The Quanum series of carbon fiber propellers have been specially designed for multi-rotors and are manufactured to very exacting standards. They are extremely light and strong and you can expect an increase in performance due to their ultra thin and stiff carbon construction.
As supplied these propellers are ready to fit a 6mm shaft but this can be reamered to suit shafts up to 10mm, adapters for a 5mm shaft are also included.

I must say, these props are pretty disappointing. I purchased 4 sets and 3 of the props have noticeable ridges on the underside of the prop, in what appears to be a molding issue when they were fabricated. The outer hub diameter is only 13mm which does not provide a lot of surface area for the self-tightening prop hardware to grab onto. Additionally, because the hub diameter is so small, there is not a lot of strength to support the blade, resulting in a lot of vertical flex in the prop near the hub. After a minor tip over on one landing, one blade snapped off right at the hub. I dont recommend these props.
