I don't know anything about a 1515 but, it is my guess it would not do me any good I am a 1/5 scale guy!
The 1515 is the 2200kv motor from Castle that IMHO changed RC forever. Of course without the dawning of the cheap and hardy lipo none of this would be possible. Perhaps thanks should go to Steve Neu as the design of the Castle motor is built from the Neu motors fully in agreement with Neu. Castle made it cost effective/affordable and they also made it tougher for dusty conditions that our vehicles see. It is the 2028 only 75 inches long and 40 inches wide I believe.

I hope you meant 75 mm and not inches long??? I doubt that these two are the same motors...
