The suspension is adjustable for speed and the conditions of the chosen trail and the flexible nylon elements allow a new building experience. The 3 channels make it possible to race against other cars. As it includes batteries and a charger theres nothing extra left to buy!
It also has adjustable suspensions (front and rear) for speed and off-road conditions.
It comes with a mains charger, 7.2v Battery and a 9v Battery for the remote, which has gear shifts. It also comes with 3 adjustable channels, so you can race 3 cars at once without interferance between them.
One other thing, it is very fast and great fun to drive. It is much faster than LEGO's previous R/C success, the LEGO Racers Supersonic RC - 8366. At least 10 times faster, I would say.
In my overall opinion, I think that this Lego Racer is Excellent for what you get. A must for anyone and any age.
