Lepton Lex Auto Rotation Shaft - Tail Rotor Auto-Rotation Replacement HI0304023 by Hirobo  [HI0304023]

Lepton Lex Tail Auto-Rotation Shaft Overview

This Hirobo HI0304023 replacement part is an RC-scale auto rotation shaft intended for the Lepton Lex helicopter family. It functions as a direct replacement for the tail rotor auto-rotation mechanism and helps return worn or damaged tails to expected behaviour.

The shaft transmits rotational motion through the tail assembly and links directly with the tail control linkage. When evaluating the tail system, inspect for axial play, ensure smooth rotation, and confirm correct alignment before and after fitment to secure predictable tail behaviour.

Installation notes: remove the tail assembly cover and check adjacent linkages and bearings for wear before installing the new shaft. Refit with the original fasteners and confirm tail-centre neutral alignment. After fitting, carry out short-range tuning and gentle hover checks to verify consistent auto-rotation action and freedom from binding.
