Hobby King 10 guage with lots of fine threads of wire
or home hardware 10 guage with a few course threads of wire
HK is nice, has a good feel to the insulation, the strands are fine so you can wipe them up easily, a few strands fall into the carpet and no big deal. The wires hang nicely off the battery and controller and dont get in the way, usually.
Course thread strands I pick up, each and every one. It is stiffer and doesnt have a nice feel. Easier to solder I find then finer thread wire. Easier to dump into a bowl of solder then fine, for an XT. The wires will stick out and get in the way if you dont bend them out of the way. Price wise, much cheaper then HK, because hk you have to wait. Now an interesting note is I have yet to find a fine threaded wire at any electrical supply, the rc stores would have them.
Bought some 10awg wire at H.D. today on the returns rack for 50% off, got 4m for $2cdn, its single conductor and course threads but that got me thinking about H.K. Turnigy wire how there are so many fine threads. It did not take me long to find the answer, sure its more then likely posted somewhere here on E.S. Search term "fine wire course" has 310 matches and 12 pages, hey nothing stuck out so searched on.
Makes sense

Ahhh trick question. This question touches on both practical as well as theory.
First let's discuss theory... Electricity travels along the very outer edges of an conductor, this is known as the skin effect. No matter how thick the conductor is, the electrons are only traveling on the outside edge, so the more outside edges ( smaller threads) the more surface for the electrons to travel on. So one could draw the conclusion that many threads will be better.
Now for the Practical ... The more amps required the larger the size of the conductor required to carry it.
So the question becomes which is better, a solid wire or a stranded wire? With all things being equal, the size, the insulation, the ambient temp, there is no difference between stranded and solid conductors. The only real difference is that stranded conductors are much more easier to install in conduit, and even more so when factoring in bends .
The technical answers have already been given, the heuristic answer would be as follow (IMHO):
- Finer Threads for low voltage/amperage usage. Where the wire essentially experiences no heat due to over-loading (think Speaker wires or something similar).
- Thicker Threads for low-medium voltage, but higher amperage usage. Where the wire can experience higher heat due to over-loading.
The finer threads will burn out very quickly if they were used for a circuit that would carry a higher-amperage.
.There is no resistive difference between equivalent gauge solid and stranded wire. At 60Hz, the "skin effect" is negligible. The only difference is that stranded wire is easier to pull around bends, and there are a lot more bends in office wiring.
