Schade Schade - but you have to warn against buying this model car if the buyer has a Digital 143, because the vehicle is a bad design and will not fit on this racetrack! the guide pin is as appropriate rear underbody that the RB7 encounters in the curves of the guardrails or inevitably collide with other vehicles! Furthermore Looping driving is impossible because with optimally adjusted sliding contacts these lose contact with the road because also touches the front wing of the car! If you compare the contacts so that the loop goes, hover the front wheels in the air!
So all in all a disappointing misconstruction, strong drive, but the chassis is shot!
