Hirobo HI0412292 SDX FZ-V Head Yoke Replacement  [HI0412292]

SDX series FZ-V yoke replacement

This replacement yoke is designed for SDX series helicopter head assemblies using the FZ-V design. It replaces the rotor head linkage part that transmits cyclic and pitch forces, helping to restore consistent control feel when properly installed.

Installation notes: check part orientation and seating at the blade grip and bearing interfaces, and use correct fasteners to avoid distortion. After fitting, inspect blade tracking and swash symmetry before conducting a flight. The yoke is intended for routine service and periodic tuning tasks.

Tuning role: because the yoke affects swash-to-blade transfer, expect small changes in control response; adjust pitch links and trims incrementally and document each change to keep flight characteristics predictable.
