DJ77 Another point where I doubt Owain’s conclusions is the estimation that, at high AoA, the mean aerodynamic center will move longitudinally to the wing center of area, hence behind the CG.
in which height lays the CG over the wing (over the aerodynamic center) ? for the stability intresting is the horizontal distance, but with an pitch >15 deg the CG begins also to move back if it is high over the wing
