well,I did it mathematically...I drew an angle from my chord max alt,along the chord, at wing fuselage base at 2*.Call it the center of my wing spar. That made my dihedral,then rotated the whole airfoil 2 degrees to give me my angle of attack.I put a copy of that airfoil at the distal end of my spar(which I rotated about my max chord locus -2 degrees at the trailing edge).I then drew a line from the trailing edge at the fuse,to the trailing edge at the far end of my wing.I spaced my profile along those 2 lines at 3 inch intervals along the wing(48 "),using the dihedral line,and that trailing edge line,to align my profiles.Each profile is rotated -2 degrees divided by 16(the number of ribs)=.125 degrees.
