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

Tail Shaft - Auto-Rotation Function Explained

The Hirobo HI0304023 is an aftermarket auto rotation shaft designed for the Lepton Lex helicopter family. It replaces the tail rotor auto-rotation component to reinstate expected tail behaviour when the original shaft is compromised.

The shaft transfers rotational motion within the tail assembly and couples with the tail control linkage. Routine inspection should include checks for axial free play, smooth rotational feel, and accurate alignment to guarantee reliable tail response under load.

Fitting notes: take off the tail assembly cover and inspect adjacent linkages and bearings for signs of wear before installing the replacement shaft. Reassemble with the original fasteners and set the tail to neutral centre. Conduct stepwise ground trims and subdued hover runs to confirm the auto-rotation action is smooth and unencumbered.
