No reverse!
 

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?

Hotwire makes this much easier to do - personally, I just swap the diffs rather than reversing the motor.
