and to further add the 1512 will lighten your buggy and it will be easier to control in the air and on jumps....i used to run the 1515 1/y in my 8ight and it had crazy power adn stayed extremely cool but it handled a little wierd...after i got a 1512 it handles a lot better and the 1512 has plenty of power don;t let the small size fool you :) ...
