Since I went to using the CC BEC and 4 cell lipo withe the Fiegao motor the heat to the MM is almost non existent

I had the rc-m heatsink on it, Ubec, and no fans.
rc-m heatsink was mounted to tekno mount, the quark to the heatsink with arctic silver paste, and a 2 zipties around the whole thing to holed the heatsink to the mount.
In previous testing runs prior to filming the esc temp never got above 125. I tested in loose dirt, asphault, grass, and sand. After a 30 minute run in sand was the hottest I had seen it was 125, and that was towards the end. I checked temps every 2 mins during the 1st 6 runs, every 5 mins during the second 6. this was the 7th run total and less than 2 mins in, poof. I'm going to call S&T here in a few mins to send it in for repair\replace.
