Hirobo HI0412292 Replacement Yoke for SDX Helicopter Heads  [HI0412292]

Aftermarket yoke suited to SDX heads

This replacement yoke fits SDX series helicopter head assemblies that use the FZ-V configuration. It replaces the rotor head linkage element, carrying cyclic and pitch forces and aiding in predictable control response when correctly installed.

Installation notes: ensure correct alignment within the head assembly, check the yoke seats on blade grip and bearing contact points, and refit using correct fasteners without excessive torque. After install, check blade tracking and collective symmetry before any flight. The yoke is intended for routine servicing and tuning updates.

Tuning role: changing the yoke will affect control geometry and swash-to-blade transfer, so allow for small trim and pitch-link adjustments. Make conservative changes and log them to keep handling consistent.
