While these props didn't go terrible, they didn't have any advantages over a standard 5040 triblade (that I could see), and at this point in time they are not the props for me. I would love to hear your opinions on these props, especially if you have used them in a race environment.
Upon looking more on Facebook, it looks like these DYS version are not exact copies of the Schubkraft version, as the SK are much lighter at 4.5g so I assume they perform much better.
