4S LiPo in a Yeti? I don't know what the battery compartment dimensions are...yet. I would like to think that a 3S pack will be plenty enough "juice" to propel that monster buggy/rock racer. I would do a www search, until somebody chimes in here who owns a Yeti and can give some insight, and see if you get any videos showing a 4S being put into that Axial.
