You can go out an experiment with the Vess, or you can take this to the bank. The Edge with a Brison 3.2 will knock your socks off with an MSC 22-8. No, it won't spin a trillion rpm, but that's NOT what determines the ability of the prop to perform. Far too many people have seen mine fly that will never argue the rpm point again. I've run about all of them, and come back to the MSC for the best performance in the group.

The Vess props are also good if you get the right size, 22a I believe. Be careful with the tuning on your engine after you change to one. They put a lot of extra load on an engine and create more heat. Ask RTK about that one[X(]
