Frequently Asked Questions
Which RC plane is this main landing gear spring for?
This is an FMS factory main landing gear spring designed for the FMS 1300mm PA-18 Super Cub's main gear, providing shock absorption during takeoff and landing.
What is the function of the main landing gear spring?
The spring absorbs landing impact forces to protect the airframe structure and ensures smoother ground handling. Damage results in increased gear rigidity, affecting ground control.
How do I know when to replace the spring?
Replace when the spring shows visible deformation, breakage, or loss of elasticity (hard landings feel stiff). Inspect the spring condition regularly.
What should I note during installation?
Ensure the spring seats correctly into the mounting slots on the main gear strut, with both ends secured firmly. Test spring rebound by pressing the gear after installation.
Can I replace just one spring?
Replace both main gear springs as a pair to maintain consistent elasticity on both sides, preventing uneven ground handling.
