SRB Helicopter Tail Drive Shaft (Carbon) HI0302013 HIROBO  [HI0302013]

Details on the SRB tail carbon shaft

This carbon tail drive shaft serves as a replacement part for SRB series helicopter tail drive systems at the model RC level. It transmits rotation from the main tail output to the tail rotor gearbox while offering a stiffer, lighter alternative to some metal shafts to reduce torsional flex under load.

Installation notes: before installing, check the tail boom and support bearings for wear, confirm spline engagement and straightness, and ensure the shaft runs true through the boom. Tighten retaining hardware per the manufacturer's torque guidance and carry out a short hover test to confirm alignment. This description refers to model-level RC use only.

Tuning role: when used during a tail drive overhaul, a carbon shaft can deliver crisper tail response and better hold by cutting drive lash and deflection; pairing this with bearing replacement and linkage adjustment will optimise yaw control.
