Lu,
Too bad about the rollover. One occured where I fly--nobody was hurt and the helicopter wasn't too badly damaged. I think it's back in service, but I'm not sure. One must be careful...
In my earlier post, I was saying that you would be able to see the direcion in which the disc tilted (ie, the angle from straight ahead at which the lowest point occurred when the stick was pushed forward). This point, I propose, will be dead ahead when the stick is moved forward. As the stick is moved laterally, there should be a line (running a bit to the left as you propose, or straight ahead as I propose) at which the rotor disc does not rise or fall. I realize that you disagree, but I wanted to confirm we were talking about the same angle. Maybe I'll try to take some pictures next time I go
