I like some of the characteristics of this airfoil but not the sharp stall behavior at the usual Reynolds numbers. The lift coefficient is excellent for such a low pitching moment airfoil. Does anyone have lift-curve, drag, pitching moment, etc, data for this airfoil at low Reynolds numbers? I am interested in R numbers corresponding to 30 to 100 mph with a wing chord of 4 ft. or 5 ft. Is the stall behavior appreciably better at low R numbers? Does Harry Riblett, or any reputable source, have a development of this airfoil series with high lift, very low pitching moment and with a gentle stall?
