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

Precision linkage radius block for SSZ-IV

The HI0414465 radius block is offered as a replacement item for Turbulence D3 SSZ-IV helicopters. It positions the control linkages, influences tail response and cyclic sensitivity, and functions as a small mechanical replacement used during servicing or adjustment.

This item is part of the helicopter control linkage assembly rather than an electrical or drive module. Before finalising installation, confirm SSZ-IV reference numbers and trial-fit the block at the tail and control horn to ensure correct alignment.

Fit this radius block when restoring original geometry or replacing degraded parts that change tail authority and cyclic feel. Carry out bench checks and controlled flight testing after replacement.
