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

Replacement Shaft for Lepton Lex Aircraft

The Hirobo HI0304023 is an RC-scale auto rotation shaft for the Lepton Lex helicopter range. It serves as a replacement element for the tail rotor auto-rotation assembly, bringing back intended tail response when the original part shows wear.

Functionally, the shaft carries rotational force within the tail assembly and interfaces with the tail control linkage. During inspection, look for axial play, check for smooth bearing action, and confirm correct alignment both before and after fitting to maintain stable tail performance.

Installation guidance: remove the tail cover to inspect adjoining linkages and bearings for deterioration before fitting the new shaft. Reassemble using the original fasteners and verify that the tail rests at neutral centre. Complete ground-range trims and cautious low-power hover checks to ensure the auto-rotation mechanism operates smoothly.
