OK, so it seems something is definitely wrong with ThunderbirdJunkie's SC10 4 wheeler.

Battery just took 38xx mah, charging after last night's main. That being said, there was about 5 minutes of screwing around afterwards, but 12 minutes to put that back in a 5000mah battery, while when the truck was fairly new it ran 23 minutes and was cool as a cucumber.

It came off the track with the 1410 at 160 (acceptable, but not ideal considering the 15/62 gearing) and the speedo (Mamba Max) was a smoldering 209 after the first 5 minute heat. Since it got cooler as the night went on, it wasn't so bad later, but the speedo was still in the 180s and the motor in the mid 150s.

Belt's loose, when there's no pinion on it the truck rolls nice and smooth...ThunderbirdJunkie is ripping his hair out trying to figure this out.
