Neu 1515/2.5D or 1512/1.5Y, 2.5D... which motor?

Oh, I also pulled the Quark out of my truggy today. Since I have to run the Feigao anyway, I decided to stick with the MM. It runs cooler and I'm not as worried about blowing it up. Besides that, I went out to the track again and I'll be darned if the MM wasn't better for me on the track. It was just less abrupt coming out of the turns. I suppose that I'll just have to play around with the Quark settings a bit more.
