What if the thrust line is not parallell to the a/c hartline? If the engines have toe-in or -out, then there is an additional vector. Then the position of c/g will have effect (slightly).

The story goes, that the DC-9 wing was a barely modified DC-8 wing. The DC-8 had excellent stall properties, so the DC-9 was expected to show the same good qualities, but it did not. Eventually, it...
