I just got some new radio gear for my xxx-nt adam drake and I know this is a stupid question but when I try and install the servo I cant get it in right so when I press the throttle it opens the carb, the only way I can get it to open the carb is when I press brake. It then closes when I press gas. So there is something that needs to be reverse right?? Well can someone let me know what I need to do.
