Subject line pretty much says it all. All the same equipment from flights 1 through 34. The only change was the iOS Pilot App version on the 2nd flight using 1.1.2. The P3 was only 20ft up and maybe 30ft out when it happened. It happened only minutes after I lifted off and I waited maybe 1 minute for it to come back but it never did so I landed and power cycled the P3 and the iOS App. After that I flew without issue for 15 minutes and went out to about ~4,500ft. Note, my first flight on the iOS 1.1.2 version I could not start my props. The Pilot App was giving me a Barometric Sensor Out of Range error when I tried starting the props. Everything in the Pilot App was Green and good to go. In and down with the sticks and the Barametric Sensor error. I cycled the P3 same error. I cycled again and it went away. I haven't seen it since. 1.1.2 appears to be a bit buggy. And my Gimbal is still off. It straightens out like some have reported if I move around but when I stop the horizon slowly goes unlevel. I'll try another cold and level IMU and Gimbal calibration before contacting DJi to send the P3 in.
