I have one I'd sell for half that. Barely used.

Are you running the same front tire choice or similar as everyone else?

Im running mid motor on a medium hard packed clay track with medium grip and I'm running the exact tires as everyone else just no one has an RB6

Hmm...I don't remember the kit setup but take a look at Kevin's setup and compare the differences. Click here.

If I go that route I will get in contact with you, but as it stands right now, my car is so good I don't want to throw crap on it and make it crap. My B5M which was barely above roar minimum weight kinda handled like crap. My RB6 as it stands now is only 1550ish. Too light and I don't like the way any car drives.

Light chassis, pucks, cut gears and all carbon parts I'm ready to run weight is below 1499 by a lot. I always have to add weight to make 1499 with full sized electronics.

So those of you running the sideways battery, how are you making your battery stay in place?

I purchased one of these and made new holes for the battery tray.

Works for regular shorty or the lighter 3000 mah lipos. The only problem is that it can be a PIA when you are trying to figure out where to mount it. It has an adhesive back but I used gray double sided tape.

Hi guys, do you know if pro-line rear premounted hole shot tires 8206-15 fit rb6 ? By fitting I mean about the same dimensions as with Kyosho wheels. Thanks in advance.
