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

Direct-fit collective shaft for Eagle-3 E3

This replacement collective pitch shaft is an RC-scale service part intended for Eagle-3 E3 rotorheads. It serves as a direct replacement for the rotating link that transmits pilot input from the swashplate to the blade pitch mechanism, and is used when the original shaft shows wear or play.

Fit and installation: check alignment with the swashplate and blade grips, verify grub screws and retaining hardware are secure, and confirm free rotation without binding before flight. A quick bench check of pitch range and neutral position after installation helps ensure correct linkage geometry.

Tuning role: the collective pitch shaft affects pitch repeatability and mechanical link geometry; a correctly fitted shaft reduces free play and supports consistent collective response during hover and manoeuvres. Inspect surrounding bearings and linkages when replacing to maintain overall control fidelity.
