Run a heavy pack on loose outdoor dirt tracks to generate more grip, run a light battery on carpet to reduce grip.

My real problem is space... I'm using a Nosram Matrix ESC, which i guess is quite large. I changed my body to a JConcepts one, and the wiring doesn't fit inside it, since the ESC was on top of the back battery holder. So i tried to put the ESC near the motor, the receiver behind the low profile servo but i think a shorty pack won't fit in there... Can you show me your layouts?

whilst this is not the perfect outcome just create a new post that you can mange, send the actual link of that exact post, not the page to Kraig and have him put the hyperlink in the first post.

that way you can update as required and everyone can easily access the info

Does the rb6 use same wheel as b4 or does kyosho have their own wheels?

Anyone use mid motor config in 17.5 blinky mode with success?

I like it. Am using it with a few tweaks. To me he sets his cars up very mellow and fit my style. I also used one of his when I had a 22.

Who runs the old front hexes for the RB6? If so why? Also how can someone use those while keeping the same width as the stock piece?

I run my old B4 wheels for now, but Kyosho wheels are better quality. Fronts measure out the same, rear B4 Jconcepts wheels give you a 1mm narrower track width each side, so the car will be 2mm narrower in the rear only with JC B4 hex wheels. I plan on buying Kyosho wheels and sticking with those for the rigidity/quality and correct offset.

Don't know about the stock wheels being rigid. Maybe the rears but definitely not the fronts. I switched over to the Proline wheels it hides the wheel nut all around and haven't had one bend yet.

Nope.. different wheels. Stock Kyosho wheels are money.

It's more about the track surface and overall traction level, then what class you run.
