12. A mechanical/pneumatic nose gear steering pushrod
template is provided at the back of this manual. Use a 17-1/2"
[445mm] pushrod to make the steering pushrod. The threaded
end will not be used. Insert the pushrod through the other hole
you made in the wheel well. The short bend in the pushrod
fi ts into the link on the retract steering arm (you will need to
enlarge the hole in the link to 5/64" [2mm]). The other end fi ts
into the screw lock connector on the rudder steering servo
arm. Test the operation of the steering with your radio system.
Adjust the pushrod as necessary for bind free operation.
❏
13. Locate the two small nylon disks and two nylon torque
rod horns as shown. These parts will be used as steering
pushrod guides.
❏
14. Remove the steering pushrod from the fuselage. Slide
the torque rod horns onto the pushrod and reinstall the pushrod
in the fuselage. Space them evenly apart as shown and mark
the positions of the mounting holes onto the retract rail.
❏
15. Drill 1/16" [1.6mm] holes at the marks you made. Thread
a #2 x 1/2" [13mm] self-tapping screw into each hole and back
it out. Apply a drop of thin CA to each hole and let the glue
harden. Align a nylon disk over each hole (a drop of CA will
hold them in place). Attach the torque rod horns using two #2
x 1/2" [13mm] self-tapping screws. Secure the forward end
of the pushrod to the steering link on the retract with a 3/32"
[2.4mm] wheel collar and a 4-40 set screw. Test the operation
of the steering again with your radio system and make any
necessary adjustments.

16. Choose a location for the fi ll valve on the side of the
fuselage. The location should be out of the way of servos and
the other retract hardware. Drill a small hole at your chosen
