The Red Bull is very visually appealing. From the processing I have to say that an outside mirror is broken off after a few accidents already and the rear wing fell off. But this was infected again. And now the main gripe with this vehicle: the Fahrbahrkeit. it is quite difficult to find nothing but the best grinder settings. Are they too shallow it will not make the looping, they're too steep, he slips out of the curve. The wedge is unfortunately too far back attached, ie curves in the front wing is too far in the adjacent lane, which is why it always comes back to accidents with other vehicles. Since the car was at the track there, I could not return it, unfortunately. Addendum: Have now made in this respect also experience with the Carrera-sales service. Just great !!!
