# Flight Logs

The DeltaQuad Evo records onboard logs containing extensive information about each flight. 

These logs serve multiple purposes, including flight performance analysis and troubleshooting. By examining them, you can assess the drone’s operational efficiency, identify potential issues, and make data-driven decisions to enhance future flights. The following three sections discuss how to retrieve the log files.

On the DeltaQuad Evo TAC/TAC+, more detailed logging on the flight controller is set by default to log without location data and is not encrypted. To turn this logging off or to set it to also log location-related data AMC must run in **Advanced Mode** (click 5 times on the **AMC Menu** to get the option)**.**

Go to **AMC Menu** -> **Advanced** -> **Storage** while AMC is connected to the vehicle. Note that this setting persists through vehicle reboots.
