Well, I'm pretty sure I didn't reverse polarize it, as the only way to do that would be to have incorrectly soldered my Deans on, but I would have known about that before now. I'm not sure if it is the cap or not, but one of the caps seems to have oozed an epoxy like substance out the side that has cooled and bonded with the shrink wrap, making it very difficult to remove. Also, that cap's metal top is kind of bulging out, but the others are not.

Could it have done that by being plugged into a fried rx, because the one the ESC was plugged into didn't seem to be working before all the smoke came out.
