Got a Modded new style Emaxx coming in need advise on gearing and batteries

[Cain]

Hey all,

I got a newer style Emaxx coming in that is pretty loaded. Anyway, I have to use 4S max per RC Pro Series rules, and need to be able to make 25 minutes for a main, preferrably 30 if possible.

I have heard that a MT doesn't put as much load on an ESC like a 1/8 scale buggy, so figure maybe this means you don't need as insane batteries.

Anyway, here are my questions:

1. I am looking to do a 2000 or 2200Kv motor, what pinion gears should I go with to get race level speeds (say 40mph and lower like my 1/8 scale buggy) on 4S?

2. What are the max battery dimensions that can fit in the emaxx? (height needed too just in case in the future do 3S packs)

3. Are the pinion types for the Emaxx 32 pitch (confirming here)

4. Are there mod1 spur gears for the Emaxx that you can use and if so, what pinion range is needed for them as well as what you have to do to mount them up?

Most likely I will use my current Mamba Max ESC that is modded for this setup on 4S that was in my 1/8 scale already.

Thanks!
