Hirobo HI0414103 Freya FFZ-2 Rotor Spindle Holder (compatible with Eagle Freya)  [HI0414103]

Product Brief: Freya FFZ-2 Spindle Holder

This is a replacement spindle holder for the Freya FFZ-2 rotor assembly by Hirobo, reference HI0414103. The precision-machined alloy part secures the rotor spindle in the head assembly and helps preserve consistent blade pitch response.

Compatibility is aimed at Eagle Freya series airframes that employ the FFZ-2 spindle arrangement; confirm the match with your head block prior to installation. The component is intended as a service part or spare rather than an aftermarket performance enhancement.

Fitment guidance: inspect bearing races and mating faces for contaminant or wear, position the spindle squarely and avoid introducing side load, and torque fasteners in small, even increments. After installation, verify rotor runout and pitch balance as part of your setup routine.
