Hirobo HI0414103 Freya FFZ-2 Spindle Holder  [HI0414103]

Freya FFZ-2 Spindle Holder Overview

This is an RC-scale spindle holder designed for the Freya FFZ-2 rotor assembly from Hirobo, identified as HI0414103. It serves as the mounting point for the rotor spindle and locates the spindle within the head assembly, contributing to consistent blade pitch response and rotor tracking.

Compatibility is limited to Eagle Freya series airframes that use the FFZ-2 spindle arrangement; confirm fit against your existing head block before installation. The part is intended as a direct replacement or spare for model maintenance rather than a performance upgrade component.

Installation notes: inspect mating surfaces and bearings for wear, align the spindle carefully in the holder to avoid side load on the rotor bearings, and secure fasteners without over-torquing to prevent distortion. After fitting, check rotor runout and pitch symmetry as part of normal setup and tuning procedures.
