EMBLA SZM2 Linkage Radius Block - Hirobo HI0304118  [HI0304118]

Brief: EMBLA SZM2 linkage radius block

This radius block is supplied as an RC-scale spare for the EMBLA SZM2 helicopter series. It functions as the interface point that sets and limits the motion envelope of rotor linkages in collective and tail assemblies.

Fitment and checks: confirm correct alignment and unobstructed movement on the intended linkage path prior to final assembly, use proper fasteners and thread locking for model screw threads, and ensure there is no binding across the travel range. The component is intended for routine servicing and part replacement on scale helicopters.

Tuning role: fitting a new radius block when linkage parts are worn reinstates correct mechanical geometry and helps maintain trim precision during setup and flight testing. Inspect the linked parts and bearings for wear when replacing this item.
