Hirobo HI2530005 Pivot Bolt E Set - 2 Pieces for RC Rotor Linkages  [HI2530005]

Pivot Bolt E - Service Replacement

The HI2530005 pivot bolt E is a small-scale replacement pin intended to service rotor linkage and control arm pivot points on Hirobo helicopters. Supplied as two pieces, the item is suitable as a direct swap for worn or damaged pivots where a compact, rigid pin is required to restore correct hinge action.

Use this component when a pivot point shows play or wear that alters blade or tail linkage geometry. The part helps maintain correct alignment between control linkages and rotor assemblies, supporting reliable control inputs and easier trimming during setup. It is intended for maintenance and discrete repairs rather than performance upgrades.

Fitting is straightforward for a competent technician: detach the affected linkage, replace the old pivot bolt with the new pin, check for secure yet free movement, and reassemble. After refit, verify rotor and control travel to ensure there is no binding and that trim settings hold.
