Hello to everyone,
lastly I have bumped into a strange behavior after a few minutes of flight. I thought that the ESC were failing and changed them but the problem persist.
Auto Analyzer says there are problems with the compass and other variables. Nevertheless if you manually review the log you will find that everything works well until minute 6-7. This has happened in 4 flight attempts after making sure everything is calibrated and well adjusted.
Hopefully someone more experiment than myself can see something I'm not seeing in the log files attached.
Thanks for time! Any help is appreciated.
