I've managed to get my ac together and in nice trim. It is very smooth to hover, but i have two weird issues with flight.
First one is with forward flight; in stabilize, simple and alt hold modes when i start to accelerate forward, the copter suddenly turns 90-180 degrees to either side around z-axis after short flight.
You can see the issue in video i posted (vid is compilation, about 6 min, this problem is seen in about 4:30, and hey, nice Finnish views too!).
Another issue is with loiter. The loiter radius is about 10-20 meters, gradually increasing, the copter seems to fly rectangular pattern which expands after every turn. Eventually the copter shoots really fast out of control.
Any help is appreciated.
fw is 2.0.42

You do have a magnetometer installed, yes?
I've never had this problem before, but I've heard about it from others. I think it's an uncalibrated compass.
Fly around a bit and then disarm the copter. Disarming will save the compass calibrations.
If you want to verify it's the compass, disable it in the CLI Setup menu. "Compass off"
