Default Setting up dual batteries for Rx and Ignition

I'm setting up a 50cc IMAC type plane and am using a pair of 2600 LiFe batteries for power. My question is can I run both batteries to the receiver and also my optical kill switch for the ignition without problems? I know the traditional answer was to use a BEC for the ignition to isolate it from the radio circuit, but with the optical switch is that still necessary?

I would use an IBEC, an RCXL optical kill can also be wired to do what you want and power the ign through the rx bus.

What would the IBEC do for me that the optical kill switch won't? As I understand it, I'll have isolation for the circuits either way. So what is the reason for using an IBEC?

because the IBEC is designed to power and isolate your ignition as well as providing an optical tx activated kill.

While there's those that use the RCXL that way with a wiring mod, thats not how it is designed, its designed to provide power from a separate battery.

I did some searching and came up empty. What's the mod for the RCEXL kill switch?
