Hirobo HI0404744 80 degree Damper Rubber for Eagle/Freya/EX/SX  [HI0404744]

Hirobo damper rubber specification and fit

This damper rubber by Hirobo matches the common damper mounts found on Eagle, Freya, EX and SX helicopter models. The 80 degree rubber compound provides the designed geometry for angled damper cushions that reduce vibration transfer through the mount.

Install as a direct replacement for fatigued or hardened rubbers to return original damping characteristics. The element operates between the damper housing and the airframe or landing gear attachment to absorb impulsive forces and help stabilise rotor and airframe interaction during hover and manoeuvres.

Maintain the 80 degree type when replacing to preserve baseline compliance so spring preload and oil viscosity adjustments remain predictable in tuning sessions.
