Sceadu SD Collective Pitch Bolt HI0412132 for RC Helicopter Rotor Linkage by Hirobo  [HI0412132]

Secure collective pitch bolt for Sceadu SD

This RC-scale component is the collective pitch bolt Hirobo HI0412132, intended for use on Sceadu SD series helicopters. The part is described as the securing element within the collective pitch linkage rather than a generic fastener.

The bolt provides a pivot or attachment point in the collective pitch system, holding linkage assemblies that control blade pitch. When replacing this bolt, confirm alignment of linkages and verify full, free movement of the collective mechanism before flight to prevent binding or asymmetric pitch response.

Installation notes: hand-thread first to ensure correct engagement and alignment, then tighten in small increments until the linkage is held without play while preserving smooth travel. Do not over-tighten and inspect adjacent link rods and ball links for wear while the system is open. This item is an RC accessory and not intended for full-scale aircraft use.
