12 cell Rustler

You could go cheaper and use the MGM Compro 8012, the 12012 is overkill. Depending on the gearing, you can expect 50mph for sure in a straight line. In a 2wd 1/10 stadium truck, speeds higher than that are just stupid! I've hit 57.6mph on 4s Lipo with this motor in my Rustler, and could hit higher if I have better range.
