Dan,

When I have my AW Edge setup for sequence flying (forward CG)I tend to notice the same thing. Jason Danhakl gave me a rule that I have always used when setting up CG for 3D. Roll the plane inverted...should have to add very small amount of down elevator to stay horizontal. The AW seems to perform the harrier very well at that neutral CG location.

Not as pretty, but bursts of throttle will allow you to push the tail down, and achieve a very high angle of attack at almost any CG.
