imabell, if you're who I am referring to, you certainly look a lot younger and energetic than 63 - please take that as a great compliment !
Robbo Jock, agreed that we should be talking about the disc, not the fuselage. I think it depends on the rotorhead setup - in a rigid rotorhead, I expect the fuselage to bear a pretty much fixed relationship with the rotor disc, while in a teetering head the disc is entitled to have an attitude/mind of its own.
