Cotter Pin

Pin Washer

11. While you have your wings on your workbench and

the servos operating, you could go ahead and set the control
throws as indicated on page 21 now, or wait until the model
has been completed. Once the aileron throws have been set,
fasten the lock pins to the clevises and control horns with a
pin washer followed by a cotter pin. Bend the cotter pins
over so they won’t come out. Secure all the servo wheels
to the servos with the screws that came with them. Note: If
your servos have metal output shafts, use threadlocker on
the threads of the servo arm screws.

12. Use CA or rubber cement to glue the black, foam

rubber strips to the end of both wings.

ASSEMBLE THE HORIZONTAL STABS

1. Install a 3" [75mm] torque rod in both elevators with

the torque rod washers and torque rod nuts. Also cut the
covering from the elevator servo openings in the horizontal
stabilizers (stabs).

2. Mount the elevator servos and hook up the elevators—

all the hardware is the same as was used for the ailerons

except the turnbuckle pushrods are 3-1/2" [90mm] in length.
Also remember to harden the screw holes for the servo
mounting screws.

3. Wet the mounting tabs on the ends of both stab halves

with thin CA. Allow the CA to penetrate into the wood
and harden.

4. When ready to set the throws or check the C.G. and

you need to mount the stab halves to the fuselage, use the
carbon fi ber stabilizer tubes and two 4-40 x 1/2" [13mm]
SHCS, #4 lock washers and #4 fl at washers in each stab.
When mounting the stabs for fl ying, use threadlocker on
the threads of the screws.

ASSEMBLE THE FUSELAGE

Mount the Landing Gear

First the tail gear…

1. Temporarily remove the tail wheel bracket from the tail

gear wire with a 1.5mm Allen wrench. File a fl at spot in the wire
for the set screw in the bottom collar. Reassemble the tail gear
with a drop of threadlocker on the threads of the set screws.
