Hirobo HI0414319 Collective Pitch Shaft for Eagle-3 E3  [HI0414319]

Service part: collective shaft for Eagle-3 E3

This collective pitch shaft is an RC-scale replacement part designed for Eagle-3 E3 rotorheads. It replaces the rotating link that transmits control inputs from the swashplate to the blade pitch mechanism when the original shaft develops wear or slack.

Installation guidance: ensure shaft alignment with the swashplate and blade grips, tighten grub screws and retaining hardware to the correct specification, and confirm the shaft rotates freely without binding before flight. Perform a bench verification of pitch range and neutral position after fitting to confirm correct linkage geometry.

Tuning impact: the collective shaft is key to pitch repeatability and the mechanical geometry of the control system; fitting a service-grade replacement reduces free play and helps preserve consistent collective response for hovering and manoeuvres. Also inspect adjacent bearings and linkages during replacement.
