Replacement Auto Rotation Case for Lepton LEX — Hirobo HI0304022  [HI0304022]

Lepton LEX replacement auto-rotation case

This is an RC-scale auto rotation case supplied as a direct replacement for the Lepton LEX series to remedy wear or damage. The case supports the autorotation function and interfaces with the Lepton LEX rotor assembly, being intended for maintenance and repair rather than performance upgrades.

Fitment checklist: confirm bearing alignment and mating surface contact, inspect fastener threads, and check for freeplay before flight. Use the correct hex driver and controlled torque to avoid distorting the case and compromising freewheeling during autorotation.

Workshop guidance: installing a new case can re-establish reliable autorotation engagement and correct rotor tolerances; examine surrounding linkages and bearings during the swap to maintain dependable operation in the field.
