What to do if my FMS 1800mm Ranger aircraft will not respond to the throttle?

If your FMS Toy aircraft isn't responding to the throttle but other controls work, it could be that the ESC is not armed. Ensure the throttle stick and throttle trim are at their lowest settings. Alternatively, the throttle channel might be reversed. Try reversing the throttle channel on the transmitter.
