The yaw rate in a turn is also affected by the bank angle - to the extent that in a 90 degree banked turn, there is 0 yaw rate - all of the heading change is due to pitch rate, so your statement that ''if there is no yaw there is no turn'' is technically incorrect.
I did wonder if someone would come up with that fallacy! In a level, balanced turn a bank of 90 degrees is physically impossible. Bank in a level balanced turn must always be less than 90 degrees so a yaw vector must always be present, no matter how small!

I agree with Harry C.
I have used a rudder gyro on my warbirds for twenty years when you use to hear the tiny gyro spinning away inside the black box.
When I make a LEVEL turn with the gyro still on everything is normal.
When I happen to let the nose drop in a turn with the gyro on I can see the gyro giving me TOP RUDDER and the turn feels like st. This is why I turn it off after takeoff and back on for the landing. On some birds I seem to be able to have a low rate of gain on all the time...some others I can't.
And I never use heading hold.
