The drone took off and flew like crazy

The drone took off and flew like crazy.
I want to know the cause

Log file

Z axis vibrations are too high

Motor Outputs are all over the place

Remember to mention as much information as you can when you post a log
FC, Propeller size, Motors, ESC, etc etc, all that basic stuff

Why not using EKF3?
Flash latest firmware and reset params to default and start from scratch
Follow the tuning guide

Thank you for your advice.

You are on default parameters, you are using an old version of firmware and likely the wrong one (fmuv3). If you have battery logging configured correctly voltage was down to 6.5V.
