How does one change Yaw while flying or when one gets to a waypoint. I want to be able to point my hexcopter at the center of a circle while I fly around it. I tried using "Yaw Ang" in the Waypoint within Flight Planner, but nothing happened. My hex just changes it's yaw to the direction of flight to the next waypoint. I then tried using Loiter_Time and setting the "Yaw Per" and that also did nothing. Any ideas how this can be done?
