I am working on a “Instructor Station” plugin for MAVProxy - and have discovered some shortcuts.
Using sim_vehicle.py - the plane flies fine also at only 3v … the lower the voltage goes, the higher the throttle demand increases, resulting in better thrust/speed.
The problem is that thrust is calculated only by thrust demand, and voltage/current is ignored.
One would expect that a required power (watts) was needed for a given mass and drag
And then voltage and current should behave realistically based on the internal resistance the virtual battery.
