Helpful hints to ensure your gear last longer.
- Avoid actuating while model is sitting on its landing gear as this will cause the gear to strip.
- Make sure nothing is causing binding in path of landing gear, failure to do so may cause permanent damage to gear.
- Allow gear to fully cycle up or down before hitting switch. Quickly changing direction up/down/up/down in rapid succession without allowing gear to finish cycling fully up or down may cause damage to gear.
- Add removable thread locker to all set screws that hold axle/strut together.
- Best practice is to file flat spot where screws hold axles onto struts.
