I second this. We haven't seen this feature in any of the modern generation (MOC) supercars because the discs were too large relative to the rims. Operated with a brake paddle in the interior which is easily accessible with the roof off. The 5 star spokes will expose the feature nicely. Maybe a way to store the roof in the frunk, like a Koenigsegg.

@thekoRngear My hypothesis would be a small defect in the plastic which led to crack propagation when driving the car around, finally causing it to shear off. I cannot remember seeing a differential broken this way; its usually the bevel gears that take a beating. Good luck replacing the diff

This will definitely be one juicy parts pack! I presume the new 3x5 panel will have both a left and right version, so there is two studs of 'hollow space' in width inside. Otherwise mounting them would be quite awkward. As for the new smaller curved tapered panel, I think the one behind the doors and the rear wheels are similar. If you look closely, you can see that the angled edge does not continue further down the back of the door. I think I see another one on the inside of the inner mudguard panels as well.

Lovely build my friend! It has all the functionality you want in a 1:8 technic car of modern age and the replication of the shapes is done very well. Building a bodywork in black does hide away some of the lines, but on the other hand cluttered areas and less fluid shapes don't trigger your eyes as much - you know what I mean . The combo with the gold works really well so I think it was the right choice. All the details are spot on though the suspension could have looked more authentic IMO. Impressive how you also managed to make 3 seperate functions run trough the center tunnel - I am curious about the layout. It looks like I will have some good competition, because I have plans to build a Huayra myself next year. It will probably allow me to learn from and appreciate your solutions even more. Thank you for sharing!

Great job on this modern supercar interpretation! The bodywork and chassis are of high quality and I like the spacious cabin. There are a few areas which could be refined IMO, but admittedly these areas are always struggling points on any sports car. Keep up the good work buddy!

@Lipko Thank you for clarifying! Appologies if some of my comments about these gears were inaccurately/incorrectly described. I was under the assumption that is contact line was reduced in most helical gear designs - I am no expert in this field, I will do my research better next time. At least they still have the advantage of reduced tooth load because at any time instant more teeth are in contact at the same time. I am affraid I have mixed terms clicking and slipping/skipping. The latter obviously occurs when at high torque the gears push each other away by this radial force. I meant the application of helical gears in lego creations would be new; of course they appear in real life applications for more than a century already. Yes, although I don't know if they appear in any released sets so far. I suggest asking it in the main CaDa topic.

Yes, at the moment the helical gears are noting more than an idea I had though, but I will propose it to Martin very soon! The gears 'clicking' is caused only by the radial force on these regular/spur gears because of the angled contact line. I came across this pretty cool animation the other day which vizualizes this, as well how gear meshing generates friction. This radial force is reduced significantly in the case of the slanted teeth of helical gears, so in theory we can transfer very high torque with less bracing! I too see this revolutionize gearbox efficiency and compactness, for RC applications in particular. I might be wrong about the carbon gears though, the fibre glass mixture makes a lot more sense.

@astyanax Thanks again for the entertainment! It looks like you are getting somewhere and I am looking forward to seeing the video! I am not sure about the current CaDa parts, but I presume they are quite similar. New carbon fibre gears and axles are being developed as we speak, so soon the limits can be pushed even further! It would be cool te see helical gears in the future as well since they are ideal for high load applications. Their slanted teeth result in more gradual contact and less friction. Though they will bring some disadvantages such as axial thrust and increased gearbox assembly difficulty.

Exciting stuff! These new CaDa buggy motors make as much noise as the real car when redlining at 8000 RPM, making it seem even faster. The heavy duty differential comes in handy, becease it can handle more torque and reduces the final ratio at the wheels. The overal solution looks quite satisfying! Looking forward to seeing this develope. On the side, I was wondering the other day if the two ouputs of the buggy motors could be used in a clever way to make a compact 8 speed transmission. Basically using a 4 speed gearbox with a larger spread of gear ratios and using the 1:1.35 (approx.) ratio between the inner and outer buggy motor ouputs as increments of these speeds. This in such way that e.g. gear 1 in the 4 speed gearbox combined with the inner (faster) buggy motor output, is slower than gear 2 in the 4 speed gearbox combined with the outer (slower) buggy motor output. This can be realised for all speeds by using for instance this 4 speed gearbox by Crowkillers: https://www.youtube.com/watch?v=4bMFSqc8_cc ). In order to sequentially shift trough all speeds the buggy motor ouputs need to be switched every shift while the 4 speed gearbox shifts alternatingly, so you could say it has somewhat similar behaviour compared to a dual clutch gearbox. ...annyways, what you are working on seems like serious challenge, and my lego brain too can't resist the joy of discovering the answsers to these crazy and bold ideas!

Yes, I see what you mean. However, in such situations you ususally have a part that is serves it's application very well in a single part of the design, but in broader sense doesn't to bring a lot of potential in terms of versatality. E.g. introducing a variant of every axle lenght with stop will doesn't bring much to the table, nor will liftarms in every length. I could also come up with an infinite amount of liftarms with arbritrary amount of pin holes in any concievable shape, which beyond the use in a specific creation will not be any better suited than earlier existing parts. Obviouly there are many exceptions like the mentioned gears with new number of teeth, since this can reduce the size of many gearbox designs and make other mechanisms more efficient. Or in the context of smaller scale, I think a new type of suspension arm with socket could be very useful but then again it's exaggerative to add five new ones in different sizes. We are talking about CaDa producing these parts, which would be appearing in master sets mostly. You will not find any colour vomit in most of the existing and upcomming sets because most MOC desigers simply prefer a monotonously coloured chassis. Axles are usually more hidden and don't affect the appearance as much so it's not the same story. Yes, you can simply count holes in a liftarm or put a 1:1 scale picture on every single page and grab the correct size after a small number of trails but this simply isn't practical or contributing to a satisfying building process - agree to disagree.

@howitzer Exactly! There is no point in manufacturing so many variations of existing parts from a financial standpoint. One could also wonder if these parts would actually improve models in a signifant way. You simply have to be more creative with a limited selection of parts and as a designer myself, I do frequently run into situtuations where I think ''this non-existing part would be perfect for the job'', but after some tinkering and rebuilding in the 'existing parts domain' you usually end up with something of comparable quality. Of course most of the mentioned parts would be great, however I wouldn't be a big fan if liftarms of even length would be introduced, because people would no longer be able to easily distinguish the different lengths when building a set.

A promising start to an ambitious project! The suspension looks great and seems to work well, although I whish to see the shock absorbers on the front axle closer together, similar to the rear axle. I hope it's one of the aspects why you are not yet considereing it to be the ''100% perfect solution''. Great job on the gearbox too! I am concerned about it's size and the concequences for the interior. I am curious too see if you can compact it down by a few studs. I'd reccomend checking out some other gearbox designs, e.g. Anto's 'ultra compact gearbox' which includes neutral and reverse and saves you the effort of squeezing in an external DNR switch. Good luck!

Very happy to see this topic added to the forum! I think we all will have great fun discussing the (upcomming) master releases and growing parts catalogue with many unique parts. Proudly being part of their group of individual designers and therefore having some inside knowledge, I am afraid this topic will get unclear soon with such variety of things being discussed. However I fully understand and respect the decision to keep it to a single topic only - it's a Lego forum after all. Have a great time everyone!

Jeroen, It's been a great pleasure to watch this unique build develop with all it's complexities! It's instantly recognizable with so many clever solutions to achieve resembling body shapes. I especially love the brutal back end and the panneled underside. It let me to think it would be fun to put this in a windtunnel and see if a low pressure area would actually be created at the bottom, though presumably the airflow get's disturbed by all bumps and holes (it's a technic build after all) resulting in vortices. Some critics from me too: I don't think using mudguard panels at the front was a good idea. They throw off the proportions a bit on this part, making the front look too bulky. Moreover you can see the challenge too make the body work flow nicely towards these panels. As other have mentioned, the frunk looks a bit on the cluttered side due to the connectors. As for the front edge, I think a continuous line using e.g. a soft axle would have looked better than these #21/22 panels. Have you considered using this part as a-pillars? You can get the desired curvature whilst keeping the looks clean. Thanks for sharing!

I predict it will be either a relatively new model of Ferrari or Mclaren, two famous exotic car brands with existing licenses. Personally, Honestly I don't really care what it will be, I'll be happy as long as it will give us wide range of new (coloured) parts. The model itself will be undoubtedly very recognizable and well built, with a rainbow coulered chassis and compromised interior.

@DBurke I am sorry but right now I can't. Hopefully sometime next year.

@SNIPE That algorithm sounds truely interesting! I am curious how effectively you can make it work. Theoretically a computer should be able to better job at it than the designer however I suppose there are a bunch of design parameters unsuited to define in a code as well. Anyway there is a ton to improve on this model so I am optimistic, keep us updated!

@astyanax Using a chain shouldn't affect the performance much in this setup. The main disadvantage though is that it will be a pain to synchronize the two 16t gears - both needing the same orientation. It's an aspect a designer should consider too if it's to be built by a large amount of (unexperienced) people. Therefore using the cluch gear is undoubtedly the best solution. Unfortunately Lego doensn't produce knob gears with pinhole which would be optimal. Eventhough the axle is ineed not constraint from sliding out and as a result interfering with the differential, it won't be an issue in practice because no forces will be exerted in that direction and friction keeps it in place just fine.

Great to see another WIP topic from you! It's trivial that with this particular car the final model will be compromised to a larger degree that normal. That doesn't mean we can't expect a masterpiece as usual in the end, but this model will require to push your creativity to new levels, so I am very excited to see what solutions you will come up with! One thing I've noticed before: the 1:8 Lego rims are too wide for the front wheels, resulting in much bulkier wheel houses on the Lego version. Perhabs this could be minimized by using virtual pivot steering, but that together with all the space limitations of this model will be virtually impossible I suppose. Inspiration: I presume you will generate pretty much all of the longitudinal stiffness from the sides of the monocoque (?). There is space for a single beam running between the seats but this won't be enough of course. Have you thought about the placement of the gearbox? It may be necessary to design a new kind of lay out in order to place it higher in the car (without moving the v12), to keep the ducts underneath spacious. Looking forward seeing this evolve, good luck!

I really like building modular. For me, it first started as an experiment and challenge to put myself to when designing my Centenario and I ended up mainly with positive feelings. As a sum up of what already has been mentioned: it's convenient during the design process when endlessly revising and improving the model everywhere, it makes the assembly more interesting and satisfying (IMO) and making building instructions becomes naturally an easier task as well. Moreover it can perhabs become a bit bornig if you are constantly adding a few parts onto a larger build for page after page in comparison to building around a dozon individual components and 'bolting' them together with some pins and axles with stops. There are also builds out there who have a detachable bodywork as a single piece which is a completely different topic. It would be insane to have the intire bodywork of a supercar detached in matter of seconds, but I feel like that this inevitibly will compromise the bodywork itself to quite some extend. It seems more appropriate to do this on squarish vehicles as we've seen in Sheepo's Landrover. in other words, vehicles that don't require a complex network of panel mountings. Of course, modularity is by no means a necessity for a 'good' build, but it can really add something to the overal product on the condition that it doesn't noticably compromise the build. Doing this however, indeed requires some extra skill and a lot of extra effort. I found the result rewarding which is why I will continue to feature it in my future mocs.

Congrats on finishing this model! I have enjoyed the WIP topic a lot and I am glad to see it finished finally The overal looks are great, the rear definitely is my favorite part, despite the many pinholes from the connectors which looks a bit disturbing IMO. I have to nitpick the A-pillars too: the 9L link and soft axle are very far appart which looks a bit odd. Was this compromise made to keep the links attached to the monocoque module? Nevertheless, It's an awesome and innovative design and I will definitely dive into the instructions to study some of the mechanisms and buildingtechniques. Thanks for sharing!

Awesome work here! I love the simplicity and efficiency of the design. Little part usage and yet all necessary functions and details are present

@astyanax Thanks a lot for sharing your modification here! I love the result very much! Building it in lime has created a lot of challenges as one can witness, such as absence of the bionicle wings which naturally compromises the area around the side intakes. However, the final result is very impressive and I will definitely apply some of the changes in my model which is covered in about a meter dust. Appreciate the extensive photoshoot too, if I had known you live in Lugano (?) I could have dropped by to check it out in person as I was there for a couple of days this summer. Keep us updated on the skirts!

@amorti First I think for us hobbyist the main priority is having fun with our bricks and the amounts of views, likes and comments is not something to loose sleep over IMO. Of course it can add a lot joy to the sharing part of the hobby. In fact I can confirm myself that publishing something that goes viral is highly satisfying and does motivate me to greater efforts for my future MOCs. Like I said however, it’s more important to build something you really want/need rather than what others enthusiasts would like to see. The 1:8 scaled technic cars and B models of technic and creator expert sets are the most popular amongst the rebrickable users and obviously your published MOC does not fall into that category and therefore the statistics can not be compared. Moreover it requires a great ''wow factor'' and your submitted motorcycle probably won’t trigger that effect on most people, even though it’s a fantastic creation. After that, the quality of the presentation and details such as the price don’t really matter. Of course one must take decent pictures and write a clear description but it’s hard to mess this up. I hope this answers your questions.

Congrats on this replica! Great looks and functionality - well done! My only complaint would be the use of rigid hoses but I can see why you've chosen them. Too bad someone has stolen the spirit of extacy on your car
