SDX FZ-V Rotor Head Yoke HI0412292 by Hirobo  [HI0412292]

Service replacement yoke for SDX heads

This RC-scale replacement yoke is made for use in SDX series helicopter head assemblies that require the FZ-V yoke configuration. It functions as a direct swap for the rotor head linkage, transmitting cyclic and pitch loads through the head assembly and helping to restore predictable control response when installed correctly.

Installation notes: confirm correct alignment in the head assembly, ensure the yoke seats properly on the blade grip and bearing faces, and refit using the original or equivalent fasteners without over-torquing. After installation, verify blade tracking and collective symmetry before attempting a full flight test. This yoke is intended as a serviceable item for routine maintenance and mid-season adjustments.

Tuning role: the replacement yoke influences control geometry and swash-to-blade transfer, so expect small changes in feel and possible minor adjustments to pitch links or trims. Make measured adjustments and record changes to maintain consistent flight behavior.
