I came across Earthstar Aircraft's Gull series of light planes and was highly impressed. The thing that puzzles me the most is how they are able to get such a slow stall speed out of a small wing and a reasonably high weight. I've contacted the designer and he insists that stall speeds were measured at gross weight. In every review of this plane that I have read, the stall speed given was really close to the specs given by the company. I know they use a 40% plain flap. Any thoughts on how they get so much out of that wing?
The specs are given here:

I get an overall Clmax of almost 3.1 when running the numbers. How on earth does it get this value? Thanks.
