Hirobo HI0404522 SX Bushing Kit for Eagle/Freya/EX  [HI0404522]

Bushing kit details for SX and siblings

This Hirobo HI0404522 bushing kit provides replacement bushings designed for maintenance on Eagle, Freya, EX and SX platforms. The passage focuses on compatibility guidance, the function of bushings in drive and control linkages, and straightforward installation tips without stating unspecified measurements or materials.

Fit this set when inspecting for looseness at pivot points and rotating joints; worn bushings can introduce play that affects control precision, and fresh bushings restore nominal fit. Installation is typical RC maintenance: disassemble the affected area, match old parts to the new bushings to ensure fit, and reassemble while keeping alignment and fastener torque in mind for your model.

From a tuning standpoint, bushings are a maintenance necessity rather than a performance upgrade; ensuring proper fit maintains consistent control response and reduces the frequency of trim adjustments during test flights. Also check adjacent components such as bearings and linkage ends to ensure the repair addresses all wear sources.
