ok. I was uner the impression that the esc did not need 6v to operate.

I remember reading in the earlier RS days (before 1s support), that people would removed the red lead and the esc would only get 1s voltage from the main battery pack and everything else would get 2s voltage with an rx pack hooked up directly to the rx.

I'm going to be hooking up an rx in line with the switch. I was just exploring other options.
