Kent, No, I don't know enough about the aerodynamics of Caps to say that, certainly I have found all of my aerobatic airplanes make beautiful landings (pilot get some credit too, brag). Also all of my airplanes have the horizontal and wing pretty well aligned so I wouldn't see the effect.

According to legend and while designing the F-4 and while analyzing the wind tunnel data the engineers supposedly found a severe nose up hook in the pitching moment curve at high angles of attack. They decided it was an artifact due to wind tunnel testing.

Later on in flight test it was found to be real and would insure a departure at certain flight conditions.

If we had some wind tunnel data would we see the same with the Cap? I wouldn't expect it to be big (it wouldn't have to be much) but would expect it to be a function of where the horizontal tail is vertically located relative to the wing. I'll stick on a quick, bad, exaggerated, sketch of what might be happening.

Keep in mind this is just a theory, without wind tunnel data it is a SWAG, Scientific-Wild-A__-Guess. But other than the horizontal tail location the planform, areas, etc. of the Cap are fairly normal.

If I remember correctly the T tail setup used on a lot of commercial airplanes for drag reduction, etc., also has a pitchup at high angle of attack.
