I think I understand a little better what your struggling with. Ignore my first post. It's not wrong but Keith's is much better for the purpose.

I assume you are trying to fly straight and level at a very high angle of attack but not hovering. You can do this with a fully stalled wing, partially stalled, or flying wing. Remember a stalled wing still produces lift but has a real bad lift to drag ratio and controllability problems.

The the thing your struggling with is not whether the wing is stalled but where the CG is with respect to the center of lift. In a stable plane the cg is forward of the center of lift and as the airspeed increases it causes a pitch down moment. If the cg is aft of the center of lift increased airspeed cause a pitch up moment or with a reduction of speed a loose of lift on the horizontal stab and a resultant pitch up, unstable. This is probable what you are seeing. when you increase or decrease speed you see the nose come up, the speed drop, the airplane start to fall and you interpret this as a stall. You probably were already flying in a stalled condition but that's not really important. What's important is how to use the elevator with an aft cg. I have two planes that are real bears to land when the fuel tanks are empty because of this. Very slight AOA changes cause large moment changes in pitch that take quick reactions on the elevator to control in slow speed flight.

I hope this helps but these forums are tough for this kind subjects.
