16. Use a flat file to make a 1/4-inch (6mm) wide
flat area on the gear near the end of the axle strut
for the setscrew to rest. This will keep the wheel
collar from vibrating loose in flight.
Always use threadlock on metal-to-metal fasteners
to prevent them from vibrating loose.
17. Slide a 3.5mm aluminum wheel spacer on
the axle, then the wheel with adapters. A 3.5mm
wheel collar is used to secure the wheel in position
by tightening the setscrews onto the axle using a
1.5mm hex wrench.
The end of the axles may have a slight bur
on them from the factory. If the wheel is hard
to install use a file to remove this bur.
18. Check to make sure the axle is flush with the
edge of the outer wheel collar. If not, use a rotary
tool and cutoff wheel to trim the axle flush with the
wheel collar. Make sure to remove the wheel so the
heat generated from the cutting does not melt the
bushings in the wheel.
19. Check the operation of the retract using the
radio system. The wheel will retract into the center
of the wheel well. If not, slightly bend the strut so
it does.
20. Repeat steps 1 through 19 to install the
remaining main landing gear and wheel.
