Hirobo HI2530005 Pivot Bolt E Replacement Pins for Rotor Linkages, 2 pcs  [HI2530005]

Replacement Pivot Bolt E for Hirobo Helicopters

This pivot bolt E is a compact replacement pin designed for rotor linkage and control arm pivot points on Hirobo helicopters. Supplied as a pair of 2 pcs, the part replaces worn or damaged pivot locations where a stiff, low-profile pin is required to restore proper hinge motion.

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

Installation is simple 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.
