40mm Turbo Spinner for 4mm Shaft

Turbo spinners have air intakes for motor cooling and include middleparts and prop shaft adapters

These spinners have a hole in the front that lets air enter through the nose of the rc plane - a great way to cool the electric motor instead of using a fuselage air scoop. Included: turned aluminum spinner, middlepart yoke, screws for prop blades, and collet type motor shaft adapter. The width between the arms of the prop yoke is 8mm. AeroNaut folding propeller blades have 8mm wide hubs. For DKT3623, use Graupner Scimitar or CAM folding prop blades. For all others, use AeroNaut CAM Carbon or Classic Carbon folding prop blades.
