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
