Hirobo HI2530005 Pivot Bolt E, pivot bolt pin for RC helicopter rotor linkages, 2 pcs  [HI2530005]

Pivot Bolt E for RC Helicopters

This pivot bolt E is a small RC-scale replacement pin intended for rotor linkage and control arm pivot points on Hirobo helicopters. Supplied as a set of 2 pcs, the part serves as a direct swap for worn or damaged pivot locations where a compact, rigid pin is required to restore proper hinge action.

Use this part when a pivot point shows play or wear that affects blade or tail linkage geometry. The component helps maintain alignment between control linkages and rotor assemblies, which supports consistent control inputs and predictable trimming during tuning sessions. As an RC accessory, it is suitable for routine maintenance and discrete repairs rather than structural upgrades.

Installation is straightforward for experienced model technicians: remove the affected linkage, replace the worn pivot bolt with the new pin, verify free but secure movement, and reassemble. After installation, check rotor and control travel to confirm there is no binding and that trim settings remain stable.
