The Strongest Savage Diff Compilation.

[FG101C]

Could have swore I posted that I had three nova cups in my Losi 8T, with about three years of hard running and they are still fine.....

Yea, you did mention having a Losi Truggy. I didn't have a clue about Losi models and wasn't sure specifically which one you had. Just googled the 8T diff cups and they are indeed very similar to the Savage ones. The sleeves on these cups that the bearing sits on are 1mm thin. It amazes me that the 7075 alloy can be milled down to 1mm and still handle the kind of stress these monster trucks dish out . . . WOW!

I'm sold FG101C. So far so good on my plastic cups, but as soon as I ware those out, I will try the Novas next . . . if they start using the 7075 again. Check this out: (link)

I think you will like them, I'm going with the stockers for my build and upon detonation I will probably do the nova's with HB internals, or unless you find and even more reliable diff setup.

If you think about it though, they don't have to be very thick. The inside bore is filled by the outdrive shaft, and the outside is supported by a bearing. You might be able to crush the sleeve easily with a set of pliers, but try doing that with an outdrive in there and you can't. The joint where the sleeve meets the rest of the cup is probably most at risk of failure.

Hopefully Nova RC switching to 6061 is a good thing. Maybe it means they tried both alloys and found the 6061 is plenty strong enough, and it's cheaper so they can pass savings on to the customers. I don't know how long ago they switched, but I'm pretty sure the nova cup I have is the 7075 as I bought it quite awhile ago.

But yeah Jahay, I'd say IRC are definitely the way to go for you, especially with Nova now using 6061. Not sure on how the Hellfire cups compare to the Lightning Stadium cups. All I know is Jammin, Kyosho 777/ST-R/GT platform, and HotBodies LSP/D8/D8T are all basically the same.

That joint is specifically the area that I'm concerned about failing because it already failed on me twice with my home brew milled down Savage cups after only a few runs. But FG101C has had very good success, so Nova must have figured out a way to reinforce that joint.

I've already got more run time on my plastic cups then I was able to get out of any of my stockers though, so it's all good! And the price was right, got 4 of the HB cups shipped to my door for $20 off eBay. I'm also running the $3.90 8x16 Boca Ceramics to further reduce maintenance needs. The 10 packs are the way to go!
