I don't think you can go wrong with any of the brushless systems out there. The technology has matured to the point that all the major brands (and even some of the generic brands like hobbywing) are pretty competent at giving you a good stuff...

The only thing to consider is either sensored or sensorless. If you want to run a higher turn motors (such as 13 turn and beyond), you should go with sensored since sensorless motors tend to struggle with higher turns...

But it's all preference. I hear that sensored are butter smooth, but I'm not skilled enough to be able to tell...

I use sensorless system in my two vehicles. Both of the ESCs are Castle Creations Mamba Max with a 5700kV motor and 4600kV motor. Why do I have two of them? Well I bought the first Mamba Max with the 5700kV and was so satisfied with the performance, I bought a second one for my second vehicle...

If this is a first brushless, I would start out with the 4600kV... I started with the 5700kV and ended up breaking TONS of parts. Besides that, I still toned down the timing in the ESC with the 5700kV to "Lowest" to reduce the RPM on it...

It feels good now, but the 5700kV is WAAAY too much motor IMO... If you're a basher and want some pure speed and tire smoking, get the 5700kV or the 6600kV version.

The 5700 with a 6-cell runs about 8,000 more rpms than the 4600, looks like I'll be getting that, plus RC Madness carries them and basically with how much stuff we have bought from them, if something breaks while racing there, Chris replaces it for almost no cost if it was a defect or some freak accident.

Did you ever think about looking at Tekin?
They have sensored and sensorless ESC.

i have a friend that was running a tekin 4800 and it looked good on a 3800 lipo. I saw one with a 7700 mamba and it was way to fast. You couldnt even mash the gas without the front end comming up and over the rear and flipping. The 7700 is way to much power for the slash. Its fast as balls but to much motor. Im going with the 5700 mamba max. and i think that will be plenty for me
