Well after a great weekend flying vision with new drone expert gimbal it found a watery grave in Newport Harbor in Newport RI. This last picture it took before crashing . I noticed similar problems other experienced everything was going fine and some kind of interference caused the phantom to just nose dive for no reason. I tried to steer clear of cell phone towers, power lines etc. Let this just be a warning to others flying around low for at least 2 minutes make sure no interference in the area. Unfortunately this it is for me just can't have a couple of thousand fall out of the sky for no reason again. I'll be selling my go pro case, chargers and batteries (4) well below cost in classified section if any one is interested. Hope others have better experiences.
