Here is a picture of the buggy. The Quark is mounted upside down and also I threw in a picture of the open ends of the Neu motor, which I later taped up.

Sounds like you may have got something there, I'm just wondering how much of the heat drop can be due to the neu motor. That and the ambient outside temperature make a big difference. I just noticed mine is loose and am going to do some changes. The shrink wrap on my caps looks like it got hot and came off, they read 35v 330uf . Im also wondering if the fact that only one bank of the fets is connected to a heatsink that sees airflow has anything to do with the overheating.
