Making an esc better?

[GriffinRU]

Wow, back to sensored systems, ... long time no interest and finally.
I'm slowly (for one of my projects) making a power board for HV-Maxx, but was not expecting any interest in that combo here. Feigao has full line of sensored motors and Aveox as well. Well, I had a thread here on HV-Maxx and Feigao combo...

Mamba first, Quark second which brains we want to add?

To zeropointbug:
How much power you think you dumping on ESC?
What kind of Amp ratings you would like to have from ESC and why?
