HIROBO HI0302013 Carbon Tail Drive Shaft for SRB Helicopters  [HI0302013]

Tail drive shaft — SRB carbon replacement

This carbon tail drive shaft is an RC replacement intended for SRB series helicopter tail drive systems. It connects the main tail output to the tail rotor gearbox and provides a stiffer, lighter alternative to many metal shafts to help limit torsional flex during operation.

Installation notes: inspect the tail boom and support bearings for wear before fitting, verify spline engagement and overall straightness, and confirm the shaft runs true through the boom. Tighten retaining hardware to the manufacturer's recommended torque and perform a short hover to check alignment. This description refers to model-level RC use only.

Maintenance and tuning: as part of a tail drive refresh, fitting a carbon shaft can improve tail hold by reducing drive lash and deflection; combine this upgrade with gearbox servicing, linkage checks, and bearing replacements to maintain consistent yaw control.
