You know what, I can't even say for certain if I think the 1512 or 1515 is better for a buggy. I really haven't done the right kind of testing back-to-back with both motors. And I don't know anyone else that even has both motors in a similar kv like I do. When racing season is here I hope to learn soem more about them. I have the 1512 in a buggy and a 1515 in a truggy... with 12000mah packs.

I don't know which motor would run cooler in a long race, or which one would help keep the esc cooler. I believe if you use the help of a fan, it doesn't matter. Both my vehicles seem to be good enough in performance and temps.

I did start using fans most of the time in my cars so take that into consideration. I ran the truggy for +30minutes nonstop and checked the temps several times during the and both motor and esc ran in the ballpark of 160*, not bad imo. Without the fans I would guess temps would jump to like 180* but that's acceptable for a long run w/o fans, imo.

I have run BL systems much hotter than that before.... my Emaxx/Hacker used to run 180-190 motor and 200 esc... and my SS5800 XX4 esc ran 200-220 at the end of a hard race.
