I'm currently recovering from my loss. It's been a week since I bought my Vision 2 and I've had lots of fun with it until today it just went crazy and crashed. I'm posting here to bring attention to other fellow PV2 owners and to try to understand what went wrong. I have a few theories I'd like to share. So basically I've been playing with it out of the box. Right on the first day I did some nice flying in Germany, where I bought it (I've posted a few videos on the personal videos thread). I've had fuel airplanes and some indoor helis, and this was my first multi rotor toy. I took my time and read thoroughly everything for my first flights. Compass calibration, both switches up, everything connected, and slow green flashing lights before take-off. After around 10 flights, 3-4 battery chargers I got the calibration error and and tried to calibrate it again. It took some time, because many times after trying to calibrate it, it would just give me the red-yellow error. It was a little bit stressing trying to calibrate the compass repeatedly without success. After a while I did get it to calibrate and had no problem at all. I was in Germany visiting my girlfriend for a week and when I returned to Brazil, where I live. I went to fly it in my garden at night. I had the compass problem again and was again having trouble getting it calibrated. I went online and checked whatever there was documented about this issue and found the video of the guy at DJI teaching how to troubleshoot using a magnet. I did the procedure with the magnet and on the next calibration trial It worked. I then flew it for around 10-15 minutes and everything was fine. I charged again the battery and went for some night videos/shots of my city and got beautiful images. I did two short flights and had half the battery left. I Then met a friend and a few hours passed. I tried to fly it again and I the GPS-mode just wouldn't work. I believe it was because it was very overcast and raining a bit. I also couldn't get the camera to work for some reason. Anyhow I went on and flew it out a bit and it was perfect, without GPS. I got home and left the battery charging overnight, as soon as I woke up I went to my garden again for some day flying. It didn't require a compass calibration. I turned on the transmitter, the range extender and the PV2. Both switches up. As soon as I got the slow green blinking lights I flew off fast. I looked at the monitor and then to the phantom and suddenly it started to drift very quicly in one direction. I let go the sticks and it just continued flying fast to the side. I tried regaining control of the thing with no success. It then just flew VERY VERY FAST into my neighbors roof. I freaked out and was very nervous. My neighbors wife started screaming and I was afraid I had kill someone since it just flew like a rocket into her house. I quickly ran into the wall that separates our houses and looked over. And it had hit the roof and rolled 30 feet away. All propellers shattered, on of its arms bent, camera disconnected. I took everything apart to check for all the damaged and I was impressed that It wasn't as destroyed as I thought it would be regarding the great speed that it fell. I think the 3-4 roof tiles broken took a large portion of the impact. The battery took some damage and I the connectors were out of position. I opened it and checked it thoroughly and managed to assemble it back to it's original looks. The shell is broken on top and bent on the bottom. The camera mount also broke. The PV2 wasn't turning on. I then inspected the ESC of the broken arm and it had on the three led lights disconnected from the board, it was rattling inside it's case. After unsoldering the ESC, the PV2 now boots up. So from what I can tell the ESC is damaged and needs to be replaced. I can't tell if the motors are working but the all seem ok. I tested the camera and it also works, the gimbal also works. I remember that the last speed that was on my screen of my phone being 34m/s. All the firmware were updated to the latest. Trying to understand what went wrong, I think there are a few possibilities 1 - System malfunction 2 - Compass calibration problem 3 - GPS loosing lock and PV2 trying to stabilize in position. I have a few questions regarding the GPS lock, and I hope you all could help me understand how it works. It was very overcast and I took off with the minimum satellites (6). What happens if it looses the GPS and is flying in GPS mode? I've read somewhere that maybe the android app has a flight log. Could anyone confirm this? I'm now in need to buy the ESC and I can't find anywhere that have these in stock. I'd also like to know if the shell of the PV2 is the same as the Phantom 1.
