A "normal" turn is accomplished by splitting the lift vector, NOT by 
holding in yaw. Yaw should only be present in the turn dynamic during 
the entry into the turn and exit from the turn. Once stabilized in the 
turn, there should be no yaw present. There could be however if the turn 
was a slipping turn or a skidding turn.
