The motor just came to life, and the bottom end pulls waaay harder!! The first column of numbers is the standard drive numbers, and the second is the numbers for the improved internal drive. I also undertsand in afew months Team Magic will be offering a still lower internal drive. Some of the prototype stuff I saw was really really trick!!
