Eagle Freya Compatible FFZ-2 Spindle Holder - Hirobo HI0414103  [HI0414103]

Compatibility and Fit for the Freya FFZ-2 Holder

This HI0414103 spindle holder by Hirobo is a machined alloy replacement designed for Freya FFZ-2 rotor assemblies. It locates and supports the rotor spindle within the head assembly to maintain stable blade pitch response and accurate rotor tracking.

The component is compatible with Eagle Freya series airframes that use the FFZ-2 spindle layout; confirm the head block and mounting holes match your model before fitting. The item is supplied as a direct replacement or spare part rather than a high-performance enhancement.

Fitting advice: check bearing condition and mating surfaces for wear or contamination, align the spindle squarely to avoid side loading on bearings, and tighten fixings evenly without excess torque. Once fitted, inspect rotor runout and pitch symmetry as part of standard setup and tuning.
