I'd venture that the current helicopter aerodynamics books by no means contain or perpetuate "myths".
For my money (and I'd extend this to fixed wing to a fair extent as well) the problem is that there are books for engineers, books for pilots, and very little that brings them together. Without doubt Nick is the sort of chap who can plug that gap. (Shawn has to a fair extent also, but is probably just a little busy right now!)
