PHS 3EC Replacement Rod End HI2500113 Compatible with Hirobo Helicopters  [HI2500113]

Compact pivot for swashplate and control rods

The Hirobo HI2500113 rod end serves as a small but critical linkage part for helicopter control assemblies. Supplied singly, it links control rods to swashplate arms, servo outputs, or tail linkage points where a compact spherical pivot is required. The PHS 3EC marking identifies this exact variant in Hirobo's parts range.

When fitting this rod end, ensure the internal thread matches your control rod or ball stud and verify correct thread engagement. Apply threadlocker only when appropriate for the installation and avoid overtightening to maintain smooth articulation. Regular checks for wear and endplay will help preserve reliable control response.

For setup and tuning, note that this rod end affects linkage geometry and play. Swapping out tired rod ends can tighten up the control chain and improve servo feedback, though final handling depends on the whole linkage system including clevises and servo arms.
