Can someone check my work for me? This is scary if I am right.

If I can turn a 16x4 wide at only 8000 rpm, then my max speed in level flight is only 30 mph!

(4 inches * 8000 rpm * 60 minutes)/(12 inches * 5280 ft)=30 mph of wind

For a Cap 231, that is kind of slow. I am not sure what stall speed it, but it is not far below 30 mph. Maybe my calculation is worthless.
