Hirobo HI0301022 XRB M4 Rod End  [HI0301022]

Rod end for XRB helicopters

This rod end is an RC-scale replacement part designed for XRB series helicopter assemblies, identified by Hirobo model HI0301022. It serves as a compact linkage terminal that interfaces with threaded M4 linkages commonly found in XRB component layouts, providing a direct mechanical connection point for control linkages on model helicopters.

Installation is straightforward for hobbyists familiar with model helicopter maintenance: remove the worn or damaged rod end, thread the HI0301022 onto the matching M4 linkage, and secure any retaining hardware originally used on your airframe. The part is intended to integrate with existing XRB series linkage geometry without requiring modification to surrounding components.

In tuning and setup, use the rod end to restore correct linkage length and articulation after wear or impact. It is a practical service item for routine maintenance and quick field repairs where restoring reliable mechanical linkage movement matters more than aesthetic concerns.
