That's what the throttle trim does! Perhaps you need to tell us what Transmitter you are using and IF it has trim adjustments. If it does, you adjust the throttle trim so the engine idles when the transmitter throttle control/lever is full off. You then pull the trim adjustment back which closes the throttle fully and kills the engine. We do this with our airplane engines. I think you need to learn a bit more about how your transmitter controls work.
