Would I just have to splice the battery wires having one go to the ESC and the other to the EDU RC or is that in series? If you have a link to a wiring harness similar or a diagram that would be much appreciated.

Also for the BEC I know its on the ESC but is it also on the EDU RC? Does 7.2 volts come out of the EDU RC PWM Outs or is it 5.0 volts. I needs to be 7.2. Thanks again!
