The Strongest Savage Diff Compilation.

[Jahay]

yep champ hit it right on the head there...

i think i am deciding to stick with the IRC cups as i can get 3 for the price of two nova cups...
BUT THE PROBLEM IS ... irc said it will be a few weeks before they have them in stock!!!
No biggie i hope, i have a lot to do on the truck anyway... But i will be running the Hotbodies inteernals, and hopefully they will work perfectly without any shimming whilst using the BP Ring gear.

on the Nova Cups. $6.50 a cup>? WTF! I just got one like a month or 2 ago and it was $18. I literally just bought 3 more LST cups. Glad I stopped in this thread.

BTW the Nova cups are damn sweet. If shipping is too $$ just buy a couple extra and sell em to get some $$ back.... @ 6.50 you can tripple your money back...

I did a CD mod to my Maxx and I used an LST Nova cup and 8ight-T Spur... It has been holding up fine for the first month... (EDIT on 6s with a 1717 and my ride is ~13lb)I cant say for sure that it will be an end all cure to stripped diffs, but I will say that I trust them more than the plastic cups. as you can see what I mean here: http://www.rc-monster.com/forum/show...t=28180&page=2

I will put one on my 8ight buggy CD and the Maxx' F/R diffs now as well.

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!

I was shocked too when I saw the price on ebay. but then i notice that the type of aluminum has been changed to 6061-t6 instead of 7075-t6.. perhaps the price is reduced because of this? i already sent them a msg asking about this. will update once i receive the reply.

All you can do now is pray, may God have mercy on your soul...

Didn't notice they changed the type of aluminum.
