I'd be genuinely cautious about the rascal. Schumacher no longer produce it, and haven't for some time.
This would make it epic tricky to get parts for after a while.

Consider something like the HPI firestorm, Traxxas nitro sport or traxxas rustler, If 2wheel drive stadium trucks are your fancy.
If you could be convinced to get a 1/8th buggy, and i'd genuinely suggest it, then try something like the Hyper seven, Ansmann Virus 2.0 (Make sure it is the 2.0) or hpi trophy.
