Hi Crab, I try not to post on these forums, especially to give advise but there seems to be some misinformation. My concern was the unnerving posts about people loading the disc with collective, which is undoubtably the wrong thing to do. Increasing the torque that is flipping you will just kill you quicker.
I think you are right in that in a completely unloaded disk i.e. zero G, then you have no control power. Any right, left or aft cyclic wont do anything at that point but I think if you get to that position the horse has pretty much bolted and you are just along for the ride.
