After my black box had set the function that consideration was natural to add itself a Control Unit for the Carrera track, so that we can take advantage of the new features soon. At first I was skeptical because I had read the reviews of those who forgive one or two stars. But as I continued wanted to race, I gave up the order at Amazon and 2 days later, the Control Unit was my own. I had luck or Carrera has responded? In any case, the diodes "ebenbahnig" and "clacks" not. Gone are the days, had to be raised for each program in which the car for a double or the controller is plugged into the appropriate socket. Braking, top speed and fuel level are now confortable from the Control Unit to operate. Granted, if you use the lap counter and the new CU, there are two start / finish lines, but I can live with. I'm curious coming up on the new "realistic" tank function.
