Tebo usually uses Losi oil.

I know this can't be the first time this has come up.
Anybody? Nobody has lost a cvd pin?

So ready to pull the trigger on a RB6. Coming from a DEX210 that I struggle with lack of steering, everyone else seems to turn tighter and with better corner exit.

Seeing the common setup sheets online it seems the consensus is mid motor. I run on a small-mid indoor clay track with medium traction -- sometimes high.

Is mid motor the way to go with this ride? Is the Tebo WC setup one that I should build from initially? What are the characteristics of MM for the RB6?

DEX210 in mid motor just wasn't popular in the US unless it's high traction clay or carpet, and most are running RM3 at my local clay track. Is the RB6 most efficient in MM.

Thanks for the help. Looking forward to building one soon.

The rb6 is a beast to drive MM, way better then my dex210.
Personally id start with Tebo's reedy race setup and adjust from there.
One of the tracks I run on is a small indoor clay track and that setup with Super soft handlebars rear and ions up front the car is money.

Thanks Ventura. I've never driven a MM before. Did you have to adjust your driving style?

I know the MIP and Kyosho barrels and pins for the cvd are not the same size. Sorry I can not be more help.

What are people recommending, Tebo or Cody King's Reedy Race setup as a starting point?

Try both they are equally good. I feel Cody's is a touch more neutral to drive.

Yes, I'm not able to hammer the throttle quite as much coming out of the turns but I can carry over all more corner speed so overall I had to learn to drive less point and shoot and more smooth but my lap times show that even tho it may seem slower to me I've gained near a full second a lap.

Thanks... I will start with King's and experiment with Tebo's to see how I like it!

I mean this in no way as a knock on Cody King but I was very surprised that someone who is known way more as a nitro 8th scale driver came up with such a good indoor clay 10th scale track. Props to him.

The only difference that I see between king's and tebo's setups is that Cody is running 2 deg anti squat and no shims between steering piece

The stock pistons holes have been discussed in detail in this thread, if you search "stock piston hole " size you will probably find it. IMO, for this buggy, the 5 holes do not have enough pack for a track with even medium sized jumps. The Kyosho 4x1.3 are pretty good but I think 2x1.6 are good too. It has been debated that the Kyosho 6 hole pistons have more pack than the 5 hole due to the hole size being more important than the quantity.
