Replacement 5mm Ball Connectors

Offered as a set of ten, these D5mm ball connectors are designed for general helicopter linkage maintenance and spare use. Each connector serves as a compact ball joint where a 5mm seating is specified.

Installation notes: place the ball into the matching ball cup or rod end sized for 5mm, tighten threaded connections to the linkrod with the correct thread engagement, and check for any play after fitting. Apply a suitable RC threadlocker on metal-to-metal threads when installing on rotating components.

Tuning and service role: the connectors act as replaceable pivot points between servo arms and swashplates or control horns, assisting in maintaining consistent travel and reducing slop in pitch and cyclic adjustments. Inspect parts regularly and replace any that show visible wear or excessive movement.

Yes. The ten-piece set is aimed at small-scale RC helicopters that require 5mm ball fittings in their control linkages.
Insert the ball into the matching cup or thread it into a rod end, ensure alignment with the control horn, secure the threaded connection, then confirm smooth movement through the full servo travel range.
Look for increased play, noticeable surface wear on the ball, or binding during servo deflection. Any of these indicate the connector should be replaced.
