xxsnookxx,

I convert all my ignition units to standard JR connectors so that any battery, switch, regulator, or Ignition Cutoff can plug into it.

I've always used the Smart-Fly [link=http://www.smart-fly.com/Products/Ignition/ignition.htm]Ignition Cutoff[/link]. It has a small unit that you include in the line between the ignition battery switch and the ignition unit, and another small unit that plugs into the receiver channel. The two are connected by a fibre optic cable so that no RF signals can travel down the line to the receiver.

I've seen guys use this Optical Cutoff as their ignition switch. The ignition can ONLY be on if your reciever is on and that channel is sending the "on" signal. Seems like a very effective switch. If you run a setup like that, you have to unplug the ignition battery if you aren't going to fly for several weeks because it does draw a little power.

You always need to pay cloase attention to your fail-safe position for the "kill" channel. If you want the engine to die in a fail-safe situation, you have to program the "kill" channel to go to the "off" position for fail-safe.

Let us know if you have any questions or need any other information.

Take care,

Dean
