Newbie needs help with brushless e revo setup

Go Here and use the speed calculator: http://www.scriptasylum.com/rc_speed/index.html

You can evaluate a motor based on the number of rpm's it will turn with a certain voltage. You will see that with a 1515 1y compared to a 1515 2.5D on 4S, you will get much better rpms out of the 1y. Why? I cant really tell you - one of our resident experts can weigh in on that. You can also compare other motors as well on there. All I know for sure is that you want to stay in the upper 30K to mid 40K rpms.
Like others have said, the 1512 can work in a Revo, but unless you've got it at the minimum weight, you're better off getting a 1515 series. It will be much more efficient.
