[MOC] Dune Buggy RC - 8284 Redesigned
cyberdyne systems posted a topic in LEGO Technic, Mindstorms, Model Team and Scale Modeling
Good day/night/whatever everyone! I want to share with you a little experiment of mine that got a bit out of control. I hope, you remember set 8284 and its really unique looking b-model. At least I do. Furthermore, it is one of my favourite b-models and I really wanted to pay tribute to it. Obviuos thought was, of course, to make it RC with the new Control+ elements. After half an hour I got something that could drive and steer. I even tested it in the local park, but... something was off. It just wasn't enough. However good looking this buggy is, its transmission wasn't created with electromotors and speedy driving in mind. Wheels tended to fall off. Gears in diff broke at least once. And offroading capabilities were...em... on the small side of expectations. And I got an idea! I decided not just to motorize this buggy, but completely redesign, reimagine it from technical point of view, keeping exterior close enough to what it was before. You know, like these like-oldtimer-outside-but-modern-inside tribute cars which car companies sometimes make. Also I wanted to make transformation function more interesting and useful. So, I started on the blueprints... And here it is! All modern all new Dune Buggy! With familiar face which got a facelift. Literally. New version of transformation not just shortens the car, but lifts all front section up While cockpit raises up, special levers make sure that headlights between wheels always stay horizontal. And not only that. Another special lever in the rear section locks the differential using new orange shifter. This way buggy becomes most offroad. And now - to the video! (With the new intro btw) -
Lego Technic Tamiya Neo Fighter buggy (but it is 4x4)
Lixander posted a topic in LEGO Technic, Mindstorms, Model Team and Scale Modeling
Among those 3 buggy`s/ truggy`s that I have to test-build them I just managed to add a 4th one. This one is the first 4x4 with 2 motors. As usual, it packs some buggy motors (2 of them, as I said), a servo, removable body (at least semi-detachable), positive caster-angle and full independent suspension. The weight is just under 900g; pretty decent, considering it is 4x4 and that has a pretty big body and some useless pieces to imitate the electric motor of the real RC buggy. Unfortunately, I think that this will only be available with normal RC batteries, because almost no existing hub for Lego is not fitting. -
[MOC] Trial Unimog - Zetros (42129) alternate
gyenesvi posted a topic in LEGO Technic, Mindstorms, Model Team and Scale Modeling
Hi All, Although I have posted a few pictures previously, I wanted to make a proper writeup of my Trial Unimog alternate of the Zetros set (42129), because I think sharing the design process is valuable for people around here. Also, I am going to share my thoughts about the set itself as a parts pack. But for the curious ones, here's an action video of the end result and a short summary of the features: Features: - good actual outdoor performance :) - permanent AWD, no differentials - 2-speed gearbox, faster gearing than Zetros - relatively large increase in ground clearance - 4-link suspension on the back, large articulation, soft suspension - 3-link suspension with Panhard rod on the front, slightly larger and softer articulation than the Zetros - opening (and lockable) doors and trunk bed When building alternate models, I always try to build something different from the A model, both functionally and in its looks. So when considering what to build out of the Zetros, keeping the Mercedes brand but going for a different form factor, my first idea was a G-Wagon - quickly taken by Grohl himself. Then I though, let's fall back to a Jeep - also taken quickly by Tim.. Unimog was on my list of potential alternates, but I wasn't sure about it yet. But one thing was sure: I wanted to improve the actual off-road performance over the Zetros. So putting the form factor aside a bit, I started experimenting with chassis and suspension designs. One option I had in mind was to keep the live axle setup, but improve it to make it actually useful for off-roading: increase suspension travel, ground clearance and responsiveness. Furthermore, I wanted to see how lightweight the axles could be built, because the Zetros's axles are pretty bulky. I was okay with doing away with the diff-lock, since I wanted to use the M motor for a 2-speed gearbox anyway (just like others). During experimentation with axle designs and suspension travel, I have realized that the 3-link live axle setup of the Zetros is not only limited by the springs' short travel, but also by the 3rd link on the top. That link cannot rotate sideways on the chassis side and is mounted very high on the axles, and as the axle tilts, its top can move sideways significantly, and as the link cannot follow it sideways, it limits the axle's tilting movement; hence very limited articulation. The setup only works for a short range of movement as on the Zetros, which is limited anyway by the springs, but cannot work for a setup that aims for more articulation. One way out of this is to allow the 3rd link to rotate and follow the side movement of the tilting axle, but then the axle needs fixing sideways. There are two ways to fix that. Either a 4-link triangulated setup, or a 3-link setup with a Panhard rod. Although the Zetros does use a Panhard rod at the front, it is unrealistically mounted and too short, that would cause kind of bump-'steer' for larger axle articulation (not exactly bump steer, but more like shifting the whole axle sideways). So after taking the limited number of suspension parts into account (only 6 towball sockets left out of 10 since 4 must be used for mounting the front wheel hubs, and only 1 6L link available in the set), I opted for the following design: on the rear axle, I used 4 towball sockets for a 4-link triangulated setup with long links, allowing the upper links to rotate sideways and follow the movement of the axle. The springs are attached to the middle of the lower links. This allows for long upwards movement of the axle at the end of the links, and makes the suspension much softer even with the hard springs. Pretty solid and allows for large articulation, just what I wanted. Furthermore, the axle itself is quite slim and rigid, and has good ground clearance, especially in the middle where it's most needed (as proven by my off-road tests). The front axle was more challenging. First off, increasing the ground clearance is only possible with one trick: the towball socket liftarms must be built at an angle, going upwards in the middle, and that limits possibilities. Second, the steering motor and its mounting takes space on the axle, and is in the way for the suspension mounting points. I have experimented with two other options: steering through a driveshaft coming from the chassis, but the placement of the motor in the chassis was problematic do to space required by all other motors and the battery, along with the largely articulated suspension design; second I tried to put the steering motor above the front axle, actuating steering through a linkage system. Although, this worked quite well mechanically (verified with the Powered Up app), unfortunately, the Control+ app itself killed this direction: the app limits the steering motor angle to about a 25 degrees less than the calibrated range, which is normally 90 degrees or motor rotation, resulting in about 65 degrees in case of the Zetros (that's why it's steering is so bad by the way). Now in my alternative steering design, the max calibrated angle would have been 45 degrees, and the 25 degrees minus by the app resulted in about 20 degrees of movement, resulting in almost no actual steering at the axle. Pretty sad that you can build something mechanically sound and then not able to control it with the app :( So I fell back to mounting the motor on the axle, and used the remaining 2 towball sockets for two lower links, which again, I built longer to allow for a bit more articulation. Luckily, I was able to mount the motor in a way that it allowed to use the single 6L link as the 3rd link, allowing free sideways tilting movement of the axle, as it is attached to a towball pin on the chassis end as well. I also experimented with the spring mounting technique of the rear, but it was weak and wobbly on the front without the 4-link setup, so I went back to mounting the springs on the axle. However, I managed to move the springs closer to the center of the axle, resulting in both slightly larger articulation and softer suspension. Finally, the axle is fixed sideways by a long Panhard rod going from one end of the chassis to the other end of the axle, eliminating bump 'steer' quite well even at larger articulation. As a side note about parts, it would be really nice if the set had another 6L link somewhere, for example as a Panhard rod on the rear axle. It could be used to build another 4-link suspension to the front, and also as a steering link in an independent setup (which is problematic to build for other reasons as well). So after sorting out the two axles and the suspension, I though this could be used in a Unimog chassis. Though not too different in form from the Zetros, but at least it keeps the brand. Furthermore, I decided to make it different in its functions: the first step was focusing on a proper suspension. The second was the drivetrain. And that also caused some difficulties. Unimogs are short. You'd think that's not a big problem at this scale, as many RC Unimogs have been built before, but it is with the latest drivetrain parts. The new CV joint with a sliding axle hole is a whopping 8 studs long!! (Compare that to a 3L U-joint; sure, the CV joint has the axle built in on one side, but this construction limits builds quite a bit. Not sure why the new sliding variant needed to be 2 studs longer, I thought it would be just 1 longer, enough for the sliding, which is typically about half a stud, but 1 stud max). So two of those, plus, two non-sliding ones at 6 studs length, and your driveshaft is already 28 studs long. Add to that the amount of space required by the differentials (2 studs on each end until the axle center), and your axle distance cannot be less than 32 studs. Add one more to get a nice odd length middle section, and we are at 33 studs from axle to axle. It is quite long for a Unimog. (As a side note, I tried to split the driveshaft in two halves, shifted sideways in the opposite direction to let them overlap in length and hence make things shorter, but it did not work out due to the axle length limitation of the CV joint part and also space limitations from the motors). So because of this, and other considerations I decided to do away with the differentials altogether. It saves 2 studs in length. It allows for a slightly faster 12T / 20T gearing; the Zetros is just too slow. Furthermore, it allows for larger ground clearance, as the differential does not stick out from the axle. It even allows for a slimmer axle design, as there is more space in all directions, such as for mounting the steering motor. And last but not least: no differential - no need to lock them :) With unlocked differentials the off-road performance would be bad anyway. Once I settled for the length and the drivetrain, I needed to place the remaining motors and the gearbox. I was able to sandwich the gearbox between the drive motors, and put the gearbox's driveshaft motor on top, the flip-flop beams and the frames proved to be very useful for building a strong but lightweight chassis. The final challenge was the driveshaft from the gearbox motor. I am not sure why TLG used this motor here as it is super cumbersome to work with. It needs substantial down-gearing (and the right amount for your actual application, which is 180 degrees final turn for a gearbox, but 90 degrees for a diff-lock), a clutch mechanism for safety and physical end stops for calibration. These all take up space as they need to be routed somewhere. Things would have been much easier with another L motor.. (Maybe to make the set slightly cheaper? Or TLG is trying to get rid of these motors on stock? They don't seem to fit well into the PU system without positional control.) Anyway, finally the chassis of the Unimog was complete. I used the remaining CV joints to connect the drive to the spinning fan in the front :) The rest was just bodywork and placing that big hub somewhere. I opted for roughly the same position in the cab as the Zetros, but with the cables inside, to allow easy access to the batteries for replacement. For the design and styling, I took some inspiration from online sources like this one because of its color scheme, but I wanted to minimize the cab length as there weren't enough panels for a 4-door version. I built the cab with no opening hood to make it solid :) And also made the doors lockable to avoid them opening automatically when driving around.. Finally, the black panels were just the right size and amount to cleanly finish the bed, both the sides and the floor. The bed floor opens (but lockable) to see the gearbox, and to give room for accessing the batteries. I have also added fenders and the usual decoration like the rollbars, exhaust pipe, mirrors, ladders. Here are some renders of the whole build. As you can see, I did not use any green parts, as they would have only added clutter to the otherwise clean bodywork I think. Some more notes about the parts of the set apart from the ones mentioned above. The set has a good amount of paneling and beams and connectors, although the green parts are a bit less useful since they are limited in number and size. Another shortcoming of the set is the available gears. It has all sizes, but their number is lacking in some cases and hence high gearing ratios are hard to achieve. For example if you try to deviate from the default drivetrain, those gears will be missing for example for a simple down-gearing for the gearbox motor.. More images can be found on Bricksafe. Building instructions are available on Rebrickable. I did not know too much about Unimogs in the beginning, but during the research and designed process I actually came to like Unimogs quite a bit. I like that they are compact but seemingly efficient machines, and the trial versions actually look pretty cool. And I am actually quite happy with the end result. Let me know how you like it and your opinion on the set's parts! Cheers, Viktor -
[MOC] 42099+42110 Defender RC conversion (Control+)
cyberdyne systems posted a topic in LEGO Technic, Mindstorms, Model Team and Scale Modeling
Good day, everyone! This project has started as an idea of creating better a bodywork for 42099, but after some time in development it turned into undependent rc modification of Defender 42110. I took inspiration from Bowler WildCat and Bowler Nemesis which are extreme buggy-like offroaders based on Land Rover cars. So I pondered the question, What if... new Defender would be made into Bowler? In result - original defender has become lower, has got lower roof profile, bigger tires, front and rear pushbars, snorkel pipe, stronger footrests, two sets of additional lights and fog lights, antennas, front and rear mudguards, some chains ('cause chains are cool!). Engine was swapped from 6-inline to V8-supercharged! (After I made this model in spring, LR has announced that they will actually make a V8 Defender. Sadly, not supercharged :) Engine and cooling fan are connected to the front axle via chain links. (Yes, chains ARE cool. I had to buy whole Ducati set for this) And the most important - Control+ components. As this Bow-fender shares control profile with 42099, set of electrics is the same. One XL+ for each axle One L+ for steering SmartHub for SmartThings And then I found out that I am... well... not really good in making offroad chassis. At least it was my first try. So I tuned it as much as possible and made a note for future to learn more about lego offroading. (I think, I'll start with Zetros). Video of how this Bow-fender drives on everything it can is of course here: Watch till the very end! And Thanks for watching. Subscribe. P.S. This cat was walking nearby, while I was making video, so I asked him to participate. So there is A cat in the video now, instead of THE Cat - erpillar :) -

CrazyKreations posted a topic in LEGO Technic, Mindstorms, Model Team and Scale Modeling
Hey everyone, for a couple of months I've been working on a lego technic camper module that fits on Lego 42129 easily! After a lot of designing, I have come up with a design. I've made a video for all to see and please let me know what you think of this model. This model doesn't affect the Zetros's ability to move in any way (however just to be safe please consider reinforcing the rear axle). It has the following features: Awning Interior with dedicated seating area, bedding and kitchen (kitchen has to be built with bricks haha) rear compartment storage along with a lock Openable windows for ventilation Flexible but sturdy structure for offroading openable door Additional step ladder that can be used to enter the unit Additional storage on the door side of the unit that has a separate compartment to the rear storage space for jerry cans Space for extra wheel -

After my rusty train, I was wondering if I can give the same treatment to a car. I wanted to build a beetle for so long, but I don't wanna copy other's work, and also wanted to make some weird stuff, it's a kinda trademark that I have :P After Several hours of designing, I came out with this Baja Rat Rod based on a Beetle The suspension and steering are fully articulated and posable, but they won't work as real suspension/steering, considered this more like an action figure that you can do some dynamic poses to take some cool photos. Even though most of the car is gone, I tried to keep the recognizable beetle profile.

[8081 MOD/MOC] MM //COMMANDO// - Winch is ready!
johnnym posted a topic in LEGO Technic, Mindstorms, Model Team and Scale Modeling
Some might still remember this offroader I started sometime ago in 2019 and showed earlier versions in the 8081 mods thread a while ago. Well, I finally "finished" it now and created digital models for it. I call it the COMMANDO and it is "sold" by MM (Mars Motors). People that follow my Turbo Racers series and my series of 42093 scale cars with swappable engines should already know MM. To show its capabilities I made a trip to a special location and examined what it can do there. Have a look into the video to see what it possible: The configuration in this video has all axles locked and uses the drivetrain variation #2 (see below). The COMMANDO started as the glorious 8081 A model and went through lots of modifications - especially to the front and rear axles and also to the outer hull - on the way to the final result. I created three versions so far: with 1 x PF AA battery box with 2 x PF AAA battery boxes with BuWizz 2.0 ...from which the BuWizz one was used during the video and also most of the time I drove it so far. Here are a few more detailed pictures showing it in that terrain: Here are two pictures showing the chassis construction (click to magnify): ...and here are the three drivetrain variations that can be used (click to magnify) More variations are possible and the gearing can be changed with relative ease, as the motors are not an integral part of the construction: #1 is used for the PF versions and #2 is used for the BuWizz version. #3 can be used to examine the effects of open differentials in offroad situations. The COMMANDO can use various tyres and clearance should be good enough for all of them: 45982 81.6 x 38 R Balloon tyres 18450 81.6 x 44 R (Tumbler) tyres 69912 81 x 35 Tractor (Zetros) tyres I have also already designed a few addons that will be released at a later time - need to create the digital models first - and I have even more ideas for it. So far I have available: front winch rear PTO exploration gear tracks So stay tuned for additions. I hope you like the COMMANDO and I hope it is a worthy successor to the 8081 A model. If you're interested, the - free of charge - digital models (Studio files with detailed steps and submodels) and more pictures are available on Rebrickable: https://rebrickable.com/mocs/MOC-111591/johnnym/mm-commando/ -

[MOD] 'Rusty Bucket' buggy
SilenWin posted a topic in LEGO Technic, Mindstorms, Model Team and Scale Modeling
Greetings, ladies and gentlemen! I'm glad to introduce you a modification of @Didumos69 Greyhound buggy Yeah, "Mad Max" inspired vehicle again First idea was just "increase durability and add some crawler abilities", but result exceed all my expectations. Adding planetary gear reduction 4:1 to all wheels increase offroad capabilities to sky high (keeping in mind perfectly working suspension of original) And final step - I decide to prepare for summer offroad Lego event in Moscow and for future festival, so I reworked exterior in postapocalyptic style. Other photos Here is LDD model of front hub with planetary gear reduction I used in my modification. Rear hub is done similarly, except for black connectors to suspension arms and without U-joint. Bonus: video from "King of the Hammers" race event in Moscow and photo from "Summer Brick" Lego festival in Taganrog, Russia Thanks to @Didumos69 for his amazing buggy and instructions, and also to @Shurik & @VerSen for cool photos! Hope you like this rusty piece of metal! -
[MOC] Avtoros Shaman 8x8
Madoca 1977 posted a topic in LEGO Technic, Mindstorms, Model Team and Scale Modeling
Hello everyone! Since TLG released 76023, I had been waiting for affordable Technic set which includes so-called Tumbler Tires. So I jumped at 42050 Drag Racer. I also bought some extra tires separately, then revived old project which had failed three years ago. Avtoros Shaman 8x8 Building instructions: Rebrickable Weight: 2550g - 4x L motor for 8 wheel drive - 2x Servo motor for 8 wheel steering - M motor for switching steering mode (AWS and crab) - M motor for winch - 3x LED for front and rear lights - 2x SBrick powered by 2x 8878 rechargeable battery box - Independent suspension for all wheels - Working steering wheel - Openable hood, doors and roof hatch Back in 2013 As you may know, real Shaman is which can go through almost any kind of terrain. It has three steering modes and can scale 45-degree incline. On top of that it is amphibious. Seeing pictures and videos, I instantly fell in love with it.When I started the project, I was too ambitious to realize all features above. Sadly I could not build even steering mechanism while keeping all wheel drive and independent suspension. So I changed the project to building another 8x8 vehicle. It ended up as my Tatra 813 Trial Truck, but that is another story. Focus on characteristic features Two months ago, I suddenly came up with an idea that enables both normal AWS and crab steering. In the case of four-wheeler, you can do it by switching rotation of second Servo motor for rear axle. But in eight-wheeler like Shaman, you should change turning radius of second and third axle. In normal mode, the steering angle of inner two axles is smaller than outer axles. But in crab mode, all axles should be steered at the same angle. This is the basis of steering idea. I used the way of fixing/moving pivot of steering linkage. A: There are two 7L steering racks connected to 7L beams. Front rack is connected in the middle of beam, rear is one stud backwards. Both ends of beams are connected to steering arms of each axle. B: In normal mode, rear rack is fixed by 12T bevel gear. So the fixed pivot of 7L beam is its 5th pin hole. Which makes front end of beam moves twice as rear end does. That means the steering angle of 1st axle is twice as 2nd axle. C: In switching crab mode, 12T bevel gear moves one stud forward and fix front rack. Fixed pivot is 4th pin hole of beam. Which makes both ends of beams move equally. That means the steering angle of 1st axle is the same as 2nd axle. And there is one more twist. D: I put main steering rack (moved by pinion gear) on one stud forward of 7L beam's front-end (which means 9L beam’s front-end). Seeing from the pivot point, this rack is connected to farther than the point of front steering arms connected. So front steering arms always move slightly shorter than main rack does. When Servo fully turns 90 degrees, pinion gear moves the rack in one stud sideways. Steering arms move less than one stud. This was necessary for keeping CV joint (connected to steering hub) rotate smoothly even when fully steered. Challenge and compromise First of all, this MOC is NOT amphibious. It is too heavy to float. And because of driving motors of low position, chassis is not waterproof at all. So it is not recommended driving it through even shallow water pool. My aim was to achieve decent crawling capability. But I had to lower the bar because there was no room left for portal/planetary hub reduction. Without them, heavy load from 81mm tires directly goes to 12T half bevel gears. First attempt was using two XL motors geared 25:9. I put each motor for left/right side of axle. The result was unsatisfied. Even when climbing over small obstacles, bevel gears often slipped and got damaged. So I replaced them with four L motors geared 3:1. Each one drives a pair of half axles. Thanks to their good speed and smaller torque, new drivetrain proved to be more reliable. Although bevel gears were still slipping a bit, I accepted overall performance. The picture above shows two L motors for driving right side of axles. The power functions switch for changing rotation of rear Servo motor is synchronized with moving steering pivot mechanism. In crab mode, rear 4 wheels steer opposite the same direction as front wheels. As always I used few of non-Technic parts. Big roof tile was used for saving weight, curve slope parts were better choice for filling the gap. LBG axles sticking out the roof are visible indicator for steering mode. They are mechanically connected to switching mechanism. In the video you can see how they work. Instructions available at Rebrickable. Building it in red is possible by using red parts instead of white. I hope you will enjoy building! -
[MOC] Lego Technic Chilli Crawler
PunkTacoNYC posted a topic in LEGO Technic, Mindstorms, Model Team and Scale Modeling
I present to you my Lego Technic Chilli Crawler! This is a complete makeover and overall improvement from my previous Carrot Crawler: http://www.eurobrick...howtopic=112037 Yes, I know. This is the second crawler that I named after a vegetable; expect more! Features: - Triangulated 4-link live axle suspension using 4 soft, black shocks. - 4x4 with one PF XL motor mounted parallel* to each of the two axles. A final gear ratio of 1:5.001, yes this may seem slow, but the enormous Super Swamper tires make up for it. - Speaking of that, 4 RC4WD Super Swamper tires. No, they are not Lego, I got them from a nearby hobby shop. - One L-motor for steering in the front axle, geared down via worm gear to 8 tooth gear, then a 12 tooth gear to a 40 tooth gear. The 40 tooth gear drives another 12 tooth gear that moves a 13L gear rack. - Portal hubs for all four wheels. Standard Lego Unimog for the rear axle for rigidity; custom triangular plate portal hubs on front axle for a steering pivot point closer to the center of the tire. - Good articulation, about ~55-60 degrees. - Controlled with an SBrick. - Powered by a Lego rechargeable LiPo battery. - Green Chilli Stem** * The mounting of the drive motors parallel to the axles was a must for this crawler. By doing so, I have not only eliminated gear slippage as there are no perpendicular gears, but there is also a ton more ground clearance in both the front and rear axle. The rear axle especially as the motor is actually on TOP of the axle. Crazy, huh? ** Makes the crawler look so much cooler. Challenges: - As with all 4-link suspension setups, the mounting and placement of both the links and the shock absorbers proved to be a rather annoying, tedious part of the process. I have, however, managed to make a VERY rigid triangulated setup where the shocks are not bent or warped in any way. - The mounting of the two lower links on the front axle was also difficult as there was virtually nowhere I could mount these links onto. I was able to (somehow) securely mount both the lower links and the shocks of the front axle onto 7L and 9L beams on either side of the motor. - Mounting the motors parallel to the axles proved to be hard, but actually somewhat straightforward when it came to the rear axle. I had been so used to having drive axles perpendicular to the axle like on my previous crawler. The mounting of the front drive motor was difficult in the fact that its power is transmitted through various gears and the motor itself is connected to the axle by two plate beams and a pin or two. Although the front drive motor is still not completely rigid, I have had no problems with gear slippage whatsoever in either axle. Some pictures: And finally, here is the youtube video: I welcome any suggestions or comments you may have. I will, however, say in advance that I DO NOT plan on making a body for this crawler as I designed it for performance purposes mostly, a Lego "comp-crawler" as you may call it. Thanks, pt -
Well Guys, i finished my newest MOC,the well known red Pickup from GTA V Character Trevor Phillips.The Canis Bodhi might be one of the most iconic Character Cars from GTA V because it`s a unique Vehicle and it has an interesting little Feature mounted on the Grill. Yes,Trevor had some good Times with Mr. Rasberryjam so the little Bear has to come everywhere. I tried to recreate the Car as good as possible and even added some Gimmicks like a Gun, a Shovel (to dig Holes for Bikers) and an Axe for....well chopping Stuff to Pieces. I also tried some detailing under the Car like the Driveshaft and a Pair of Exhausts. To complete the Pickup,i also tried to make two Minifigs of Trevor himself and Nervous Ron. I hope everyone likes my newest Creation,feel free to Comment and Like. 20161110_154908 by Christian Weber, auf Flickr 20161110_154924 by Christian Weber, auf Flickr 20161110_154931 by Christian Weber, auf Flickr 20161110_154946 by Christian Weber, auf Flickr 20161110_154957 by Christian Weber, auf Flickr 20161110_155029 by Christian Weber, auf Flickr 20161110_155038 by Christian Weber, auf Flickr 20161110_155054 by Christian Weber, auf Flickr 20161110_155119 by Christian Weber, auf Flickr 20161110_155137 by Christian Weber, auf Flickr 20161110_155434 by Christian Weber, auf Flickr 20161110_155442 by Christian Weber, auf Flickr

[42125 Alternate] Dune Buggy
paave posted a topic in LEGO Technic, Mindstorms, Model Team and Scale Modeling
My next alternate model of the 42125 set - Dune Buggy It's a replication of the well-known Meyers Manx dune buggy. Also the BF Injection in the GTA games. Size: L35, W19, H13, cm Parts: 665 Weight: 610g. Features: - Opening bonnet and trunk - Full independent suspension - H4-engine - Working steering wheel. A width is 2 studs shorter, than it's in the original set, so I used the floating differential suspension system. Working well. See the video: Instruction is available on Rebrickable: https://rebrickable.com/mocs/MOC-76011/paave/dune-buggy/ -
[MOC] Lego Technic Cactus Crawler
PunkTacoNYC posted a topic in LEGO Technic, Mindstorms, Model Team and Scale Modeling
Hey Everyone! Here is the successor to my Lego Technic Chili Crawler, the Cactus Crawler It took about half of a year of design and revision to reach its current state, of which I am proud of. THE VIDEO: youtube Features: - 3 L-Motors for drive (two in the rear axle, one in the front) - M-Motor and a small linear actuator for front steering - Rigid, triangulated 4-link suspension for the front axle, with large, soft, black shock absorbers - Extremely rigid 2-link rear suspension with ball-joint pivot point on top of the axle, similar to that found in the RC "Mantis" crawler - 100% Lego-legal custom curved rear links that, with how the main cab is shaped, provide exceptional ground clearance towards the rear of the crawler, allowing it to climb up relatively large vertical structures such as street curbs - Very minimal, light bodywork - BuWizz for extra power and SBrick for a great, custom control scheme Note: By the time I finished designing the cab and it's battery enclosure, BuWuzz had not yet come out with the update for their iOS app that allows a single joystick/slider to control multiple outputs, so I was forced to use an SBrick with the BuWizz, providing the extra power from the BuWizz, but with the ease-of-use and great custom control profiles of the SBrick. When used with the SBrick, the BuWizz does in fact still provide more power than the standard Lego 8878 LiPo battery box. - RC4WD 1.9" Krypton scale tires - Two green pieces so that I can call it the Cactus Crawler ;) LXF hopefully coming soon, the tires can easily be found with a quick google search of their name. YES, I know, there is no body. This is meant for performance, meaning I made the cab as small, light, and rigid as possible. I will be able to reply intermittently throughout the day. I figured I'd put this up now anyway! pt -
[MOC] 6x6 Ural 375D
Sariel posted a topic in LEGO Technic, Mindstorms, Model Team and Scale Modeling
I present a little off-road experiment of mine. It's a large-scale model of the Soviet Ural 375D heavy-duty military truck, a truck I've had the pleasure of driving last year. The model's look is somewhat compromised but it achieved the primary goals, which included stress-testing the planetary wheel hubs, the new differential and my 4-speed remotely-controlled sequential transmission. I'm happy to report that none of these components failed and the truck, which weighs 3.94 kg, is able to drive over a 6 cm tall book or climb inclines slightly above 15°. It's not a perfect model, and it's truly sluggish, but oh well. Functions: remotely controlled drive and steering remotely controlled 4-speed transmission (with the lowest speed disabled so I could use a PF Servo as shifter) remotely controlled pneumatical locking of differentials in all three axles 6x6 drive suspension: live axles #1 and #3, pendular axle #2 (for improved chassis rigidity and to maintain ground clearance) switch-operated rear winch opening hood with a V8 piston engine running at constant speed and opening doors and a tiny detail that I really wanted to get done: a see-through grille -
Eurobricker’s Share your Trailers!!!
CrazyKreations posted a topic in LEGO Technic, Mindstorms, Model Team and Scale Modeling
Hey everyone, you must check out the share your trucks forum for many talented eurobricker’s inspirational truck designs! But this topic is for those who have made their own custom trailers and mods that they are proud of! I will start first Here is my trailer for my custom Semitruck. I am currently designing a nice off-road capable caravan which I hope some of you would like to see, I am almost finished and I will post it here when I am done. -
The Crumbling Bridge Last November I built a MOC in which two weird guys lived 30 feet in the air in minimal but cozy stilts. It was called Stilt Houses precisely. In the diorama there was also an off-road vehicle for which I wanted to build a small dedicated setting. Recently I came up with the idea of creating an ironic scene with some building techniques that I had never used, such as the rocks made of many dark bluish gray slopes and inverted slopes. The diorama is quite small but cute, and it manages to get a smile, in this period there is a need… It is mainly composed of three parts: two rocky blocks covered with shrubs and a crumbling bridge that joins them. In the middle the all-terrain vehicle is crossing the bridge escaping from the hungry bear to take shelter on the stilts. Hope you like it! Thanks for stopping by!

Hi, I am building next MOC based on model which can be found in the game Snowrunner. I picked KHAN 39 Marshall - it is based on real world vehicle - UAZ 3151. I would like to ask for your advice with one of my biggest problem in mocing - creating a decent looking body. When you see the photos and think "It doesn't look like UAZ..." then YES - you are right and: I wish to focus on body and look (I don't want to discuss functions here, they are there and they are fine). As you can see, the main color is picked (some parts in proper colors are missing, but is not a problem when bricklink is around, the same goes for some missing obvious parts), but any smaller recolors are possible. The biggest problem I have is the front grill. It looks almost ok, but as the grill for Jeep or Land Rover, not the UAZ. I tried to recreate UAZ grill, but I failed miserably. As you can see, there is no much space for it and I am also very pleased with perfect connection of the front and the hood and I definitely will keep that. Important factor is also the fact, that body needs to be as one piece, which can be easily removed, so the body demands some rigidity. Also I plan to add front and rear lights, but at first I need to be sure that the body is right. So, could you help me a little to improve the look so it would be closer to UAZ body look? :)

Hi everyone, I have wanted to make an off-road truck for soo long and I just have enough time to build and design one. But I desperately need some expert opinions on how to design the front cabin for this vehicle. Does anyone have any ideas or designs you would like to share? ps I am looking for a design kinda like this: -

[MOC] Rock-Bouncer
mktechniccreations posted a topic in LEGO Technic, Mindstorms, Model Team and Scale Modeling
Hello my friend. This is my another asset to this forum in form of a off-roader/rock-crawler in this particular case its more like rock-bouncer, the reasons are follows. This MOC is powered by 3L Power function motors, which two of them are located in the rear axle, to help during uphill climb with more torque requested on the rear axle and overcome any obstacles Gear ratios are as followos, from motor to the axle its 3:1 to speed up the model, and afterwards it connected to new planetary hubs with theire respective ratios, steering is controlled by one servo and everything is controlled by one buwizz brick. Instructions are avaible at rebrickable: https://rebrickable.com/users/MK.Technic/mocs/ More photos on bricksafe page: https://bricksafe.com/pages/MK.Technic.Creations/rockcrawler-2l Video
