This started only yesterday. Nothing happens when I push the sticks down and in to start the motors of the mini. However, I can start the motors and lift off by using the Take Off button in the Fly app. The same thing occurs when I try taking off in Litchi. I can't take off with the sticks but the app TakeOff function works. I have tried re-calibrating the controller but that didn't help. Anyone ever have that issue or know the best approach to solving it. Thanks.
