Hirobo HI2521082 Collar 5 x 6.5 x 14 — Collar for helicopter general parts  [HI2521082]

Helicopter collar overview

This is the Hirobo HI2521082 collar listed as "COLLAR 5 X 6.5 X 14" in the Hirobo helicopter parts range. It is an RC-scale accessory intended for use within helicopter general parts assemblies, serving as a locating and retention element on rotating shafts and internal linkages. The nominal marking "5 x 6.5 x 14" is presented on the product label and should be used to check fitment against your model.

The part functions as a straightforward mechanical spacer and retention collar, helping to hold bearings, gears, or other components in axial position during operation. Fitment is determined by matching the label dimensions to the shaft or bore on your Hirobo helicopter or compatible general parts assemblies. Installation typically requires access to the shaft location and basic hand tools; check the model's assembly notes for torque and orientation requirements where applicable.

For tuning and maintenance, this collar is useful when adjusting component endplay or when replacing worn spacers during routine servicing. Because it is a generic collar part within Hirobo's parts hierarchy, confirm the dimension set before ordering to ensure proper integration with your existing rotorhead or gearbox elements.
