Aero-Naut Precision Spinners - these spinners use the same component principles as the CoolNose product - just without the provision of the extra air intake and are only available in black.

Choose spinner diameter together with collet size to exactly fit the shaft of the motor being used.

Always use a Centrepiece at least 2mm larger than spinner diameter so the blades fold correctly.  A smaller Centrepiece is incorrect and will not function properly.

The variants list above shows diameter followed by collet size.
