Now that is some outside of the box thinking ... I love it!

When you say MM, I assume you're referring to the Mamba Monster, not the Mamba Max that I just swapped in. So I don't even think the Mamba Monster is getting hot. There's so much plastic around it that it's hard to be sure, but the fan isn't switching on, and the plastic case feels cool to the touch. It's just shutting down momentarily when under load. So I assume some sort of internal fuse is flipping when the amps get too high, presumably to protect the ESC from flowing too many amps. Strange because I would think that heat would be a biproduct, but I'm not experiencing it. Things should dry up over here by the evening, so when I get home from work will try it today with a Mamba Max on 4S and see how warm it gets.
