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

Replacement collective bolt for Sceadu SD

This RC-scale component is the collective pitch bolt model HI0412132 from Hirobo, designed for use on Sceadu SD series helicopters. It is presented as the securing component within the collective pitch linkage rather than a universal fastener.

The bolt functions as the pivot point in the collective system, connecting linkage elements that alter blade pitch. When fitting a replacement, check that the linkage alignment and full travel are correct so that the collective moves freely and symmetrically.

Installation notes: begin hand-threading to confirm correct threading and alignment, then tighten in stages until the linkage is retained without play but still moves smoothly. Avoid over-tightening and inspect adjacent parts for wear. This article is intended for RC use only and not for full-scale aircraft.
