Cain: It's all but impossible to compare the amp draw of different motors because there are so many variables to consider. But if you have two identical vehicles (gearing, weight, voltage, etc), a lower kv motor will pull less current, but at the expense of speed.
cobrawes: I don't know where to find a motor at the moment. Your best bet would be to contact Mike and ask him directly...
Will do. By the way I do hav an 8000mah 4s lipo that should get me the 30 minutes, but it is a little heavy. By the way I found a 1512 2d. can't find a 1512 2.5 d
