Air systems
Remove the nose gear from the aircraft.
Using a Matchmaker or a receiver and your
transmitter, center the nose steering servo and
attach a heavy duty steering arm.
Bolt in the nose gear steering servo as shown
in the photo. Do not use the rubber mounts
and brass eyelets. Loctite the bolts.
While the nose gear is out, make sure there are
no kinks or bends in the air lines.
Check the security of all screws and C clamps
on the struts and retract units.
Option: If your nose and main gear were
attached to their mounting plates by wood
screws, you may opt to reattach them with cap
head bolts and blind nuts. If so, remove the
mains, drill and install blind nuts for all three
landing gear, and reinstall.
Once the nose gear is reinstalled, operate the
strut by hand and insure that the nose gear
door will close completely over the nose wheel
mud guard. If not, shim the retract unit with
washers or ply until the door closes.
It is recommended that you install your air
systems for doors, retracts, brakes and speed
brake on the removable board in the nose of
the aircraft. Remove the board, paint if
desired, and install servos and valves. Make
sure to allow clearance to the sides of the
board for the curvature of the nose section.
