Yes, turn on the truck, and the transmitter. You should have 2 little round dials on the transmitter. One for steering and one for throttle/brake. These are your "trim" settings. You want to set the throttle/brake trim setting at 0(neutral) before you adjust anything, that way if it does need to be adjusted a little you can use the knob on the transmitter to trim it one way or the other.
