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

SX bushing set essentials

This Hirobo HI0404522 bushing set provides replacement bushings intended for maintenance on Eagle, Freya, EX and SX platforms. The description covers compatibility notes, the importance of bushings in drivetrain and control linkage function, and straightforward installation advice without specifying unstated dimensions or material details.

Fit this kit if you find wear at pivot points or rotating joints; worn bushings allow excess movement that impairs flight feel, and renewing them restores correct fit. Installation follows typical RC maintenance practice: remove the affected assembly, verify the new bushings match the originals, and reinstall with attention to alignment and fastener torque suited to your airframe.

From a tuning perspective, bushings are maintenance items rather than performance modifications; correct fit keeps control inputs stable and reduces repeated trim corrections in flight testing. Also check adjacent components such as bearings and linkage ends to ensure the replacement resolves the root cause of any play.
