setting up servos and throttle with the radio should be done with radio left alone(factory settings) on adjustments until you have the steering/throttle working. only after they are set should you "fine tune" these with the radio. only diff is setting up the speed control which is done the same way but follow the speedo instructions. once done, it is very important to set the epa on steering and throttle if gas. messing with features that you don't know anything or understand what it does can be bad and only make things harder for you..ask someone at your local track to give you a hand, then they will also explain what thing do if you choose to mess with a setting..
