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.
