From what I recall, yes, the onset of Dissymmetry of Lift and ETL will cause the nose to want to rise, but I don't recall it being all that much. I mean, my subconscious just pushes through it anymore, so I haven't experienced it in years.
Yes, as a commercial pilot, I have definitely learned to push through without any thought. As a new-ish CFI, I see students wrangling the helicopter throughout the takeoff, and I wanted to really understand the aerodynamics so that I can explain it thoroughly. I’m sure the “just push forward” explanation that I was given would probably suffice, but I also enjoy this pursuit of better understanding.
