I'm very critical, as it's what I do for a living for the past 11 years.

I do know that the Castle ESC's put out the power. Heck I still help peeps out from different states with their Castle ESC's for dragracing. So I'm not putting Castle down by any means. However, for 1/8 scale dragracing and speedruns(what I like to do), I want the most out of a ESC. That means proper cooling. As it sits right now with the two MMM that I have, heat dissipation is achieved by the fet board and that little patch of thermal adhesive to the heatsink. I prefer that all fets make contact with the heatsink. If you have an efficient setup, there wouldn't be a problem in it's current state. But I need max cooling in this Texas Heat.
