Can you post a photo of the model, especially the steering mechanism? Might be a mechanical issue with underdesigned steering mechanism.

The outputs ("power holes") are placed in the rear between the single holders, they are driven by red colored gears, which makes sense with the PU system. In the rear between the mechanical outputs I expect to be a usb C charge port.

No, according to the official documentation. What scale do you expect the model to be? I think it's going to be too big for 1:16. so I think it will be 1:12 or so.

So it appears the hub has integrated motors AND LEDs, so I expect some fiber optics or such.

I chose this set, cause it's one of my favourite official sets, I really like the styling, functionality and details @grohl managed to cram into it. Started working on this idea yesterday in LDD, currently some 50% done, please note that not all colors are defined yet. It will feature all of the functions from the original 42069, here you can see the fake engine: And of course, the intricate door opening mechanism which I still have to test IRL: Still have to finish the tent-lifting mechnism, rear slide-out drawer and the rear doors. The only issue was with that I had to replace the purple with another color, so I chose Dark Azure, but other than that so far so good.

From my experience 28 tooth bevel gear inside the 7x11 frames wth axles supported inside and outside work the best.

Used them for work on modified Audis and in a custom made rally car, no issues so far. They have a very simillar overall deisgn to the planetary ones, the weak points are the side walls which eventually wear down, thereby increasing slack. But as said before, they are order of magnitude better than the standard ones and I hope to see them used more often in sets even if they may not be needed.

Many people have been asking me for a simple, easy-to build and most importantly cheap Off-Roader. When I started this project, I've set myself the following guidelines: Use a single BuWizz 3.0 and "only" 2 BuWIzz drive motors Implement a 2 speed gearbox Maximize the ground clearance by using a pendular axle (this way the independent suspension doesn't have to loose ground clearance when going over obstacles) The model has to be built from under 500 parts All the parts have to be standard and in current production Keep the number of different parts as low as possible Use color coding to simplify the building process Design the model so that it can easily be modified by other builders Create proper building instructions And this is what I came up with in the end: I managed to successfully realize the all the planned functionality, features and more: All wheel drive 2 speed gearbox Pendular front axle Independent suspension on all wheels Openable doors for easy acces to the charging port Interior with seats and a steering wheel The dimensions and specs are as following: Built out of ~460 parts 27 x 20 x 13 cm ~ 850 grams Top speed of 7 km/h As usual there's a video showcasing the model in more detail: But just building the model and recording the video was only half the story. I also taught myself how to create the building instructions using the Studio which can be found here: https://bricksafe.com/pages/Zblj/simple-off-roader Since these are my first such instructions, they may not be ideal... So in a case of any issues, confustion, or such I also uploaded the .IO and .LXF files which can be found in the corresponding Bricksafe folder: https://bricksafe.com/pages/Zblj/simple-off-roader All in all this was a great learning experience, I'm always happy to learn a new skill and being able to create my own instructions sure is a good skill to have as a LEGO builder. To conclude; using this as a base, I wonder what kind of tweaks, improvements and crazy mods other builders will come up with!

Brilliant use of the L connectors for the grill. Very clean shapes and efficient chassis too. Hope to see it IRL one day!

You can use toggle joints 32126 to make any size of an engine using half pins.

Or you can use the new one from the Audi. Either way, good job!

10317 and 10327 come to mind.

Not if you use a 28 tooth gear to drive the diff

Oh, my bad. Then we can expect the parts from the Kawasaki.

A good thing about V6 is that it could be built from normal parts and still fit, hopefully.

8437 or 8473?

The original G500 uses normal hubs, only the squared version uses portal hubs. So if we're lucky we might see Audi's hubs in front.

Nice to see you still building these small cars. It sure looks like a fun, little and well shaped model.

I hope that the rear axle is not supported directly, but by via a control arm, so this way you get more suspension movement.

I expect it to have more or less similar functionality as the Defender, hopefully with the new gearbox and engine parts to run smoother. Since it's a 4 seater, it will probably be the biggest and heaviest 1:10 model so far, so I expect the 9L hard shock absorbers in all 4 corners.

Well done (again), Lipko! Love the video showcasing the suspension, those new shock absorbers seem perfect for such models.

Here's a fun little project I came up with while trying to find a way to build the smallest AWD model with independent suspension. Having found a solution I decided to build a representation of the awesome Audi S1 e-tron using a 3D STL file purchased online. I set myself the following functionality and features as goals: All Wheel Drive Proper independent suspension on all wheels Each wheel powered by one BW motor Working steering wheel Detailed interior with proper seats and details Easy access to the 2 BW bricks powering and controlling the model Deisgn the body to be accurate to the 3D reference, yet robust Part count of 1200 or less With the goals set, I came up wih this prototype in LDD: The next photo is showing just how close the model is following the reference 3D model in green: And here's the model in real life, built out of exactly 1200 pieces: I took full advantage of the new micro panels, so there are almost no flat/straight surfaces in the model: Finally the belly photo showing how I used brick-built CV joints in order to keep suspension and drive system as narrow as possible. And yes, those are rings from LOTR sets I will post better photos and a video as usual when I find the time. For now I can say that this thing has a really high power-to-weigh ratio and it can easily spin all wheels when accelerating.

This model (and it's prototypes) are a result of the following topics: Basically the idea behind this project is to make an offroader capable of driving on all kinds of terrain with a simillar perofrmance as the Wildcat 6x6 but having a lower weight So, why would I want to reduce the weight? While the wildcat 6x6 works great most of the time, it's high weight of 2,5-3 kg has some drawbacks: The model requires a lot of expensive electronics (12 BuWizz motors, 6 BuWizz 3.0 bricks) High part count (1869 pieces) Tendecy of front wheels falling off at hard landings High wear and tear of the individual components, which lead to premature failure - planetary hubs, CV joints And lastly high wear and tear of the handler due to it's heavy weight Of course decreasing the weight also means decreasing the power to weight ratio, since there will always be components which are needed regardless of the number od drive motors like wheels, hubs, steering system, suspension and frame. The first protoype, which I simply call Light 4x4 used only 2 BuWizz motors coupled to a 2 speed gearbox: While the model worked good in low gear, the high gear proved much trickier. The single gearbox put a lof of strain on the drive axle in high gear, causing it to melt, even with lubrication. Another issue was the high load of the motors in high gear, resulting in them overheating, while the motor could not even remotely apporach the 15 km/h top speed of the Wildcat 6x6. But not all was bad, I really liked the free-moving front suspension which acts like a suspended pendular axle, while having a much lower unspring weight. While I could make the rear suspension act like a pendular axle instead off front, i decided agaisnt it, since most of the weight is shifted back when crawling and I wanted to keep the rear stable. With that knowledge, I went back to the drawing board and decided to up the power for the next version... Medium 4x4 prototype: This version used 4 BuWizz motors coupled in a manner simillar to my 1:10 Acura NSX which negates the sideways load on the output axle of the gearbox. As you can see, this version was quite bigger and it used the reinforced differentials. The increased power drastically improved the performance, the top speed and overall power being simillar to the Wildcat 6x6. BUT the model had a few problems, main being the exposed gearbox which would get clogged and jam while driving outside. This version was aslo wider compared to the first prototype. Medium version prototype 2: This is another concept where the entire front axle is designed to pivot, but I ultimately decided to go agaisnt it due to the higher center of gravity and higher unspring mass. The final, universal 4x4 model: I have built and tested the model, but have yet to make any media, that's why I'm using LDD photos for now. I had to way to make the model more ingress resistant and narrower. This is where I came up with the idea of using the new, reinforced differentials as 28 tooth clutch gears for the high gear of the gearbox: This way the gearbox's output axle was moved a stud lower, allowing me to cover the bottom of the model with panels which prevent the dirt from getting into the gearbox without sacrificing ground clearance: The model inherited the front axle from the prototypes which acts like a free pendular axle. This keeps the weight even on both side of the suspension sosimple open differentials sufficed without a need for lockers. The gear ratios are a bit of a compromise comapred to the Wildcat 6x6, with low gear being 0,89x the ratio and high gear being 0,83x the ratio. Even with these differences, the model still reaches a very simillar speed in high gear, probably due to lower friction losses and lower rolling resistance. All in all I think this is a worthy successur to the Wildcat 6x6, even though it may not be as flashy, massive or functional (no skid steering). Final part count is 774 pieces which is 41% od the Wildcat 6x6 and the weight has been reduced to around 1,4 kg - around half of the Wildcat 6x6. I will be creating a proper in-depth video about the finished models and the protoypes, so I suggest you to watch this space for more upcoming details.

I think it should be easily doable, you can skip the 16 tooth gears in such case.

A version of the app with that functionality is available on support website.
