I honestly can’t tell you where the drone went...but I looked at the data, and your friend had three significant issues within a minute of take off. Excessive voltage deviation across the battery cells, IMU compass failures, and a stuck controller control dial.
First observation..if u see these faults...land immediately. Not joking. Your aircraft cannot find its way home.
Now, I suspect something was amiss, causing an intermittent extreme power draw periodically. Whatever it was, and I have my suspects, I’ll speak to a little later...it may have caused such an internal power spike that the dc power conditioners specs were exdeeded causing Compass/IMU failures.
So this explanation to this point covers two of the three error messages...The las warning message was the stuck right control disc...this could have been the source of the power spikes causing the excessive out of spec periodic battery cell voltage deviation. Can’t know for certain...but definately a suspect. Two other possibles, or even coconspirators, could be a motor was acting up or a transmitter, or both...reason is , it was such a high over spec, I’m likely to think it was something with some real amperage draw, genetically speaking, your RF transmitters, motors and camera gimbal are the obvious suspects...the right control disc has gimbal involvement.
Now, only the operator knows when the drone became unresponsive and how many times, but it looks like there was ample warning to put it down within 1 minute of takeoff...even if your friend didn’t know what was wrong. My personal takeaway from this will be, quite simply...never ignore the warnings. Sorry I get to learn that from your friends bad experience, but in a small way her loss is going to help me, that’s for sure.
