I race my Slash on a loose dirt oval and am having heat issues with my motor. On a 4 minute run I get my motor gets near 200 and that is in cool weather. I currently run 100 k in the front 200 k in the center and 10 k in the rear. My gearin is 11 pinion and 51 spur both steel gears and oversized bearing. The truck handles and pulls great the way it is setup but I need to fix my heat problem. Any suggestions with reasoning so I can learn would be greatly appreciated. I left out I use a 3s lipo.
