Most guys in 12th scale do in order to reduce the pod from binding with the higher gauge wire. I'm not sure about any other class.

With a mod motor and 6 cells I probably would not run less then 14ga. The amp draw is what kills small gauge wire.

Anyone ever pop open an esc and see how thin the pc board leads are?? Having 12ga. wire soldered on to a pc lead that is maybe 4 hairs wide seems strange. I think 14ga. is sufficient, but still overkill. I've used 16ga. for competitive stock racing and didn't have one problem. Something to consider.--Al

Yes - I am using 16 AWG for my 1/12 with 19 turn motors ... however, if you are going to run a hotter mod, I would recommend at least moving to 14 AWG. To test what gauge to run, you have to calculate expected max amp current running through the wires. Motors running off 4-cells draw much less amps then with 6 cells - however, when you move into low-turn motors, their amp draw tends to exceed the capacity of smaller guage wires and actually cause them to melt. 16 guage wire is rated for 22 or less amps, where-as 16 guage wire is rated up to 32 amps. If you know the expect max amp draw of your motor, you can select easily - if not, play it safe and run the larger wire.

Although the size of the wires within the ESC are smaller, they also travel a much smaller distance which allows for these low diameter wires to be sufficient - especially since these wires are probably only handling small amp duties. The board is handling the larger amp duties - hense the lack of larger wires in the ESC.

I thought its the other way around. when you increase voltage it lowers the current draw? Maybe you meant total amount of power?

Nope... what I meant was that as voltage delivered to the motor decreases (via battery voltage output) - so does amperage from said motor thus allowing for a smaller diameter wire (i.e. 16 AWG) since there is less draw through the wires via the speed control.

I run 18 awg for 1/12th Stock and 19T. I have heard of pro drivers running 18 awg as well for Mod. (I could be wrong)
Novak makes some really nice 18 awg if you can find it.
