3) Rudder to keep aircraft in balance/prevent further yaw
NB: 3) Is nice but, in my opinion, not vital as long as 1) and then 2) are carried out.
Wouldn't dispute that.
My point, perhaps missed, was that worrying about maintaining constant heading is silly, and the only thing you should be doing with the rudder is keeping the ball in the middle.
(At least nobody has mentioned "picking up the wing with rudder"
)
