He won the first two races, which allowed him to sit out the third (max points of 200).

I have to say this was my first full build of any car? I am about 75 % done. The only things left are the shocks and couple of misc stuff. Will say very easy build just took some time but thats bc I wanted to be carefull and double check I did not miss anything. When building the ball diff I did destroy the plastic nut while trying to remove it bc I could not get it catch the screw. I have the exotek one coming in a couple of days. any tips on the ball diff install?

At the roar nats they make you sit it out, so you do not interfere with the finishing positions of the rest of the pack.

Yeah...you already won. What else do you have to do? Good run for Tebo, his car looked good in the mains.

When you run tripple A mains, if you take the win in 1 and 2, you are done with 200 points... as your points only count from your "best two of three". So, Tebo takes podium spot #1 after A2. Running in A3 just gets in the way of the other racers competing for spots 2 and 3 on the podium.

Wow that was brutal!

Good to see the rb6 is more than capable, in the right hands, in MM. And the class was not won by an on-roader!

Though arguably the best rear-wheel on-roader right now.

He looked to have less motor than anyone. Naoto is a straight beast!

Auto zone. Look for rolls of rocker panel protector.

Re tebo's mm setup

Yeah me too. There's a body off photo on live rc and you can see he ran saddle packs. At least it's something till the sheet comes out.

On the weekend we had a big meet in sydney australia, 150 entries over 6 class, 2/4wd mod/stock and stadium/short bus 10.5. 33 entries in 2wd mod with about 15 of those top ranking in australia. We had 4 RB6, 3 22's, 2 D210, and a yokomo in the a final, with rb6 taking the win (black/yellow/white) and 3rd (white with pink wheels). I finished 9th and 1st in stadium(RT5).

The track was high grip with bar code style tires working well, but lots of bumps/ruts from 2 months of poor weather in the lead up to the event made it very easy to make mistakes (hence the club would have liked a few more jumps but ran out of time). The big drop at the top of the hill is called the cork screw
