Hey Guys

Anyone know of a good place to get a good explanation of what motor I need for on-road?

Reedy and Trinity web sites don't help much as I want to understand turns and winds, big or small comms and all that stuff. What are the advantages of lower turns? Why do some people say they wouldn't go below 16T? It's all a little bit giberish at the moment.

Any help would be great :rolleyes:

A turn refers to the number of times the wire is wrapped around the comm (I think).

The advantages of a lower turn is that it will have a higher rpm. The disadvantages are that it will drain batteries quicker and the motor will have to be rebuild more often because the brushes will wear out faster.

Some people say they won't go below 16T because anything below that will be too much power for the track they are running on (this is more particular to off-road racers).

I hope this helps.

I have been told that pan car oval guys stick with motors with 20 or more turns. I run stock motors in mine and still can spin the rears at will. I also run stock, 27 Turn, motors in my on road pan car with the same results.
RcBum is correct about the number of turns thing. Unless you have got a ton of room or aren't making a lot of turns anything below a 16T motor would be very hard to control. I don't know what kind of on road car you are running but too much power can be a bad thing, did I just say that? :eek:

When a motor is listed as being a 16X3, it means the it has 3 strands of wire wrapped around the stacks (on the armature) 16 times. The lesser turns means more RPM, but more winds (strands of wire) it has, the less amount of torque it has. eg. a 16x1 will have more torque than a 16x3, but both with very similar RPM. BUT, the more TURNS a motor has, the more torque it has but not as much RPM.

Pan car drivers would probably be using 20+ turn motors because they have soo much torque and those cars go like **** with any motor.

I use an 11-turn in my 4-cell 1/12 scale.
At big races and big tracks 1/10-1/12 cars have anywhere from 8 to 14 turn motors in them. Same for TC's. Lower turn means more rpm and power. Low (6-9) turn motors are harder to maintain, they need new brushes and a comm cut often. They also demand good batteries in order to get enough run time. You can get most of the speed and power availiable in mod racing in the 10-14 turn budget mod range.
