Default Wiring up an ESC

I just acquired a used Cyclone C2 ESC and I'm wondering about wiring it up. I have the factory instructions. It looks like only the negative side of the battery is actually being regulated through the esc.

Can I run a heavy positive wire from the motor directly to the battery and a lighter wire to the positive pole of the ESC?

I'm not an electrical engineer but logically if you made half the circuit a smaller diameter wire wouldnt that restrict the entire circuit down the current capacity of the smallest diameter wire?

Doesn't look to me like the red wire on the ESC would pass any current other than to power the ESC and the BEC. All the current from the positive pole of the battery to the positive pole of the motor passes direct.

So if I run a heavy wire from the two positives (motor and battery to each other) and heavy wire from the negative leads of the ESC to battery neg and motor negative, the red wire on the esc only needs to be of a smaller diameter. It doesn't power the motor.

I'm just trying to work with the way the esc is currently wired. Two heavy black and green leads, and one lighter red.

Yes, you can use a smaller guage of wire to "T" off the main lead down to the esc.
