Like was mentioned already, the ESC would have to be powered so that the BEC could power the receiver. Then, you could use a small relay to arm the ESC (using the switch wires). To do that, you'd need a device that turns the output pulses of a receiver into an on/off switch (can use a modded servo, modded Losi starter module, purpose-built device, etc).

To have a true on/off system, the device would have to switch the main power leads, which means you'd have to find a way to power the receiver with 6v all the time (via external BEC) and then find a device that is rated to switch at least 200A. I suppose you could come up with a switch module that is basically made up of several FETs in parallel and drive the gates accordingly (essentially one phase of an ESC).

But really, what are you gaining from this?
