I had the Bebop drone from 2-3 years ago and it worked fine with my IPad. Haven't used it since then. I tried recently to use it. First, I had to get a new battery as the old ones would not charge at all. Now, I downloaded the new Freeflight Pro app. The drone's power turns on, and I am able to connect to the Drone's Wifi, but it keeps saying that it needs a skycontroller. How do I get this to work. I know its a pretty good drone, so I want to get it to fly.
