2. takeoff, hover 20 seconds, land
3. takeoff, go to a waypoint 10 meters away, hover, return, land
4. takeoff, visit N waypoints, return, land
5. takeoff, orbit via position control for N circuits, land
6. takeoff, use vision to see aruco marker, go to 4 compass points relative to marker, land
7. takeoff, use vision to see aruco marker, orbit via position control from vision target point, land
8. takeoff, go to a starting waypoint, then go in a straight line using world-frame velocity control
9. orbit a point using world-frame velocity control
10. fly in a box using body-frame velocity control (it will drift but that's OK)
11. orbit aruco marker via vision using body-frame velocity control
