By Yaw I assume you just wish to rotate the Mavic around its camera axis while ascending or descending to get a spinning effect which you have figured out . You can also Fly in POI mode and select the Point Of Interest you wish the camera to remain focused on while it circles around it . After setting an initial radius , height and speed to start you can also manually adjust the radius , height and speed while it is circling the POI to get a spinning , funnel effect .
