Josey,
Try using less rudder. You still need some, but that flopping thing, and having the AOA way too low when exiting a turn is from overcontrolling the rudder. Many planes are easier to harrier inverted than they are upright, as long as you know the orientations. So relax a bit, try using the ailerons and elevator to turn in inverted harrier compimented with the rudder to bring the nose around.
