I know all about dissymmetry of lift. Quote away. However, it doesn't change the fact that the moment produced by sitting on one side or the other is miniscule compared to that produced by the cyclic control.
And for the record, the stabilizer (or "little wing") on the back of the B206 and most other helos is there to reduce drag by keeping the fuselage more or less aligned with the airstream in cruise. If you look closely, they're heavily cambered and it's easy to tell that they're both providing a downward force to counter the forward pitching moment imparted by the rotor disc in forward flight. They're small because they're pretty far from the longitudinal CG. If they had to provide a lateral force, they'd have to be much bigger.
Well, it's pretty obvious that no one is changing Angels' mind so that's about all I have to say on this subject. I do have one parting question, though: So if you're carrying a passenger, do you make them sit behind you, or are they allowed to sit up front?
