Posted a problem I had on Saturday with losing signal. Was worried that I might have a faulty Phantom. Decided to work with it today for a bit. Did a few shorter flights this morning. All went well. Watched everything, loaded all info in Healthy Drones, etc. Decided to take it out at about 5:30, this was the 4th flight today. All was going well, got it out where I was going and turned around and headed back. It was probably 300 ft away when I saw "Battery Error" flashing in red on top of the screen. I never saw this before and was trying to get home as quickly as I could. It was at an altitude of 325' and literally across the street from my house when it went suddenly quiet. Not good. All I could do was watch as it plummeted to the ground about 50' away in the yard across the street. I tried yanking the controls down quickly hoping to restart. No go. Can't explain that feeling I got watching it fall. Not sure what would cause this. It basically just shut off in mid-flight. The logs don't even show any problems. They just end at the point of power loss. Can't even view the video, as it must have been damaged in the fall, because it won't play at all. Very troubling, in that I got very lucky it landed in a grassy yard and not on top of a person, car etc. I bought through Amazon and they are sending me a replacement, so I am lucky there also. Has anyone else had this happen using the current firmware. I was on 1.6. Also, in case it's important, it was 75 degrees outside. No cold weather.
