Lepton Lex 14T Tail Pulley Replacement HI0304045 by Hirobo  [HI0304045]

Lepton Lex 14T Tail Pulley Overview

This is an RC-scale tail pulley designed for the Hirobo Lepton Lex series, supplied as a 14T replacement component for the tail rotor drivetrain. It fits as a direct swap when the existing pulley has worn or damaged teeth, restoring positive engagement for the tail drive without altering main rotor alignment or control geometry.

Before installation confirm the 14T tooth count and correct alignment, inspect mating gears or belts for signs of wear, and ensure the pulley seats flush on the tail shaft. In service monitor for uneven wear, chipped teeth, or any play and replace the pulley if movement is detected to keep tail response predictable during tuning and flight testing.
