Hi John, Are you logging some signals on your Simulink model? Is MAT File logging enabled? Also you are looking up at the old documentation pages. Please use the new Documentation

I thought the MAT-file is needed for doing the modeling the drone? Do you have a link to the "New Documentation"?

What am I missing when it comes to the Mat-file?
