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

Auto-Rotation Tail Shaft for Lepton Lex

The Hirobo HI0304023 is an RC auto rotation shaft made for the Lepton Lex helicopter series. It is intended as a replacement for the tail rotor auto-rotation assembly to recover correct tail performance after wear or damage.

Its role is to transmit rotational drive within the tail assembly and to interface with the tail control linkage. During routine checks, examine for axial play, verify smooth rotation through the bearings, and ensure alignment remains correct both before and after fitting to avoid unpredictable tail behaviour.

Fitment instructions: remove the tail cover and inspect nearby linkages and bearings for wear prior to installing the replacement shaft. Use the original fasteners when reassembling and set the tail to neutral centre. Complete careful ground trims and gentle hover validation to ensure the auto-rotation mechanism operates freely and consistently.
