Introducing Gemfan's new glass fiber propellers. These new props are much stiffer than traditional nylon or ABS material props.
GemFan produces some of the finest propellers for Multi-Rotor use, and they are available in a variety of colors and materials.
The 6x4.5 props have a 5mm hole drilled in the front side of the hub. Included with the prop is a set of OD adapter rings that step down the center hole of the prop to allow it fit on 2mm, 3mm, or 4mm motor shafts. If you have a larger threaded shaft on your prop adapter, the center hole can be reamed out to a larger size as needed.
