20 years ago all diffs were geared, then it became popular to have a ball diiff (because they were apparently better) funnily enough geared diffs have made a come back and they are now even better !!
Like everything in the rc car world it follows fashion and there are plenty of folk on here that believe all the hype and nonsense to get them to spend even more money on something they feel the must have to be the next world champ !
