Ok so seems bird flys pretty stable, no oscilatiions or something else. I have a dumb question - is it possible to configure to position hold without GPS? I mean vehicle drifting in manual mode and I assume this OK but could this behaviour possible at least to reduce?
Another dumb question - in Quatos mode I can't take off more than 10cm, I wrote xml (Quatos Airframe Geometry) and some parametres grabbed from Ladybird frame. I even can't imagine what can cause this.
