Well the one I preordered from CC arrived today. I figured that the first ting people would ask is to see what inside. Couldn't read any of the fets as the heatsink was covering all of them, but I snapped a couple pics just to satisfy the curiosity.
Big sucker... Weighs in just shy of 1/4 pound.
Looks just like the one they displayed at iHobby back in October
Back side of the board. Looks like the brans and BEC to me, but I'm not electronics expert.
Inside the case. You can see the fan is replaceable. Takes a total disassembly of the esc to get to it though. Looks like a standard 25mm computer fan. The fan wire plugs into the bottom of the board at the little white box next to where the Rx wires are soldered on.
