Rustler VXL Setup

Hi guys,

Been reading RCM for some time now and i took the virus :)

So i bought myself a rustler vxl roller. I've always wanted a RWD.
The build is pretty much on a tight budget, for now, so i've settled on Kershaw's 80A combo (the EzRun and Revolver S).
I have a 76T spur, and was thinking of Robinson's 72T steel one.

What would be a good top speed to gear for using that setup? And should I go 3S, or settle for 2S?

I should mention that i have 2 race-tracks around here where i'm gonna learn to drive it, onroad and a loose-dirt offroad track.

Thanks

i would usually recommend 3s lipo for any rustler but because you are using it to race use 2s to keep it controllable

that steel spur would be find as long as you only use it for speed runs because you tend to break alot more parts inside the transmission with that
