Sez Nick:
Yes, very interesting discussion of fixed-wing dihedral effects.
An airplane with zero dihedral would exhibit very little yaw/roll coupling. Also, airplanes do not have a hinge where the wings and fuselage meet, as the 212 does.
So how does a discussion of dihedral relate to helicopters? Or I guess my question is "how much dihedral does a helicopter rotor have?"
