I just returned from the park to get in a few practice runs since I haven't flown for a few weeks.
I did a pre-flight exam, took off, and let it hover while I went through the usual checks. WInd was at 10 mph and since I was going no higher than about 20 ft to practice some maneuvers, I was not too concerned. If I was doing a mission, I would have scrubbed it for the day.
So I ran it up to 27ft and hovered while I got lined up to do a manual circle. All of a sudden it shot straight up like a rocket. I had zero stick control and RTH did nothing. I tried all the tricks, switching modes, cancel button, RTH. My mini had only 1 mode, straight up at full power.
By now it was crossing the 1000 ft altitude and I started getting warnings. Motors are at max rpm. Motors are overloaded. Land immediately. At 1500 ft I closed the DJI app and re opened it. It did connect and now my height is 1850 ft. "I am in violation of FAA rules. Land immediately." DUH
1890 ft and all of a sudden I'm reading 1870, 1845, 1810, 1770....... I had the cam pointing straight down and it was right overhead. I never drifted the whole time. Finally got it down to the ground, did a few zig zags and verified I had complete control again, like nothing ever happened.
I came home and did a IMU calibration and called it a day.
Thoughts anyone??
