Diff unit! Kyosho's diff is more similar to their nitro buggy, I think! I like the sealed type diff.. as I plan to add silicon fluid inside.. we will see how sealed it is soon.. ha!

Again, used the thick automotive grease on the edge to hopefully seal the diff, and in the middle, I filled it with 100k silicon fluid (from Team Associated) to hopefully create a LSD effect!
Just hope it does not leak out! 100k fluid is VERY thick, though... it moves very slowly when I was pouring it in.. LOL! Takes forever... ha!

Tricky -> the metal bushings were replaced inside the diff assembly, but I found that the diff unit doesn't fit the new ballbearings!
Turned out that there's another bushing mounted on the diff unit (the one on the left) so that had to be removed as well.. I guess it was designed that way so when there's wear in the future, that bushing can be replaced without changing out the whole diff unit.
No worry now, w/ ballbearings!! Can just change the ballbearings in the future if they ever go bad! (I highly doubt it, since I run my RC VERY infrequently, ha! )

I think this is the weak link in the design for the Blizzard (I am sure it will hold up fine, I am just picky, LOL!). The chain sporcket and the drive wheel are connected just by the keys on each side. Both pieces are plastic. And they ride on a hollow metal shaft (that's strong, no issue there) but without bushings. (Hence no way of changing it to ballbearings).
I think the reason for that is because the wheel speed for these Blizzard are not too high. Kyosho probably think the wear and tear will be minimal. Which is probably true.. but still..
The shape is complex so it is probably not easy to make (cheaply, I mean..) so I highly doubt that we will see aftermarket parts. Otherwise, this would be the parts that I'd change. Basically, larger diameter parts so you can fit ballbearings inside. And possibly make them in alloy so it is stronger.
