Hirobo HI0304044 Lepton Lex Tail Shaft  [HI0304044]

Lepton tail shaft overview

This tail shaft is an RC-scale replacement part intended for Lepton-series Hirobo helicopters. It serves as the core link in the tail drive assembly, transferring drive motion toward the tail rotor and helping maintain alignment between the main drive and tail rotor system.

Installation notes: inspect the surrounding bearings and linkage for wear before fitting the shaft, ensure correct seating in the tail case and verify spline engagement without forcing components, and recheck tail pitch and tracking after reassembly. Use appropriate thread-lock and torque values for fasteners specified by your helicopter's manual.

Tuning role: the tail shaft affects drivetrain runout and tail responsiveness; a correctly fitted shaft supports consistent tail rotor behavior, reduces vibration sources, and simplifies subsequent servo and linkage trimming.
