Hirobo XRB EX M4 Ball Link HI0301023  [HI0301023]

XRB EX M4 Ball Link Details

This is an RC-scale replacement ball link listed among Hirobo XRB components and intended for XRB EX series linkage assemblies. The spare carries the designation HI0301023 and is used to maintain or restore ball-end linkage performance on scale models.

Install the link as a direct replacement: remove the damaged part, confirm the M4 thread matches the receiving control horn or pushrod, and secure the joint ensuring free articulation with no lateral play. Avoid forcing mismatched parts and recheck full travel for smooth operation after fitting.

In terms of setup, exchanging ball links affects servo-to-linkage geometry and control feel. Fit HI0301023 when you need to restore factory linkage geometry and consistent, repeatable control response.
