That won't work unless the switch is rated for 100amps! Just about the best way to make a swith work would be to splice the red receiver wire (positive) and stick a switch on that (in series). This would be for if you use the BEC, as it would power down the receiver, so the controller can't get a signal. If you use an external receiver power source, then you could put a switch hooked in series with the positive wire.
