motor turns
What does the number of turns in the various motors mean? What is the significance between 12 turn and 21 turns?

Number of Turns
Refers to how many times the copper wire is wound around each pole of the armature. Basic guide:
More Turns (e.g. 19T) = Higher torque, less rpm, longer battery life. Slower but easier to drive.
Less Turns (e.g. 12T) = Less torque, more rpm, shorter battery life. Faster but more difficult to drive.
Number of Winds
Besides the number of turns, the number of winds refer to the number of wires wound around the armature. Basic guide:
Single Wind = Most bottom end power. Power is achieved at lower rpms. For short racing tracks with a lot of turns.
Double / Triple / Quad = Less bottom end power. Power is achieved at higher rpms. For long racing tracks with long straights.
Turns
Turns refers to the number of times the copper wire has actually been revolved around the armature. The higher the number of turns greater is the torque generated and hence greater is the power delivered. However that also means less RPM rating for your rc car electric motor. Generally less turns are preferred for making the rc car run faster.
Winds
One or more copper wires are usually wound around the armature. The number of wires that are wound around the armature is called the wind of the motor. Sometimes the wind is increased in order to compensate for the torque lost by reducing the turns.

And:
Stock motor is always 27-turn single-wind armature with the endbell keyed to 24° of timing (relation of the brushes in the endbell to the magnets in the can). And if you want to play in ROAR's sandbox, it has to run bushings
Super stock is a 19-turn single with (I think) adjustable timing (although most people just refer to them as a "nineteen-turn motor"). You can also run ballbearings in a 19T
Modified is go nuts

what motor to run
Thank alot for the info guys. So basically it is up to me what type motor to run based what type of track or application I am running the car in.
I assume ROAR has rules on this so no one individual has an advantage.
But can anyone ESC and Battery Pack handle any motor?
Thanks

No not all esc's can handle any motor or battery. All esc's have a motor rating and voltage rating. Some esc's have an unlimited motor limit though.
If an esc has a motor limit you must run a motor at or above the limit.... If its motor limit is say 12 turns you must run a 12 turn or higher, 19t, 27t etc.

rule book
you can download the rule book here. http://www.roarracing.com/rules.php If you're racing it's nice to have a copy for a quick reference.

Loopedout, OTE--Thanks for posting that info! Was kind of curious about that myself re:winds/turns.

This is a great thread with lots of information. Can someone also explain brushless ratings and if there is a simple way to correlate from brushed to brushless? Thanks.

thanks
I want to thank everyone for their responses. It helps when looking at many different products in the hobby store and when talking to people. It also helps in knowing what to purchase my 7 year son. Nothing to HOT but enough to keep him interested and wanting to win. Thanks

This was just what I was searching for - Thanks..!

Thanks for this thread! Exactly what I was looking for.

You cant blow up a light bulb rated 1amp @ 12V with 10amp 12v DC transformer. But you can blow up a 1amp 12V transformer with a 10amp 12V lightbulb.
