Hirobo HI0304012 Lepton SZM Feathering Spindle  [HI0304012]

Feathering spindle for Lepton SZM

This is an RC-scale feathering spindle intended for the Lepton SZM series rotor head, provided as a direct replacement component for routine maintenance and small repairs.

The spindle plays a focused role in the rotor head assembly by securing blade pitch links and transferring control inputs; when worn or damaged it can affect blade tracking and feel during tuning.

Installation guidance: inspect existing linkage and bearings, remove the rotor head as needed, transfer any serviceable parts, and fit the spindle following standard rotor head reassembly practice; verify free blade movement and perform a static tracking check before flight.

Tuning role: replacing the spindle can restore consistent blade motion and simplify pitch adjustments, helping with repeatable rotor setup during bench tuning sessions and field maintenance.
