People convince themselves of what they want to see!
My post wasn't clear but yes, only referring to using rudder to counter adverse yaw.
Interesting that adverse yaw with anhedral actually accelerates the roll rate.
Lots of other factors too, body shielding of the wing, sweepback on anhedral creating "dihedral" effect. No end to variety with aerodynamics which is why it is always a great topic of debate.
Now how does a Bee fly?
