Hi,
I couldn't really find a topic where this fits in, so I started a new one.
First of all, few weeks ago I started to get interested in F1. One at our club has an F1 with a ball diff which is sooo smooth and allmost doesn't slip at all. I started wondering, what the hell, why can't I get it like this on my MR02. I read here somewhere that the diameter of the gear is bigger, and that the balls are further away from the center and that helped to make it slip less, though keeping it smooth.
Now, also a few weeks ago I noticed that PN brought out just another delrin gear for a ball diff. There was nodthing special about that. Also ATM brought out a complete new ball diff for the MR02, I didn't really see any difference, except some small changes. Until today. :)
It's stupid, but suddenly I noticed that the 1) the PN gear had more holes then the previous ATM one. It went from 6 to 10. 2) If you look at the rebuild kit that goes with the new ATM ball diff, it has 10 balls too.
I don't know who was first, but it is clear they learn well from eachother. :)

Anyway, my question now is, has anyone tried one of these diffs with 10 ball? Is it smoother then the 6 ball versions? I can imagine that it will become heavier and that these ceramic balls are become more interesting too. Will it make my ball diff smoother to, with less slip?
Also, a very hard question, can someone tell me what grease is best choice to rebuild my ball diffs? I tried several here at home, even tried dry, but allways have different results. The best one now is no longer available anywhere (some grease that was laying around on my desk ;) ).
