Chapter 8 of the book «See How It Flies», the author J. S. Denker http://av8n.com/how/ This chapter examines, one by one, the various phenomena that affect the yaw motion of the aircraft. There are surprisingly many such phenomena, including vortex propeller - propwash, the inertia of yaw, yaw contrary, P-factor and gyroscopic precession. Plus, the stability and damping set up a vertical tail and the steering wheel. A few translated chapters can be found here http://www.avsim.su/forum/inde​x.php?showtopic=52031
