Nice progress!
Are you still going for 8s? I´m wondering since the esc you linked is limited to 4s...
I assume that it´s from this family of escs:

I have had several of them in my revo conversions, they are great. One Important thing tho, they do have a "car version" of it..:

But I could never get the breaks to work properly, no mather what setting I used they would lockup.
If you are going for 8s I suggest this one with mecanical breakes:
