of the aileron servos.
❏
2. Fit the aileron servo in the wing. Hold the servo to the
wing so the sides don’t contact the wing and drill 1/16"
holes for the servo mounting screws. Mount the servo to
the wing with the screws included with your servos.
❏
3. Mount your other aileron servo to the other side of the
wing using the same procedures as above.
❏ ❏
4. Cut the unused arms from one of your servo horns
and mount it on one of your aileron servos in the wing.
❏ ❏
5. Refer to the following photo. Use alcohol or other
solvent to clean the film of oil from the five .074" x 12" wire
pushrods. Screw a nylon clevis about fourteen turns onto
one of the pushrods. Connect the clevis to the second from
the outer hole of a nylon control horn.
❏ ❏
6. Hold the control horn on the aileron making sure
the holes align with the hinge gap. Use the control horn as
a template to drill 3/32" holes through the aileron for the
mounting screws.
