Question about a Neu motor

[Gee]

I started out with the 1515 1y in the eight on 4s and it was sweet. I came across the 1512 1.5 on here and it was a little less weight and I read a lot of the other buggies were using the 1512's too. I don't race but I do like to haul ass. This thing is impressive with the 12 on 4s. Handles great at the higher speeds. I run a 16t on it and just won some dace 17mm adapeter for $5 of ebay. They added a 1/2 in to it. Fun!
