Quark fried, blown capacitor...

Well, I had it all setup. I had done a test run and all was ok. I got the esc mounted in the new case, plugged it in and...nothing. What the heck. I unplugged everything and checked everything and noticed that the top pcb had pulled out of a socket of some sort on the bottom pcb. I pushed it back in and hooked everything back up and...SMOKE.

Oh well. Back to the MM and nice cool running.

I thought that the two pcbs were supposed to be soldered together. Why would they separate like that. Maybe the guy that soldered the motor leads on did the pcbs too.
