Got it, makes sense.

So I want to build something on the larger side, I'm thinking lightweight ~60lb class. That way I have power and mass to use it for other experiments than battles. I'm trying to get a feel for what size motors, batteries, and ESCs are needed for something of that size. Are drill motors or wheelchair motors better suited for this size? Some of the drill motors have massive stall currents, but what size ESC is suitable for regular operation?

I'm very familiar with electric power systems, but usually in aircraft, so I'm not sure where to start sizing things on the ground. Once I have a baseline example of a working setup I should be able to feel it all out myself from there.
