Havoc heat sink Mod.

[BrianG]

Another modification I personally would like to see is to have the FETs facing down and attached to a heatspreader. If using a traditional heatsink, it can be attached to the heatspreader easily enough. But for people using aluminum chassis, you could attach the heatspreader part of the ESC directly to the chassis and use all that surface area while making the system as low profile as possible.
