So, I lost my Mavic today... Where flying about 350m (around 1200 feet) from my controller when my DJI Go 4 app (Android) just crashed. I thought, “no worries, this has happened before” so I just restarted the app, but it would not connect. Seconds later the controller displayed “SYS WARNING + CHECK APP”. I had no live feed so I could not make up the directions to take it home. Lowered it down to 50 m (170 feet) to see if the controller responded. It did. Tried RTH but it just said “NO RTH” even though I had 17+ satellites in range. Jumped in my car and drove to the place. Before I reached it, I lost connection to the controller as well. Arrived and the drone was gone. The drone had about 40 % battery when I lost connection. There is no water nearby, only houses and trees. Have been searching now for four days, but starting to lose hope. So, a couple of things I did before takeoff. I re-calibrated the compass because of trouble the day before. Made sure to do it outside on grass with no metal nearby except the controller and mobile attached. . I then proceeded to takeoff and had the drone in the air for about 10 minutes around my house, testing out flight control and making sure that the internal magnet was working as expected. I then landed the drone using RTH. Everything worked. Afther this I perfomed a precise takeoff function so that the Drone could easily return back home, before i proceeded to follow my fligt plan, resulting in the loss of connection and furthermore the Mavic. So I have some thoughts about what could have caused this. Right before the problems started, I switched from Sport mode to GPS mode. The log file show that seconds later the Mavic experienced compass errors, and then I lost connection. The controller never said it entered ATTI mode, but I cannot conclude that this has not happened. My questions to you is: When I lost connection and the drone got compass error, could it have drifted with the wind? The battery as I said was at around 40% so the drone should have stayed in the air for some time. OR could the drone started drifting and then reconnect with the satellites and try to return home? The drone was only 1200 feet from my home, and the Mavic would have had tailwind all the way home so could it be somewhere nearby my home? RTH where set to min. 50 m (170 f) and there is nothing near that height in my area. Also, I am writing a letter to DJI Europe (this happened in Norway) wanting them to take responsibility for this. I believe that the drone had a software error resulting in the drone flying away. What do you guys think about this?
