This morning, I was flying my Karma about 1,500 feet out over a river and after about 10 minutes of flying over a small island in the river, I turned the drone back toward me. As it was flying back to me, the controller went black and said ‘lost camera connection’. Then it said, ‘returning to takeoff location’. Then it did a countdown and said it lost Karma connection. I lost sight of the drone when I was looking at the screen and am pretty sure it’s now at the bottom of the river. My question is, what is the drone’s behavior if it loses camera connection? Does it really attempt to return to the takeoff point, or is it a lost cause at that point? I am not sure what caused it to lose camera connection in flight and don’t know if there was anything I could have done to keep it from going down. Anyone had any experience with anything similar?
