Chassis looks very nice!
I like how simple and open they've kept the chassis plate, it makes it very easy to try out various layouts yourself without doing any sort of modifications on the car!
I have to say, I even really like the shell except for one thing... Why not make the edge between the roof of the shell and window a bit more rounded? It would've made cab forward bearable for me, I'd even support cab forward if they'd do so!
As for the price on Kyosho.de... I hope they're kidding, right? That buys you a lot of different stuff from the competition, and I'm not convinced (yet) that the RB6 will be that revolutionary to justify this kind of difference in price! That said, this is another one on the list of cars to watch!
Really, if Tamiya doesn't answer to this soon I consider the chance to drive Tamiya again after my 201 has had the best of it's life very, very small! (DEX210, SV2/SVR, RB6, a conversion of sorts... And if they ever release it a B5, the non-metric hardware and the horrid styling on every chassis part is enough to keep me away from the B4/B4.1).
