Judging by the results others have had, the 1512 2d is a great motor on 4s lipo- easily more power than a hvmaxx system, and geared correctly runs plenty cool, even in the erevo which is heavier than either new or old emaxx. That said, if your friend starts a game of one-up manship, you may quickly find yourself wanting the larger 1515 motor...
