When I first set up my tricopter, my tail motor on the KK2 board was showing ccw rotation, which was the way I wanted it. I have flown it once and it had some issues. So I went back to a factory reset on the board to start fresh. Now the KK2 board is showing a cw rotation on my tail motor, and my KK2 board will not arm. How can I set up the board so it will show a ccw rotation on the show motor layout function?
