Just go into the settings and open throttle cut. It will be inhibited, so you need to activate it. Once you activate it, it should work properly without any other settings. It's the top left, furthest back switch. Pulling towards you will stop the motor. When you power up the plane, if your using an idle at bottom stick, and the throttle cut switch is on, you need to shut it off, turn it on, and turn it off again before the motor will run. Easy to get used to, but might trick you a few times at first.
