Disco connection to controller

[sladl11]

Hi there, can anyone assist with connection issues?
I have a now recurring issue with the Disco unexpectedly losing connection to the controller.
After reading online, it SEEMS like the connection is made using wifi only. Is this true?
Thanks

Seems like the Disco just randomly loses connection to the controller and flies off regularly. Other blogs have pilots that carry a modem with them to maintain connection.
