Hi guys. Pardon the silly question. I read flying magazines(fullscale) and was reading a while back about a guy who built an exp. float plane. He stuck a zillion vortex tabs on the wing near the leading edge and was able to take the stall from 43 knots or so to 28 knots. Can somebody explain to me how they work? I see them on a lot of Jets I fly on now too. Thanks guys. Keith
