PHS 3EC HI2500113 Rod End for Hirobo Helicopter Linkages  [HI2500113]

Small pivot joint for rotorcraft linkages

The Hirobo HI2500113 rod end is an RC linkage part used in helicopter control assemblies. It is supplied individually and is intended to join control rods to swashplate arms, servo outputs, or tail linkage points where a compact pivoting connection is needed. The PHS 3EC code identifies this specific variant.

Installation requires matching the internal thread to your control rod or threaded stud. Hand-start the thread, confirm full engagement and correct endplay, then secure using the appropriate locknut or light threadlocker. Avoid overtightening to retain smooth pivot action and check periodically for wear.

As part of tuning, this rod end will affect linkage geometry and overall play. Replacing worn rod ends can remove unwanted slop and help achieve a more precise servo response, but optimal control depends on the condition of the entire linkage assembly.
