position to stop an engine or motor. Throttle Cut activates
regardless of Flight Mode.
When you activate Throttle Cut, the throttle channel moves to the
pre-programmed position (normally Off).
You may need to use a negative value to move the Throttle channel
to the off position.
CAUTION: Always test the model after making
adjustments to make sure the model responds to
controls as desired.
You can use the Throttle Curve menu option to optimize the throttle
response. A maximum of 7 points are available on the throttle curve.
