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

Lepton Lex Auto Rotation Shaft

This Hirobo replacement part is an RC-scale auto rotation shaft intended for the Lepton Lex helicopter family. It serves as a direct replacement component for the tail rotor auto-rotation mechanism, restoring intended tail response when worn or damaged.

The shaft's role is mechanical and functional: it transmits rotational motion within the tail assembly and interfaces with the tail control linkage. When inspecting the tail system, check for axial play, smooth rotation, and correct alignment before and after fitment to ensure predictable tail behaviour.

Installation notes: remove the tail assembly cover and inspect adjoining linkages and bearings for wear prior to fitting the new shaft, reassemble with original fasteners and verify tail-centre alignment at neutral. After installation, perform ground-range tuning and low-power hover checks to confirm the auto-rotation action is consistent and free from binding.
