I would get a tekno Neu 1515 2.5d (
http://www.impaktrc.com/product_info...oducts_id=3582) if you are racing.. if you just bash maybe the Tekno Neu 1515 1y (
http://www.impaktrc.com/product_info...oducts_id=2620) or go with a
70mm Medusa v2 motor (1600kv) if you are on a budget.. (2000kv rated for bashing) it's not as good as the Neu, but it's still a great motor also maybe the 80mm if you are not racing and want more power.
