Hirobo HI2511013 M2 x 20 Cross Member with 5mm Ball Adapter for RC Helicopter Linkages  [HI2511013]

Sturdy control link connector for models

This Hirobo cross member is intended for model helicopter linkages that require a 5mm ball interface combined with an M2 x 20 fastening solution. It provides a short, rigid link between control rods and ball studs to maintain alignment in control systems.

To fit the unit, line up the ball joint with the mating linkage, insert the M2 x 20 screw into the mount, and fasten into the existing threaded boss. Confirm that the ball moves freely after tightening to prevent any interference during rotor rotation.

In setup and tuning scenarios, the part will influence linkage geometry and any residual play at the ball joint; verify servo centering and travel limits after installation to keep control inputs predictable. This product is designed for model helicopters and small rotorcraft use only.
