I had something strange happen today. After not flying for a week I took my phantom out for a simple flight that I never ended up taking. When I took off, it started leaning slightly to one side, like it was maybe fighting wind. There was a 9mph wind to be clearn. Then it starting drifting a bit. First to the right, then towards me, about 4 feet in either direction. I was about 5 feet off the ground, and decided to land it. Then I took off to 5 feet again and got the same result. I was somewhat near some power lines...about 150 feet away. Any ideas? I didn't take it for a flight because I figured I may need to calibrate it or something. Maybe I'm just to jumpy, but I've always felt the p3 to be pretty rock solid in one place. Thanks for any input!
