 Step 20
Loosen the setscrew on the wheel collar installed in Step
18. Slide it down so it is resting against the tail gear bracket
and tighten the 3mm setscrew. You may need to use a ball
driver to tighten this particular setscrew since you will be at
an angle accessing it through the slots for the tail gear doors
from the outside of the fuselage to do so. Make sure the
pushrod operates smoothly without any binding.
 Step 21
Use a pencil to mark the rudder where the pushrod crosses.
This will be used to center the horn vertically on the rudder.
 Step 22
Use a hobby knife with a #11 blade to cut a 1/4-inch (6mm)
piece of tubing from the 2-inch (52mm) safety tubing
included with the kit. Slide the tubing on a clevis, and then
thread the clevis 10 turns on the rudder pushrod.
 Step 23
Use side cutters to remove the backplate from a control
horn. Connect the clevis to the center hole of the control
horn. Set the backplate aside as it will be used later.
 Step 24
Center the rudder so it is in alignment with the fuselage.
When positioning the control horn, align the front edge of
the horn with the edge of the fixed surface as shown to
minimize any differential of the control surface. Locate the
centerline of the control horn vertically on the mark made in
Step 21. Use a pencil to transfer the locations for the three
control horn mounting screws onto the rudder.
 Step 15
Slide a 2.5mm wheel collar on the tail gear wire. Position the
collar 1 7 /
8
-inch (48mm) from the end of the wire as shown.
Use a 3mm setscrew and 1.5mm hex wrench to tighten
the setscrew. Use threadlock to prevent the setscrew from
vibrating loose.
 Step 16
Slide the 30 1 /
2
-inch (775mm) pushrod wire into the rudder
pushrod tube threaded end first. You will need to guide the
wire through the aft rudder pushrod tube and remove the
covering from the pushrod exit to allow the pushrod to exit
the fuselage.
 Step 17
Pull the wire back slightly so the connector on the steering
arm can be slid on the wire. Note the direction of the arm
with the connector facing to the bottom of the fuselage.
 Step 18
Slide the tail wheel wire into the bracket in the rear of the
fuselage. Slide a second 2.5mm wheel collar on the wire
from inside the fuselage. Use a 3mm setscrew to keep the
collar from falling off the wire. The collar shown should
be roughly 1-inch (25mm) from the end of the wire so the
steering arm can be installed. The position of this collar will
be finalized once the steering arm is secured.
 Step 19
The steering arm can now be slid on the tail gear wire. Slide
the tail gear wire so the wheel collar on the outside of the
fuselage is resting against the tail gear bracket. The position
of the steering arm will self-adjust in height on the tail gear
wire. With the arm perpendicular to the tail wheel, tighten the
3mm setscrew with a 1.5mm hex wrench to secure it to the
tail gear wire.
