A question about adjusting the CG on the Phoenix. I've been playing with the Integral pattern plane and the adjustment doesn't seem to do a lot, at least when I move it toward the tail. The graphic will indicate the CG somewhere in the region of the stab and its still very flyable.

If I move it all the way forward the plane noses over as soon as it 'drops in' at startup, so the adjustments seem to be taking.
What's going on?
