I have attached the BIT-Switch zip file which I got from http://www.rc-cam.com/projects.htm it is copyrighted and only for hobbist use. Please read the PDF. Let me know what you think? I'll upload a schematic and board layout after I build a good one, as soon as I get a chance.

For what it's worth, guys, I've used this same type circuit, but with my own personal programming, as a kill switch on my gas engines for a long time. My version also looks for a loss of signal, and kills the ignition if there is no valid signal coming from the Tx/Rx. The option labeled "[S1] Isolated On/Off Control" uses an opto-isolator (AVQ212) that will successfully separate the receiver from whatever it's switching. You may need to update that part number, I think the AVQ212 is discontinued, just search Digikey for a newer part.
