I'm thinking of doing this to a car, but if there's no advantage to the splice I will leave that step out and run 18 gauge all the way from the esc to the motor.
Actually, the important wires for power delivery are from the battery + terminal to the motor + terminal, and from the motor - terminal to the esc - terminal. When you splice a wire onto the batt+ to motor + wore to go to the speedo +, it can be ANY piece of wire. I've even used 22 ga. servo lead there. The wire from the batt + to the esc+ powers the ESC only, it does not deliver any power to the motor.
I see a LOT of guys run the + lead from the ESC to the motor, then splice a piece of wire to that to go to the batt + terminal. This is backwards... they're putting another solder joint in the power path.
The way ALL brushed ESC's work is on the negative side, power to the motor should ba a straight path from batt+ to the motor +.
Hope that makes sense...
