Yea - I have: The picture of wings flying themselves to a new plane of rotation is spot-on. And it is now the concensus here, which is an arguement I have been pressing for over (a long time) years, when it was not widely recognised. It used to be (and still is in exam-land) taught as 'gyroscopic precession' in most text books, (inc CFS, crab), because it was a covenient 'packaging' of the topic. (just like it is convenient to talk about Flapping to Equality being the soloution to DoLift - whereas it isn't really).
I've never seen it taught thus. My initial rotary course as a student pilot was thirty five years ago, my CFS course thirty years ago and it was never described as gyroscopic precession during that time or since, except when someone here comes up with a "new" theory. Seems to me that when you begin to lose an argument you simply precess your viewpoint to act in a different direction.
