The 5700 cc motor is a short can size, or about 50mm long, and it is a 2 pole design motor. The neu 1515 1y is longer, and has a 4 pole design, both of those features allow it to make more torque. It does have lower kv rating, but most run it on 4-5lipo. A 5700 motor is only good for 2-3s lipo and does not have enough torue to move a heavier vehicle, that is why it is strictly for 10th scale.

A higher kv just means that it will spin faster with the same voltage. The kv rating does not refer to the power output, toque output or motor size.
