Looking good MC, im glad my original design is proving to be quite universal, since it seems like there is some interest in them, maybe we can get mike to take some interest, I have all the info for him.....I just need to know if he would be interested, and if there is enough people wanting one....so I suggest, everyone getting in contact with Mike, & we can go from there....

This makes me wish I never sold my diff from cowboy...

On a side note, hey Brian, you still got it?

It's been a long time since I've seen that avatar I never get tired of watching it.

Trying to get Mike to modify that spur gear like sjcrss did in the first place would be great. And the shafts are pretty simple to make also. I made mine using 6 mm stainless steel rod bought at Fastenal.com. The modified spur gear and the two shafts from Mike with a materials list needed to complete the diff would be nice. The only thing difficult part to get is the output gear from the Traxxas center diff. They still don't sell it separately. I wonder if the 3984X output gear would work? I have one coming to study it.

I sent Mike the original design info a few months back for the 4 spyder CD I designed, and i never heard anything back from him, I guess he is still real busy with the slipperdiff design, hopefully we can get his attention....and or his input as well.

hey sjcrss,
I thought I'd share this with you. I managed to get the TRA3984X gear to fit your Hyper 7 CD. It is not as pretty as the gear from the Traxxas ERevo CD but until they start selling that CD gear separately, it's a cheaper alternative than buying the whole ERevo CD just to get the gear.

yep, same shaft lengths. Only one thin shim needed on the back shaft to make it perfect. I went with four holes since the cap was already drilled and the holes were threaded. The back of the gear has 5 spokes so 5 holes lined up between the spoke could be done too. Question is, do we really want one more hole to drill and put threads in?

considering how much a PITA the 4 holes are....i think we are ok, but 5 couldn't hurt, as for me, i'll stick with the 4...

Took CD out just for a little TLC and see how it is holding so far, and here is the update.....
No leaks or loose screws, at all, the gear is holding up well also.
Bearings... no slop and still roll smooth
Internal 4 spyder gears, holding good as well
30k oil , a little dirty but that is expected, due to break in of the spyder gears
Shafts , are holding there own as well....very strong..
This is just a FYI, for anyone who is interested in the info

hi,

can anybody show me what parts i need for doing a center diff with a hyper7 diff?
i have a hyper front diff here and ordered a traxxas diff.
will the hyper diff work better than the traxxas?
what fluid will i need for racing with my e-revo brushless?
the traxxas have 500k inside, this sounds really thick for me.
