running the revo trans will save some $ because most have one with there revo, with the rc-monster motor mount and the trans locked in second , and batterys on the other side it is pretty well balanced if lipos are used, the revo spec slipper is the best option of the two, lower center of gravity, usually pretty light set up

the emaxx trans will have to be beefed up and you will need to get one , mounting batterys will be pretty straight forward, one on each side , slipper options are robinson racing (so-so) and the best would be a strobe slipper kit


personally i likes my stock trans. conversion better than the g3r/emaxx trans i run now, lighter and easy to work on
