specifying the rudder angle

Sorry for the machine translation, I am a Japanese student. I would like to use Ardu plane for my research, but I don’t know how to specify the rudder angle of the plane in the flight plan, I would appreciate it if you could tell me.

I think you must precise what do you mean by “the rudder angle”? The yaw angle? (i.e. the angle between the direction the plane is pointing to and the direction of the flight path)?
