RE: TB-02 Chassis
They're the better side of the Shaft Driven tamiya line up. Actually, from all the 4WD shaft driven tamiya cars, I think the TB-02 is probably the best, since it's racing spec. It's got ball diffs STOCK, unlike the TL-01, TT-01, and TB-01(which are all the 4WD shaft driven tamiya cars i know of, aside from the TB-02...), which have gear differentials, but can be upgraded to ball diffs. Also, I THINK you can get a carbon fiber chassis for it, i'm not sure. I may be mistaken with the TB-01, but either way, it's just much better than it's predecessor, the TB-01, and also the other tamiya shaft driven cars.
