Ok, my new RX8 is DOA. I can make changes via Hotwire, but after soldering it up to my SC10 4X4, no joy. I measured voltage at the ESC posts of 8.38v so I know the batt connection is good. There is no spark when connecting the Deans plug from the batt (2S). I tried several known good batts, no luck. With everything plugged into my receiver, there is no servo jump when turning the ESC on, and no lights on ESC or receiver. I unplugged everything from the receiver and still no lights on the ESC. I upgraded and down graded firmware, no change. I unsoldered the motor (Pro4 4600) still nothing from the ESC.
Time to get an RMA?
