I run a KMRC converted Kyosho Mini Inferno which has a good quality adjustable slipper in the middle (and it has done away with the centre differential). The geared diffs I have are made of metal and quite heavy compared to ball diffs but they are bomb proof (reason for getting them in the first place!).
So it seems a good idea to start with a geared diff in the front and ball diff in the back to see how it goes. Or if I am to use a ball diff in the front then run it a little looser than the rear without it slipping?
We run on multi surface tracks with jumps but so far the tracks have been at least 75% high grip carpet so that is probably the surface that I need to tune for?
