2. Test t the retract unit in the wing or fuselage to determine
the strut length and axle location. Cut the strut to length using
a cutoff wheel in a rotary tool.
3. Make two at spots on the end of the strut with a le and
use a 2.5mm hex wrench to secure the axle to the strut. Apply
threadlock to the threads of the retaining screws so they do
not loosen from vibration.
4. Install the wheels on the axles. Slide the brass wheel collar
onto the axle and secure it using a 1.5mm hex wrench. Apply
threadlock to the setscrew to prevent it loosening due to
vibration.

a pencil and drill appropriately sized holes for the hardware
you intend to use.

of a 100-degree countersunk woodscrew while the nose unit
requires a button head woodscrew.
