Hirobo HI0304045 Lepton Lex tail pulley 14T replacement part  [HI0304045]

Lepton Lex tail pulley (14T)

This is an RC-scale tail pulley designed for the Hirobo Lepton Lex series, presented as a 14T replacement component for the tail rotor drivetrain. It is intended as a direct swap when the existing pulley shows wear or damaged teeth, restoring engagement for the tail drive system without altering the main rotor or control geometry.

Installers should confirm tooth count and alignment before mounting, inspect mating gears or belts for wear, and ensure the pulley seats flush on the tail shaft. In service, monitor for uneven wear or chipped teeth and replace the pulley if movement or play is detected to keep tail responsiveness predictable during tuning and flight testing.
