Drive cups breaking

[AlvaSpeed1]

I have a chimera that has broken 2 drive cups.


Part # 07145


Anybody with the same problem?


I think the problem is that the rear suspension up travel is too long that the dogbone´s angle is such that it makes a lot of pressure on the drive cup edges and breaks them.

All the Redcats are prone to cup breakage. Many guys sleeve them for more durability.

Upgrade them.

FLM makes good durable CVDs

+1. I've bashed my XT harder than I probably should and I have yet to have a drive cup break. Last incident I barely clipped a tiny stump. It ripped my 7075RC hub right out of the carrier breaking the hub carrier and ripped the CVD right out of the cup AND even knocked the sleeve off the cup. I'm certain had that sleeve not been there, I would also be replacing the drive cup too.

Sleeving is cheap and easy. If you have issues after sleeving, then I'd think about upgrading.

What actually is sleeving them?

I remember a couple of years ago I got a sleeve kit that came with glue and everything.

That worked great but got discontinued.

Is there a kit for the Chimera?

There are guys doing it themselves with copper tube, I did mine with carbon fiber tube or 7075rc sells them done! http://www.7075rc.com/xt-1/ I am assuming the xt ones are the same as chimera, someone can chime in and correct me if not

I got my carbon fiber tube 20mm id off ebay for 20$ free shipping just sand the drive cups and inside the carbon tube and apply thin tire glue then your good to go

Has anyone had good luck using the hardened drive cups instead of sleeving? I haven't had sold many of them so not sure if they are any better than the stockers.

Definitely not a permanent fix. Sleeves are the best option.

My hardened ones are holding up for now. I think that the problem isn't the cups as much as there is to much twist in the a-arms. I hate to go aluminum on the arms but I think sleeving and new 7075 arms may due the trick.

This is my theory due to I broke Fastlane machine drive cups as well, which is hard to do.

I have those cups, and I did manage to break one....

Not at the cup but where the pin goes.

I think the stock drive cups when sleeved are better than the hardened version because the metal around the pin should be able to flex a little as there is a lot of stress going through the pin and shaft of the drive cups
