Yes. And dont forget the limits. It is my understanding the limit controls the percentage of power dedicated to each function. If anyone can explain exactly what it does I would love to hear it. On my first quad I had these issues, as well as the climb and descend when yawing. High P,I and limit on the yaw function will help cure the issue if it is not a physical problem. Increase all until it starts to climb when yawing and then back them off a little also increase stick scaling on yaw as well. You probably wont get any yaw oscilation from High "P" gain, when the "I" gets too high you may notice the 2 of the motors rev quite high when you resease the rudder stick and the quad will climb a little. If the quad climbs quickly when yawing, the limit may be a little too high. Give that a crack and let us know how you go.
