For confirmation, when you say longer ball studs you are talking about using ones that have a longer threaded part right?

Are the gold springs recommended for front and back?

Hey guys I just picked up a RB6 yesterday. For those of you that have well setup RB5's have you kept it or sold it? I'm thinking of keeping my RB WC SP for stock and run the RB6 in mod. For those that had both do you feel that the RB6 is quicker than the RB5 in stock and mod?

Thanks everyone for all the great build tips and setup information! I can't wait to drive this thing

Yes there are 3 Kyosho standard studs.

There are the short black ones that the kit comes with. I have replaced all of those with medium, or long ones.

To figure out what the medium ones look like, they are the same ones that go on the steering rack portion. They do look a little shinier than the longer ones.

I have put long studs on the rear bulkhead, and I also use them on the outside rear hub. I have also replaced the black ones on the outside front hub with mediums. They do go though a tick, however they don't touch anything and since we can now shim that area it makes more sense to use more thread.

With the RB5 we pretty much had it figured out, and I can say I feel more comfortable with the 6 and I've only run it on 2 race days. If I kept my RB5 I would have used it for stock maybe since it's lighter (I think?) but I can honestly say the improvements over the 5 make weight a non-issue for me. It's just so much more stable and still turns.

Thx for the feedback. How much heavier is the RB6?

This may have been asked alreday, but I haven't seen it yet. Does the RB5 rear aluminum hub carriers work on the RB6 or do they have different ones?

They work fine, they did not redesign the rear hubs from the 5 to the 6

I only got one a4 sized leaflet (moving the front bulkhead studs to the other hole), is there another? Can someone kindly scan and post? Thanks,

Barely if anything at all really from what I gather. The best thing is that the weight is where it should be so its actually a benefit

Kevin, do you run the Orion wts battery or a full size? And if so have you added any of the weights to it?

Only rear, Pink fronts are still the way to go up front.

Only the standard shorty, no weight added.

If I can find mine, I'll post it. It is the addendum that tells you to shave down the turnbuckle that attaches to the servo horn. If yours clears without hitting anything like mine does, you don't need the sheet.
