what gauge wire does the '07 Sphere TC Specs come equipped with? (i believed it was 12AWG) Am I wrong?

Does LRP now equip the newer ESC's (SPX, SXX) with thinner 13AWG?
The SPX Comp comes with 13AWG.

If you could tell the difference in performance, you wouldn't need to ask this question. Go for coolest color.

Resistance of the wire has to do with the number of strands in the wire. Higher strand count has two benefits. It can carry more current and is more flexible. If the wire you are using is stiff it is ineffiecient regardless of the gauge. Keyence sells some of the best wire on the market. There 14ga wire has less resistance then most 12 gauge wire out there due to an extremely high strand count. If you are worried about current capacity, floppy is best.

Hmm...interesting you say that.
Sphere TC comes with 12AWG and the SPX with 13AWG?
Wonder why the drawback...12AWG not necessary...or to save a few bucks from the manufacturing?

Anyone have an SXX esc they could check for wire gauge?

personally, that is my last decision when I purchase just about anything.

"TQ 13 Gauge wire is constructed with 1,296 strands of bare copper and thin wall silicone. This wire is only 3.5 mm ODÖas thin as most 14 gauge wire and delivers more power! The compact 13 gauge conductor fits easily into ESCís and BL solder terminals. Itís thin and super flexible to make quick work out of neatly wiring any car. "

How does Keyence stack up to TQ?

I love wet noodle. :P Used that stuff for a long time.

My sxx tc came with 12ga. Says, "Silicine flex-wire" on it. Now I compared this to the Deans 12ga wet noodle I have. The instulation on the stock LRP wire is thinner then the Deans makeing it appear to be smaller gauge. Now I cut the instulation off and they bother measured up the same.

Default nexus racing

update guys:

received a response from a CSR over at Nexus Racing and that person says that the TQ 13AWG super flex wire will not decrease the performance of my setup in comparison to the traditional 12AWG...just an FYI

I am running some Kyenece 14ga that is 1015 strands. Like I said high strand count flexible stuff is what you want. TQ stuff sounds awesome.

Awe yes, sales people. Anything to make a sale.

Heres the thing, it will make a difference. Period. The thing is the difference will be so small that you should not notice it unless you are running some crazy Mod motor in your car. When a low turn mod motor is drawing massive amp loads the wiring can make a HUGE difference, for most of us, not so much.

Buy some nice wire that you like to work with, and you will be more then happy.

That's the key. You need to be able to solder it well, as it can be efficient as you want in the packet, but if you are relying on a glob of dirty, crappy solder to hold it in place, you've lost any gain in the wire itself.

I have used many sorts of wire recently and have not noticed any performance difference running 17.5 stock class,

wet noodle
keyence 12ga
keyence 14ga
TQ 13ga

that being said the TQ 13ga is the easiest to work with imo.

In stock I would not think you would notice any difference at all. Guys. IF the wire is not getting hot there is not a significant power loss and I doubt you would notice anything in feel or on the clock.

That is a good point. If you notice the wire getting hot or warm, maybe you should use a lower gauge wire.

My godson reminds me to question information posted on Wikipedia, since you don't know the source of the edits. He has a good teacher ...

Reading this thread reminds me of the Skin Effect. A google search turns up a good discussion of Litz wire:

http://en.wikipedia.org/wiki/Litz_wire

where the ESC involves fairly high switching frequencies and the better wires are probably built on the model of Litz wire.

This paper describes the distinction between un-insulated stranded wire and more expensive Litz wire:

engineering.dartmouth.edu/inductor/papers/strandedopt.pdf

where ordinary stranded wire provides some of the benefits attributed to Litz wire.


Silicon insulation is key to higher current and heat ratings too. One can read specifications of an industrial cable supplier to infer which features in the wire and insulation make a difference in the ratings.

However I agree the difference on the track or stopwatch is nil for any good brand or small change in the gauge of wire.
