after calibrating compass, gyro and accelerometer, i tired 'Level Horizon' but the only message i get is:
Start the individual calibration steps by clicking one of the buttons to the left.
[cal] calibration started: 2 level
attitude estimator not running - check system boo
[cal] calibration failed: level
can someone help point me to the solution?
another point: Airspeed is also red, but i have no airspeed sensor. is there a way to disable 'airspeed?'
