Need help, I installed RX18 board and all new wiring (double checked) with an inline fuse, everything is working fine except forward/reverse and left/right are all backwards on the radio levers. Any suggestions? Its the 27 mh type. Also, I need to get a set of 4:1 gears boxes. Anyone know of a reasonably priced outlet for that? Or even a set of used ones.

Thanks, Freddy
