Dear Dave,
Pitch sensitivity increases with aft CG. (i.e. the more forward the
CG the more stable in pitch... the more aft the CG the less stable in
pitch). Also efficiency increases with a more aft CG. The tail pushes
down less, therefore the wing can fly at a smaller angle of attack. AFT
CG is limited by the need for controllability (stability) in pitch.
Before I changed any structure, I'd consider the position of my CG.
Theory Only... but this might help.
