Hello, What do you think would happen when during a flight the powersupply for the controller would run empty? * would the quadcopter start hovering? * would it start descending? * would it keep on flying? * would it return to the startpunt (for GPS equipped drones)? * would it be possible to insert a new powersupply andere reconnect with the Drone? Quadcopter concerned is the Yuneec Q500+ 4K. Thanks in advance.
