What if you never put the shim in between the tower lol

Get the flat arms (um521-1) and the short shock ends in the rear. Best thing you can do to the car in mid or rear motor, period. Screws are "mid grade" at best, and the plastic is kinda "sticky", so take care and use good tools as it is very easy to strip those 2mm heads.

I really like the 4x#55 pistons -- you can get losis or drill your own by hand.

I would then start with either a rear or mid motor applicable Tebo setup from http://www.petitrc.com/setup/kyosho/...UltimaRB6.html .

Adjust tires, camber, and shock oils for your track and you should be golden. If you're on reliable good trip that doesn't get slick, mid motor is a good option. Start with -1 camber all around unless it's super stuck, then consider -2. If you're on a track that gets slick, rear motor is my preference. Same suggestions on initial camber. Adjust shock oil to temp, taking care to use losi oils and maintaining the front to rear difference that Tebo ran initially, and then tuning as you see fit.

For example, I run his nats setup with #55s, pink/gold springs, 35 losi front, 27.5 rear, -1 camber all around. It's hooked on medium/low grip indoor top soil.

Jared's setups are always a great starting point and are always really close with perhaps shock oil or camber needing change, and of course, correct tires for the track.

Here's a link to some pics of the pair of full option Yaiba cars I mentioned a few days back. Tomorrow I get to deliver them to my buddy and help him break them in on the track. Nice build overall and thanks to you guys for the various tips I read in these pages. http://www.rctech.net/forum/12616326-post100.html

Would you please measure the width of the flat sides of the pucks? Or the gap in the pucks outdrives? I am planning to put touring car blades on my MIP diff and so I would just need the pucks outdrives if the width is correct!

they basically sweep the axle forward to create a different weight distribution.

Well now I'm glad I posted pics. I looked at pics of Tebo's car from CRCRC and really couldn't see it clearly. Guess I should have checked his Reedy Race setup as it clearly showed the arms the opposite of how I mounted them. First Kyosho build. Looks like I have a little more to do tomorrow.

By the way, your buggy looked really good on Friday. I was shocked to see how well the MM cars are running up there. We'll see you up there soon!

I run the GHEA 4x1.3mm pistons in my rear mount and really like them and the way the car felt is so much better.

I have to get some more for my mid mount carpet RB6 but was thinking of trying AVID pistons but was wondering if they need shimming at all as I read that the #55ís Losi ones do?
Mind you the money between AVID and GHEA isnít much

Looks like I will be starting again with trying kit arm V flat arms as I never thought of running the shorter shock ends until tonight.
This will now allow me the adjustment I needed to get my ride height down for the place I race on carpet

They run them that way in Europe in some places.
Better in slicker/low grip.
