Hirobo HI2509019 Parallel Pin (2 x 28) Compatible with Hirobo Helicopter Parts  [HI2509019]

Compact locating and retention pin

A scale RC replacement designed for helicopter upkeep and small-part swaps. The HI2509019 identifies a 2 x 28 parallel pin made for Hirobo helicopter general parts, acting as a straightforward retaining element in linkages and joints on compact radio-controlled helicopters.

Its role is to provide a compact locating and retaining point: when inserted through matched components it restricts axial movement and helps maintain alignment in control linkages. As a simple connector it reduces unwanted end-play and delivers repeatable pivot behaviour that impacts servo accuracy and trim.

Installation notes and practical tips:

• Confirm hole alignment before driving the pin to avoid bending the pin or deforming mating parts.
• Push the pin in so it seats flush and use the correct orientation to preserve linkage geometry.
• Inspect for wear, bends, or corrosion during servicing; replace if any damage is visible to prevent added play.
