hole with CA. Attach the servo cover to the wing using four

2mm x 9mm wood screws.

9. Repeat Steps 1-8 for the other aileron servo.

ASSEMBLE THE FUSELAGE

1. Inspect the hinges and the hinging motion of the

elevator now and before each flight. Cut the 10-24 x 2"

[52mm] nylon bolts to 3/4" [19mm] long. Attach the stab to the

fuse using the two nylon bolts. Be careful not to overtighten.

2. Cut the remaining small control horn as shown. The horn

is installed centered on the opening in the top of the fin and the

base of the horn is 1/2" [12mm] back from the hinge line. Install

the control horn using two 2-56 x 5/8" [16mm] bolts and the

nylon backplate. Remove the stab from the fuselage.

3. Remove the elevator servo hatch cover and set aside

for now. Cover the elevator servo with Trinity single cell heat

shrink as you did before on the aileron servos.

4. Connect a 24" [610mm] servo extension to the elevator

servo. Secure the connection with 3/8" [10mm] heat shrink

tubing. Route the servo lead through the fuselage.

5. Temporarily position the elevator servo as shown. Use

fine-grit sandpaper to sand the area on the fuselage and

heat shrink wrap where the servo will be glued. Note:

Alternatively the servo can also be installed right-side up.

6. Thread a nylon clevis and retainer onto a 2mm x

150mm threaded pushrod. Make a Z-bend approximately

4-1/4" [108mm] from the end of the threaded end of the rod.

Connect the Z-bend to the elevator control horn & reinstall

the stabilizer while sliding the pushrod into the fin.

7. Center the servo and attach the clevis to the servo

arm. Shift the servo to get the elevator neutral and the top

of the servo parallel with the pushrod.
