RC Helicopter D5mm Ball Connector Set, 10 pcs - Hirobo HI2525011  [HI2525011]

Helicopter D5mm Ball Joints

This product is a 10-piece set of D5mm ball connectors intended for standard helicopter maintenance and linkage spare use. The parts operate as small ball joints in control linkages requiring a 5mm ball seating.

Installation notes: seat the ball into the matching ball cup or rod end sized for 5mm, secure threaded connections with the recommended engagement, and confirm there is no unwanted free play. When fitting to rotating hardware, apply an RC-safe threadlocker on metal-to-metal threads as needed.

Tuning and service role: these ball connectors act as replaceable pivots between servo output arms and swashplates or control horns, assisting in consistent travel and helping to reduce slop in pitch and cyclic settings. Replace any piece showing visible deformation or excessive movement.
