Replacement Bushing Set for Hirobo HI0404522 - Eagle/Freya/EX/SX  [HI0404522]

What the SX bushing set covers

This Hirobo HI0404522 bushing set supplies replacement bushings intended for maintenance across the Eagle, Freya, EX and SX series. The text outlines compatibility considerations, how bushings affect drivetrain and control linkage behavior, and practical installation pointers while avoiding unspecified materials or sizes.

Apply this kit when you detect play at pivots or rotating joints in helicopter assemblies; worn bushings allow movement that undermines control precision and replacing them returns nominal fit. Installation is standard: remove the worn assembly, check the fit of the new bushings against the originals, and reinstall taking care with alignment and hardware torque for your model.

In tuning terms, bushings are service parts rather than performance parts; correct fit helps sustain consistent control feel and cuts down on repeated trim tweaks during testing. Also inspect associated bearings and linkage hardware when completing the replacement to ensure a full correction of symptoms.
