Precision helicopter collar

This collar is an RC-scale helicopter general part listed under Hirobo HI2521142, designed to act as a small locating and retention element within model assemblies. The stamped dimensions help confirm fit during selection, so check the printed numbers against the shaft or bore on your model before fitting.

Functionally the collar provides axial positioning inside a rotor or linkage subassembly to keep alignment and spacing. For installation, slide the collar into place and fix it using the model's original fastening method, then confirm free rotation and correct axial positioning to prevent binding.

Inspect the part regularly for wear, corrosion, or deformation that might affect performance. Replace the collar if you observe significant wear to avoid damaging mating parts.

What shafts or bores will this fit?

Check the HI2521142 stamped dimensions against your model's shaft or bore to ensure compatibility; the collar is intended as a general Hirobo helicopter part rather than a model-specific OEM item.

Any tips for installing without binding?

Slide the collar to the intended position, secure it with the original fastening method, then rotate the assembly by hand to confirm there is no axial or radial interference before full operation.

Can the collar be reused after removal?

You can reuse the collar if it shows no deformation or excessive wear; inspect tolerances closely and replace the part if fit is compromised to prevent further damage.
