Dmitry - I believe what you are experiencing is a change in pressure around the craft as it moves through the air. I have observed the barometric pressure reading will drop when you move the craft laterally. The flight controller perceives this drop in pressure as an increase in altitude and will reduce the prop speed to lower the craft to the 'correct' altitude. When the motion stops, the pressure goes back to normal and the craft rises back to its original position.
To test this theory, roll or pitch into the wind. You will see a greater or faster drop than if you were to roll or pitch with the wind. I thought DJI did a better job of fusing their accelerometer data with their barometer data on A2, but apparently not. It's far better than the open source firmware I was using with open source flight controllers, but not as stable as I had hoped. I believe newer generations of DJI controllers (Mavic, Inspire), are much better at resolving the conflict between accelerometer and barometer during lateral flight (or wind).
Bottom line, I am not sure you can do much about this behavior using gain settings. |
