I believe his site is under reconstruction so it is probably easiest just to PM here at RC Tech.

Cool, does he have bearings also?

Yes, but ceramics only :cool:

question...

i have some decent wire i got from another place, but its 18ga. says its "high-strand count copper wire"... would that be big enough to use to the motor running the 3.7 lipo/13.5 combo? or would i be better off running something else?

18g is too thin....go with the OD Racing wire, It's the best :nod:

I beg to differ that it "depends". I've tried the smaller wires. Anybody know the gauge of the wire that brush shunts are made of? Didn't slow down brushed motors any... ;)

and doesn't electricity travel on the outside of wires? So low count 16 or high strand count 18. hmmm. I might be all wet on that "how electricity flows" thing. I haven't actually cared to look or remember for many years. I go with what looks the coolest. sad ain't it. ;)

<---just being argumentative, but it does "depend". It's not a permanent installation, it's six hits with the soldering iron and 12" of wire. Try it! :)

Try it wtih both wires.

I don't know how true it is, but Big Jim Greenemeyer always used to say that the shunts were good for ten amps or so, and that the majority of the current going into the motor was carried through the brush hoods right into the surface of the brush. I know I once raced a car for a whole race day with a broken shunt and didn't notice until I took the motor out to cut it before the main... I was suprised it ran at all without that shunt...

It's known as the "skin effect" and if I remember right it was said to apply more to high frequency alternating current... I suppose the high switching rates of modern ESC's would make it apply to us, but I don't know for certain.

Not sad at all... I'm not as fast as was fifteen years ago, but my cars look cooler... and if you can't go fast... LOOK fast!

Knowing you Wes, I can guarantee you won't feel the difference between 16 and 18 gauge of the same quality, much less high quality 18 gauge vs average 16 gauge. Along the lines of Bob's post, the solder joints we create at the PCB on the esc and the motor tabs on our current BL motors create much higher resistance than 18 gauge wire IMHO. :)

Like this? :)

You are correct that the current flows on the surface. More strands is better because there's more surface area. But the trade off with a high strand 18 gauge is that the voltage drop is greater with the 18.

Well all my goodies have finally arrived and I'm in process of building my DB12RR conversion kit :) Thanks to OD for the great 16awg wire I got from him :) I also wanted to mention something I haven't seen posted here yet that I picked up. CRC has a new flexy sensor harness wire...Man this is a very flexy sensor wire...it's a noodle! Definitely worth taking a look at for 1/12th racers if you haven't already.

Wondering if it's the same as the TQ sensor wire , just got some from Stormer and same thing it's like a noodle.

EXACTLY like that... Sah-WEET!!

Thanks for the shock and wire clarification gentlemen, that's a great help!

Might be...didn't know TQ had one too now...cool
