This setup is used in set 42055 (Bucket Wheel Excavator). You can look up and study the building instructions to learn more.

Me not yet. I only came out of my dark ages a year ago, been building up my parts collection and MOC to-build-list since then. It's a long list but your Großer Mercedes is definitely on it.

Aren't you worried that spreading the link will actually increase the chances of people buying the knockoff?

I for one love the new bodywork, curvy and edgy at the same time!

If you insist on retaining the half-bushes, simply replace my blue 3L pins by 4L axles, fix them with those half-bushes on the outer side, and fix them with a thin 3L beam on the inner side (on top of the pulley wheel). Another pair of half-bushes can be used inside the contraption. https://rebrickable.com/parts/98585/hero-factory-weapon-barrel-with-2-pin-holes-and-3-axle-holes/ I considered that, but indeed it won't fit.

That's simply due to part 6553. Need to get rid of those. How about so: https://www.dropbox.com/s/o8en6862ge5jreo/hub0.jpg?dl=0 https://www.dropbox.com/s/h9p5ex2q7odn2ko/hub1.jpg?dl=0

Ah I think I get it. What I meant was that, in this picture, the female part (in darker gray) can be pushed further into the red #2 connector -- further inside the wheel. If you push it all the way, its axle will go fully through the wheels axle hole. But I think your point is, that this cannot be done, because then the pivot point would be too far inside the wheel...

Update: still working on the instructions; progressing slowly but surely. Even in case of utter failure to produce step-by-step instructions, I can resort to publishing the virtual model as is, so anyhow I'm positive y'all will get something to build! With that in mind, let me share with you the inventory: Rebrickable parts list If you're eager, you can check already if you have enough parts, and start ordering otherwise. For your convenience, here the list of parts used by the Koncept Mantis that are not in the orange Porsche: Inventory minus set 42056. As hinted in the topic title, the overlap is 90% This inventory does not include any power source (I'm using 2x BuWizz, which is needed for getting 'ludicrous' speed), but there's enough space in the cockpit for battery boxes and IR receivers. In the next few days I'm also planning to share some photos of my physical build. And later also a video of how it drives.

I just tried putting the long female CV joint from 42099 into the hub, with the red #2 connector in between, and it actually extends fully into the wheel's axle hole. So from what you're saying, it sounds like the female CV joint is (slightly) coming out of the wheel when driving?

@amorti is the turning radius affected at all?

Although I sunk quite some time into reverse engineering the model, it doesn't feel right to charge money if it's not my design. HOG steering should be easy to mod, given that the model is pretty much empty if you take out the motors and batteries, so you shouldn't have any trouble finding space. Great, this is a very useful pointer! I installed LPub3D and that looks like magic indeed. I'll be playing with that for a while... I'm planning to shoot a video showing how fast the model is. For that I need to go outside and find a flat surface. Both are hard right now here in the Italian Alps... In the next few days I'll post an inventory so that interested people can check ahead for missing parts. But if you own set 42056 (the orange Porsche), you'll have 91% of the pieces already!

Thanks! In fact I constructed the virtual model first, in order to verify my understanding of the model's construction, and to get me a parts list for ordering missing pieces. I'm not a great photographer and I already have the virtual model anyway. I've seem some beautifully rendered instructions by others, and I'm interested to learn how that's done. I'm scouring the web for resources on that front, but any further hints and pitfalls are greatly appreciated!

===== 2020-05-17 UPDATE ===== New acceleration and racing footage! Finally after 2 months of corona lockdown it was possible to go out and record better the speed of this vehicle! ===== 2020-04-29 UPDATE ===== Free building instructions are now available on Rebrickable! ===== 2020-04-23 UPDATE ===== I've published a little video of my physical build. There's a little acceleration test at the end, but more racing footage could not be shot yet, due to the lockdown where I live. And yes, my apologies to the purists who don't like painted parts... When built in orange, 90% of the parts can come from set 42056 (the Porsche 911 GT3 RS). Building instructions are virtually complete, currently being reviewed by the original designer of this beauty. ===== ORIGINAL TOPIC ===== Please allow me to grab your attention first: SamBellCar-23 by R. Skittle, on Flickr I fell in love with this creation upon seeing it featured on http://www.thelegocarblog.com and resolved to build it for myself. I succeeded in doing so using the photos from R. Skittle's flickr album, and a few kind hints from the designer himself. I've even given the model a speed upgrade: with 4 PF L motors propelling less than 1700g, it's blazing fast! Moreover, I built a virtual model in LDCad (.ldr), and with the designer's express approval already granted, I'd like to have a go at making and sharing building instructions. This is the first time for me. :) Now my request: I'd love to hear any experience, pitfalls, and hard lessons you've learned trying to produce high-quality PDF building instructions! Any and all pointers are welcome.

Oh my, that escalated quickly!

I can't believe I missed this earlier. This is so beautiful and creative! Indeed a welcome and fresh change from the usual vehicles.

Now that I can relate to... salute!

It's a matter of necessity. The next morning you never know which parts the kids are gonna "borrow". Those left in sight on the desk are most at risk, but would also be the ones you'll need most. Better to sort & store everything and distribute the risk.

After each building session, I put all lose parts back into the hardware organizers, and all partial assemblies go into a big drawer. My desk is always completely empty overnight.

That makes a lot of sense!

My literal thought process: Oh wow that looks aweso- AAAHH IT'S GOING THROUGH THE MUD AAAHH

Holy fork, that's fast! What's that sticking out on the sides of the bike though?

I love it! Besides the electronics, does it use only or mostly parts from set 42082?

Awesome! Got 'em, thanks!

The efficiency and effectiveness of these builds is very inspiring! We would love to see those 3D files indeed!
