In this instance, the AWG is all about more strands, and when you peal back the insulation to solder these things, you will see there is more wire. An AWG rating is about the wire, not the insulation. One of the reasons I went to 6.5 mm bullets was to accommodate the thicker wire on the source side of the bigger ESCs and batteries.
But the bottom line here is that resistance is not as important as inductance and capacitance, and inductance and capacitance is not as important as interpreting the timing and avoiding commutation. I have yet to see a ripple value over 3 with any ESC, even when commutation is an issue.
I regret that I never took an ESC/motor/battery/prop setup that developed commutation issues and shortened the source-side wires and added a cap pack in parallel, and retested. By the time I did that, I had already switched out the motor and prop, so I can't say anything about if this works or not. What I can say is that when my systems experienced commutation issues, lowering the prop load fix it 100% of the time.
More load draws more current and power, so just lowering the prop size reduced the power i wanted, and expected. So I now either lowered the Kv and increased the cell count with the same prop, or increased the cell count and went to a smaller prop. Both reduced the current and load, but can match the power-out, if not the torque. Keeping the same prop spinning at the same RPMs on less current requires less Kv and more volts. Sometimes you just need a bigger motor, which is what I'm probably going to have to do to avoid commutation in the MXS.
