Wire Size?
 

I have always used 12AWG wire for most of my cars, Is there any chart, or "rule of thumb" that convince me of maybe going to a 14AWG?

I can just put it simply; You don't need 12AWG wire ;)

If the wiring isn't getting warm, it has low enough resistance for purpose.

I can run a 1s 1/12 with a 4.5t and 16AWG wire and the wire wasn't even getting slightly warm.

Ditto.

14 or 16 on all my cars and trucks in 1/12 and 1/10 scale.

12 in my 1/8 buggy on 6S or 5S.

What about when it comes to touring cars n 13.5t boosted, i know a couple guys use 14 gauge

Well think of it like this . motors run on ac current . ac current is 3x more efficient than DC . u run 16g to motors and 12 to battery

When I bought my ESC, it came with 16awg wires which I left on and ran in 13.5 boosted TC's, it was as fast as anything else and the wiring never got warm.
Smaller gauge is also lighter.

Fair enough, my muchmore fleta pro's came with 12 gauge but may swap it out for 16

This was just on my mind and now I stumbled across this post. Thanks for all the input. Currently using 14AWG in my TC and finding it sufficient - so will stick with it!

Unless you run a 2.5t boosted, 14awg is good....

Re:
 

Running 17.5t blinky and using the wiring that came with the ESC; which was 14AWG - working fine.

TQ13 wire works for most 1/10 application

TQ wire is the best whether 13 14 or 16.

Question:
 

I've been looking to purchase some TQ 14AWG - could you please elaborate why it's the best?

Thanks in advance.

Most flexable wire around. I have used this wire both 13 and 16 since the company began.

TQ makes 13 or 16 not 14.

High strand count, flexible silicone jacket. Their sensor cables are the best as well for the same reason.
