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.
