Replacement Collective Pitch Shaft HI0414319 compatible with Eagle-3 E3 by Hirobo  [HI0414319]

Collective pitch replacement for Eagle-3 E3

This collective pitch shaft is supplied as a service replacement for Eagle-3 E3 rotorheads. It is used in place of the rotating link that conveys pilot input from the swashplate to the blade pitch control when the original shows wear or excessive play.

Fit notes: confirm alignment to the swashplate and blade grips, tighten grub screws and retainers securely, and make sure the shaft spins freely without any binding before attempting flight. A brief bench check of neutral position and pitch endpoints following installation will help ensure correct linkage geometry.

Why it matters: the collective pitch shaft contributes directly to pitch repeatability and overall linkage geometry. Fitting a correctly aligned replacement reduces free play and supports predictable collective response. Inspect surrounding bearings and linkages when carrying out the swap to maintain control fidelity.
