Flat, please send a pic. So here's the thing. A device, like a motor, will only draw a certain amount of amperage at any given voltage. Here's a simply analogy. You've got a 100 watt light bulb and you plug it into a socket that delivers 15 amps of current (a typical home wall outlet here in the States). The bulb wants to draw 1 amp of current. There are actually 20 amps of current going to the socket, but the bulb only wants to take 1 amp to shine brightly. So the cord to the lamp is pretty thin. It might only be 18 gauge lamp cord.

Now let's say you plug in a vacuum cleaner that uses 13 amps because it has a big motor. To deliver all 13 amps of current, you need a 14 gauge wire. Still, it's pretty thin. The cord on the vacuum cleaner is just a little bigger than speaker wire.

But now let's say you have an air compressor that needs 20 amps of power. Now you're going to need a 12 gauge wire to deliver all that current. It's a big stiff wire with a lot of surface area (the circumference of the wire) to carry the extra power.

You can see where I'm going here. The bigger the device, the fatter the wire needs to be to carry the current.

But these Li-Pos are only a few volts. Granted, the amperage is high, but your motor is only going to draw what is wants, just like the light bulb I mentioned before. So the wires don't have to be that big.

As I said before, regular thin gauge speaker wire should handle anything that a Li-Po battery can deliver. Just look at the gauge of the wires coming off the battery. Yes, it's bigger than the hair-like wires that Hasbro uses. But it's not the industrial cable that some modders are convinced is needed to power their motors.
