Hirobo HI0304118 EMBLA SZM2 Radius Block  [HI0304118]

EMBLA SZM2 radius block overview

This radius block is an RC-scale spare designed for the EMBLA SZM2 helicopter family. It functions as a linkage interface component that locates and controls the motion path of rotor linkages in the model's collective or tail assemblies.

Fitment and checks: confirm alignment and free movement in the intended linkage path before final assembly, use correct fasteners and thread locking appropriate for model-grade screws, and verify no binding across full travel. The part is intended for routine maintenance and part replacement on model helicopters.

Tuning role: when replacing worn linkage components, this radius block restores predictable mechanical geometry and helps retain trim precision during setup and flight testing. Inspect mating parts and bearings for wear when changing this piece.
