Designed exclusively for gas engines that utilize a CDI (Capacitive Discharge Ignition), this device will provide a convenient and safe way to switch the ignition box on/off from the transmitter.  Most importantly it is fully opto-isolated, which means that the output of the circuit is insulated electronically from the receiver, so the high-frequency pulses (spark) created by the ignition box cannot back up into the receiver and cause interference that might compromise your model.  It features an on-board regulator that makes it compatible even with HV (high voltage) receivers using 2S or 3S battery packs.  Also included is a remote LED to indicate when the CDI is "on".  This unit is programmed to cut the power to the CDI box if the signal is lost during flight.
 
We recommend that, for safety purposes, you connect your Opto-Isolated Kill Switch to a spare channel that is activated via a switch on your transmitter, and that you also use a separate switch, like one of our HD Switch with LED, to disconnect the battery that powers the ignition box.  This will give you 2 layers of safety, an important consideration when dealing with a powerful gas engine.
