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

Linkage cross member for RC helicopters

This Hirobo cross member is a model-scale component designed to secure linkage connections where a 5mm ball interface pairs with an M2 x 20 fastener. It functions as a short structural connector between control rods and ball studs, helping preserve alignment in collective and tail link setups.

To install, align the ball joint with the mating linkage, pass the M2 x 20 fastener through the mount, and tighten into the existing threaded point. Confirm the ball is seated and that the joint moves freely before completing the installation to avoid any binding during rotor rotation.

During setup and trimming, this cross member will influence control geometry and any play at the ball joint; check servo neutral travel and linkage clearance to ensure predictable response. This part is intended for model helicopters and related small rotorcraft assemblies only.
