Hello.
I am trying to learn how to operate a drone using ardupilot. I have 0 knowledge about this.
I’ve have Mission Planner 1.3.74 with ArduCopter v4.0.7 and CubeOrange.
Battery Failsafe means your battery voltage is below whatever minimum battery voltage you’ve got set.
Throttle below failsafe means the throttle value your receiver is sending to the flight controller is below the Throttle failsafe value and if you were flying this typically what you use to trigger a RTL.
What it suggests to me if you’re working on the bench, is you were powered up by USB and your radio isn’t turned on.
