. I think the speed with 2610 and B has alot to do with people not sticking with combat more than a few mid-airs. These proposals can be modified. I hope Master Airscrew comes out with a 10x3 prop. We could set a rpm limit just like SSC.
Make it low enough that header pipes and Ky mouse can won't be needed to be competitive.
