80MM Red Four-Blade Propeller 1.95MM Hole

The 80MM Red Four-Blade Propeller is an 80 mm diameter, four-blade red propeller with a 1.95 mm centre hole. The hole is slightly smaller than a 2 mm motor shaft, so the propeller press-fits firmly onto small DC motors such as the common 130 size, without glue or an adapter. It is popular for DIY fans, air boats, hovercraft and school science models.
