6. At the rear of the fuselage on both sides, cut away the

covering where the pushrod tubes exit the fuselage.

7. Install the rudder and elevator nylon control horn in

line with the servo pushrod. The rudder horn should be

mounted on the left side of the fuselage and the elevator

should be mounted on the right side of the fuselage. Hold

the horn in position and mark the location of the mounting

holes. Drill 3/32" (2.4mm) mounting holes through the

marks. Wick two to three drops of thin CA into the holes to

harden the underlying balsa, then re-drill the holes. Attach

the horns using #2 x 1/2" (13mm) Screws and Nylon Nut

Plates. Do not over-tighten the screws, crushing the

underlying balsa.

❏

8. Locate the two longest threaded wire pushrods and

screw a nylon clevis on each one approximately 14 turns.

Place a silicone retainer over each of the clevises. Insert

the pushrod into the plastic tube. Attach the clevis to the

control horn.

❏

9. Mark the pushrod where it crosses the servo arm.

Enlarge the servo horn hole with a 5/64" (2mm) drill bit.

10. Make a 90-degree bend in the pushrod on your mark,

then insert it through the enlarged hole in the servo arm. Cut

11. Follow the same steps for the rudder except you will

need to use the two arm type control arm on the servo.

Attach the rudder pushrod to the outside arm and the

nosewheel to the inside arm.

❏

12. Install a Brass Screw-Lock Pushrod Connector

with the 4-40 x 1/8" (3mm) Cap Screw on the servo arm

with the rudder. Snap the Nylon Retainer onto the screw-

lock pushrod connector post beneath the servo horn.

❏

13. Assemble the Nose Gear Pushrod Wire by installing

a nylon clevis about 14 turns and a silicone retainer onto the

threaded end. Slide the nose wheel steering pushrod into

the outer tube located on the lower left side of the firewall.

❏

14. Insert the wire into the connector, adjust the nose wheel

and tighten the cap screw. Minor adjustments to the steering

can be done either at the clevis on the nose wheel or by

adjusting the wire position at the screw-lock pushrod connector.

15. Use the following sequence for mounting the servos

into the wings.

❏

A. Install rubber grommets and brass eyelets in the

servos using the provided sketch.
