Hirobo HI0404624 Collective Pitch Lever Shaft for Eagle/Freya/EX/SX series RC helicopters  [HI0404624]

Collective pitch lever shaft

This is an RC-scale collective pitch lever shaft intended as a direct replacement part for Hirobo Eagle family helicopters and related models listed under common Eagle parts. The shaft serves as the rotating pivot in the collective pitch linkage, transmitting cyclic and collective inputs between the swashplate and the blade control arms.

Compatibility: check that the part number matches your helicopter's parts list before ordering, as fitment is specific to Eagle, Freya, EX and SX platform families. This component is a common spare in those model lines and is used where the original lever shaft shows wear or play.

Installation notes: remove the main rotor hub and secure the airframe before replacing the shaft, verify linkage alignment and free movement of the swashplate after installation, and confirm there is no binding throughout the collective travel. Use the original retaining hardware where provided and inspect surrounding bearings and linkages for wear while the assembly is disassembled.

Tuning role: the lever shaft is a small mechanical element but it affects collective symmetry and pitch consistency; any shaft wear or looseness can introduce uneven pitch response, so replacement is a standard step during maintenance when diagnosing inconsistent collective behavior.
