1st Generation Ultima CVD Question

[Diggley]

Has anyone perfomed an easy (no mod) installation of MIP CVD's for the 1st gen Ultima?

What fits?

Are there part #'s available for a conversion?

I know there was never a direct fit set available.

I'm sure I've seen the mod in another post, but I'm not sure which one.

I'd like to adapt a set to my Ultima Baja conversion. Besides the fact they eliminate most of the slop, I love how they look on a scale project.

i used the ultima RB5 axles with stock (original) ultima rear hubs
i dont know if i have any close up pics but here is my build thread

Thanks!


So the RB5's will fit with no issues?

Oh, by the way...sweet car!

[mikedealer]

thanks

yes they fit no problem, make sure its the stock rb5 axles, NOT the world's rear axles, or the lazer zx5

they fit no problem, but need a spacer (comes with complete set. I suggest the hopup clamp on axles, works well

Alright alright... The RB5 cvds form Kyosho are $50.00 I cannot seem to find any made by MIP either. What other options do we have? I'll convert hubs/bearings to something whose offset matches the original, just to get something more standard on there. Seriously, $50 bones? That's TWO sets of CVD's!!!

When I get home, I;m going to compare my RC10 universals axle length to the Ultima dog bones I have. There's got to be a better/ more cost effective way!

You will need the 62,5 bone and the shorter la231 axle then you will have exactly the same lenght as the w5061.

Mip did sell uj´s but they where listed as "for inferno 10"

I actually prefer the longer axles and adding a spacer: this compensates for the offset loss with 2.2 RB5 wheels.

The CVD's are nice but on my last off-road race (phew, already almost a year ago) they were the items failing.
The crosspin inside the CVD part came out! I know a bit of threadlock should fix that...
But for me, the cheaper and reliable way is: plain old dogbones and a HPI rear axle: direct-fit plus it uses a crosspin for fitting hex, and the hole for the crosspin is further out so it allows adding a spacer just like on the CVD's.

Thanks isobarik and Mr.Ed. I probably should have been more clear. I'm trying to avoid using expensive kyosho universals or parts period. I should also say that I want to use the same duratrax nitro evader rims I'm using for my RC10. (I looked, and it looks like the offset is similar to the ultima rim.) I looked at my RC10 Universal, and with a RC10 hub it would work, but I'll have to do a little modifying to get it to fit in th outdrive better. Prooblem here is that I lose some width. Any other ideas?

[Mr. ED]

I think the biggest issue is the spherical part of the CVD won't fit your ultima outdrive cups.

There is at least one other drive cup , I think it's from HPI but not sure, which bolts on the geardiff axlesand is lightly larger inside; so that works with RC10 bones. But if you use the balldiff you're out of luck.
