I looked into this a year ago. I bought a BK2 losi as it was better built IMO. I still managed to snap the little thing in two, like a twig. I much prefer the older metal RC10 for looks and toughness. I found it pretty cack in damp weather too - spinning out too easily on power. I wouldn't ever buy either a 2WD or a carbon chassis car again. I'll be sticking to 4x4 and metal chassis from now on. (Maybe I'm a pants driver, lol)
