Hi,
With our Ardupilot quadcopter version 4.3 we made a crash. After we took off we lost rc communication and then normally flight mode became failsafe. After that somehow we lost control.
I shared logs (.bin) and imported log files to auto-analysis but couldn’t address the real problem.
Can anyone help to understand the results? What are we missing & why the autopilot couldn’t control quadcopter?
Thanks.

Hello,
this report isn’t usefull, we need the full .bin logs to look at the data for what was wrong.

Uploaded again. Thanks.
Update to the latest firmware.
There is no battery voltage or current in the log file. A good idea to make sure the battery monitoring is setup for both current and voltage.
Setup notch filtering.
The tuning parameters here are strange. Typically ATC_RAT_xxx_P and ATC_RAT_xxx_I are the same. There are significant enough oscillations in both pitch and roll axis to validate this tuning is not good and should be re-done according to the wiki.
