that is what I am getting at.The sum total at the rear of the tip outer chord.is 4 degrees dihedral,whereas the chord dihedral(usually at the max Height of the chord),of the basal airfoil,is 2 degrees.The chordal dihedral ,is drawn as a line inclined at 2 degrees,and the washout is drawn as a line from the posterior tip at -2 degrees,resulting in a horizontal trailing edge,and a climbing max thickness line following the 2 degrees dihedral
