Hi guys, the copter was performing okay, I have extremely borderline Z vibrations.
The copter managed to do an auto flight which involved loitering and waypoint following.
I’m not sure what happened right at the end, could you please shed some light on what could have caused it to drop from the sky? Did I fly too long, with the battery failsafe turned off, and run outta juice?
No major damage, ground was soft 
Kinda new to log analysis. One way or another i’ll be trying to get those Z vibrations under control.
Pixhawk is awesome btw guys, looking forward to 3.2
