Hey guys, I just got an RB6 and the rear of the chassis under the transmission got dented. I heard a rumor that kyosho america would send a replacement. Is this true?

Thanks!

Turns out maybe I jumped the gun as he isn't the original owner. Perhaps the original owner moved to the pink/red xgear or just put the color on the coil himself.

thought I'd post a pic of a RB6 Finisher body I painted for a local. The bodys lines are very nice. I like it.

Not technically possible. We can pm kraig and he can put info up, but there will be new info on a constant basis... it would be a full time moderating job just to update the 1st post on this thread... who knows.

You're correct, the RB5 SP2 WC came with Blues, these are between Pink and White, and you could only get them in the kit.
