If you know the resistance of one motor, you can calculate the restistance of all other winds. Say you have a neu 1512 1.5D which has 3300kv and 0.003 ohms and you want to find the resistance of a 1512 2.5D. To find the resistance, you just take the ratio of their winds 2.5/1.5 = 1.67, square it = 2.78, and multiply by resistance of the known motor and you get about 0.008 ohms. Since higher turn motors are wound more consistantly than low turn motors, expect higher turn motors to have slightly less resistance that what you would calculate and low turn motors to have slightly more resistance than what you would calculate. Now you can compare what wind feigao motor will be equivalent to your neu motor or vise versa, since two motors with the same resistance are considered equivalent powerwise, even if they have different kvs. And of course you get more power by going up in cell count with the same motor.
