Hi
im just have trouble with my hexa acro copter. Attached the logs which are showing Baro and EKF errors.
Today i was having also a big crash for no resonable reason, the logs are Attached.
Could somebody help solving ?

It appears from the auto analysis your battery was low and PH went into FS mode.
It records the crash.
The vibrations IMU are WAY too high. You might check those on a previous log as well, to
see it this is a new or old problem. If it’s old that needs to be fixed now…

Hi,
the vibration level on this copter is pretty good, the values shown by the auto analysis are coming from high dynamic flying. 10G = really fast and a lot of fun. 
The copter is very fast and flies high dynamic, speeds up to 60mph or 100km/h.
I’m looking for the Baro and EKF errors included in the logs, what could be the reason for ?
The flight ended abruptly while flying upside down, doing some acro figure. the copter suddenly was not accept any pilot inputs anymore and crashed. In the logs there are simultaneous Baro and EKF errors.
