It's probably the middle of the night for you guys - sorry to prolong this even more, but your last comment made me think of something else, lifting.
In forward flight, the helicopter's being skull-dragged forward by the mast head.
Drag on the fuselage can be said to act somewhere lower than that - the bottom of the windscreen, say, at a wild guess. Anyhow, it's lower than the mast.
Those two forces make a couple, which tilts the fuselage forward. Why doesn't it keep going? Because as it tilts, the CofG moves backwards with respect to the lifting point (mast head), and that makes another opposing couple.
When the two are equal, you get an equilibrium, and the whole crazy device flies along steadily with rotor thrust giving a component straight up equal to weight and another doing the pulling forwards equal to the drag, plus the CofG isn't directly under the point where lift is acting, it's behind it.
