Hirobo Eagle/Freya/EX/SX Collective Pitch Lever Shaft HI0404624  [HI0404624]

Replacement 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 functions as the rotating pivot in the collective pitch linkage, transmitting cyclic and collective inputs between the swashplate and the blade control arms.

Compatibility: verify the part number HI0404624 against your helicopter parts diagram before ordering, since fitment is specific to the Eagle, Freya, EX and SX platform families. This component is a routinely stocked spare for those model lines and is fitted when the original lever shaft develops wear or free play.

Installation notes: remove the main rotor hub and secure the airframe before replacing the shaft. Check linkage alignment and confirm the swashplate moves freely through the full range of collective travel after installation. Reuse original retaining hardware where applicable and inspect adjacent bearings and linkages for wear while the assembly is open.

Tuning role: though small, the lever shaft influences collective symmetry and pitch consistency; any shaft wear or looseness can cause uneven pitch response, so replacing this part is a common maintenance step when diagnosing inconsistent collective behavior.
