I was flying the other day and way out there and my screen went blank white. Low and behold, very fast a white cloud was dropping in. I had to fly back totally by "instruments" on the DJI software. Yea, I could have used the "go home" feature, but that was too easy. I just switched to map view and watched my altitude, distance and the indicator on the map where I was. It was enlightening not knowing for sure if I would loose the bird with no pilot view and no line of sight. Has anyone investigated the clip on GPS tracking units? Hate adding weight, and the map GPS view seems fine as long as the battery is good and transmitting signal. Not very precise however.
