I hooked up the RX8 combo last night and the motor rotation was reversed. I set it to setting 7 (which is supposed to reverse the rotation) and it did reverse it but now I have no reverse. It runs forward fine and brakes fine. Setting 7 spec is Reverse rotation motor, brk/rev delay. I went back and forth 10 times between setting 3 and 7 and it repeats. Recalibrating the ESC did no good and it would not calibrate with the radio in reverse mode. Where's the reverse for the setting 7?
