I have tried calibrating my Joystick's using the DJI GO App numerous time. After l draw an uninterrupted line for both joystick's and return to center it shows my left joystick at 9% and my right joystick at 4%. I then run my left front wheel all the way to the left and then all the way to the right it never says finish? I can click on done and that's it. If I run the joystick around the outside of the box a few extra times the calibration times out?
