The second one is butter. Mine bent too easily.
Don't get it in the kit form instead order 6 of the thicker 3.5mm version rather than the 3.0mm. http://www.amainhobbies.com/product_...-Turnbuckles-4.

Do not go for the longer ones they will not work with the kyosho long ends. You will have to order the shorter ones instead from kyosho for the lazer or something.

I just ordered mine directly from lunsfordracing.com

You need a total of 6 1 5/8" titanium turnbuckles. Your choice of 3mm or 3.5mm.

Need recommendations for a 'base' setup, will be using my RB6 at WCRC and a smaller, more technical high grip local track. Is this the 'Japanese Setup' that is popular?

I'm looking at picking a rb6 up soon, I drive a b4.1 currently . Is this car agile like the b4? I wasn't a fan of the 22..

Hey guys, be careful when you put any clay in the area. I did that yesterday and I end up putting too much (how much is too much to start with??). When I screw them down, the chassis balloon out!

I tried the RB5 T plate piece, (I'm running the car in mid motor config).
Even with a thinned down T piece, the chassis was balooning out, and so I have decided to not run the insert, but will be running a lexan plate underneath the rear.

The material is so thin in this area is so thin you can flex it easily between your thumb and forefinger.

Interesting to know Chris, I was looking at this option during the build. I may just get my DB1 out instead!

Start with the Tebow set up with the kit rear arms. Change the shock eyelets in rear to the long ones. Shocks are Losi 55 pistons with 30 wt front and 27.5 rear.

Drew Muller will be posting his WCRC set up shortly but it is close to that.

There are a number of setups available for WCRC, I recommend not starting with the Tebo or the Japanese setup. Instead Cody, Drews, or my setup will be better for you to start with, all of which are or will be available on Kyosho's website.

http://www.kyoshoamerica.com/Factory-Setups_c_842.html

I have a slightly updated version of my setup on my site as well.
