best brushless combo slash platinum

What is the best motor esc combo for a 4x4 slash if I want to at least run 3s without it getting hot?what system a what kv motor?

I'm running the mmp sct 2400kv in mine and on 3s and 4s.

Define hot.

I run an Orion Vortex 2,000 KV with a Hobbywing SC8WP ESC in my Prolite. On 3S, it runs 130*-145* with no cool downs allowed. The stock motor was a 3,500 KV 550 can with a 14T pinion to the 47T spur; with the 1/8 motor, a 20T pinion was the minimum to gain clearance for the can, which puts the calculated wheel RPM per volt a little lower. But that 550 motor was getting up into the 170*, 180* range if I ran it non-stop, where the 1/8 electronics don't have to work nearly as hard.

I haven't radar checked it yet, but I estimate top speed on 3S to be 40-45 MPH. It's a 4S capable system, but I have not run 4S as of yet. I'm bettin' it'll really start breaking parts if I do that.

Truck gained about 6 ounces, but still handles well.

In short, if you want to run your truck hard on 3S and not worry about cooking things, I'd shoehorn 1/8 electronics into it.

I would like to do 1/8 but i would have to buy more stuff. What does everyone think of the sv3 castle3800kv or 4600 kv. What one is better for slash 4x4?

You're buying a new combo anyway, what else would you need? Most 1/8 motors have tapped holes that align with 540/550 mounts.

My Prolite required only some clearancing of plastic and the larger pinion gear to install the larger motor & ESC; it bolted right up to the stock mount.

I think any 540 motor in a 4WD SCT on 3S is going to result in short life of the motor and/or ESC.

This. I burned my 3500 vxl up by running 3s.
