Replacement Auto-Rotation Clutch for Hirobo Eagle/Freya/EX/SX - HI0404565  [HI0404565]

HI0404565 clutch description

The Hirobo HI0404565 auto-rotation clutch is an aftermarket spare part designed for shared clutch assemblies on several Hirobo helicopter ranges. It provides the mechanical interface that allows the rotor to disengage and later re-engage under autorotation conditions, aiding controlled spin-down and restart.

Offered as a direct replacement for the Hirobo models noted, always cross-check HI0404565 with your rotor hub and clutch housing entries before disassembly to ensure the correct component is fitted.

Fitment follows standard field maintenance steps: remove canopy and rotor head components to access the clutch stack, install the replacement element, then reassemble and carry out bench testing to fine-tune engagement timing and verify smooth rotor transitions.

Compatibility

Built as a common replacement for Hirobo Eagle, Freya, EX and SX platforms; confirm HI0404565 against your airframe parts list to guarantee fitment.

Install HI0404565 to restore consistent autorotation response and rotor engagement on supported Hirobo helis; careful bench adjustment will optimise performance for training flights.
