Digging all that green bling. You should get a batch of white wheels and dye them.

I currently have,

Zero boost
5 degrees turbo

Still learning about reciever voltage also.
Is a Savox 1258 a high voltage servo?
Read some about reciever capacitors but with a fan and transponer I'm out of ports. I could plug the fan straight to the SC or even the battery.

Almost makes me miss spec slash class. Almost. I can see how people might get discouraged with all the tech. Lots to learn.
I would switch to 24/76 gearing for Paul's place. Also you can take most all the timing out of the motor and only run about 8-12*. The motor timing and gearing is where your over heating issue is coming from.

Also no need to run any turbo at all for the small track you are racing on.

Depending on what rx you have the savox servo might require a capacitor.

You shouldn't need a fan on the motor if all your gearing issues and timing issues are taken care of. I ran 4 battery packs down there the other night almost all back to back and never got over 140*.

Thanks man!!
I'll try that exactly.
We're running a Spektrum DX3S and not sure on the reciever. Not high end stuff.
I'm still learning the timing stuff. Boost, punch, turbo, slope, lag, guhhh... someday I'll have it figured. Someday.

You can run the 3 line axle KYOUM510-02 and shim the assembly inwards.

Hey guys and gals, need some set-up help. I just got a RB6 and I am going to run it for first time this Saturday. Need a good set-up for medium to low wet some of the time and dry some of the time outdoor dirt.

Here you go. Don't have the car in front of me but I'm almost positive this is what I ran.

EDIT: Just noticed a mistake I made, running AE 1.6 pistons front and rear not AE 1.5's.

For the Tebo setups, does anyone know what brand oil he uses? AE, TLR, or KYO? Big difference between them all.

THANKS ROB! Has anyone had any experience with the RC Shox Dual Stage piston setups? If so what kit did you go with? I've been running the VRP products dual stage setup in my D413 and it rocks but I like the adjustable part of the RC shox setup better at least looking at it and reading about it.
