Collective link bolt built for Sceadu SD

This RC-scale item is the Hirobo HI0412132 collective pitch bolt, made for Sceadu SD series helicopters. The description highlights its role as the fixed link in the collective pitch assembly rather than a general-purpose screw.

The bolt acts as the pivot or join point for collective linkages that adjust blade pitch. When fitting a replacement, ensure linkage geometry is correct and that the collective travels freely across its entire range to avoid uneven blade pitch or binding.

Installation notes: begin by threading the bolt by hand to confirm proper mating, then incrementally tighten while monitoring linkage motion. Avoid overtightening and take the opportunity to inspect surrounding components like ball links and rods for wear. This component is supplied for RC use only and not for manned aircraft.

What wear indicators should I look for on HI0412132?

Look for thread deformation, rounded or flattened bearing surfaces, and any visible bending. Any of these signs warrant replacement to maintain smooth collective action.

Can this bolt corrode and how do I protect it?

Corrosion risk depends on material and exposure. Keep linkages dry, apply light corrosion inhibitors where appropriate, and check joints after flying in wet or salty conditions.

Is regular replacement recommended?

Replace based on condition rather than a fixed schedule: inspect during routine service intervals and replace if wear or damage is detected, or after impacts that may affect alignment.
