lol, now I have to scrape the old heat epoxy gunk off and put the heatsink back on. :)

Before I do this, is there anything else that anyone wants to see?

I thought the BEC would be in the middle layer, but that looks like the USB controller chip. Note the insulating white-ish material between the IC and the FET layer to keep the heat off the controller. I really think the BEC is made up of those two chips on the upper left corner of the first image above. I looked up the part number, and they are simply transistors. And looking at the traces, they are paralleled (bad idea for transistors IMO). I'll have to hook up the ESC and measure them to be sure. If those do make up the BEC, I might see if I can either heatsink them or remove them and squeeze in the ParkBEC I have. :)
