XRB Control Rod End M4 Upgrade HI0301022 for Hirobo  [HI0301022]

Replacement rod end tailored to XRB helicopters

This component is an RC-scale replacement rod end intended for XRB series helicopter assemblies and is listed as Hirobo model HI0301022. It functions as a compact terminal that mates with threaded M4 linkages used in XRB layouts, delivering a direct mechanical connection for model helicopter controls.

Installation is simple for those familiar with helicopter maintenance: detach the damaged rod end, thread the HI0301022 onto the matching M4 pushrod, and secure any original retaining hardware. The part is designed to fit into existing XRB linkage geometry with no modifications to surrounding parts.

For setup and tuning, use the rod end to re-establish correct linkage length and articulation following wear or impacts. It is a useful service spare for routine maintenance and prompt field repairs where restoring dependable linkage motion is the priority.
