A simple QuadPlane model is available in SITL, allowing you to test the features of the QuadPlane code without risking a real aircraft.
You can start it like this, from any vehicle’s subdirectory:
sim_vehicle.py -j4 -f quadplane --console --map or add the vehicle type: sim_vehicle.py -j4 -v Plane -f quadplane --console --map
If you have simulated other vehicles in the current directory, you may wish to add the - w option to the command line to reset the parameters back to QuadPlane defaults (normal Separate Lift Thrust (SLT) QuadPlane in quad configuration).
To visualise the aircraft you can use FlightGear in view-only mode. The simulation will output FlightGear compatible state on UDP port 5503. Start FlightGear using the fg_plane_view.sh scripts provided in the Tools/autotest directory.
Note that to get good scenery for FlightGear it is best to use a major airport. I tend to test at San Francisco airport, like this:
sim_vehicle.py -L KSFO -f quadplane --console --map
Using the joystick module with a USB adapter for your transmitter gives a convenient way to get used to the QuadPlane controls before flying.
If flying at KSFO there is a sample mission available with VTOL takeoff and landing:
wp load ../Tools/autotest/Generic-Missions/KSFO-VTOL.txt
As usual you can edit the mission using “module load misseditor”
