Here is an update from me.
After I upgraded to the latest firmware 2.25 there are incidents which are weird.
I calibrated compass like 5-6 times at 2 different places, 20 meters from my car in the grass field, mobile left in the car, no metal object on me, and no change.
Here is what happend last time I flew. First battery was OK. Then on second battery I raised H and move stick to go forward but it moved forward-right (no yaw movement, just went forward-right). So I immediatelly stopped and in this moment slide occurs to the right in a circle and finally H is stabilised.
So I inspect telemetry data and find out that telemetry showing that I moved yaw from 160 to 200 which I DID NOT ! I just moved H to go straight forward but it moved forward-right. Then in the moment where I stopped (all controls to neutral) error_flags showed value 32 in duration of just 1 second.
Then I searched throught remote file to see if it record of any yaw movement and I found that CH 3 did not moved and it was in neutral 2048.
In all flights (about 20) before this upgrade there was no such incident, no incidents and weird behaviour at all.
