RC Helicopter Linkage Parallel Pin 2 x 11.6 - Hirobo HI2509012  [HI2509012]

Compact parallel pin for linkage repair

This RC parallel pin is catalogued as part 2509-012 and referenced by model HI2509012, supplied as a spare for common helicopter repairs. The specification "2 x 11.6" identifies the pin dimensions you must match to your model's parts list.

It serves as a locating pin in small linkage assemblies and pivot points on rotor systems, intended to replace lost or worn pins of the identical "2 x 11.6" size to keep control geometry correct.

Installation is simple: line up the linkage or bracket hole with the pin, insert the pin fully, and fasten it using the original retainer or clip supplied by the airframe. After installation check for lateral movement and confirm rotor tracking is unchanged.

For setup and routine maintenance the pin is a minor but necessary item: accurate pin selection supports proper linkage geometry and predictable cyclic and tail behavior. Inspect mating holes for debris or wear before fitting replacement pins.
