Lepton SZM Replacement Feathering Spindle HI0304012 by Hirobo  [HI0304012]

Overview of the Lepton SZM feathering spindle

This part is an RC-scale feathering spindle intended for the Lepton SZM rotor head lineup, provided as a replacement for routine servicing and minor repairs.

The spindle's role is to secure blade pitch links and convey control inputs through the rotor head; a degraded spindle can cause poor blade tracking and reduce tuning precision.

Installation guidance: assess existing linkages and bearings, remove the rotor head when required, transfer usable components, and fit the new spindle following standard rotor head reassembly practices; check for unobstructed blade motion and perform a static track inspection before flying.

Tuning role: renewing the spindle can restore consistent blade response and streamline pitch adjustments, improving repeatability during bench tuning sessions and field checks.
