I have two new gas engines that I have recently installed. One is a Zenoah G26 and the other is a US Engines 41cc. Both engines have built in magnetos. Besides the obvious toggle kill switch mounted on the side of the fusalage I was wondering if there are electronic kill switches that can be operated from the radio for these engines? It would certainly enhance safety when using the kill switch from a radio in the event of a runaway engine due to servo or linkage failure. I have a DLE35 in another plane that has this electronic kill and I love this feature for safety and convenience.

Someone made a transmitter kill that would ground the magneto for zenoah boat engines but I haven't seen them in years. The dujour of the day was a transmitter activated physical micro switch.

Or an electronic ignition conversion from (if memory serves) CH Ignitions
