Hirobo HI0304118 EMBLA SZM2 Linkage Radius Block  [HI0304118]

Technical summary of the EMBLA SZM2 radius block

This radius block is manufactured as an RC-scale spare for the EMBLA SZM2 helicopter range. It operates as a linkage interface component that locates and manages the travel path of rotor linkages within collective and tail systems.

Fitment and checks: ensure the block is aligned and that linkages move freely through their range before finalising assembly, select proper fasteners and apply suitable threadlocker for model screws, and verify there is no binding across full travel. The item is meant for scheduled maintenance and part renewal on model helicopters.

Tuning role: replacing degraded linkage elements with this radius block returns accurate mechanical geometry and preserves trim reliability during setup and test flights. Check all mating bearings and link ends for wear when swapping parts.
