location and enlarge the hole to the diameter of the fi ll valve
using a drill bit or a reaming tool (recommended method).
❏
17. Sand the inside of the fuselage around the hole you
just made. Clean the area using denatured alcohol. Glue the
included plywood disk over the hole on the inside of the fuselage.

18. Insert the fi ll valve through the hole and secure it in
place using the jam nuts and thread locking compound.

19. Connect the remainder of the air lines to the air tank,
fi ll valve and air valve. T-fi ttings will also be needed to join the
components together (see the instructions that came with
your retracts). Attach quick disconnects to the lines that will
connect to the main gear.

axle to 1" [25mm] long as shown in the photo. Grind a fl at spot
at the end of the axle for the wheel collar set screw.

[4mm] wheel collar, 6-32 set screw and thread locking
compound. A drop or two of oil on the axle will ensure that
the wheel rotates freely. Loosely thread a 6-32 x 1/4" [6mm]
SHCS into the axle. Slide the axle onto the end of the nose
gear strut and move the retract to the locked up position.
Position the axle on the strut so that the wheel is as far aft as
possible but still moves up and down without contacting the

position. Rotate the axle on the wire so the nose wheel will
