the Neu motors use larger wire as the wind number goes down/kv goes up. for example, a 1.5D will have larger wire than a 2y. 10 ga is about the largest i have seen and it usually ends up on all winds 1y and faster i believe. i know all my 1.5d rated motors have 10 ga on them. but i have seen the 2.5d and 2y and others with only 12ga, maybe its even 13ga. those 1509 wires are more like 8ga though. the post above this one sounds to be accurate. the motor wires will just come from the copper wire inside the can so the more wire used, the thicker the connection. its a good thing. you want plenty of current in winds that low.
