The SparkSwitch is a reliable high-performance ignition switch. The switch if operated from your transmitter, I prefer their “safety” setting where you need to alter the state of a switch or channel back AND forth in order to change the state of the ignition.
Keeps you from accidentally switching the ignition on or off. You always need to confirm your intent this way. All you have to do is set up your radio control transmitter for use with the switch.
