Feathering Spindle Compatible with Lepton SZM HI0304012 by Hirobo  [HI0304012]

Lepton SZM spindle function summary

This RC-scale feathering spindle is designed for the Lepton SZM rotor head series and is supplied as a replacement for ongoing maintenance and light repairs.

The component secures pitch link connections and transfers control inputs through the rotor head; when the spindle wears it can upset blade tracking and detract from tuning accuracy.

Installation guidance: inspect linkages and bearings before disassembly, remove the rotor head if necessary, re-use serviceable parts, and install the spindle using common rotor head reassembly methods; verify free blade rotation and carry out a static tracking procedure prior to flight.

Tuning role: installing a new spindle can stabilise blade movement and simplify pitch trimming, delivering more consistent results during bench tuning and field adjustments.
