Stall Warning
Stall warning is a configurable warning message.
It can be set in Config. Tool.
Just Set the speed that you want MinimOSD-Extra to warn you. It is depending on your units of measurement setting.
If you have set metric, than it will be in Km/h. If you have set imperial, than it will be in mph.
It works this way:
1./ If you have airspeed sensor:
It will refer to your airspeed
2./ If you are not using airspeed sensor, it will refer to your ground speed.
If your speed is less than 4 km/h than it will not show up.
