im shure ball diffs were brought about buy a power to weight isue early gear diffs were quite heavy if i rember right and also quite bulky whare as a ball diff is much smaller and lighter ,as we now have an abundance of power and very efficent motors the weight wouldnt be as much of an isuse. but saying that when i built the diffs for my lrp s8bx the diffs in that are around the size of the diffs that i had in my chain drive kyosho stinger 1/10 nitro buggy around 21 years ago ? so we must have found a way of making them smaller lighter and stronger, techenology and materials will always evolve and normaly gose in some sort of circle ,we now have much stiffer much lighter alloys and much beter quailty plastics ,the same sort of quetions could be raisd about flat twin deck chassis vs tub chassis ,,,,
all in all id like to see a few more differnt cars using differnt from the norm materials like the durango on the market
