Problem with yaw (quadcopter)


When arm my quad and take off, yaw stick not respond and it depends if turn right or left lose height or have more power.
I checked the examples for AHRS. Roll and pitch are a stable values but yaw come down.
I analyzed logs and RUD channel input and Ch4 output are working OK.

Thanks in advance.


Anybody knows how can I resolve this problem?
Main problem is yaw control don’t work. Maybe for calibration problem or wrong settings (PID) .
How can I do a hard reset for Navio2 board? Reinstall Navio2 image is enough? Or some parameters save in an internal memory?

You can reset yaw parameters in GCS. For example in MP there’s a Reset parameters button in Full paramater list that is available after Advanced option has been selected.
