Turbulence D3 SSZ-IV Radius Block HI0414465 - Hirobo  [HI0414465]

Direct replacement radius block for SSZ-IV linkage

This radius block is a direct-replacement scale accessory listed as HI0414465 for use with the Turbulence D3 SSZ-IV designation. The component locates the control linkage, affects tail authority and cyclic feel, and serves as a routine replacement part used during maintenance or setup changes.

Intended for model-level RC helicopter linkage work, the part is a mechanical control item rather than an electronic or drive unit. Installers should confirm SSZ-IV part codes and check fit at the control horn and tail assembly before completing the installation.

Use this radius block to restore correct linkage geometry or replace worn pieces that reduce tail authority and alter cyclic feel. Always perform a bench fit and a cautious hover test after fitting.
