  1. I have finally got around to announcing my 40th Anniversary of Technic build! I am going to be making my first fully manual model in honor of the early Technic models. I am planning to build a 2017 Ariel Nomad Tactical, which is essentially a supercharged, street-legal sand-rail/Group B racer hybrid. The Real Thing: Ariel Nomad Ariel Nomad As you can see, it is a pretty awesome vehicle. It can do 0-60mph in 3.4 seconds, 0-100mph in 8.4 seconds, and it has a top speed of 125mph. It is rear-wheel drive only with a 6+R manual transmission, chain-driven by an inline 4-cylinder 2.4L K24 Honda i-VTEC engine, transversely mounted over the rear axle which produces 235bph (which can be upped with an optional supercharger) and 300lb-ft of torque. It is built for off-roading, as it has long-travel, unequal length, double-wishbone suspension, with Bilstein shocks, and approach/departure angles of 71 and 82 degrees respectively. To top all that off, it comes in whatever color you want it to. And the whole thing weighs less than 1500lb. Who wouldn't want one?! For more info, including all the options and still more specs, check out the manufacturer's page. The Model: I am planning on a manual model with a 6-speed transmission, HoG steering, full suspension, and hopefully a fake engine. And maybe in the future... An RC version with buggy motors! Some blueprints I am using for this model. Ariel Nomad Blueprints Progress: Mostly in the theoretical stages right now, but I have started tinkering with the suspension and gearbox, which are the more crucial elements. Update coming tomorrow or Sunday.
  2. Hello, I present here a small agricultural tractor. The origin of this model is simple. It has an educational value. I used the subject to begin explaining to my son the basic principles to achieve his own models. The purpose was therefore to explain to him the following principles: - Steering rack, steering wheel. - How does a pendular axle work? - The U-joint how does it work? - Differential utility, - Realization of a simple transmission, - How to properly cross a transmission axle and a steering shaft, - What is a gearbox? ; simplified application in on / off mode for a function. There were finaly lots off things to explain. And the result is a nice tractor, playable simple to build. Here it is : About the design, we are on a MF235 base or something like that, (it's not really important;) Some other views: The rear linkage is three-point type, the PTO is in the central position, offset from the wheel axle for realizing a transmission axle with the gearbox wich is located under the steering wheel and allows to put the PTO on/off. Closer: The lifting is carried out by means of a simple mini-cylinder controlled by a crank located on the left side of the tractor: The hood is openable, of course, and we have a small engine L3 in direct drive on the differential of the rear wheels: We added some details, such as a pseudo oil gauge: Small zoom on the PTO control, under the steering wheel: The front axle is pendular (thank you to the neighbor who showed it in real life to my son), a view of the driving position, with the high exhaust pipe , in order to not 'Gaz' the farmer :) And finally the traditional view from below or we somewhat sacrificed the possibilities of crossing by installing the mini-actuator, but ...Who cares? In the end this Moc comes back to me rather well, it fulfilled its first role;) What else? Steph.
  3. RC Trabant 601

    This is a MOC. It is built in scale 1:10. Features: Front wheel drive (L motor) Steering (servo motor) 4 speed sequential gearbox (M motor for changing gears) All wheel working drum brakes (1 M motor for front and 1 for rear wheels) Full independent suspension Openable doors, bonet and trunk (which hides the small battery box) Video: Note that the car is very small (only 35 cm long) so it was quite hard to put all these functions inside. Also recognize in the video that I had to use a special solution with mounting of the differential - because of small scale. The normal solution would be too wide.
  4. RC Dodge Challenger SXT

    This is a MOC (my own creation). It is built in scale 1:10. I started this project one year ago and I wanted to make it as realistic as possible. The most complex part of this MOC is the 5+R sequential gearbox. It had to fit in very small space, so I had to use a new mechanism. It is driven by 4 motors: RC motor for drive, PF servo motor for steering, L motor for gearbox and M motor for lights. It has also realistic full independent suspension (I tried to replicate the real one) and doors with lock. Not like many lego cars, this has full interior with 5 seats. The front seats can move. The gearbox, steering motor, drive motor and two IR receivers are located above the front axle. The L motor for changing speeds is under the seats and the battery box is behind the rear axle. Video: Visit my youtube channel to see more of my creations!
  5. Hi guys! At least I has finished my next MOC and want to introduced the finished model to all of you! Welcome my International Lonestar truck! It's dimensions are: - Lengh: 101 stud or 80 cm - Width: 31 studs or 25 cm without mirrors - High: 37 studs or 30 cm excluding antennas and exhaust pipes. It consists of more than 5000 Lego parts, including 9 motors. It has: - Great Charbel's 8 speed gearbox, modified by me to the 16 speed one by adding high/low gear to the main output. It has a special shifter. It's all RC. - Independant powerfull pneumatic brakes on each wheel. Inspired by Sheepo's Peterbilt. - Pneumatically controlled fifth wheel. - Independant suspencion on front and dependant one on the rear axles. - Suspended driver's and passenger's seats, doors with locks and shock absorbers. - Detalized interior. - Inline 6 cylinder engine like the real truck. Power functions is described at the picture below, I think this is more interesting than just to read. Also I include pneumatics sheme. Enjoy the pictures please, I hope some video will apear nowadays. Unfortunately, rear differentials can't cope with such a huge torgue and truck cant drive fast on the floor, sorry. Please visit my Bricksafe page for more photo. Building instructions are available here: https://rebrickable.com/mocs/MOC-9788/OleJka/international-lonestar-truck/#comments VIDEO AVAILABLE NOW!!
  6. Hi everyone, This will be my first project in a while, and my first project here. I want to try and make a 2WD (hopefully FWD, but RWD is fine if things get difficult), 4-cylinder car with a transversely mounted engine and gearbox assembly, and hopefully as a studless construction. I started mocking-up some of the gearbox in LDD (I know, not the best tool), and the results have not been too encouraging (space-wise). I haven't yet figured how to post photos, but I will when I do
  7. Here I present my Lego Technic Airport Refueler. Yet another airport vehicle. I wanted to build a truck with a remote controlled gear box, changing gear using a Servo motor, all wheel drive and with suspension on every axle. I started with the gearbox setup from Didumos69 used in his beautiful Rugged supercar. Ideal for use with a servo motor to change gear. But I had problems shifting down gear and slipping gears when driving. My biggest concern was the amount of space the gear box needed. The distance between the axles was to large. (I wanted to build a tractor truck and not just a big truck). After a few attempts, using other examples found on the internet, I finished with a ordinary, simple inline 3 speed gear box. I had to rebuild it several times because of slipping gears….. not robust/strong enough. Shifting gear only works well during drive. Sometimes the middle gear jams causing a bad shift of gears. Finally the distance between the axles was still big, but that gave me the idea to make my truck an airport refueler truck, seen on the airport. On top of the gearbox I could place a platform lift and on top the rear axle the 5th wheel for coupling a trailer. I hardy had bricks to build the trailer, I did not want to dismantle my Mercedes Arocs (or other vehicles) because both trucks have the same scale. Therefor I used I 125 [mm] tube to create the tank on my trailer, it also saved weight. The axles of truck and trailer have suspension. Coupling the trailer is done manually. The 4x4 truck functions are controlled by the SBrick from Vengit. SBrick: 1 Drive: 2 XL motor Platform lift: 1 L motor Steering: 1 Servo motor Shifting gear: 1 Servo motor (3 different speeds). Size: Length: 110 studs - 860 [mm] Width: 21 studs - 165 [mm] Height: 28 studs - 260 [mm] platform down (about 14 studs higher with the platform lifted) Here is movie of my Refueler, hope you like it. Click here you can find more pictures.
  8. Current status: 8+N+R gearbox, D-N-R shifter, and the engine done. Also some color matchings and a little bit of interior --------------------------------------------------------------------------------------------------------------------------------------------------------- Hello, everyone. Today, I would like to introduce my new moc in progress (and the first to post here). It's Mercedes AMG GT R. (in 1:8, with porsche wheels&Tires) (From https://www.autoevolution.com/news/black-mercedes-amg-gt-r-does-insane-nurburgring-passes-110677.html) I'm planning to make it in black, as 3x11 curved black panels are available now. If amg gtr convertible model comes out, I want to try the convertible mechanism, too. My current status is only up to the drivetrain (engine&gearbox) And this is it. It's a 8 speed gearbox, with D-N-R which I built by myself. At first, I was goint to use charbel's 8 speed gearbox, which is awesome, but soon found out that the gear ratios aren't realistic (the last gear is 45 times faster than the first gear.) This gearbox is also combination of a common 4 speed gearbox and 2 speed gearbox, but different in the fact that the 2 speed gearbox is shifted every 90 degrees, and the 4speed gearbox is shifted every 180 degrees. And that resulted in a realitic gear ratio... in which the last gear is 6.25 times faster than the first gear. The hardest part was the mechanism to make one shift in the 4 speed gearbox while the paddel shift (which is not built yet) is shifted twice. The mechanism is here: Here's the sifting video: Under the chassis, you can see the D-N-R selector, which the gearstick to shift it is not built yet. As I only have times on Sunday afternoons, the progress will be very slow, but I will finish it sometime, so don't be angry even if the progress is slow. Comments are welcome, and advices are also welcome. Thanks. Oh, I missed some explanations on the gearbox. The 4 speed gearbox is just the regular one, with 1:1 to 1:5, and the 2 speed gearbox is 1:1 to 1:1.25 which doesn't work yet as currently I don't have any chains. The chains are also linked to reverse gear.
  9. It's a monster truck with a 4x4 trasmission and 2 speed gearbox powered by a SBrick. This MOC is very powerful because the first gear generates a great gear ratio. The chassis is simply and very strong and the suspensions are attacked to him. I couldn't use the "large hard shock absorbers" because i haven't them, so i used the "small soft shock absorbers". I added a V6 working motor, a rear openig hatch, and lights too! These pictures above are of the old version, in fact the axles and the position of the SBrick in the images are different from the current ones (below). The differential is removable to ensure more traction. The gearbox is very compact and strong (on that I worked a lot of time). The green axle is the input, while the red one is the output: the yellow gears are interested for the first gear and the blue ones for the second gear. The first gear has a gear ratio of 5:1 (very powerful), while the second gear has a gear ratio of 3.3:1 (balanced). The gear ratios were calculated by adding the gear ratio of the all transmission system, ie 3.3. And this is the outdoor video! I hope you enjoy my MOC! Leave a comment and a Like! ;)
  10. Hi everybody. As I was into the shop this midday I saw this set: This makes me think, even if it is a star wars figure, that this pretty girl needs a bike. A BIG bike...just like Lara Croft.... So I decided to build something different this time. And here is the result of this evening build: it is the first sketch of what the model will be, as usual. About everything is to be compacted and redesign, but this give a good idea of what is incoming. Tomorrow I will by the SW figure st to match the scale of both of them. All the ergonomic aspect of the bike will be calibrate based on the TLC figure I let my imagination do this evening, Motoguzzi inspiration mixed with old BMW/Harley frame....All is in the mix. I am pretty happy with what I came out. This give me the base and a vision for the next of the build: The main ideas are: A fully detailed enormous engine fitted into a lightweight frame and all terrain wheels. At this point I do not have any idea if I will realize back suspension or not for this model. maybe just a suspension for the Saddle ? It will have a gearbox, already sketched and installed. The sequential lever is still a question actually. I think to due to it's size, it must be realized here. I do think that this model will take me a lot of time to finished. It is a quiet unusual theme for me. But I like the challenge that it represent for me. Any comment or advice are welcome. To be continued...
  11. First of all, I'm completetly new here and my english isn't perfect. In the future I will start building an LPE powered car that is inspired by nicjasno and his E30. I'm not sure if I will model an existing car or create a new one, but it will be around the same size of his car. The gearbox is one thing that I just can't get over. I don't even care about how many gears it has, I mainly need reverse, because that is the only way of going backwards with an LPE car. It has to be RC controlled of course, which is easy to implement in a 1+r, but harder with more gears. The most important thing that it has to feature - smoothness and rigidity. If it isn't compact, then that's not a big deal. It will be powered by an Inline 4 LPE which revs up to 5000 rpm, so downgearing is needed as well. The other elements of the car aren't built right now because of the lacking parts, but I want to have the blueprints of the main elements of the car before I start building it. I know that I will have enough problems when I will build it, so I try to plan as much as possible before. If you have seen or have built something like this in the past, please share it with me!
  12. Over the past couple of months, I have very much enjoyed many of the build threads that have taken place on Eurobricks. Of note was the excellent Hammerhead thread by @Didumos69 where the build kept improving in no small part because of the feedback given by so many. In this same vein, I wanted to embark on a less ambitious project. I'll try to update as often as I can. The project is a manual sports sedan in mid-scale. Features (at this point, in order of priority): Four wheel independent suspension Rear Wheel Drive Steering (Steering Wheel, HOG) Four Doors Flat 6 Opening Bonnet Opening Trunk Toddler Safe Transmission Current Progress Basically, the dimensions are set, and the suspension will not change much. Now I'm working on a transmission, which I have not decided if it will include. A manual gearbox puts the shifter a little too high for the scale, and this sequential will fit, but the changeover location is not great, either forward or rear. I'll update this again tonight, and see what I can figure out.
  13. Hi all, I present you my finished MOC of a 7-seater familycar with full functions: DETAILED PDF INSTRUCTIONS NOW AVAILABLE HERE, REBRICKABLE ENTRY HERE Separate PDF instructions for the roof implement available HERE, Rebrickable entry HERE I got the idea for building a family car about 3 years ago, when looking for a bigger car IRL for my own family. I was intrigued by the fancy seat folding mechanisms seen on these type of cars and wanted to reproduce that. For the model, I took inspiration from the Ford S-Max, which in my opinion combines good looks with all familycar requirements. It also comes in some fast versions, so it is fun to drive as well (unfortunately, IRL this car is well above my budget... Ah well...): It was clear to me early on that I would not be able to reproduce the exact looks (I'm not that good a scale model builder), but I wanted to stay as close to a real life car as I could in terms of mechanical features and looks on both interior and exterior. Meanwhile I wanted it to be structurally sound as well, based on modern "box structure" car frames. I built numerous iterations, starting in 1:8 scale, and later switching to 1:10 scale after having to much trouble with the larger scale when it comes to chassis stiffness. I have worked on this on and off for over 2 years, finally resulting in this build. The model has: 5+ R gearbox with linkage control: full suspension (independent McPherson with drive in front, dead trailing arm axle in the rear): 4-in-line transversally mounted fake engine in the front: rigid box structure chassis full interior with adjustable/folding seats on all rows: Folding the seats movie opening doors (with lock), boot and hood: parking brake (transmission lock) I wanted the maximum available interior space for this car (that's what a family car is all about after all...), so I set myself some goals: no supports from bottom to roof inside interior space: center console should be no wider than 5 studs: front wheel drive with front engine and gearbox: I wanted to create a rigid chassis, which would not bend and is self supporting. Because I wanted as much interior space as possible, the bottom structure is only 2-3 studs high. I couldn't fit vertical frames in there (as they are 5studs high), so in the end the roof became an active part of the structure of the chassis. It is very strong and stiff, when one wheel is lifted, there is hardly any bending in the chassis, instead the opposite wheel suspension is compressed: The whole car can be lifted safely with only one finger, from the midsection on the roof and by the B-pillars and C-pillars: Here are some more pics: For a full gallery and all WIP photo's, check my bricksafe folder. ============================ Below and further in this topic is all the WIP progress of making this car from July 1st onwards: Pic of current chassis WIP with parking break (back yellow knob), gearstick (in front of parking brake) and linkage (beneath and in front of gearstick), and start of gearbox mounting and front suspension (McPherson with drive from Sheepo's MPS)
  14. Since a little moment, I wanted to make a Citroën DS for 2 reasons: This car has a very particular design and it had an innovative mecanic It has not prevously been made in Technic. So I can be the first! ^^ I wanted to reproduce all the features: Suspension Steering with the headlights moving with the wheels Height adjustment using pneumatic (Just up/down, not intermédiary) Gearbox (not defivitive yet, see below) Openable hood, trunk and doors Perhaps the body will be detachable (like the Nico71's 2CV) And a nice design! Actually, I did the chassis. It is not finished, but almost. And it was very complicated to make, this chassis! On the real car, almost all the macanic is in the front part of he car (under the hood). The problem is that it's not really possible in Lego, furthermore I wanted a chassis' height of 3 studs. So, I put the gearbox in the back of the chassis. That is working, but it's not realistic. So can you answer this question: do you like this construction, or do you perfer that I try to put a 2 speed gearbox just under the engine? Here, you can see the headlights moving with the wheels: It's simple, but we don't see that on supercars. There is not HOG yet. I don't know if it will be the steering wheel only, or if there will be one other on the dashboard. The chassis height adjustment allows almost put it down. The suspensions are soft. They give to the car a "boat" effect. And the gearbox: It is linked to the front wheels, but not actually to the engine. I wanted a DBG body, but the parts don't exist in this colour. So, it will be white. Tell me what you think about this begining!
  15. 2Speed + park

    my first perfect gearbox! a gearbox with two speeds, and a park function. the gearbox was made for my Air Pocket supercar. i wanted a low, flat gearbox, with two speeds and park. it is designed for a second shift section to be added for more gears, but bigger size. it has a gearing function, you can adjust first gear from 5:3 to 1:3. the 24t and 8t gears are able to be swapped for a 5:3 ratio by using the 20:12 combo. instructions here. http://bricksafe.com/pages/aventador2014/2-speedpark
  16. The second of my three MOC's, the Audi TT. Again, apologies for the photo's. The TT is one of my favorite cars, and I've tried to capture the design as best I can. This one has the following features: - Full independent suspension. - 6 + N + R sequential gearbox (design by liftingbricks), driven by a porsche flappy paddles. - All wheel drive and five cylinder engine. - Opening doors, bonnet and trunk. You can see more on my Flickr IMG_20170528_140525 by Russell Murphy, on Flickr IMG_20170528_140510 by Russell Murphy, on Flickr IMG_20170528_140649 by Russell Murphy, on Flickr
  17. Hello all ! I want to present you my curent wip MOC, an old styled race car: Features will be : -suspention(checked) -HoG(checked) -steering wheel(checked) -working engine(checked) -4speed sequetial gearbox(checked) -doors(checked) -engine cover(checked) Hornestley I am building this car just to use the tumbler tires They are quite big for a chassi like this (only half a stud between chassi and them when full steering is aplied). Adding an 8 speed gearbox to this kind of a car size is quite challenging but defenatley not impossible :) Side view: Interior as of now (steering wheel by Didumos69): I hope in the end it will be strong and very playable . Any suggestions and comments are welcome :)
  18. Hi everyone, I have already posted this gearbox in the Gearbox collection thread started by Didumos69, but now that I have finished the instructions (as promised@mocbuild101, here you are :-)) I thought it would be a good occasion to start a specific thread on this gearbox. I am currently working on a MOC which has this gearbox implemented (will start a topic for that one in the near future as well), for which I had some specific requirements: I wanted manual operation on standard LEGO 5+R configuration, but with a gearstick that would pivot in all directions from a single point (like in real car). Apart from that, I wanted a center console that was not more than 5 studs wide, so the gearbox had to be moved away from the gearstick. I took my inspiration by Thirdwigg's 6speed gearbox from his Cadillac ATS supersedan, Crowkillers 4speed gearbox from his Asassin X19 and the 5+R gearbox from Nathanaël Kuipers' Predator. I ended up mixing them all with some inspiration from the 42054 Claas steering mode selector as well. Note: the version in the instructions is using the new DGB driving rings and red clutch gears, they actually give a more solid build (when I shot below pic and vids I had already used mine in aforementioned MOC, so I converted it to the old rings and wheels. Works fine as well, just a bit less solid). Manually operated Direct operation special features: single pivot point for gearstick, linkage to gearbox, fits in 3studs wide center console number of gears: 5 forward, neutral and reverse Here's some vids (apologies for noob quality...) and the instructions: Gearbox in action Shifter linkage system in action Instructions PDF Enjoy and let me know what you think of it.
  19. This is an attempt to start collecting gearbox designs in a single thread. To get started, feel free to add existing gearboxes, but please always add a reference to the original designer. Also be sure to add some information on designer motorized or manual sequential or direct special features like paddle shifters and number of gears, e.g. 5+R. That will also help me in making an index in the OP. Or even better, if it can not be classified along these lines from the entry here, I will not add it to the index. Thanks!
  20. Sequential AWD 4-speed gearbox with V8 fake engine Features - AWD with center differential - Sequential 4-speed gearbox - One-finger shifter - V8 fake engine This gearbox is an excerpt from my rugged supercar project. The mid-console has an important role in the overall stiffness of that model. It had to be narrow as well. If you build (have built) it, you will also notice it has very little torsional flex. I wanted a 4-speed sequential gearbox covering a wide range of ratios. So not something like 1:2.5 upto 1:1, but rather something like 1:3:5 upto 1:0.8. Another requirement I had, was that I didn't want red clutch gears to transfer drive on axles rotating at different RPM. This is a common practice, but from modding the Porsche I know it induces a lot of friction on the axles involved. When not engaged, red clutch gears better only make dummy rotations and not transfer drive. And finally, all had to fit underneath the engine; I didn't want the gearbox to be routed through the entire chassis. Instructions available on Rebrickable.com. Have fun!
  21. I said before in my previous post that I had some problems with my GX EV3 4x4 chassis that I needed to fix. Once again, it's more gear grinding/clicking, but this time it's only in the front and rear differential gears. The grinding occurs whenever the chassis tries to drive into a wall or when it tries to drive in different conditions (because as an SUV it should drive smoothly in dirt or uneven terrain). What also annoys me is that when I push the car, instead of letting the motors move, the differentials make clicking noises that, like I said before, sound like a machine gun. I really need help so I can stop the differentials from clicking so when the car tries to drive into the walls, the motors won't still move while the differentials click, and so the car can be a lot more versatile on uneven terrain (such as what I used for testing, blankets) without the differentials causing a problem when the car moves. Here's some pictures of the bottom of the chassis.
  22. I'm back again with another gear grinding issue but this one is a bit less critical. The grinding only occurs when my 4x4 SUV chassis (with Sariel's 4-Speed Sequential Transmission) is in a certain gear. Here's some photos of the chassis. The transmission is shifted to the speed where the nonstop grinding occurs. When in this gear (I believe it may be 3rd) The car is supposed to move, but it does very slowly while clicking noises fire like a machine gun. This is the only time when the gears grind other than, say, if the chassis hits a wall. When the clicking begins, I hear the driving rings shake (which awfully reminds me of the somewhat gear clicking in the Mercedes-Benz Arocs set). I would love a response a soon as possible to address the clicking problem so I can finish the chassis once and for all.
  23. This is my second post on the EuroBricks community and another question asking for as much help as I can get to master the art of the technic gearbox. Like I said in my previous post, for my Lexus GX EV3 4x4 SUV, I tried my best to use Sariel's 4-speed sequential and it ultimately failed on me. Quoting one of my replies... I would be relieved if I could finally finish this creation after five months of difficulty. Here are some pictures of the entire chassis. I said before that the issues with this was that the gears clicked a ridiculous amount at the highest gears which stopped the car from moving. (Hence the reason why the transmission I want needs to have a clutch gear to absorb the large amount of torque)
  24. Hi, I'm looking for a reliable remote controllable 5+R sequential gearbox or ideas how to build one. If it would have a neutral as well it would be perfect. Please share your ideas and if you are aware of any kind of existing solution please share the link. Thanks, Zoltan
  25. This is my latest MOC: an Ariel Atom 500 in 1:9 scale! Technically it isn't a true scale model since I didn't use exact dimensions (I just build what I think looks best), but size-wise it's about 1:9. The real car is the fastest ever variant of the Ariel Atom, a street-legal car built for track racing. Released in 2008, the Atom 500 features a 3-litre transverse-mounted V8 made from two motorbike engines. It produces 500 horsepower (hence the name) and redlines at a rather insane 10,500 RPM. Other modifications include massive wings and the gold-painted exoskeleton. The car weighs only 550kg, giving it a power:weight ratio of over 900hp/tonne (higher than anything short of a Koenigsegg) - It recorded a 0-60mph time of just 2.3 seconds and could reach 200mph. It was the fastest road-legal car around the Top Gear Test Track for over two years. That record lap was on damp tarmac - had the track been dry, it would probably still be at the top. Only 25 of these cars were made, selling for around £200,000 each. My model features: Remote control drive and steering with Power Functions - 1 XL motor for drive and 1 M motor for steering 4-speed sequential gearbox operated with paddle-shifters Working steering wheel Full independent suspension with longitundinally-mounted shock absorbers Steering has zero scrub radius V8 engine replica with moving pistons The zero-scrub radius was a new idea for me. When playing around with suspension linkages, I discovered that mounting the links in a certain way would cause all four to move when turning (rather than just the steering link). The center of steering was further outwards, almost exactly in the middle of the wheels (I think it's where the suspension links would intersect when extended, but I'm not sure of this). The geometry I chose works almost perfectly for 68.8x36 ZR tyres on 56mm rims. Here's a picture of the steering links in their two extreme positions superimposed - the point where the wheel shafts intersect is the center of steering: The suspension is standard double-wishbone in the rear, but with a sideways lever converting the upwards motion of the suspension into longitudinal movement of the shock absorber: The transverse V8 was very difficult to fit in because it has even dimensions and the rest of the chassis has odd dimensions. It is connected directly to the XL motor The interior (or as close as you can get to an interior in an Atom) features two racing-style seats, a steering wheel and paddle shifters: The aesthetics were rather difficult at times. The framwork was very difficult even with the 42055 yellow parts (in fact, getting that set is the reason why I built this model), and at times I had to use some tricks. For example, the rear framework looks like it has two beams crossing in an X-formation when in fact the left and right halves of the "X" are two separate structures: I also replicated the exhaust pipes and gigantic rear wing. One of my favourite parts of the model is the side intake and its red stripe: The PF IR receiver is disguised as the air intake and roll hoop: For more pictures of the car, see my video below. Music is composed by me as well: [media]https://www.youtube.com/watch?v=RhmgbCIpHT0[/media] This project is also on LEGO Ideas! I know the success rate is extremely low for such projects, but it would be amazing if this set because a reality! Please support my project here. Any support is much appreciated.
