Lepton Tail Drive Shaft for Lepton - HI0304044 Hirobo  [HI0304044]

Tail shaft functions for Lepton

The HI0304044 tail shaft is a replacement part made for Lepton-series Hirobo helicopters, acting as the core member in the tail drive train. It conveys rotational force toward the tail rotor while helping to keep the main drive and tail rotor aligned.

Installation notes: inspect the surrounding bearings and linkages for wear prior to installation, confirm the shaft seats correctly in the tail case and that splines engage cleanly without forcing, then recheck tail pitch and tracking after assembly. Apply thread-lock where specified and tighten fasteners to the torque values in the aircraft manual.

Tuning role: shaft straightness and fit affect drivetrain runout and tail responsiveness; installing the shaft correctly reduces vibration and simplifies final servo and linkage adjustments.
