Tail Drive Guide 32-BL HIROBO HI0402366  [HI0402366]

Overview of tail drive function

This HIROBO HI0402366 unit functions as a purpose-made RC tail drive guide to organise the routing and alignment of the tail drive within helicopter shuttle assemblies. It acts as a stabilising point so the tail shaft or belt remains aligned along the fuselage, limiting sideways movement and supporting consistent tail rotor performance both in the air and on the bench.

Best practice for installation is to place the guide into the existing drive route without forcing the shaft or belt. Confirm axial alignment and smooth movement after fitting, ensure it does not bind at any collective or yaw position, and check clearances to the tail boom and adjacent linkages. Mount using the original helicopter frame points and secure with the correct fasteners supplied.

For tuning and upkeep, the guide helps maintain tail drive tension and routing stability, which supports predictable tail reactions when changing pitch curves, yaw gains, or gyro parameters. Regular checks for wear and correct seating are advised to avoid wobble and premature wear on other parts.
