Now a test flight , my Pixhawk has entered into a Fail-safe EKF - 1 minute 2:12 appears for no reason .
After that time , the controller did not work properly until you have not regained control manually.
When connecting to the PC controller showed me these failures:
PREARM ACCELEROMETERS NOT HEALTHY
BAD GYRO HEALTH
I think it could be error SD card, but when I changed to another card, continued errors .
After recalibrate all sensors, now apparently works well , but I fear that the problem happens again .
Any help is very much appreciated. Regards .
