Also consider the ElectroDymamic fiber optic kill switch. The system it fool proof and works like a charm. Nice to have the LED on the side of the plane to tell you the system is Hot too.

Its not as fool proof as you might think. I had one in my H9 Cap 232 using PPM and if I got the slightist radio glitch it would interrupt my ingition causeing a dead stick. The glitch was so small the it could not be seen. For a long time I thought I had an engine problem. After spending a lot of time on the fuel system, ignition battery and wiring and mixture, I disconnected the fiber kill and my deadsticks went away.
