  1. Hi, I would like to present my newest MOC. It is off-roader with look based on UAZ 3151 and equipped with functions available in off-road game Snowrunner. Main functions and some details are listed below. If anybody is interested with some more technical detailes (and I believe there are people here, which are more focused on technical aspects of the MOC rather than the look), which are hard to show in short video, then I encourage you to scroll down, below photos. If not, then I believe that video and some photos should serve just fine. I also added short video to present couple of tests of Uaz frame and powertrain. Instructions will be available in the future :) Details and main functions: scale 1:10,5 dimensions LxWxH: 38x16.5x18.5 cm weight: 2.44 kg (without additions) 4x4 drive (2xL motors) steering with ackermann geometry (servo motor) adjustable height of suspension for both axles (M motor) lockable differentials on both axles (mechanism without pneumatic, secured with clutch, M motor) live axle suspension, front and rear working inline four piston engine with fan and detailed engine bay lights: front, rear, roof - controlled by manual hidden switch openable hood (with support rod), trunk, four doors locks in all doors and trunk working steering wheel with realistic number of turns and with adjustable position easy removing the whole body easy change to version with or without the roof adjustable front seats - leaning and moving back and forward split rear seats with folding backrest to increase trunk capacity openable glove box easy access to battery pack for replacement Instructions: https://rebrickable.com/mocs/MOC-75601/keymaker/off-roader-uaz-3151-aka-khan-39-marshall-4x4-rc/#details More photos: https://bricksafe.com/pages/keymaker/7.-uaz-3151 Drive I designed the drive to be balanced between speed and torque. Main idea was to make drivetrain strong and reliable. I used the strongest differentials, new reinforced CV joints and bevel gears whenever possible. What is more I tried to keep high speed – low torque rule as long as possible when designing the drive train. As the result, the biggest reduction is placed on axles – on differentials. Thanks to that and reinforced construction you will stall 2 L motor rather than hear some gear slipping. Look In case of look, I keep in mind to avoid blue pins whenever possible, keep nice, clean one colour chassis which can be seen underneath and focus on small details, both inside and outside. Also you will not see many holes in the body or ugly cables, despite the fact that there are 5 lego LEDs there. What is more, all lights, along with the switch are integrated into one piece removable body and can be easy removed only by disconnecting single cable. Performance The plan was to make it very capable when off roading. And it is, when you remove the body. The look and those many details and manual features, all related to the body come with obvious price – weight. UAZ weights 2435g in basic configuration, but only the body itself weights 855g. So if resign from features, which are related stricte to the body and replace the body with some light weight one, then you will get very capable machine. But even with the body, thanks to drive train design, off-road capabilies of UAZ are pritty decent, as showed on the video. If you have more questions, do not hesitate to ask. And keep MOCing! :)
  2. Hi everyone, I have finished my Willys Jeep alternate of the Land Rover set, so I'd like to summarize the final model here. Features: - Live axle suspension with imitated leaf springs on both axles. It uses one shock absorber per wheel, also positioned realistically. I also tried to construct the core frame as is in the real life car. - Manual 4-speed gearbox in a classic H-shape. Additionally, there is a Hi / Lo gear switch and an RWD / 4WD switch, just like in the real car, and the positioning of those switches is as realistic as I could get with the limited space. The whole gearbox is in the middle of the chassis. - Working inline 4-piston engine as in reality, I tried to add engine details modelled after the real engine. - Functional steering wheel and also HOG steering in the back (which had to pass through the gearbox). - Foldable windshield and opening hood with stander included. I managed to get the windshield folding joint similar to reality. - The interior is clean and I tried to get the shape of the seats as close to reality as I could, although the square and flat front seats were hard to reproduce with the available parts in that color. - Detachable roof, again, I tried to reproduce the shape of the tubing. - Extras: Jerry-can on the back, and of course the spare wheel. More details about the design process are given on Rebrickable. Here's a video showcasing the functions: And some renders and photos: Building instructions are available on Rebrickable. Feedback is welcome! Cheers!
  3. I’ve always wanted to make a trophy truck, here’s my take on one:) I call it the panther because is black, and the headlights make it look like a cat:) It features long suspension travel just like a real trophy truck. Here is the bare chassis. Chassis and body side by side. Specs: Drive two l motors steering servo motor battery BuWizz 2.0 suspension rear, three link front swing axle independent if you have any questions please ask;)
  4. Hi, I'd like to share my second C model for 42099, inspired by the recently released off-road buggy. The design goals were 1) faster speed 2) responsive and long suspension travel 3) lightweight and curved shape.The wheel hubs and the differentials perform down-gearing, so I decided to apply 3x up-gearing by a ratio of 5:3 and skip the differential to make it faster than the original. Since the differentials are not used, the small gears can be used for up-gearing with perpendicular meshing of gears, which is smoother than the parallel meshing of the 20 and 12-tooth gears. I decided to use rear wheel drive only, one motor driving each rear wheel. I managed to compact the drive-train with the following setup: For suspension, I wanted a long travel and a wider wheel base, so I tried to increase the length of the swing-arms. The rear suspension seemed simple with 7L beams, but the front suspension was more difficult, as I had to increase the length of the 6L steering arms in the set by 1 stud, so I had to apply some tricky workarounds. Furthermore, I wanted a lightweight axle with a positive caster angle, with the steering motor integrated closely to the axle. The result has more than 6 studs of ground clearance and 3 studs of travel and is quite responsive: The battery is integrated into the middle of the model to distribute the weight between the two axles, and to provide easy access from the bottom. The whole base looks like this: The bodywork proved to be the most difficult to get right, since the panels available in the model are hard to use to get the light-weight frame-like body that I wanted. After taking some inspiration from the shape of Madoca's Blue Lightning buggy, I got the hang of using the arched pieces and the flexible hoses to build the curves, and used some of the panels to finish the body with a simple roof and hood. The roof is attached very strongly to the base, so the car can be lifted by it.As the small grey seats in the original just didn't feel like a match to the overall shape and scale of the model, I gave building a custom seat a try. Luckily, the few available red pieces were just enough to make a black seat with two red stripes :) I think it adds a lot to the overall look of the model.Here are a few more pics: Finally, here's a video of it in action: Building instructions available on Rebrickable. Let me know how you like it! Cheers, Viktor

    [MOC] RC Buggy

    After 42099 and the whole new PU system, I'm here with a MOC that uses something a bit older - RC system. After all these years it is still the most powerful 100% LEGO solution. Watch it in all its glory: Features: RC drive - 2x RC motor, geared 3:1 (slower output) RC steering Front suspension - double wishbone, soft, long travel, positive caster angle, 7 stud ground clearance Rear suspension - floating axle, soft, long travel, 5.5 stud ground clearance Please watch the video to see this machine in action and for more details. I hope you liked this model.
  6. RC Off-roader with Dual Diagonal Drive I think I'm onto something that will get me through the winter. Summary Dual diagonal drive means: 1) dividing torque over two separate drive trains while 2) preserving the advantage of having open differentials when cornering and 3) passing diagonal tests without using differential locks. Background I have been playing with this idea for a while already, especially after seeing @KevinMoo's dual drive models (Mitsubishi Pajero and Dual-Driveshaft Pickup). @KevinMoo rightfully addressed the vulnerability of LEGO parts in RC models and the fact that using independent drive trains for the left and right sides, loses the benefit of differentials while cornering. This got me thinking. Using independent drive trains for left and right in a 4WD model does indeed drop the benefit of differentials while cornering, but what if we would pair the wheels diagonally, so pair the left front (LF) wheel with the right rear (RR) wheel, and pair the right front (RF) wheel with the left rear (LR) wheel? The resulting 'dual diagonal drive' (I borrowed the term from the electric skateboard scene) would serve two major benefits: While cornering, the LF and RR wheels will average to a speed that is very close to the average speed of the RF and LR wheels. So not having an open distribution by means of a differential between the two drive trains is much less of a problem as with separate drive trains for the left and right side wheels. On a very uneven surface, where one or two wheels may lose contact with the ground, the wheels that do have contact are typically lined up diagonally, see image. With dual diagonal drive, the vehicle would still have traction, even without locking any differentials. Only on slippery surfaces, there are chances of spinning wheels. So this is what I'm thinking of. We start with the basic dual diagonal drive setup: Two separate drive trains, one for the LF and RR wheels and one for the RF and LR wheels. The drive trains cross using two 24t gears and an auxiliary 16t gear that sits right underneath the auxiliary axle for the other drive train. So no clutch gears are involved in this crossing. I inserted a 1L Technic liftarm inside each differential - idea from @Madoca 1977's Toyota Land Cruiser 80 - to prevent the bevel gears from popping out. Next we add a manual locking feature, which closes the differentials with a single lever. This locking feature will force each pair of wheels involved in one of the drive trains to have equal speed. Now we connect each XL-motor to one of the differentials, using a small 4-speed gearbox. That means; two separate 4-speed gearboxes. This may be a bit ambitious, we'll have to see in real-life whether this is feasible or not. I might fall back to two 2-speed gearboxes. I did pay attention to the amount of torque in the transmission though. I geared up the XL-motor outputs and geared down the transmission output. That makes the transmission spin faster with less torque. The gearboxes are operated synchronously using a 90-degree stepper, which is controlled by a Servo-motor. Each gear shift axle has its own 90-degree limiter. And finally the outputs of the XL-motors are transferred to a fake V8-engine via a normal differential. The sole purpose of this differential is to combine the XL-motor outputs for the fake engine. For the steering I'm thinking of using a servo motor. I don't really like the directness of steering with a servo-motor, but the steering link attachment points are moved one stud backwards, which confines the steering angle. This adds to better handling and protects the CV-joints in the wheel hubs. I don't know where this is going to end. I'm not even sure about the exact kind of car I will be targeting, but it sure needs to be some kind of all-rounder. Comments and suggestions are welcome.
  7. After long pause, I sat down today to play around with LDD. Oddly the inspiration came from here - see below. This will be a concept UTV for King Of Hammers, first design is ready, I need to build IRL and test. Considering the Corona situation, it might remain digital for a while though, as I might not have all the necessary parts on stock. 323 pcs so far. Nothing special in terms of functions: suspension, HOG steering, differential with fake engine (easy pop-on/off), fake automatic transmission. The latter is just sume pulley wheels and gears rotating along with the cranckshaft, round and bulky, just like a real hydraulic one. In real model, I will fit the tire on the inner wedges of the rim, thus it will get a bit higher (~58 mm) but narrower (~22 mm) profile.
  8. As a tribute to this truck this project shows some of the unlimited possibilities. It is a model of a KrAZ 255B 6x6 off-road truck which is used for extreme applications. Even though this specific truck was never produced as a civilian truck however after its retirement it has been used as such. Within a couple of minutes it can be changed into one of the four different editions which include: - Semi-truck with fifth wheel - Ballast tractor with ballast box - Trial Truck edition - Log Truck with stinger steered trailer So it is up to you what kind of job it does: just having fun as it being a Trial Truck, or will you give it a semi-trailer? Or will it be hauling logs? The truck features: solid axle suspension on all axles of which the rear axles use a tandem bogie suspension, PF powered driving on all axles 6x6 drive, reduced speed to increase power/torque, Servo powered steering, fully functional fifth wheel, modeled V8 engine, detailed cabin interior and two light units. Actually you could build this yourself. Building instructions and inventory/parts list are available. Early in the building process you will see what it is that you are building. You will be very excited from the moment you start the build of "Truck T14" KrAZ 255B 6x6 till you finish it with about 290 different parts totaling 1800 pieces. Scale: 1:17,5 Length: 477 mm (+ trailer 926 mm) Weight: 1,92kg (+ trailer 2,41kg) Parts: 1840 (+ trailer 2270) This KrAZ 255B 6x6 model is powered by a YaAZ-238A V8 4-stroke Diesel Engine which is visible with the hood opened. This power source has 8 cylinders in a V setup with a displacement of 14,87 liters. The initial YaMZ-238 delivered 215 hp with a torque of 785 at 1500 rpm. Since 1966 the YaAZ-238A engine was installed and delivered 240 hp with a torque of 883 at 1500 rpm. This detailed V8 engine is nice to build and to give it those realistic looks a total number of 80 parts is used. It is detailed with for example air filter, fan, fan belt, pulleys, hoses, by-pass oil filter and the exhaust system. Both L Motors, which are used to power the truck's drivetrain, are positioned laterally on each side of the chassis. The rotation of both L Motors is reduced using a single gear reduction one for each. The power produced by these motors individually is merged by the length differential. To increase off-road capabilities it has limited slip applied. One out going shaft is powering the front axle, but not without being geared down once more. The second out going shaft of the length differential is powering both rear axles. Both rear axles have there own gear reduction which is equal to that of the front axle. Again limited slip is applied, but to the rear axles only. The front axle has Rubber Belts installed instead of shock absorber. It's double rear axle setup is fitted with a tandem bogie suspension. The use of this setup allows easy axle and wheel travel. Both front and rear axles are fitted with "Technic Steering Wheel Hub with 2 Pin Holes". These hubs have proved to be a real improvement, less friction and the wheels do not bend under the weight of the model as it would without. Semi-truck with fifth wheel For a basic configuration a fifth wheel is mounted. Because of this a semi-trailer can be hooked up. Since this is a common application it makes the truck extremely versatile and depending on the used trailer it still suites any kind of terrain. At the rear end of the chassis has wedges installed to allow easy attaching of any semi-trailer. By adding a winch the versatility can even be increased. The battery box is simply sitting behind the cabin and the spare tire is mounted to the truck's roll bar. Ballast tractor with ballast box As used to haul extremely large and heavy loads this truck can be fitted with a ballast box. What it basically does is adding weight to the rear axles to improve traction. While fifth wheel mounted trucks have there semi-trailer to add weight to the rear axles it is now replaced with a ballast box. The truck's battery box acts as the actual weight. A spare tire is mounted that fits the truck as well as four spare tires that would fit for example a drawbar lowboy trailer. Trial Truck edition To be used as just an off-road truck to fool around with a trail truck body can be installed. To distribute the weight of the truck equally over all axles the battery box placed on top of the rear axles. Even though spare tires are not common for trail trucks two are installed to improve the looks of this truck. It is always impressive to see a truck with these large wheels having some spares. Mounted to the roll bar and easy to access when needed. Log Truck with stinger steered trailer Using this truck to transport logs requires to additions. The first one is a bolster mounted to the truck's chassis. It is sitting directly on top of both rear axles which enable good weight distribution. Second is the stinger steered trailer. Basically this trailer is a large tube with a tow ball at one end and a partial chassis with a bolster and two sets of wheels attached to it. The two sets of wheels are attached to solid axles which uses the same hubs as the truck does. Essentially the axle setup is equal to that of the truck without the drivetrain. Again it uses a tandem bogie suspension setup which allows easy axle and wheel travel. To hook it up to the truck it has a tow ball which connect to the truck's tow ball socket. The trailer's bolster is exactly the same of that of the truck and both are foldable. Finally the partial chassis with the axles and bolster attached is slidable. Allowing the full log combination to haul different lengths of logs.
  9. Ladies and Gentlemen, Boys and Girls, BEHOLD: The Mighty MAZ 7310 Uragan Cargo Truck, in LEGO! This massive set, which I have designed over the course of two years, stands almost ten inches tall, two feet long, and is comprised of almost 7,000 pieces. I sat at my computer for hours a day, sometimes, surfing the web, looking at blueprints, building, deleting, building some more, etc. And now, finally, I can reveal my masterpiece to the world! Bwa-ha-ha! Okay, anyway, I have designed my set for maximum playability, stuffing it full of all sorts of awesome goodies, like opening hood, doors, tailgate, and utility boxes. A removable roof, folding rear seats, free-spinning wheels (including the steering wheel), two Diesel engine options, a generator, compressor, radiator, Master Mechanic's Toolkit, fuel and water drums, 12v batteries, large cargo container, winch, wide-load flags, roof racks, warning beacon, fog lights, two sets of mirrors, lightbars, and more! (Whew! I'm out of breath!) Now, for the real machine: The MAZ 7310 (Minsk Automobile Plant, in Russian), was a large 8-wheeled Missile Transport truck built in the 1950s and 60s. Soon after, people started using them as cargo trucks, tankers, tow trucks, and airport fire trucks. Alright, that's it! Thank you all for looking at my LEGO creation! If you have any questions, comment, I'll do my best to respond ASAP. Happy building and have a great day! Update: Also, some of you may have noticed that the cab of the real vehicle is slightly longer. This is true, I had to shorten the LEGO version out of necessity, as the extra length could’ve affected my MOC’s stability and structural integrity. I suppose I could probably figure it out eventually, but I like it how it is. Thanks for understanding!
  10. Presenting another trial truck - 4x4 - PF: XL, Servo, IR, LiPo - Leaf spring front suspension - Double soft shock rear suspension - Panhar rods for both axles - Opening hood - Removable body. Prepared it for the Trial contest in Moscow, but couldn't come there, then participated in the Truck Trial competition in St. Petersburg. You can watch the performance here: Time: 13:41 and 54:33.
  11. I' ve decided to make an alternative model for 42054 CLAAS XERION 5000 TRAC VC set. I' ve wanted to design something different from all those excellent c models already made, so I made a truck capable of off-road conditions, with crane and many other functions. The result: Functions: rear axle drive with 4 piston engine steering live axle suspension side outriggers cabin tilting rear PTO (power take off) crane arm rotation crane arm 1st stage elevation crane arm 2nd stage elevation grabber closing/opening Please watch the video to see this machine in action and for more details. This model is powered by one m motor with rotation direction selection. It powers main selector, crane selector. and PTO. Main selector switches between worm gear powered functions and arm rotation. When worm gear functions are selected, there is another switch to choose between outriggers and cabin tilting. The crane selector switches between 1st and 2nd stage elevation. I had to use some interesting (I think) solutions because of parts selection in 42054 set: Piston engine There are no piston engine parts in the set, so i made them from some connectors. You can see it working in the video. Suspension There are no shock absorbers or wishbones too. So I' ve made a suspension based on twisting axles: Every wishbone is suspended independly. 3 of those connected to axle make a well-working long travel soft off-road suspension: Grabber There was a grabber in original set, but when building the grabber I've already used the worm gear for more important functions, so I' ve designed a different locking mechanism: Turning the green axle makes the red grabber frame move up and down and becouse of engaging the blue knob gear with h-frame opening and closing blue grabber. Instructions Instructions are already available here on rebrickable! I hope you liked this model.
  12. Hi to all fans of Lego! Today I want to share with you my new work - Rock Rod Rock Rod - it's the crawler, on the construction of which I was inspired by the fierce custom projects from HAUK Designs. Especially, where, no matter how on the crawler to run a fresh RC DC chequered flag STT PRO rubber wheels and BuWizz. At the output was a relatively light on the portal bridges crawler. At the heart of the model is also the philosophy of placing motors on bridges, to reduce the center of gravity and minimize weight and inertia of the body. Technical characteristics of the model: Weight (together with a technic-figure) - 817 g. Number of parts - 617 pcs. Steering - Servo motor Movement - two L motors Power / Control - BuWizz Even the "sofa" trial allows us to understand that additions such as non-standard tires and BuWizz significantly expand the scope of use and possibilities of radio controlled Lego models. It remains to wait until the snow comes down, to ride Rock Rod on the rocks. But you can do this before me, by building the Rock Rod yourself by free video instruction. I plan to test the model in the spring on a severe off-road. I will be very glad to hear from you any advice or wish for the completion of both the technical component of the model and its appearance. Ahead is still half a year :)

    [MOC] SUV Racer

    Hello All! This post is updated with new video: Today I want to present my new MOC – SUV Racer! AWD, independent suspension, four buggy motors (slow output), 52 x 24 x 19 cm, total weight – 2.5 kg. No universal joints, no diffs, no S-brick :) True action: Photos: Short movie about my trip with this model: Thanks for watching!

  16. After seeing lots of different takes on the Land Rover (of various eras) I was inspired to design a minifig-scale version of the Series 2 for my nascent 1950s British village. LDD instructions are available here: https://bricksafe.com/pages/Zetroc
  17. This is Lego's 42056 Porsche 911 GT3 RS set with some unique rallycross-inspired features I added making it the perfect sports car to drive in the snow. Features Suspension system raised to make the car about two studs higher Wheels and tires from the 42037 Formula Off-Roader Mudflaps LED light bar Front off-road lights Rear bash bars Optional snowplow that attaches to the front The lights are fake and don't turn on, and all of the other lime-colored pieces are from the 42037 set as well. I had a lot of fun making this. I just had to switch of the area of the springs to change the height for the rear without any pieces needed, but for the front, I had to remove the entire Porsche's body to make the lift there using a variety of pieces. Overall, I'm proud that a got the result I wanted, which was making the Porsche 911 GT3 RS higher (so it wouldn't bottom out) and equipping it with off-road features so I could have fun with this set in the winter. It does need to drive in snow only about an inch high so I could move it without getting stuck (and so the plow can move the snow too). I recommend to anyone who has the Porsche set to try these mods out for themselves this winter! Here's some more pictures of the car and a desktop wallpaper that I created wishing everyone at EuroBricks Happy Holidays!

    Lexus GX EV3

    "The Pursuit of Perfection" - slogan of the Lexus brand. I'm now back with my greatest Lego creation ever. A 2010 Lexus GX 460 with EV3. It's a replica of my Dad's car, but this one's in gray with black interior. I made it as much as I could to the real car, thanks to pieces from the Arocs and Porsche set. Features Sariel's 4-speed sequential gearbox controlled by a medium motor All-wheel-drive Independent suspension Rack-and-pinion steering Fake V8 engine Six seats (could not fit a seventh one) with the rear four being foldable Opening side doors, trunk door, and hood. Detailed interior The gearbox and the two differentials in the car like to click while moving (especially on rough terrain) around, but the result was a car that was heavy, slow, but also makes lots of torque. I'm very happy with how this car came out and I couldn't have done it without all of the helpful people on the Lego community and EuroBricks. Thanks especially to my good friend TheMindGarage for never making me give up. Now I can officially call myself a true master builder. Check out this build on my EV3 community account too for more photos and information about it. I would love to make a YouTube video soon about the features of the GX EV3 and footage of me taking this build on some dirt trails in a park. I also want to take a picture of this right next to my Dad's actual car. So please follow this post to check out some stuff I might upload in the future! To finish this post, here's some collages with photos of the GX EV3.

    Crawler 4x4

    How about that little cross between mud and go on the rocks? Crawler 4x4 always ready for it! Still would! Its wheels are shod with tires RC Rock Crusher X/T 1.9, coupled with portal axles and two motors running by SBrick and LiPo battery box - we have an off-roader with excellent maneuverability, suspension geometry and a low center of gravity due to the unsprung axles. Crawler 4x4 built under the rules of the forthcoming Off-road trial competition in Moscow, at the same time. I tried to build the chassis in such a way as to achieve maximum throughput and maximum flexibility - namely, so this chassis can set the wheels of virtually any size from 62 to 108 mm. The body of the model removable. This allows the chassis to this every body, even though the truck, even an SUV. Get more photos on my blog of flickr
  25. I'm back with one last issue in my GX EV3 build. I just got done finishing the doors, side panels, rear trunk door, hood, and some part of the roof. But the vehicle was so heavy that when I drove it around, it kept on doing the same thing. The diffs were clicking and the car had very much difficulty moving. Here is a picture of the bottom of the vehicle. Most of the clicking seems to be coming from the rear diff when I move the wheels by hand. I can either do two things. 1. Reinforce the rear diff somehow. 2. Improve it's off-road performance and stop the clicking somewhat by replacing the diffs with knob gears. But this will come at the cost of independent moving between the wheels. What should I do? Please give me the best response you can so the clicking will stop and I could finally take this AWD machine through some rough terrain like a real SUV. I really appreciate any advice.
