First gasser....how do you hook up the great planes kill switch in relation to the throttle rod? Any pictures?

If you hook up a kill switch to a throttle rod you could accidentally kill the engine at the wrong time...Most gassers are set up to use the idle trim to completely close the throttle, killing the engine...The black wire on the source coil will kill the engine when grounded..I haven't seen the Great Planes kill switch, but it most likely takes a separate servo controlled by a switch on the transmitter....

Thanks,
The great planes kill switch has an off/on slide switch and a micro switch. A friend suggested I use a wheel collar on the throttle rod and mount the switch on the exterior f/wall.
