Hirobo HI2509002 needle pin 2 x 8.8 for helicopter linkage  [HI2509002]

Needle pin for helicopter linkages

This Hirobo needle pin HI2509002 is an RC-scale replacement pin intended for general helicopter parts where a compact, straight pin is required to secure linkage joints and control rods. The product name specifies the usable dimension, allowing hobbyists to confirm fit against existing linkage hardware.

Installation is straightforward: align the control rod or ball-link eye with the mounting hole, insert the needle pin through the mating parts, and retain with the original clip or retainer on your model. The pin's primary role is to provide a simple, repeatable pivot point that keeps linkages aligned during setup and flight tuning.

In tuning and maintenance workflows the needle pin is a low-complexity part that supports precise geometry adjustments—swap to a fresh pin when wear at pivot points begins to introduce slop, and verify secure retention after any control-system changes. As with all RC-scale hardware, check fitment against your helicopter's linkage locations before long-term use.
