I had phone conversation with Mike and we are not sure what happen to ESC, besides smoke and short. We do know the place where short happen, maybe related to pcb motion (I used different method for keeping pcb's from moving inside, when I built Jeff's ESC) inside. Aluminum cover was well insulated inside from shorts to power fet's boards, but apparently I missed something on brains side.
I will give you updates on Friday, but one thing for sure it is not related to overload or thermal and I am pretty sure Fet's are good.
Newer enclosure would have better layout and there is no reason to use heatsink grease on the bottom, I can use silver epoxy to fix pcb's from motion inside the box.

In future we are going to have much better cases (top and bottom) anodized and pcb's are permanetly attached to case with mounting tabs.

Jeff, Thank for you time and feedback.
