Scott, can't agree with you
on this one. The wings DO carry more than the weight of the airplane. They
also carry the aerodynamic "weight" of the tail down force. Moving the CG
forward increases the total lift required from the wing. The greater
lift is provided by increasing the AOA, therefore putting you just a little
closer to a stall, ergo, moving the CG forward also increases the stall speed,
even though the aircraft total weight remains the same.
