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.

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.
