they rock.
they are sold at radio shack in the USA apparently to compete with kyosho mini-z. they go the same speed(ish) as a mini-z but the speed and steering is not as proportional as the 512 (odd) steps in a mini-z.
the good part is that you can buy body kits for them... they look fooly sic moit!
they are only 1/2 the priceof a mini-z too.
my only problem is they tho you can buy a honda civic (which looks really cool, they are erar wheel drive and to my knowledge civics are FWD.
but if in the US, give them a shot.
