  1. Hey Eurobricks, PunktacoNYC back again with another rock crawler! This time it's called the Rocket Crawler and it is my largest, fastest crawler yet. Youtube video: Features: - 4 L-Motors for drive (one per wheel) - Ackerman steering with custom virtual pivot system to maximize steering angle - Rigid, triangulated 4-link suspension with 100% Lego-legal original, extra large links - Very minimal, light bodywork, and a cute rocket atop the cab - BuWizz for extra power and SBrick for a great custom control scheme - RC4WD 2.2” Bully Competition Tires The initial inspiration for this crawler was twofold; I wanted to build a RC competition super-class-like crawler, what with giant relative wheel size, slim body, and high articulation. I also really wanted to make use of RC4WD's quite large Bully competition tires. This project has been in development for over a year thanks primarily to issues with the front axle. The problem with the front axle was that Lego universal joints simply could not handle the high torque required to spin such large tires. I tried using custom Lego universal joints custom dremeled brass remote-controlled boat u-joints, and even knob gears at the pivot point - nothing worked. So, I mounted the motors directly to the wheels, all within a virtual system to move the steering pivot closer to the center of the wheel for a better turning radius. There is approximately 90° of articulation between the front and rear axles: Easily adjustable suspension height: (high) (medium) (low) The chassis: Wheel comparison: Concept 1: Concept 2 (later): This has been my favorite project. Let me know what you think. P.s. I got a snupps page (nice idea, Sariel): https://www.snupps.com/punktaconyc
  2. I think anyone who ever used the portal hubs came to this issue. The hubs simply have the steering pivot point so far from the center of the wheel, that you need to either reduce the steering angle, or have a model with large fenders. Today I came up with this simple mechanism to compensate for that by simply turning the whole front axle in the opposite direction. The two tilted 6L links are usually used to keep the axle from moving forwards/backwards. In my case they are attached to the steering rack at a high angle. Moving the steering rack will cause the geometry of the axle to change - rotating it to (mostly) compensate for the large pivot point: Of course this is just an idea for now, but it should be easy to implement on a real model. The wider the axle, the better the compensation. Of course the axle has to be designed in such way, that suspension, drive and steering system will be able to work with this degree of movement.
  3. So here's the idea: seeing as all large and complex Technic submissions have failed on LEGO Ideas so far, I set out to create a very small and simple, yet fully functional 4x4 crawler. This is the result, which can be considered the 9398 set on a budget ;) as it offers pretty much the same functionality in a considerably smaller package. If you're willing to give this project a shot at becoming a set (a Technic Ideas set would be nice, at long last), please support it here: https://ideas.lego.com/projects/ba4cebf3-1f80-497d-9ecb-faee2dbc1df3 Photos and description: http://sariel.pl/2018/11/4x4-jeep-wrangler-trailcat/
  4. Today I want to show you my newest and fastest ever car. Ariel Nomad British light weight car based on twin brother Ariel Atom - one of the fastest road cars. Nomad like buggy cars have only rear wheel drive. During construction I recived also BuWizz brick for review . I decided to put it in the vehicle and show the diffrence between Power Function and BuWizz when presenting new model. It allowed to increase its power and simultaneous weight loss. Technical data: -Lenght 29cm -Width 18cm -Height 13cm -Weight 810g (Buwizz) -2x XL motors -1x Servomotor -1x Extension cable -Buwizz or small BatteryBox + IR tower In my car, I tried to reproduce the best possible vehicle mechanical construction. It has a independent suspension which on the driven rear axle turned to be a quite a challange in medium size scale. In my model I dont use differential to bulid drivetrain. Power is transmitted directly with a ratio 3:1 from two XL motors. Despite small size of BuWizz I failed to put fake engine, but I am happy with weight of car because it was possible to have weight under one kilogram. For me, Buwizz is the most practical third party controling brick. It offers everything in one practical case. My only small objection is the inability to use gaming pad to steering but I think that it will be possible in the future.

  5. Hello everyone, here again with a new MOC. Nissan Patrol GR II (Y61). (Updated - body lowered by 1 stud and some panels replaced by plates to reduce weight. Fifth generation of patrols before restyling is my favorite. A lot of experienced offroaders love it too, not without a reason. Update - outdoor trials video: This is a 3-door version which is much less common than 5. All the dimensions are strictly scaled 1:10. Taking into consideration that the real 42 inch tractor wheels definitely require suspension lift and are 106cm long. Also it is 3 doors and not 5 just because of the scale I've chosen. 5-doors would be something around 80 studs long, considering paneling and other stuff - that would be too heavy for an offroad vehicle. Dimensions: 45cm long x 18.5cm wide x 22.5cm height. Weight on the video: 1750g. I wanted to build a working vehicle, not just a standing brick, so I had to sacrifice some things to get it into optimal weight condition. The front is the visiting card for Patrols (imho). Think I caught the main features. All photos: https://bricksafe.com/pages/gate/gate-lego-technic/nissan-patrol-y61-suv The most effecient gear reduction was this one (no reduction from XLs to the transmission): In my previous MOC Ural 4320 I used a similar reduction, but 1:3 slower in the gearbox. It was really slow and couldn't compensate the speed with torque. Resulting - it could go from an obstacle steadily, but not climb it - if it was a large hill. Not only this one is faster, but has a shorter transmission, which is always good for models. No strain axle - steering ball joints is at it max bent position, giving a nice clearance. Always a minimal height limitation when using 9.5l shocks. I could cut off a stud here and there, but this position I liked most of all. The body is fully modular - axles, engine part, chassis and panels: Took it for a hard outdoor drive and of course made some pictures: Think I have failed this MOC, because: - I wanted both front and rear axle diff lock, but just couldn't find space in the front with winch on top (Update - actually not a problem at all. If it doesn't sit on its axles, it moves out of almost every situation (with winch 100%)). - This model literally wouldn't drive with many other gear setups (originally tried 2PF L and 20 beavel gears locked differential, but may be because of the weight, may be something else - couldn't make it cross obstacles without gear crack). - The weight is not distributed evenly between axles, with an overweight on the back. As you can see in the video I've taken some parts from its back to more or less stabilize it. - Design has some holes and is not so smooth - result of purpose of this vehicle - which is offroad. Many small detalization parts were falling off. So with quite a few rebuilds was getting rid of them up to this point. With 41999 for scale: Summing it up, I like it a lot. Really enjoying using it for direct purpose. It rolls over, crashes, but is extremely satisfying. Feel free to criticize.
  6. 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!
  7. Hello everyone. This is my first MOC that I am not ashamed of showing;) Ural 4320 on a shortened 4wheel basis. - 2 XL paired for driving - m motor for steering - m motor for 2step gearbox - m motor for rear differential lock - openable hood and doors - live axles with portal hubs - flexible flat body-chassis - powered by Buwizz 2.0 Total weight is 1800g. Length - 0,52 meters. Width - 0,26 meters. The idea was to make a trial truck in a bigger scale but still capable of handling heavy offroad. The model was inspired by Madoca's Jeep Concept and has the same general idea. Including paired 24x8 low gear and a 16x16 fast gear. Plus the portal hubs. But it is 4 more studs wider and ~10 more studs longer. It has live axles and a flexible body which results in a really stable construction. As of a few hours of heavy outdoor testing it didn't roll over once. As it was the first MOC I focused on the functionality rather than on design. Feel free to give me a punch for scarcity of design;) It looks odd but drives really well on a low gear. On a faster gear the 2 paired XL motors start chewing on the gears while offroading, On the flat surface it's fine though. Originally it just had a straight m motor to the 8x24 gear for steering, but due to heavy tension the gears or the motor were going off its clips. So I decided to make a steering through the small line actuator fixated in every possible way. As a result it was super sturdy and stable. The chassis (looks pretty compact without tractor wheels): Gearbox: Hope you like it Let me know what you think of it!
  8. 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.
  9. LEGO Tatra trucks are dime a dozen, but whenever I see them, they are either very large, complex and sluggish, or they are small but don't really have the unique Tatra suspension, nor drivetrain, nor steering. So I set out with a simple goal: make the smallest Tatra model I can that has it all: the suspension, drivetrain and steering just like in the real Tatra truck. This is the result:
  10. This is my new 1969 Dodge Charger Monster Truck. It’s a hybrid, a chimera. It’s an all-wheel drive, all-wheel steer monster. I built it in sections. It is very easy to build and assemble. I had to sacrifice passenger seat to make room for IR receivers. Quick reference of the features: - 2 XL motors for drive, one for each axle, - Tatra suspension, - Loads of suspension travel, - 2 L motors for steering, one for each axle, - Tatra steering system (via small LA) with Ackerman geometry, - Independent steering of front and rear axles, - Normal steering mode, - All wheel steering mode, - Crab steering mode - 2 L motors for winches, one for each winch, - Openable doors, - Hidden/flip-up headlights, - Working steering wheel, - Hemi V8 engine with carburetors and blower. BOSS Here you can see door opening mechanism. UNDERDOG SINISTER VICE And here is the chassis. So, which combo do you like the most?

    [MOC] Crossover Vehicle

    Current: Just scroll down, it's not that far! (Just kidding! This will be updated soon!) Hi! I have another WIP car that I am building! I am still not sure what to call it, but it kind of reminds me of the newer Toyota RAV-4. Here is the chassis and part of the front end! (Sorry for bad pic) I borrowed the shaping from my Supercar X for the front panels. It is powered by a buggy motor and a servo. The newer battery box with new batteries and V2 receiver work great with the buggy motor! Here is a shot of the rear suspension: Thanks for viewing! -TechnicRCRacer
  12. Hi, I've built a stupid simple truck. As you might have guessed already, it is largely inspired by iconic Soviet-Russian truck Ural. Driven by two L-motors and steered by a servo, it doesn't have any other motorized functions. The fifth wheel rotates in 2 dimensions and has a simple locking mechanism as seen in a recent 42078 set. However, I doubt it will function properly due to natural tendency to lean backwards under the towing force. Overall, this project is a failure. The initial goal was to built a 6x6 truck with differentials and none-ball-joints suspension. Although the goal was achieved, the front axle turned out to be a complete disaster. First, I had to swap a 6-link for a rather awkward system in order to make the front wheels steer for at least a bit . Second, this truck can't overcome even a tiny obstacle, cause the driving gear in the front begins crackle hysterically. This happens because I don't have the new 6145859 wheel bearing parts, so in order to fit the steering bar with the old ones I had to elevate the axle center 1 stud above the 5x7 frame. And the result simply do not sturdy enough to hold the affecting forces. However, I'm going to figure out a better design later in LDCad. Hopefully this MOC will mark my return to regular building, so I'm looking forward for your comments.
  13. Afte the success of the Jaguar XJR19 Le Mans prototype (of which I will still to the photos of the complete model, and instructions) I decided to do a new WIP. Again it's a model I've prototyped over the last month and will now do the second, hopefully better buildup. And again, I will use a photo of an existing vehicle as my inspiration, but it won't be an exact scale model. I use the photo as inspiration and will deviate where needed for the functions (and it will be needed, because i want a 4-function switch box similar to 8258). It's this truck. It's called Foremost Delta 3 Wheeled Carrier and it seems to come in several configurations, one of which has the crane below. On this picture, it's not finished, because outriggers seem to be missing. Several other pictures of the same model show that it has one set of outriggers near the crane. My other source of inspiration will be set 42070. I want to make something with a similar size, which will be in a way "my own take on that set's theme", i.e. "off-road truck with crane". (That's all I will use from that set). So I'm thinking of something in the range of about 2000 pieces. (In practice though, it will always turn out to be more.) Another thing: the colors will be very different. My first prototype was obediently yellow, but when I arrived at the cabin I wanted to deviate a bit, so I threw some less-used colors in the mix, and went for Dark Turquoise with Black for the cabin, and consequently also for the crane and bed. The chassis will be Dark Gray and for the body I am torn between Yellow and Red (main reason being the colored axles I want to use, for example for the ladders). I will be copying the crane from 8258 (with different colors), because that one seems perfect for the scale and type. But everything else will be different. I will be using Tumbler wheels. The profile is not exact but the shape and size seems fine. Also, currently I have only 4, so I will temporarily be using someting else for the front (interestingly, the Porsche wheels have the same diameter and width). I started with two important modules: The one on the left is the 4-function gearbox and crane base, and the one on the right is the rear axle unit. What I like personally is how a 4-way gearbox and outriggers using the new gear rack pieces introduced in 42043 fit in a pretty compact module. Here's the gearbox unit from below. The dark-gray axle joiner is the motor input. I plan on using my newly acquired L-motor. Here's the rear-axles module: Each axle is mounted on two 1x5 suspension arms and two 1x6 links. These 4 keep the axle in place and nicely horizontal. The free ball-sockets near each wheel will connect to the springs. Also, as you see, with the parts used, doing this part in dark-gray seems impossible... Of course, the 15L beams will be replaced by the chassis. It will be a challenge to get this strong though, because the gearbox module has some gears in the way, so little room to connect things firmly. The functions I want to have: Manual steer and drive (so no RC) Electric crane rotation Electric crane first boom element Electric crane second boom element Electric outrigger horizontal deployment Manual outrigger vertical deployment (similar to many sets) Suspension It's not as impressive as 42070's six electric functions in three modes and four nice large-range outriggers, but instead of that, this will have suspension. Next up will be connecting the two modules, and doing the front axle and steering modules.
  14. I' ve made a scale model of this russian all terrain vehicle. I've tried to make it as detailed as possible. Video: Functions: - 4x4 driveshaft with differentials (XL motor) - Steering: brakes that block wheels on one side of the vehicle. (M motor) - Working differential lock (M motor) - Working LEDs - Tires from 42054 - Openable front and rear hatches and windscreen, working wipers Everything is controlled remotely using SBrick. The drivetrain with differentials and portal axles: The steering mechanism is, I think, more interesting. Wheels on one side of the vehicle may be blocked using the driving ring. Than differentials transmits all the power to wheels on the other side. (that red connector represents driving ring) And the differential lock. The driving ring connects right and left differential outputs. And photos of side without wheels and the underside: Please watch the video to see this machine in action and for more details. I hope you liked this model.
  15. Hello Eurobricks AFOLs, I am Engine and this is my first post here on EB forum. My friend HorcikDesigns told me, some of you here want to know more about my last MOC. My pleassure! Original Vehicle: As some of you noticed, my MOC should be scale model of Ghe-o Rescue. It is a Romanian rescue vehicle designed for extreme terrain, with a capacity of up to 11 people. Dimensions are: 5.2 m length; 2.7 m width (even wider version exists); 2.4 m higth (without rooftop carrier). The weight is 3.2 tons. Under the bonnet, more engine types can be monted, with the most powerful one with 500 hp. Live axles are used for suspension, both equipted by lockable differentials. There are also built-in water tanks for 620 liters for fire extinguishing. Another specialty is the possibility to mount tracks to rear wheels or pneumatic "pillows" on wheels for floating on water. Tires are also special. It is Arctictrans 1300x700-24 (diameter 1300 mm and width 700 mm). The manufacturer shows off an independent test in which they won over Avtoros and Trecol manufacturers. Here you can see several cars built on them. And because the tire diameter and width exactly match the 1:16 scale to the LEGO "Tumbler" tires Ø81.6x44, the scale of the model was decided. So far I do not know any other LEGO cration of Ghe-o Rescue. MOC: The MOC was designed for Kostky.org Trophy Competition, organized by our technic race event guru Peter. And the task was to build a drivable, remote-controlled, off-road vehicle that would be able to travel about 3 km. And at the same time, it should be as beautiful as possible and with design matches to original vehicles. Terrible task. The dimensions of the model are: 332 x 168 x 168 mm (41.5 x 21 x 21 studs), weight 1.2 kg. The drive is permanently 4x4 without differentials. Axles are not sprung. But thanks to the torsionally soft frame of the vehicle, decent axle crossing is achieved (some LEGO trial experience here). Inside, there is a functional winch with a length of 2.5 m. Good lighting is a necessity for the expedition special. The control is provided by sBrick. The propulsion is made by 1 x PF XL motor with a total gear ratio of 1: 1. Schizophrenic steering is provided by the PF Servo. The winch is driven by a PF M motor via a worm gear (8: 1 ratio). Five pairs of PF lights really shine in front of the car. Electrical source is a battery box with 6 AA batteries. The whole MOC is pure LEGO exept of: sBrick receiver, high strength thread as winch rope, threaded cardans and event mandatory stickers. Drive ability: Drivig speed corresponds to a pleasant walk. Off-road capabilities were adequate to the track. Tire traction did not limit offroad capabilities, but a small power of e-motor did. Then the winch becomes useful, that is able to lift the entire weight of the vehicle. And if it was still not enough, the other "competitors" were there to help. A minor issue was the steering. Thanks to the loose in steering mechanism and occasional insensivity in the mobile app, sometimes I sent it out of the way. A major issue was energy consumption. Within 1.5 km, I drained out three sets of batteries (2x alkaline GP Ultra Plus, 1x rechargeable GP 2700). And yet I do not know how to solve it. But most likely it is caused by PF Servo motor, as we disscussed after the event with other partipiciants. ----- Thank you for comments and questions. Pictures are here in my gallery. Original post on Kostky.org.
  16. 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
  17. Hi, This is my latest attempt at building offroad car. Wrangler Trophy by Horcik Designs, on Flickr JEEP Wrangler Expedition by Horcik Designs, on Flickr Introduction and Motivation I built it for the Kostky.org TROPHY, adventurous event and AFOL meeting that is inspired by Camel Trophy series, and was held by Kostky.org (CZ+SK LUG) at 5th August 2017 for the very first time. It was awesome day, and I hope that there will be more. Here is the the official video from the event. There were really great cars there. The car itself The car was built to fit the rules of the competition. That means reserve "fuel" in the car during whole race before refuelling, remote control (no wire connection between truck and controller, S-bricks allowed) and representative appearance. So I decieded to go with the force, and installed two XL motors for the drive, geared down in 3:5 ratio, and two L motors, each for the winch (1:8) and steering (mini LA). I also reduced gearing to the minimum, due to minimal energy-consumption. (I nearly did the whole race to single Li-Po BB) The car is not perfect, it is very heavy (approx. 1500g), so it does not allow to use CV joints in the front axle for smooth wheel rotation. They managed to withstand the race, but in the finish (before the big uphill from the first video) they were strongly damaged, mostly because of big steering angle. Well, I hope that the video will say enough, if you have any questions, feel free to ask me. :) Photos: JEEP Wrangler Expedition by Horcik Designs, on Flickr JEEP Wrangler Expedition by Horcik Designs, on Flickr JEEP Wrangler Expedition by Horcik Designs, on Flickr JEEP Wrangler Expedition by Horcik Designs, on Flickr JEEP Wrangler Expedition by Horcik Designs, on Flickr
  18. Hi everybody! today i wont to show you my new creation - Gaz 34-6x6 soviet truck. This truck is modification of legendary Gaz 66.I'm crazy about 6x6 trucks,thats why I built Gaz 34. So,here it is: As you see,this is not original configuration of Gaz 34.I'm added portal axles(without diffs),bigger wheels and slightly changed the rear suspension.Finally-it is really good trial truck,with great grip on sand,grass (thanks to the wheels from 42054). So,lets look for the technical specifications: -6x6 wheel drive,without any diffs -portal axles -huge offroad wheels -2 buggy motors for drive -1 medium motor fot steering+micro motor(they tern steering wheel in the cabin) -Sbrick -3s li-fe battery(9,9 volts) -Leds lights(headlights) -balanced rear suspension(thats why truck has really good suspension travel) Let see it in action! https://youtu.be/hHDJLmvZ4BA

    [MOC] Jeep Wrangler

    Hello everyone! This is another Jeep which I built while leaving some unfinished projects on the shelf. For three months I have had no time for LEGO mainly because of my nursing job. (Did you see Wolverine taking care of Professor X in the movie "Logan"? I do something like that ) I really needed to take a new step forward for my motivation. Instructions of former two MOCs are still work in progress. I am sorry to keep you waiting. Jeep Wrangler Weight: around 1100g (with hardtop) -2 L motors for propulsion -M motor for steering -Front and rear open differential -Linked pendular suspension without shock absorbers -Openable hood, doors and tailgate with lock -LED for headlights -Detachable body The chassis is not realistic at all. It was new to me to build the suspension without using shocks. It even doesn't have sway bars. Suspension travel is long enough for this scale. It worked fine when driving over small obstacles. But on a steep incline (40+ degrees), it became unstable and tended to roll over sideways. That move was understandable because it had no anti-roll mechanism. I tried to put the battery box close to the center as possible for better weight distribution. Passenger seat was sacrificed for it, but the whole model with hard top is still slightly rear-heavy. Jeep Wrangler is known as one of the most modifiable vehicle on earth. So I made a few options such as 2-piece hardtop, tube doors, bumpers and another color scheme. But the best way is building more realistic chassis for this body. Unfortunately I could not make it this time. Maybe in the future... Building instructions for red version with those options above available at Rebrickable. I hope you will like it!
  20. Good day. This is a trial truck using 1 XL motor for drive, 1 M motor for steering and powered by BuWizz. The drive is powered through a worm gear to 8t gear, creating a powerful 1:8 reduction. It uses model team wheels , they don't have the best perfomance, but it is good enough. For the bodywork I was inspired by ГАЗ-66 (gaz-66), although it isn't an exact copy.

  21. hi everebody! Today i would like to show you my new 4x4 pickup truck. Specifications: dependent suspension portal axles 2 buggy motors for drive(geared 13,8 :1) 1 M motor for steering 107 mm wheels so,here it is and the video available here:
  22. Well, I was not really 100% happy with the buggy I made and in that post I asked for advice on drive axles. Unfortunately as I mostly only have old pieces (pre dark-ages) I could not make most of the suspensions So I tried one that I could use (I originally wanted to make a mini front wheel drive car) and made a mini car with what I could. I'm really proud of what has turned out, the truck looks like a jeep/hummer as is so freaking cute I designed the chassis so that the bodies are interchangeable. I think that a competition where everyone is to make a body for one type of chassis would be really cool, but i'm not famous so it seems far fetched Thanks guys, <forgot to add> The reason this car is a little slow is that my family forced me to purchase rechargeable batteries meaning that the output is 7v not 9v. I would get a buwizz but that is expensive
  23. Hey guys I wanted to test out the unimog suspension but I forgot how it was set up so I tried what i remembered of it into this buggy's rear axle: But I think I somewhat messed up What are the principles for live axles? And on a completely unrelated topic, does anyone have tips to make driven and suspended front wheel drive? Thanks Update: Just took it apart, probably gonna use the advice to make something better.
  24. A model I've been working for a little while, not much to show yet but pictures soon. 6x6 truck with locking rear diffs and 2 central diffs in the 6x6 drive making for a combination of power delivery choices, similar to the drive train of the mercedes amg 6x6. Using tires from 42054 so its, big near half a meter or so now. Rear live axel suspensions front independet fake v 10 soon to be geared in, possinble addition of 4 speed gearbox and 4 xl motors for drive. with fully rc gear and diff lock control and who knows what else?
  25. Hello! My latest MOC is a re-creation of unusual Jeep model. Jeep Mighty FC Concept -Weight: 2125g -2 XL motors for propulsion -Servo motor for steering -M motor for 2 speed gearbox -M motor for locking rear differential -M motor for winch -3 LEDs for front and rear lights -2 SBricks powered by one rechargeable battery box -Portal axles -Openable doors and tailgate -Shallow bed with fold-down sides -Detachable roof -Alternative tube doors The chassis is not realistic, but has decent offroad capability as heavy Lego model. My goal was to make a sturdy and powerful crawler having propulsion motors and gearbox on the center of its chassis. Which means the drivetrain contains two universal joints - weakest points - for transmitting the torque to front and rear live axles. To save U-joints from damaging, I adopted two stage reductions after differential on both axles. The gearbox is similar one to my previous FJ40 Crawler. I doubled the pair of 8T/24T gear for higher durability. High gear is three times faster than low gear. You may wonder why rear ball joint is connected lower than front. That is for avoiding body roll caused by high torque of hard-coupled XL motors. Seeing from the gearbox, the rear output rotates in opposite direction to the front one. So the front and rear axle are equally forced to rotate in opposite direction to each other. Thus the center chassis with heavy body does not easily roll left or right even when climbing steep incline. (...at least on paper. I admit the complete body is a little bit too heavy to prove the theory above.) Steering angle is good, but turning radius is not so good. Because of the lack of center differential, it cannot handle different rotating speed of front and rear axle in tight turning. On slippy surface, like in the video, it can be steered without any problem. Rear differential can be locked instantaneously. The role of 8T gear on top of red changeover part is to make a tiny gap between 16T clutch gear and driving ring in locked position. Thanks to the gap, 16T gear is not pushed against outer structure. That helps to decreasing the friction. Front winch is powered by M motor geared 9:1. I used two pairs of 8T/24T gear instead of worm gear. It is smoother and surprisingly powerful. The hook can be manually pulled out by switching the lever under right seat. The body looks a bit squarish comparing to the real Mighty FC. Maybe I could replicate trapezoidal shape of its cabin. But I thought angled pillars and roll cage would be wobbly. So I decided to build simple yet sturdy. Instead of realistic appearance, I managed to realize easily detachable roof and doors. Although the whole MOC is built for using Unimog tires, Claas tires also fit well. But the maximum articulation of axles would be smaller because bigger tires possibly touch the chassis and fenders. It would be necessary to limit suspension travel or slightly modify the chassis. I hope you will like it! I will make building instruction. But I have to finish the instruction of Pickup first.
