I made one here:

I use LDD. The great community here found a way to update it with new parts and you can import any kind of a 3D geometry which can be used as a reference.

In this case performance isn't really THAT huge, the modified 42115 had twice the power, but it should be still enough for fun driving. The porsche's wheels are a perfect match so I see no sense in 3D printing any custom wheels. For the color white with 42096 covers in the back, not sure about the print for now.

More like having A model instruction in digital format only.

I already did this before as long as you give it enough room there is no problem. Why would building it in LDD be difficult? Plans is to do both, LDD and real.

Having recently gained a few experiences modeling complicated shapes in LDD using real scaled models as references I got an idea for something different. There's been a plenty of manual 1:8 models and there's aslo been plenty of motorized models, so this inspired me to do something different. Why not make a hybrid? Here's the basic idea: Have the front wheels driven by electric motors while the rear one drive the fake engine via the usual paddle shift gearbox. The model can be used in a manual or remote controlled mode. This is why I'm using PU motors for steering, they are easy to drive back manually unlike the PF servo motor. In manual mode you can easily push and steer the car and shift gears like any other mnaual supercar. Once both BuWIzz 3.0 bricks used to drive the car are powered on the model can be remotely driven like an RC car. After looking up several real cars online I decided for the Mercedes-AMG one, because it has the perfect architecture I wanted to replicate: I managed to find a free 3D model and import it in the LDD and started building starting with the front axle. The front wheels will be powered by 4 BuWizz motor via 3:5 gear ratio. This will give the model 35Ncm torque at around 1200rpm allowing for top speed of around 18 km/h. The front suspension is replicated after the real one this particular car uses. The car uses a special mechanism to seperate the forces acting on suspension, more info in this video: I managed to redesign the front suspension to be compact enough to just fit inder the hood: Here's a view of the front axle with the 3D reference model hidden. The CV joints from 42099 are used to carry the massive torque involved with accelerating and stopping this model: For the rear gearbox i plan to design it so it's slightly different than usual supercar geraboxes. The power will first go to D+N gearbox and from there to the 8 speed paddle shift gearbox. This way the whole gearbox can be totally dissengaged increasing the efficiency of the model when in remote mode. And since this is a hybrid the reverse gear is not needed, additionally simplifying the entire driveline. I think this a good project to further improve my modelling skills and to do something new and different on the Lego suspercars scene.

No worries, most Lego motors are 12V ones, so technically they are overengineered for 9V.

Here wo go, I apologize if some questions might be similar to ones already asked. 1. Regarding the new CV joints: Why did you decide for a reinforced CV joint instead up updating the currently weak universal joints? Why did you got for only 2 grooves and 2 pins? Having multiple grooves and pins would help spread out the torque more evenly and reduce the wear and tear. Since the new CV joints allow for a higher torque transfer and higher transfer angles are there plans for an updated ungeared hub? Why does this and the previous version of the female CV joint part have half a stud of unusable crosshole section on the axle? 2. Regarding the linear clutch: How did you decide on the amount of the torque required to carry/slip? Was the element and this value developed exclusively for a certain set or was there a general value chosen? Did you test how does the prolong usage affect the slippage torque - does the ability to transfer torque fall after prolong slippage? 3. Regarding the shock absorbers: Was the shock absorbers overdesigned so it could eventually support harder springs? Why wasn't the deisgn modified to have mounting holes inline, thereby reducing side bending of the shock absorber? (very visible with hard shock absorbers from the Unimog) Why did you decide not to allow the end of the shock to freely rotate? This would allow easier integration in more complex suspension systems and live axles.

Indeed and I think having it in an other colors would make things like butterfly doors on yellow cars much easier.

Very organic design, well done. TBH I am mostly impressed with the front calipers, great solution.

I would NOT recommend stacking BW motors to one port due to the amount of current going through them. I would suggest using one BW motor per port. And the new PU motors are much faster and more precise than the old servo.

Agreed, the steering should have a dedicated motor which does only that with minimum amount of gears as possible. That will not happen IMO. The sliding geraboxes are very unreliable, need to spin to engage leading to grinding and jams and the gears can eventually slide on the axle locking up the whole thing. If you want to use several functions with steering and drive with one hub the answer is really simple: 1 motor dedicated to steering 1 motor for drive 1 motor for auxilary drive 1 motor to switch the auxilary drive up to 4 seperate functions with a wave shifter or 1 motor dedicated to steering 1 motor for drive 1 motor for shifting drive gears (up to 4) 1 motor for auxilary function or 1 motor dedicated to steering 1 motor for drive 1 motor for shifting drive gears AND auxilary functions, you can have one wave shifter switch low/high drive gears and AUX 1/2 1 motor for auxilary function

Tire size literally stated on the photos...

Only with single-headed printers, sorry.

Depends on how well you manage to splice them together.

You can 3D print them if you ahve a printer with multiple extrusion heads.

I managed to finish the motorcycle over the weekend. In the end I opted for a mostly orange and black combination with a gray swing arm. I think it looks quite sick, especially that thick rear wheel: The panels over the V6 engine can be opened to reveal it in it's full glory: And i took extra care in putting some detailed gauges and details such as winglets in the front: The bottom is made flat with lots of small panels used for aerodynamics along with a mother of all diffusers in the rear section: Compared to the 42107 it's much thinner (average width of 9 studs), longer (44 cm) and uses more pieces, around 770. I will post a video with even more detailed photos soon.

I see more than two parts Which are exatcly parts in question? Shock absorbers or the new CV joints or the new linear clutch?

Yes, otherwise you couldn't use them as a servo motor. Yes, of course, that's one of the main points of the entire product.

Very smooth bodywork indeed. The new parts from the Ferrari sure help ease building supercars both in 1:10 and 1:8 scale.

Very nice, clean build. You wrote you are powering the wheels directly from motors. Which motors are using for driving?

The 5L beam is not on the same level as the hub, it also travels up and down, hence it will be dragging the connector up and down the axle.

This is meant to fix the hub from moving? It will not work because the 5L beam also moves up and down relative th the hub.

The whining is the current protection kicking in. Also your gearing is all over the place, you are gearing up from the motor and gearing down at the hubs. Just build as it in the instructions and it should work okay.
