I have performed a number of experiments using Litchi and an Air 2s trying to obtain a smooth yaw movement as the drone proceeds through its mission. The first was a mission with a reasonable number of waypoints, one POI and the curve size set to 1/2 the distance between waypoints which results in a perfectly smooth circle: ![junk](https://forum.flylitchi.com/uploads/default/original/1X/435fb81b44624600830d2323c3c97681d9c25835.jpeg) As you might have guessed, this did not result an a smooth yaw movement. Next, I tried a similar mission with many waypoints. I got the same result: ![Capture](https://forum.flylitchi.com/uploads/default/original/1X/0e8b04c96bf650a0fe21167ef8af655aa5a0a24c.jpeg) Third, I removing the curved turns, using straight paths between each waypoint. Unfortunately, I experienced the same result. All missions were flown at a slow 5 mph. If there is a way to smooth the yaw movement, I have not yet found it. Again, with my M2Z (on-board waypoints), the yaw movement is perfectly smooth. --- _[View the full topic](https://forum.flylitchi.com/t/adjust-yaw-rotation-speed-and-smothness-in-wp-missions-with-user-controlled-heading/2192)._
