CC-02: post build thoughts

Recommended Posts

Awesome info here! Makes me look forward to building my CC-02 Unimog! I want to set up Magnet Mounts so I can swap my Landfreeder Body from my CC-01 - which has been a huge money pit over 12 years! But I've got a lot of details on that Body, including Full Light Kit. 

Is there a decent, Axle Mounted Servo kit for these yet? Possibly a VERTICALLY mounted Servo, for space issues?🤔 

I think there's a thread in the builds section where someone prints an axle mounted servo bracket - but I've had a search and the link escapes me (but I'm certain there's one somewhere!)

@Frog Jumper THANK YOU! I'm sold!! Now I just gotta FIND them. And figure out what size for a 95mm Tire....

@BuggyGuy THANKS!! I've got a Sovol SV02 3D Printer that I still haven't figured out how to even TURN ON!! 🙄  But at some point that will be the first thing I try.

I bought “large”, which were about 3.5” diameter and 1.5” thick.  Like I said they were too big for my 1.55s.  I’d like to try “medium”, but I’m having second thoughts since I will have paid about $50 for all of it, and I can get WP lazerfoams for that much…

Yeah no kidding.  This all started when I started searching for waterproof tire foams.  Regular foam acts like a sponge when it get wet and I’m planning on getting my CC02 very wet.  My search turned up LazerFoams which are ridiculously expensive, and it also turned up that video.  After shipping, 4 donuts cost me $24, which I can stomach.  Too bad they didn’t fit…

That's not awful. Those might be great for my Wraith. Maybe I'll try Medium...

I'd also consider these closed cell foams from Crawler Innovations, they are the same type of material as the laserfoams (closed cell foam), and slightly cheaper from what I can tell. I've used these on a crawler that regularly got wet and they held up just fine. https://www.amainhobbies.com/crawler-innovations-deuces-wild-1.55-single-stage-closed-cell-foam-2-cwr-3019/p718534

My experience with Closed Cell Foam is that they tend to be pretty stiff.  What did you think???

They weren't too bad, but I was using a pretty soft compound tire. I've never used pitbull tires, so I can't say for sure if they would be too stiff, but I was also running them on a truck that was about 7 lbs.

I agree.... hard as ROCKS, not allowing any Tire Conformation on uneven surfaces. Hardcore Crawlers here in the Colonies like them for their heavy Rigs.... 

A CC-02 is anything BUT heavy.

I've run them on my 12lb Wraith, with pretty good results.... EXCEPT on Sand, they were terrible!

So I’ve given up on foams for the time being…

In the meantime, I’ve adjusted my wheelbase from 242 to 247mm by flipping the front link connections. The BF body looks better with the slight change and I didn’t have to move my shock towers or body mounts.

My latest focus has been axle steering.  @Bash did me a huge solid by 3D printing @eness76’s plate.  But it’s too brittle…

 Here is a pix with my servo taped in place.  I need a low-profile servo ($90) or I need to do some minor mods on the chassis center plate (free or cost of replacement parts tree).  I’m leaning towards surgery…

During Little Zoey’s last bath, I noticed the front drive shaft was starting to twist. Unfortunate…

The rear doesn’t look as bad.

The biggest issue with the kit CC02 shafts, at least in the Defender kit, is that the front shaft is too short.  Even at 247mm, more  of the shaft is revealed than should be.

I elected to fit steel hop-ups.  CR01 85mm shaft in front and CC02 75mm shaft in rear.

Once I removed the kit shafts, I found the twist was much worse than it originally appeared.

Front:

Rear:

CR01 shaft:

CC02 shaft:

The instructions are nearly identical in case anyone is interested.

Rear:

personally, I recommend these hop-ups.  They are nice and smooth.  And the 85mm fits perfectly.

Indicating the 75mm doesn't?

I must keep an eye on mine especially as I’ve put a fair bit of weight into the front wheels/tyres!!

No intentions whatsoever, just wondering. As far as I can tell from the pictures it fits perfectly as well.

At 247mm, about half of the fluted shaft is exposed (and does nothing), leaving only half of the shaft to do all the work.  I felt it was too short, even though it does span the length required.

Looking back at my photos from when I had it set up for 242mm, the 75mm shaft fits much better (and IMO is the appropriate length).  Only about 1/4 of the fluting is exposed (similar to the rear shaft I have pictured above).  

Just be aware...

Yeah, I've added a significant amount of weight to my CC02...

Terry, any more pictures of that Axle Mounted Servo setup? I'm hopefully FINALLY getting started on my CC-02 Unimog... I might be able to make something like that! 🤔 

..... since we're all scientific here! 🤪🙄😅😂🤣

Thank you again! (IF I forgot the first time!)

NOW I need to beg someone to print one for me... or two. In case I get a second CC-02, or I just SCREW UP!! 😵🙄

Carmine, it’s not hard to make your own.  I used a length of 1/8” aluminum, a hacksaw and file, and a drill.  I added some inserts from the ORV tranny and some servo mounts.

ETA. Looks like I said this already…. I’ll try to snap some more pix and take some measurements this weekend.

Thank you Brother! ORV "nut-serts" I thought so. 😀  I've got a spare Axial Wraith Servo mount plate, that might just work! The extra pix and measurements would really be helpful. Thank you!
