Andy's CC-01

Post by andymac0035 » Fri Mar 31, 2017 4:40 am

So I've been thinking about getting one of these for a while now (and doing lots of research)... finally got around to it. :)
I bought the CC-01 Bronco and some goodies to go with it. Tires on the left are losi-mini crawler. Motor is an RC4WD 80T. Full bearings. Alientac beadlock wheels (with hi-mass rings). RC4WD rock creeper tires will be going on them. I ordeerd tamiya CVD's, but they came late and will go on later. Not seen are a traxxas radio and an SCT sidewinder esc. There's also a hot racing steering kit in there somewheres... oh and a bag of traxxas rod ends.... lol

I got off to a slow start, due to work and chores at home. Started on the CC-01 this week and it's been slow but fun. I'm taking my time as this is my first CC-01 and also my wife is helping/learning as we go.

Locking the front diff took me longer than I planned. I did the free-mod where you add spider gears to lock the diff. Glad I read around a little before starting.... and glad I saw a post about taking a dremel to the back of the added extra gears. Initially I thought they just dropped in, but found that not to be the case. Hit the extra gears with the dremel and was able to get one on there just fine, but I wanted all three (six) gears in there (I wanted it to be balanced). After dremeling the living crap out of the backs of the 3 added gears, I got it all to drop in there.

Then the hot racing steering went in (such a great piece!), then went with the traxxas ball ends and shaved the stops off the C-hubs. I added some extra o-rings I made by cutting some tubing to better hold the dog bones. Took a few tries to get the right thickness, but happy with the result. My CVD's have not showed up yet, so I'll run the bones and see how they do before switching.

Sorry for the lack of pics at this point, but it's been a a battle with this build. That front diff took waaaaaay to long to get going.

Built the shocks yesterday, they went together nicely, very smooth. They have adjustable clamping style collars, but I decided to leave (all) the collars off and use a pre-load clip about half as thick in an attempt to soften things up (front only, nothing added to the rear).

Then I went to tackle making my 6000mah 2S lipos fit. This did not go as planned. I had invisioned putting it between the front shock towers, angled up towards the back to clear the steering. This idea just did not work in any practical fashion, as it would require shorties, and I don't have any of those type. So then I moved on to making the stock location work. Cutting the (oval) side entry hole square was not enough. These lipo's are on the large side for 2S hard cases, and they are getting old and a bit swollen, but they are 80C and have been great for me. Anyways, the case was like 1/16" too wide to drop all the way into the stock location.

What I should have done at this point was just remove the part where the stock battery retainer clips to, and lined the bottom of the battery area with foam to raise it up just enough for the battery to sit flat, and use spacers to raise the electronics tray. So of course, I went out of my way to NOT see the obvious easy way to do things, and proceeded to get the dremel out and cut away at things in the hope to keep that little piece of plastic that runs across the top of the battery opening. Needless to say.... I failed. Before it was all said and done I had removed the vertical piece (front of battery tray) that runs behind the motor. After hacking all that out and still not being able to save that other piece I was none to happy with myself. :evil:

The good news was that removing that (piece behind the motor) gave the room to put the battery all the way down in there and also slightly more forward, so that should help my COG. I still had to raise the electronics try a little, but I like having a big battery in there for the long trail runs I like to do.

From there I grabbed a turnbuckle and made a brace to replace the lost part of the chassis.

Notice the peice of hard foam under the servo. I've heard the servo can use some help as it flexes sometimes. This foam spacer has the servo sitting squarely on the chassis instead of being suspended.

So now I have to make a battery holder somehow. This is a large tamiya ball stud and a standard battery strap buckle pops onto it perfectly.

I shortened the strap by folding (and stapling) a section of it, and then wrapped it around my new chassis brace and it worked really nice.

So here we have it coming together. Hi-current wires and connectors on the 80T motor, sidewinder all programmed for crawling, CPE servo and a metal horn on there, and of coarse, my 80C 6000 mah lipo that was so much trouble... LOL

I used button head screws on the hot racing steering set-up for attaching the tie rods. Had to be careful to use screws that were just barely long enough, without coming out the other side and hitting the carbon fiber center linkage. I've seen other's have to dremel the skid plate below that, but that may have been for the GPM unit, which I'd heard bad things about.

I also took and trimmed the steering stops off the c-hubs and trimmed the side webbing too. I may trim the corner of the hub itself, but for now I'm stopping, as the dog bones seem okay with this amount of travel. I actually had to dial back mt steering servo some. This is limiting travel to right before the steering binds/hits the c-hub.

It's going to be a little bit before I can trim and paint the Bronco body, and I just happened to have this Hummer body kicking around, so I figured I'd give it a go.

Wow, Nice start Andy! Way to get that big battery in there too! =D> I just lid mine across the back down the center in the rear under the rear body post. Seems to work well their. The Hummer body actually looks great on the CC-01 chassis! I hope you add some scraps to it whiles testing just for kicks. :wink:

Thanks jeff, your build was one of the ones I looked at when researching the CC01. I really wanted my battery up front, but that just wasn't happening, so I settled for the stock location, keeping it low and as far forward as I can. This is going to see some serious trail-running... Or at least serious attempt at trail0running... LOL

After I get the Bronco body done I will figure out how far I want to go with the 'brick-mod".

So I finally got it out for it's maiden voyage and I got to say, it goes pretty good. Steering is waaay better than I expected. I trimmed the hubs a little more and now I pretty much have as much as I can get out of the stock parts. The carrier arm that holds the tie rod is bottomed out against the a-arm at full lock.... if I cut into that I could actually go more on my trim. As it is now, it feels about the same as my SCX10, which has stock steering other than metal links.... so I'd say that hot racing steering set was money well spent. I put some lead inside the brick and that helped a lot. Climb angle is really good, not as good as my SCX10, but not too far off either. Break-over angle sucks though....

Speaking of the brick....... that's gotta' go. I just have to decide how far I want to take things.
Also need to work on a belly-skid, as that got hung up a lot too.

The 80T motor is pretty darn slow, I think this may end up needing to run on 3S to have a balance of speed and power. Right now it's slower than my SCX10 (AE5/27t), but some times needs some grunt and also speed to "pop" up over things. Not really wanting to mess with a GRU, I think I'd put the 550 drill motor I had in my wraith in there first, but for now, I want to make this 80T work.

Took a shot at the brick-mod..... :shock:

I cut this out free-hand with a backsaw.

This is a front skid from an SC10. I cut the bottom half off and re-shaped it.

The 2 screw hole things lined up to fit inside the bumper hole mounts on the CC01 chassis helping hold it in place and line it up.

I drilled hole at a different angle through the skid and into the CC01 chassis.

Got some lead on the front now... in addition to the two 1/4-oz pieces on the inner fenders, there's ten of those 1/2-oz lead squares in that bundle, and two more down below. That's a long screw from a clodbuster "shock", as well as servo horn, and another clod-bit under there wedging the two pieces down below, and the screw going into that middle hole in the bottom of the chassis for the stock bumper/skid.

I like plastic vs aluminum for sliding over things whenever possible. Not sure if I want to cut the side bits off yet.

That should help my approach angle! :)

I'm pretty happy with how this came out and can't wait to try it out.

Looks good Andy! I like the slight brick mod as well. I took way more off on mine then you did but I think yours will provide the same approach angle regardless.

Your 80T motor sounds like the same issues I am having with my GRU set up. Its slow but crawls over a lot of stuff my SCX-10 does.

I'm liking this build!
Iv'e never seen a CC-01 before in this much detail...really cool. The Hummer hard body looks right at home on there too. The outdoor photos on the rocks make it look like the real thing.
So is wide open with an 80t motor a brisk walking pace or even slower?

Thanks! I'm still going to have the Bronco body as well, just have to get it painted up.

It's still at least a brisk walk or faster with the 80T motor as these are geared too high to start with.
It goes pretty slow what you ask it too though, I plan to try is with a 3S at some point to get some wheel speed for when I need it.
