Installation
1. Use a 2mm hex wrench to remove the pair of setscrews retaining the strut in each main gear trunnion. Apply threadlock to the setscrews and reinstall them.
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. You will find the main units require the use of a 100-degree countersunk woodscrew while the nose unit requires a button head woodscrew.
Nosegear Steering
Connect the steering pushrod clevis to the steering arm on the nosegear.
