Tonight I unfortunately had my first fly-away. I was flying behind my house on a field, taking pictures of the sunset and the mountains. All went well for the 1st 5 minutes, and then suddenly I noticed that the drone would not stay in place anymore when I released the commands. I immediately tried to bring the Inspire down, but before I knew it, it starting flying south at full speed. I tried to regain control by switching to ATTI mode, but it would not respond. After approx. 70m, the Inspire changed direction and well full speed north. Since I live on a hill, I heard a big bang, and once I had climbed the hill, I found the drone crashed into a concrete wall next to a house about 100m away from my location. Drone is a pretty much a total loss. At this point, I must say that I am mostly glad that nothing happened. Losing control of a 3kg drone that lives a life on its own is very scary. Particularly so, when I have had many flights before without issues, slowly gaining confidence after all the horror stories. I had been practicing ATTI mode as suggested in the forum as a potential recovery during a fly-away. Before take off, I checked all the values and they seemed ok. During the initial 5 minutes, where I started with some test movements everything was fine. Needless to say that I find it amazing that after releasing the drone 8 months ago, such serious fly-away issues are still around. It raises a serious question how secure the Inspire 1 really is and whether the drone is a hazard in non fully open space. Curious to see how DJI will respond but I am not very hopeful, reading some of the other reports.
