New X8 having issues

Having an issue with my 3DR X8. See youtube video. There is no wind. Every so often aircraft just goes a bit crazy and loses it stability. It has been getting worse and worse. I’m going to go through and recalibrate everything. Anyone else have an idea?

Please add a log file

Thanks Gary. I am new to all of this. Did some research on how to download log files. The date and times on log files didn’t actually match up with my flight times.

A number of them seem similar to the one below with a fail for the compass. I have recalibrated the compass. Is there anyway I can see if it is successful or not? Do I have to go out to the field and do another flight then check log? I might clear out all logs and then see what I am dealing with with log number 1.
