Throttle Cut Switch

This function assigns the Throttle Cut switch to the push
button located on upper right front of the transmitter.
The Throttle Cut function is designed to return the
throttle trim to the lowest position instantly and keep this
position while the button is pressed. This feature is used
to "cut" or stop the engine without changing the position
of digital throttle trim.
