Thanks guys!
Well actually my question is around driving a 1/16 scale off road Kyosho Mini Inferno on multi surface (but mostly carpet tracks). I have 2 complete sets of diffs - one sealed metal geared set such as those found in the 1/8 RallyX cars and I have a set of ball diffs.
The ball diffs are quite a bit lighter and so I have been tempted to go back to ball diffs for weight saving. I originally moved to metal geared diffs for reliability as I tore out 2 ball diffs.
I have seen people talk about running a ball diff in the back with geared diff in the front and all sorts of other combinations and so was wondering why and if it's worth going back to ball diffs for the weight saving? I guess if there isn't that much of a difference then I might as well go to ball diffs, save the weight, gain more tunability?
