M2 x 20 Cross Member with 5mm Ball Joint for RC Helicopters - Hirobo HI2511013  [HI2511013]

Precision cross link for rotorcraft controls

This Hirobo cross member is crafted for model helicopter link assemblies where a 5mm ball joins to an M2 x 20 fastening point. It acts as a compact connector between pushrods and ball studs to help keep control link geometry aligned.

Installation generally requires aligning the ball joint to the corresponding linkage, inserting the M2 x 20 screw through the mount, and securing it into the mating threaded hole. Verify freedom of movement at the ball before making final adjustments so the linkage does not bind during rotor operation.

When tuning, the cross member will alter linkage geometry and any play at the ball joint; recheck servo neutral positions and control throws after fitting to maintain consistent handling. This component is intended for model-scale helicopters and similar small rotorcraft hardware only.
