After two months hassle with the supplier in my country, I finally got my faulty Vision 2 Plus V2 replaced to a V3. I received it yesterday and was AMAZED over how it is to fly with functional GPS! After receiving it, I upgraded to latest firmware (3.12), updated the main board, did IMU calibration on a level surface and a compass calibration pre flight. Doing 360 video pans with GPS lock, using IOC-functions and having them actually work, getting 10-12 satellites locked was just a dream come true compared to my GPS-faulty V2. I had three full 20min flights and everything was working perfectly. I flew it 200m out and 200m up, everything worked flawlessly! But then, all of a sudden, I was about 50m out on the exact same place I flew two times before, taking a photo of the cabin next door. The altitude wasn't more than 5-10m. I was hovering it in place to take a photo, and it all of a sudden flips fully up side down and smashes into the ground. It was just absurd, I had three friends next to me watching and they have no idea what happened. There was no input on the controller, and the battery was about 40% when the crash occurred. GPS mode, no IOC. 12 sats locked. Controller was 4/5 charge. Wifi repeater at 90%. Iphone at 70%. Far out in the middle of nowhere in the Norwegian mountains, there is barely cell signal here. It just went for a full barrel roll, and bam, game over. Found it laying in the bushes covered in snow, the battery popped out as I lifted it up and after drying it up it seems like the gimbal now is screwed. As I turn it on, the lights flash, and the Phantom beeps continuously without any LED-signals. The exact same sound as after you update it. Does anyone have any idea what this means? From what I know there's no way to find out which part is actually faulty than removing everything and connection the different additions one by one. My gimbal is working fine initially, but after moving it around it sits at a crooked angle and seems very out of shape. Connecting it to the computer does nothing, the Phantom software does not seem to make any contact with the Phantom. I have had about 25-30 flights with my previous V2, have also had heaps of training-flights with my Hubsan X4 and never had anything like this happen. Have anyone else experienced anything like this? Other pilots out there with any clue to what could have caused this?
