Only thing I would add to this is that while you can run a single ESC, just beware of the turn limits an ESC might have. Some are designed specifically for stock/spec racing, so to minimize resistance and optimize the design for its intended purpose, you might find that some ESC’s have like a 10.5 turn limit... others I’ve seen can handle as much as a 5.5... So just be sure that you do your research and find an ESC that will be able to handle what you plan to run. I really haven’t heard of anyone using anything hotter than a 6+ turn motor in 4WD so far from what I’ve seen online. IIRC, Dakotah Phend has been running a Trinity 7.5, for example.
