A basic optical kill switch will NOT seperate your ignition from your receiver if you are using one battery, ahicks said above that he uses one battery with a opto kill im not sure what unit he is using but a standard rexel opto will not seperate a ignition from a rx using a one battery set up. Perhaps he can clarify.
I've been told they don't work before, but these, the ones I have, don't seem to be obeying that rule well. Both these systems have been run quite a bit and I trust them.
I'm using one 42% (basic) opti switch with power coming through a single diode so I don't have to worry about voltage. It's getting power from the receiver buss, which is fed by 2 6v NiMh batteries supplying power through 2 switches. It would work just as well if it were run by a single life, and I would go to 2 diodes for the A123. I'm using the 2 NiMh because I had them, I really like the idea of the redundancy, and because I'm running some 100 in. oz.+ digital servos.
The other setup is a little more off the shelf. It's from Syssa, they call it a "SAP Ultra IBE (Ignition Battery Eliminator) and Ignition Kill Switch". It features a built in voltage regulator, so you can run it as is with any battery chemistry you choose. The link is :

I'm not here trying to talk anyone into this. I heard others were doing it and decided to try for myself. Other than the wimpy NiMh battery chemistry lesson I experienced, I've seen no good reason not to continue the practice. FWIW
Wrongway RC continues to supply ready to go components if you're shy about collecting them yourself. I understand he's also very supportive?
