If they used an aluminum plate between layers, they might as well extend the plates fully out to the sides and attach a heatsink to them.

I still think those surface mount FETs are not the way to go; the plastic casing does not transfer heat that well compared to a metal tab type of device, like a TO-220 case. They seem to try to get around that by paralleling a butt load of FETs together. Then, servicing is a PITA; not too many people have soldering irons that can work with surface mount. I like small, easy to mount ESCs as much as the next guy, but I'd be willing to trade a larger ESC to get something more reliable and solidly built. Leave the light and tiny ESCs for the buggies, planes, helis, and any other small scale vehicle.
