threadlock to the setscrews and reinstall them.
25- to 46-Size Electric Retract Instructions
2. Test fit 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 flat spots on the end of the strut with a file 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.
5. Mark the retract mounting hole locations on the rails using a
pencil and drill appropriately sized holes for the hardware you
intend to use.
6. Install the retracts in the model using the screws provided
with the kit or those of your own choice. A #4 x 1/2-inch
wood screw works well.
