Keep in mind though, one of the big differences with place ESC's is that they can't handle the high amp burst like the MM for example (100 constant, 200 burst I believe).
I would just stay away from them... and what's up with the guy who decided to put a small heatsink on the FETs, and then shrink-wrap over top of it!
