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

haha Jeff we need to meet up some day to figure this one out..

the 1512 was too hot in my LSP, and also heated up my quark quite a bit as well. I'm now running the 1515, and geared it up to match speed, and I can barely feel any warmth from the 1515 or the quark.. are you talking about your truggy or matrix? my experience was 5s as well.
