The 1/18 scale ESC looks like the one I was using on my MLST. It is the same 25A rating and has the same heat sink and little capacitor. The ESC I have is really nice and has an ABS setting that is amazing, but it overheats really bad. It will melt the plastic casing and in my case some components actually unsoldered. I was told not to use the stock MLST pinion and go with something smaller.
