Hirobo HI0304040 Lepton LEX SWM Lever Shaft replacement part  [HI0304040]

Lepton lever shaft for linkage

This lever shaft is presented as an RC-scale replacement part tied to the Lepton LEX SWM naming, intended for use in rotor head linkage assemblies where a compact shaft transfers motion between control arms. The description focuses on the component's role inside small helicopter control systems rather than broader claims about compatibility beyond the Lepton designation shown in the product name.

In practice this shaft serves as the pivot or connection element that helps transmit cyclic and collective inputs through the rotor head linkage. When replacing a worn shaft, check surrounding linkages and bearings for wear and ensure the part seats correctly in its linkage pockets; correct alignment affects control response and neutral trim.

For tuning and maintenance, treat this item as a direct replacement that restores mechanical integrity to an otherwise original linkage assembly. Inspect for straightness and smooth rotation in the linkage joints, then verify swashplate centring and control throws after installation to confirm the part is functioning as expected.
