Remember, though, that "flapping to equality" is negated as soon as you put some cyclic in to stop the blade flapping away from the relative wind and to maintain forward speed.
In forward flight, when the disc is tilted forward, the advancing blade is actually flapping down and the retreating blade is flapping up - or else the disc would not be tilted forwards , would it? The cyclic feathering overcomes the desire to flap to equality. Go back to neutral cyclic, and you are back in the dynamically unstable flapping to equality.
