I like the 989 better than the ice mainly because I wont have to buy a a seperate power source, and I can charge 2 batteries at once using a "Y" harness. What kind of upgraded diffs are available for the revo?
well depends on how far u want to go, i cant say because the mmm could be a lehner, or it could be a fieago.. the difference would be how much power is running through it
but if u want to go all out (i would just so u dont have to ever worry) mikes hybrid cases and 8 scale diffs but thats spendy
and idk who has the best cheaper ones, make a new thread
