SDX FZ-V 8mm Spherical Bush Ball - HI0412295 Hirobo  [HI0412295]

Precision 8mm spherical bush for SDX FZ-V

This 8mm spherical bush ball is a compact linkage component catalogued as Hirobo HI0412295, made for SDX FZ-V helicopter control linkages where a small ball joint is required. It forms a pivoting connection between control rods and control horns to preserve alignment and reduce lateral slop in cyclic and tail linkages.

Fitment is straightforward for experienced model technicians: seat the ball into the matching socket, confirm correct linkage orientation to avoid binding, and secure any retaining hardware to the recommended torque. Verify full, free movement through the intended travel and re-check fastener tightness after a short test hover.

As a tuning item, this spherical bush ball sharpens control feedback by cutting unwanted play at the joint; pairing it with correctly adjusted pushrods and a well-trimmed swash or servos improves precision. Inspect regularly for wear and replace when noticeable play appears to maintain consistent handling.
