RE: convert flat bottom wing to semi elliptical
Have I been misusing the term camber? My airfoil doesn't have a reflexed camber line like the first picture below, but it does have "that little undercamber cusp on the lower rear" that Bruce mentioned that is similar to the undercamber cusp on the upper rear of the first picture below. FWIW I've added a picture of the mean camber line of the original flat-bottomed Eagle 2's airfoil (red line and airfoil shape) and the mean camber line (blue) of my modified airfoil by adding the blue bit on the bottom of the red airfoil.
edit: Maybe I should have said that my camber line has a tighter radius aft of the spar than the original Eagle 2 airfoil instead of saying that it has more camber aft of the spar.
