So today I installed the new iOS app. I did not fly since installing iOS 9. On my first battery I flew with my new iPhone 6S plus. The battery was at 57% because they had started their auto discharge from sitting a couple of weeks. I figured I would run them down before doing a full charge and check out the app. The first battery was fine. I then switched to my iPad mini 2. This battery was also at 57%. I took off went up to around 375 feet all the while I was going forward and turning to the right. At about 30 seconds in I got a critical low battery warning and the craft started going crazy. The gimbal started leaning to one side and went into an arc to the left. I tried to bring it back, it was only 500 feet away. It was flying sideways even though I was not imputing that into the controller. I got disoriented and then it lost signal and went down. The weird thing is on Facebook I have now seen this same problem twice. Just wonder if anyone else seen this.
