Size of MMM without case?

Um, I would be very careful what you plan to attaching to the ESC. Let's not forget that the heatsink is epoxied to the FET case, and it the heatsink weighs too much, it could literally tear the FETs off the board when running. If a super large heatsink is what you're after, I would fab some way of securing the heatsink to the entire ESC case. But really, if you need a heatsink that big to control temps, you are either using the wrong ESC for the application, or something is wrong.
