This part is really a fun device and it is also almost indestructible. My Junior has been standing with its approximately 13 Kg on it and nothing happened. All suspension parts are mounted very elastic. Falls do no harm. The tires (foam rubber) have a lot of grip.
Who wants to go to the racer out there, needs to have a very smooth road, otherwise jumps and flips over the "Small". In the apartment, almost anything is possible if you build just the right hill of wide or high jumps.
The description says, it takes 6 AA batteries for the transmitter, but only 4 pieces will be needed. The station still has a special function, the flip mode. (Position detection for rollover)
Loaded is the transmitter, it takes about 10 min. And you can then, depending on driving style drive about 10-15 min. But as every other experience will make.
By 2.4GHz technology, several cars can be driven at the same time equal.
