Aren't Novak's wired a little differently? I remeber reading in their instructions for their HV Maxx controller that if you run a single pack (like a 12v or a 4s) you can't turn on the ESC when you run it, otherwise you'll burn up the ESC. You have to run an external ESC or rx pack. Never mentioned unplugging the red wire, although I'm assuming that this would work too.
I guess thats all you can do. Thats kind of why I started the thread. I was hoping that there was a way to actually turn off the BEC and power the ESC circuits with the receiver pack or UBEC.
