Increasing the flight distance by Parrot Disco?


Product: Parrot Disco
My Question is: how to increase the flight distance of my device?
Perhaps there is some way to disable ( at your own risk) the control of the distance in the “flight plan” ? How to do it?
Earlier (in 2016, when I bought this device) - in the “flight plan” it was possible to launch the wing at a longer distance , after agreeing to the risk.
I understand that the signal remains between the console and the wing is only 2 kilometers away, however, before he could produce uncontrolled flight, and once in range of 2 km. is the connection returned. Tell me, how do I fly on the wing, a distance of more than 2 km?
