Hirobo HI0404522 SX bushing set for Eagle/Freya/EX/SX series  [HI0404522]

SX bushing set overview

This Hirobo bushing set supplies replacement bushings intended for RC helicopter maintenance and parts refresh on platforms listed as common Eagle/Freya/EX/SX components. The article focuses on compatibility notes, the role of bushings in drivetrain and control linkages, and practical installation considerations without specifying unlisted dimensions or materials.

Use this set when inspecting wear at pivot points and rotating joints in RC helicopter assemblies; replacing worn bushings restores nominal fit and reduces slop that affects flight feel and control precision. Installation is standard RC-scale maintenance: remove the affected assembly, compare old parts to the new bushings for fit, and reinstall with attention to alignment and retaining hardware torque appropriate for your airframe.

For tuning, bushings are a maintenance item rather than a performance upgrade; ensuring correct fit helps maintain consistent control response and reduces the need for repeated trim changes during test flights. Check associated components like bearings and linkages for wear when replacing bushings to ensure a complete corrective action.
