32-BL Tail Drive Guide HIROBO HI0402366  [HI0402366]

Tail drive guide summary

This HIROBO HI0402366 guide is an RC-scale tail drive routing aid designed to control the alignment of the tail drive inside helicopter shuttle assemblies. It provides a guidance point so the tail shaft or belt tracks cleanly through the fuselage, reducing sideways play and contributing to consistent tail rotor behaviour in both flight and bench testing.

For correct installation, align the guide within the existing tail drive route without forcing the shaft or belt. After fitting, check axial alignment and ensure smooth free movement across the full range of collective and yaw positions, and confirm there is adequate clearance to the tail boom and adjacent linkages. Fit the guide to the original mounting points and use the recommended fasteners.

When tuning and servicing, the guide helps maintain even drive tension and tidy routing, which supports predictable tail performance when altering pitch curves, yaw gains, or gyro parameters. Regular inspection for wear and correct seating will reduce the chance of drive wobble and premature component failure.
