I don't like any of the pre-set Master Stick Modes (Phantom 3 Pro) so I customized one. I got it set up the way I wanted it and hit save. Then, when I went to fly, I couldn't get the props to start spinning. I took both sticks to the bottom outside corners and nothing. I tried the bottom inside corners and still nothing and so I tried the top outside and inside corners, but no matter what I did I couldn't get the props to start. The only way to get the props to start is to go back to one of the pre-set modes. Am I missing something here? Is there a step I'm missing? It seems like I should be able to set a Custom joystick setting and the copter props would start up as usual, but they aren't. HELP!!!!
