Here is my version of my Lego setup : Also a video of the up and down desk : https://www.instagram.com/reel/DVZF-GDjHdG/?utm_source=ig_web_copy_link&igsh=MzRlODBiNWFlZA==

Thank you for the detailed and very kind feedback, I really appreciate it :) I agree with you regarding the lime version and I’m happy to try a render using the P1-style mudguard layout, with the higher ones at the rear and the standard ones at the front. But it not really simple : I do have some reservations: finding a configuration that works cleanly from a mounting and geometry standpoint is quite challenging, especially when trying to keep same BOM between the lime version and the LBO version. But it’s definitely worth exploring, and I’ll see what’s realistically achievable.

Thank you very much, I really appreciate it. I’m glad the details like the air jacks, anti-roll bars and drivetrain stood out. Your feedback means a lot :) Thank you very much! Thank you very much! I’m glad you enjoyed the chassis and the presentation. The lime green version was designed with proportions in mind, so I’m happy that detail came through. Thanks for taking the time to comment. Thank you !

Thank you ! You mean about the design of the real car ? Thank you ! A ton of work on both ! Thank you for the post on your blog !

Hi everyone! Happy New Year 2026 to all of you! It’s been a while, hasn’t it? To kick off this new year, I’d like to present my latest creation, inspired by a slightly crazy project started by a guy in his garage. A project from someone who first built a GT40 replica from scratch, then took on the wild challenge of designing and building his own hypercar. I’m of course talking about the Hyperpilote by Benjamin Workshop a very famous home made French builder. I’ll let you check out his YouTube channel—he’s quite active and regularly shares updates on the progress of his project: https://youtube.com/@benjaminworkshop?si=HpPa3anAV1SEwS1X On my side, I started designing the LEGO model toward the end of his Kickstarter campaign in 2022 and completed it at the end of 2025. Initially, the real car was meant to be fully electric, before switching to an internal combustion version in 2024. This major change ultimately didn’t have a significant impact on my development, which I was carrying out in parallel, as I had quickly decided to focus my efforts early on the exterior design, using the body panels from the Lamborghini Sián 42115. Here we go—time for the photos! I. General Specifications 6-speed gearbox + Neutral + Reverse by @Anto (https://rebrickable.com/mocs/MOC-171508 ... s/#details) Gear indicator Steering-wheel-mounted paddle shifters Independent suspension Elytre doors opening mechanism Integrated lifting rams (“Air Jacks”) Front and rear anti-roll bars Self-locking differential mechanism when steering Functional front radiator Opening features: doors, hood, and trunk II. Design The design of the real car is heavily inspired by the McLaren P1. This influence is evident, on the one hand, in the unique three-seat cockpit layout, and on the other hand, in the teardrop-shaped canopy, which gives the rear wheelbase a much more pronounced and muscular stance.I reused the P1 body panels in light bluish orange to achieve this overall look. The front end is a blend of panel placements inspired by @Charbel Charbel’s McLaren 720S (https://www.eurobricks.com/forum/index.php?/forums/topic/172734-moc-18-mclaren-720s-w-instructions/&tab=comments#comment-3134415), used to shape and frame the headlight line. The headlights themselves are made from DBG barrel elements, similar to those used on the LaFerrari MOC by @T Lego: https://www.eurobricks.com/forum/index.php?/forums/topic/193303-moc-ferrari-laferrari-18/ As a small nod, I tucked a nitrous bottle behind the driver’s seat, in the spirit of Need for Speed II—for those who remember… The rising beltline between the front and rear wheel arches was quite challenging to resolve. The slope is very subtle and integrates into an opening body panel. I wanted the door opening mechanism, inspired by the Ferrari Daytona SP3 42143, to be completely hidden within the overall design. Each door opens independently via a push-button that actuates a linkage system with friction and an over-center mechanism, allowing the door to remain open. The door is then closed by pushing it back and breaking the over-center point. The door can also be opened without using the push-button; however, the lever must then be engaged to lock the door in the raised position. For added realism, I wanted to incorporate a realistic version of Nissan’s famous twin-turbo V6, the VR38DETT, complete with the full exhaust plumbing as well as its two side-mounted turbochargers. Its red engine cover contrasts nicely with the car’s orange bodywork, in my opinion. The chassis is extremely rigid despite the absence of a central spine, thanks to the 3×19 frames on each side: https://www.bricklink.com/v2/catalog/catalogitem.page?P=67491#T=C The gearbox located behind the cockpit also plays a structural role. For reference, the car weighs over 2.5 kg. And the French touch ! You want the same in Green ? Wait... III. Features To explain all the features of the model, let’s start with the schematic below: Blue: Main transmission, RWD, and radiator rotation Light Green: Gear-shifting mechanism and indicator Yellow: Anti-roll bars Red: Steering via HOG or wheel and coupling to the differential lock mechanism Green: Elytre door lifting mechanism Blue: The gearbox is based on Anto’s version: https://rebrickable.com/mocs/MOC-171508/Anto/ultimate-6nr-gearbox-with-forks/#details Go check it out—his system is brilliant! It’s a 6-speed + Neutral + Reverse gearbox. The gear indicator is visible through the rear hood (I simply forgot to add the sticker for the photos ^^). I also extended a driveshaft to operate the radiator fans at the front of the car. Light Green: The paddle-shifting mechanism is angled and uses the rotation of Wheel 2474: https://www.bricklink.com/v2/catalog/catalogitem.page?P=2474&idColor=3#T=C&C=3 A rotation stop is also included to prevent infinite spinning. Yellow: The car features anti-roll bars on both axles. Red: I designed a differential lock system that engages when the wheels are straight. During steering, whether left or right, the system automatically releases the differential. This solution combines efficiency with simplicity of use. Green: Each elytre door opens independently via a lever that actuates a linkage system with friction and an over-center mechanism, keeping the door open. Finally, not shown on the schematic, this model version features a pneumatic circuit that powers four actuators—one at each axle—allowing the car to be lifted a few centimeters off the ground. The effect is impressive when the car rises! The system is powered from the rear via a manual pump, and the selection lever is cleverly hidden beneath the horizontal suspension elements. IV.

Most of these are simple connectors, and it’s unfortunate that LEGO doesn’t offer a wider range of parts when releasing a flagship set. I do not encourage the use of third-party shops, but if you plan to rebuild this car, be aware that you may need to source parts from suppliers like Webricks or Godbricks to complete the inventory. Unfortunately, Rebrickable does not allow the publication of instructions containing non-LEGO parts, but the instructions do exist—so if you prefer the orange version, please contact me privately or via Rebrickable/Instagram. The car also features 3D-printed wheels and custom stickers. I personally designed these pieces, matching the wheel diameters of the Sian 42115 but with the design of the P1 42172. These files are included with the instructions, as are the stickers. Here’s a preview of the instruction manual’s table of contents. The design is fully modular to make assembling the car as easy as possible: 360° video : Thank you for your attention and see you !

Hello everyone, I'm pleased to present a new version of my RISE motor: it differs from the previous one in that it doesn't have a power up motor on the support foot. With this version, I wanted to operate the internal mechanics via the extraction cone at the rear of the motor. This makes it easier to vary the speed of rotation of the various compressors while playing with the variation in incidence of the blades. The inventory has been simplified and some minor design and assembly corrections have been made, such as reversing the angle of the low-pressure turbine at the rear of the engine (convergent to divergent). I hope you will like this new version, the building instructions are available on Rebrickable : https://rebrickable.com/mocs/MOC-198495/Levihathan/cfm-rise-engine-manual-version/#details You can also support the project on LEGO IDEAS : https://ideas.lego.com/projects/077efa86-88a4-43d0-930f-c6486d529361 See you !

Hello, I've reached the 200 votes on Lego Ideas ! For this occasion and because I like this kind of stuff, I've made an BluePrint for the RISE engine : You always can support the project here : https://ideas.lego.com/projects/077efa86-88a4-43d0-930f-c6486d529361

Thank you !

Hello guys ! I'm trying Lego Ideas adventure ! If you want to support this project, you can make it following this link : https://ideas.lego.com/s/p:077efa8688a443d0930fc6486d529361 Thank you in advance !

Hello, I have made a animated gif to understand the mechanism : To put it simply: the turquoise carriage is moved backwards by the white rods. As it moves backwards, the carriage tilts the green and coral blades, which are mounted on an cam. Finally, the green parts rotate, linked by a 12/20t angle gear. The entire mechanism is returned to its initial position by 2 springs (not shown).

Thanks for your comment, I hope you'll enjoy building according to the instructions! That's the whole point of a demonstrator: to be disruptive! Beyond the design, the fuels with which the engine is compatible also give hope. Yes! you can find it here : https://rebrickable.com/mocs/MOC-133571/Levihathan/cfm-leap-engine/#details Regards !

Thank you very much !

Thank for your comments guys ! Glad to hear you enjoyed the model !

Hello everyone, I'm pleased to present my latest personal creation: the CFM Group's RISE engine! This is a turboprop engine program known as Open Fan, i.e. without a nacelle enclosing the main fan. This kind of prototype, still at the demonstrator stage, should equip future aircraft by 2025-2030, if promises of reduced fuel consumption are kept! (https://www.cfmaeroengines.com/wp-content/uploads/2021/07/CFM_RISE_Whitepaper_Media.pdf) Like my version of the LEAP 1C already built in 2021 (https://www.flickr.com/photos/147164115@N07/albums/72157718957968196/with/51653430599/), I wanted to propose a standing model version once again with functional and motorized elements. I started the design at the end of 2023 and spread it out over 7 months. The final model is made up of around 1,300 parts, measuring around 20cm in diameter and 30cm in length. The big technical challenge lay in the mechanism for varying the incidence of the main rotating and fixed blades in a single movement, using a lever concealed in the base of the support! Let's see the photos: Technically speaking, to fully understand the concept, we need to distinguish between the "rotating" front fan blades and the "fixed" rear blades. A central mobile made up of 2 cradles is guided in translation by a linkage system. In transit, this mobile tilts all the eccentrically-mounted blades. The trick thing about this mechanism is that, from a single translation movement of the mobile, the front blades turn anti-clockwise, while the rear ones turn clockwise. You'll see, it's easier to understand on video! Of course, the entire mechanism operates when the motor is rotating. In addition to the technical challenge of packing this mechanism into a small footprint, I didn't neglect the aesthetic aspect of the motor to make it recognizable. Some will notice the painted parts on the blades and the nose. For the cylindrical part, which is always tricky to render in Lego, the motor is made up of 1 10-sided barrel using this assembly technique: https: //brick.camp/en/tech/clip-handle-swivel-decagon. In the compressor section, the rotating skirt is also inverted to fit under the conical cowling. Thank you for your reading, I hope you enjoyed it !
