That does sound like a very simple and effective method of yaw dampening. I have seen full scale setups similar to what you described that would only deflect the inboard fin as a rudder and it worked very well. I think ululi 1970 was more interested in a active control system as an alternative to a fin rudder type of setup.

Here's how you do an all flying wing the right way!

123" wingspan, twin 90mm edf's, 33lbs. NO vertical stabilizers. "Drag rudders" used for marginal yaw control.
