I was flying my inspire in ideal conditions. warm clear sunny day flying in a open field direct line of sight about 250 yards away at around 120 ft when I lost all control and power. The drone fell right out of the sky and was severely damaged. This was probably my 5th flight with it. I am incredibly thankful I was over a field and not a populated area. DJI also kept the memory card with the video of the crash on it. I stupidly didn't download it off before sending it out. I sent it in to DJI and they gave me a replacement unit no hassle. But I am still left with a lot of questions. Why did this happen? How can I precent this from happening? How can I trust DJI not to drop my drone from the sky again?
