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

Overview of SX and related model bushings

This Hirobo bushing set contains replacement bushings intended for routine maintenance on the Eagle, Freya, EX and SX helicopter families. The text highlights compatibility notes, the role bushings play in drivetrain and control linkages, and practical installation considerations without listing unprovided dimensions or materials.

Use this kit when you find wear at pivot points and rotating joints in RC helicopter assemblies; replacing worn bushings restores correct fit and reduces slop that can degrade flight feel and control precision. Installation follows standard RC maintenance: remove the affected assembly, compare old parts with the new bushings to confirm fit, and reinstall while observing alignment and retaining hardware torque appropriate to your airframe.

For setup and test flights, bushings are a maintenance item rather than a performance upgrade; correct fit helps maintain consistent control response and reduces the need for repeated trim corrections. Inspect related parts like bearings and linkages when replacing bushings so the repair addresses all sources of play.
