some one jump in if i'm wrong. a lower turn motor (number) will increase wheel speed, and loose torque

If your starting out a 55 turn motor and a Novak Rooster crawler will work great. What kind of rig is it going in?

Default motor turn

it's true the lower the turns on a motor the higher the rpm, which inturn results in higher wheel speed and lower torque:-(. if a motor is designed for crawling within a set turn, dont try to go too far outside that area, you'll be waisting your money. good luck

so far :
x4 moab g8 tires
x2 proline beadlock rims ( front )
airtronic 3ch rec.
punk rc dig
hitec servo
2 strips wieghts in each front and 3.5 in rear

A higher number of turns of wire around each armiture of the motor makes a stronger magnetic field when it is energized. To get this high number of turns you also have to use smaller wire to get that number of revolutions around the armiture. The smaller wire therfore cannot flow the amount of current as a lower turn motor with larger wire which makes it easier on your speed control. You need to find a good balance between wheel speed and torque without generating too much heat.

the turns on a motor determine how the motor performs( 8t, 10t, .....27t...45t the list goes on and on. there are tricks with it to, timing, type of winds(flat or round) single, double, triple, all change a motors characteristics. a high wind motor ie over (27 turns, and i am using a 27t as a base as it has been the most common "stock" motor by application for anything 10th scale as far as i can remember) typically turns less rpm the more winds you have but has much greater torque, and less overall amp draw. a low wind motor like a 10t has a much higher amp draw and turns aaalot higher rpm and has more horse power, now timing advance also changes a motor also, timing advance is measured by the center of the brushes to the magnets, now as far as your speed controller is concerned, it should have a motor limit, (most but not all do) listed in the instructions, as dont go under a certain amount of turns because too many amps will be drawn by the motor and can cause it to over heat. this can happen in milliseconds, speed controllers generally for crawling are designed so that at lower throttle (less in put from your trigger finger) you have a greater range of control, but instead of buying motors and batteries i would invest in some gears first try simply putting on a larger pinion and a smaller spur, you will probably find out you get a better out come with that than changing other more expensive parts first. and there are pros and cons to EVERY change you make. and if anything i said is incorrect anyone please correct me. and by the way its all about having fun, so keep on truckin!

an esc does NOT make power it only controls it its kinda like a dimmer switch for a light, if you have a light bulb and a 9v battery and you connect the light to the battery that is direct power the light will be as bright as it can get, "full throttle" so if you take and put a dimmer switch in between the two you will never get any brighter because the switch does not make power, as a matter of fact it is resistance so the light will be a little dimmer just not enough to even notice. however you will be able to control how dark the light can get, that is what an esc does, it is the dimmer switch, esc's in general have such a low amount of loss now that at full throttle their is almost no loss, crawler esc's are better at controlling low throttle inputs(the light is really dark), and set that way for better control at low throttle setting. in my opinion novak puts out a very good product, but as far as what will work best it is up to YOUR driving style, it is said on here all over the place give twenty sets of axles and twenty frames you will see twenty different trucks, and each truck made for that drivers style, the one thing nice i have found about a crawler you really cant do anything just wrong, its all about what works for you. i run a 55t motor in both of my trucks and also little bitty 7.4v 800mAh lipos they last about 4hrs in my truck because i have such a high turn motor, remember a high turn motor does not draw a lot of amps. so large batteries are not really needed P.S. they are also very light so they help keep my center of gravity very low. my trucks are also scalers so space for me is limited, but i also have many other types of cars, and everything goes by application
