Hirobo HI0412292 SDX FZ-V YOKE rotor head yoke for SDX helicopters  [HI0412292]

Rotor yoke for SDX series

This RC-scale replacement yoke is intended for use in SDX series helicopter head assemblies where the FZ-V yoke configuration is required. It serves as a direct replacement element for the rotor head linkage, carrying cyclic and pitch forces within the head assembly and contributing to predictable control response when fitted correctly.

Installation notes: verify part alignment within the head assembly, confirm correct seating on the blade grip and bearing interfaces, and use the original or equivalent fasteners without over-torquing. During fitment check blade tracking and collective symmetry before a full flight test. The yoke is a serviceable component in routine maintenance and mid-season tuning.

Tuning role: this yoke affects control geometry and swash-to-blade transfer, so minor adjustments to pitch links or trim may be required after replacement. Use conservative adjustments and log changes to maintain consistent flight behaviour.
