Extend ESC wires with 18 gauge wire??

I have extended the three wires on an ESC with 18 gauge wire. As far as I can tell, the ESC is 16 gauge wire. I have had no problems with this set up, but I'm getting ready to do the same thing to two others so thought I'd check in with you guys and see if you had any thoughts on this.

Is this a bad idea or no big deal?

Thanks!

Probably as long as you are not putting 40A+ through those wires you'll be okay.

Extending the battery or motor side wires?
Pardon me.....I see you said 3 wires, oh well.
Most knowledgeable people say to extend the motor wires and not the battery side wiring.

I have been using single-strand wire for 4 years, on 10 models, with no problems.

I use the same method for long servo extensions.

Peterangus, I see your wires are all black. How do you know which is the ground, or does it not matter? I notice my new ESC wires are all black.

Thanks!

Connect up, any to any.

If the motor runs the wrong way, swap any two of the three motor wires, anywhere in the cicuit.

There is no ground. All three motorwires are equivalent, have the same function. They are not the same of course.

Any two of the three motor wires. NEVER EVER swap battery wires to reverse rotation, will cost you a controller (brushed, brushless, all electronics in general).
