Check servo saver to make sure it has not loosened up. If the servo is not trying to turn at all check the connection at the receiver. If it is okay, you can always switch the steering and throttle servos at the receiver to rule out the possibility of a faulty servo. They can fail if they get too wet or get hit hard enough.
