A little better choice for getting rough estimate of static thrust capabilities of various props and at various RPM's is to look them up in the FlyBrushless.com prop database
. That will give you some real static thrust numbers that were taken by nice guys that also have some credibility here.
Some don't like to use or even look at static thrust numbers, I consider them to be better than knowing nothing at all. And a good startor intermediate step in the process of finding a good prop.
