OK, here's an update on my kill switch.

Firstly, I don't have a choke on my engine, so activating it isn't a possibility. Secondly, I can't kill this engine by closing the throttle. It just wants to run forever. It got down to 800 RPM's and STILL kept running!

So, I went back to my kill switch idea. I mounted the micro switch 8" away from the servo, and as far away from the Rx as I could get it. I used a Sullivan plastic control rod to activate the switch, and made some braces from light ply to hold the plastic rod in place.

Success! The kill switch works just like I wanted it to, and this time with no glitching! Thought someone else might benefit from my original mistake. If you are going to set up something like this, you HAVE to keep the servo separated from the wiring. I imagine the farther away, the better!
