I see these kinds of things on Amazon, and it really worries me. Why do some people seem to have trouble-free phantoms, while others seem to have catastrophic failures? 1.0 out of 5 stars Purchase at your own risk., September 18, 2014 By onealmr - See all my reviews This review is from: DJI Phantom 2 Vision+ Quadcopter with FPV HD Video Camera and 3-Axis Gimbal (Electronics) I have had 2 DJI Phantom Vision 2 +. The first one dropped from the sky at about 60 ft but the book and internet does say to avoid flying around power lines and I was over power lines albeit well above them. It messed up my camera gimble and had a damaged camera ($650). Instead of repairing the item, I decided to use it as 'parts' and bought another vision 2 +. Keep in mind each of these are costing me $1200 a piece. After my 10-12 flight, many of them over a 60+ acres cow field till I felt I was at an intermediate level of flying. Flying back to me. Direct line of sight. 8 Satellites. 50 feet in the air and 30 meters from me cruising at a slow speed (remember, the goal is to learn how to fly "like a pro", not be a speed demon. You must crawl to walk to run, to etc). All the sudden, with no reasonable excuse, the Phantom 2 Vision + went crashing to the ground. It again damaged the 3D gimble and camera. There must be a fix for this as I'm out an already $2400. Both of them, prior to first flight, had been firmware upgraded via the USB cable and their programs straight from DJI.
