2 x 28 Parallel Pin for Hirobo Models - Hirobo HI2509019  [HI2509019]

Precision locating pin for link assemblies

Designed as a scale RC replacement, this pin suits routine maintenance and small-part swaps. The HI2509019 denotes a 2 x 28 parallel pin intended for Hirobo helicopter parts, used as a simple retention piece in control linkages and small joints.

In service it provides a compact locating and retaining function: when inserted through mating parts it limits axial movement and helps keep linkage alignment. As a basic mechanical connector it trims end-play and establishes consistent pivot points that affect servo response and trim behaviour.

Installation notes and practical tips:

• Ensure holes are aligned before installing to prevent the pin bending or damaging mating components.
• Orient the pin correctly and press it in so it sits flush with surrounding parts to maintain correct linkage geometry.
• Check for signs of wear or corrosion at each service interval and replace the pin if any deformation is visible.
