Can anyone recommend a book or web site that explains it all [electric information] for someone new? Something that explains how you figure out what size motor and battery you need... I'm playing around with MotoCalc - but I think that is more then I need at this time - just a buch of numbers... would like to learn how you size a battery to a motor and especially what all the numbers mean for a LiPo battery (i.e. 3S2P).
