So got my son a Granite BLX, fun little truck when it works. The ESC seems to overheat pretty fast. Running 3s packs (esc rated for 3s) and it goes into thermal protection at 180 degrees. I have no fan, and seen Castle has a fan for this esc but the RPMs are 10k. Was wondering if anyone has rigged a WTF or YeahRacing fan on the esc, or has any idea what we might can do? Looking for recommendations...Go! edit...when I say fast, I mean we cant even run a pack through it. I'm talking within 5 minutes it heated.
