The logs are in the folder var/logs.
Have a look at the wiki to see how to use the log plotter:

I have the same problems with ardrone and considered missing
configuration of magnetometer before the flight as potential
reason. However did not yet analyze it further.

When you say it flies fine using QGroundControl, do you mean with
paparazzi or another flight controller?

Do you have flight logs of the crash?

Also, airframe files (etc) might provide more clues.

Well? Any suggestions?

Specifically - is there a way to enable logging in the firmware
running on the UAV? Any way to know what "normal" telemetry should
look like, so I can begin to understand why paparazzi wants to roll
the vehicle to the right, even if I'm holding it level?

I don't have a joystick attached to the laptop during the flight.
Could the system be using a default value for the joystick reading in
that case?

In short - what's my next troubleshooting step?

     I've been trying to get this to work for a while, and I seem to
     have hit a wall. Or rather, the ground.

     I modified the rotorcraft_basic plan to get started, rather than
     create a brand new flight plan. The waypoints show up in GCS in
     the correct location on the map, and I can upload and start the
     firmware just fine. I get GPS lock and the PFD updates when I move
     the drone around.

     The problem is that immediately after taking off, the done rolls
     sharply to the right and slams into the ground. Not the ideal outcome.

     What might be happening there, and how can I diagnose what the
     drone is trying to do? It flies fine using QGroundControl, mostly.
