Connect the fuel pickup from the center tank to the optional UAT
or to the fuel pump. In the prototype, the UAT is located just
above the right intake. (

Step 4: Nose gear
Working from inside the aircraft, screw the nose steering servo
to the bracket (
photo 12
). Do not use rubber grommets and
make sure to use Loctite on the screws. The servo is oriented
with the output spindle toward the top of the plane. If your
servo has a reinforcing ridge on the mounting tab, you may
need to remove it with a razor knife to allow the servo to sit flat.

Lower the gear.
Adjust the steering arm clevises until they are approximately the
same length, with the servo arm positioned on the servo spindle.
Using a Matchmaker or similar device, center the servo and
mount the arm. Readjust the clevis if there is any evidence of
binding (

).
When satisfied, use a small drop of thin CA on each clevis to lock
it on to the threaded rod.
Step 5: Nose Doors
It will be helpful at this point to locate the positioning of the air
system valves. A sample installation is shown in
photo 14.
