  1. Hello everyone, This is Evan here with my first Eurobricks topic! I decided as soon as I obtained the 42122 Technic Jeep Rubicon set to massively upgrade it (similar to what y'all did here, here, and here). The only difference is that I am starting from scratch and rebuilding the whole vehicle based on the original set to not only be more functionally proficient (which is the focus of this venture), but also to look a little bit more aesthetically appealing;) As per my preference, I will start with the functionality. Since everyone else put the differentials in the axles, I decided at first to take a different route and take them out of the axles and instead put them in the cabin. See the following pictures of the front axle: Maybe this idea will work for you in a different project, but I quickly found out that it would not work for my MOC after making a few test chassis assemblies. By displacing the differentials from the axles to the center of the vehicle greatly increases the area that the drivetrain takes up in the cabin of the Jeep, so I decided to go with the differentials in the axles. As you can already see, I went with the CV joints for the steering drive connections just like Zerobricks did. However, I decided to go with the mustang wheels to center the steering pivot more. Also, I added Ackerman geometry to the steering system out of necessity. See the following pictures: I used this piece to connect the steering gear to the axle frame with the gear that drives the differential. It works quite well. Also, the steering rack is held in place by the actual "U" technic frame. Please let me know what you think of it so far, I will continue to update it until I finish it!
  2. Hi, guys! I know that, there is February yet and we're before March release, but let's start new topic! So, at first I want to say that 2023 wave is amazing. New brand, new mudguards, new windscreens! Whoah!

What cars would you like to see? Show your speculation/wishlist.
  3. Hello Eurobricks community! Let me introduce my latest MOC - Hummer H1 out of Lego pieces. It has approx 3800 parts, incl 7 Motors. Functions are: - Independent suspension of all wheels - 3 RC differentials like in the real model - 8 Cylinder engine - module build - easy removable hood and body. - 4 L motors for drive- Servo for steering- M motor for the winch- L Motor for diffs lock VIDEO: All photos: https://bricksafe.com/pages/Aleh/mercedes_770/hummer_instructions To start this model I was inspired of two things: 1) This video 2) Humvee from CADA Most wanted render: Building instructions are available: https://rebrickable.com/mocs/MOC-174585/OleJka/hummer-h1/#details
  4. Many people have been asking me for a simple, easy-to build and most importantly cheap Off-Roader. When I started this project, I've set myself the following guidelines: Use a single BuWizz 3.0 and "only" 2 BuWIzz drive motors Implement a 2 speed gearbox Maximize the ground clearance by using a pendular axle (this way the independent suspension doesn't have to loose ground clearance when going over obstacles) The model has to be built from under 500 parts All the parts have to be standard and in current production Keep the number of different parts as low as possible Use color coding to simplify the building process Design the model so that it can easily be modified by other builders Create proper building instructions And this is what I came up with in the end: I managed to successfully realize the all the planned functionality, features and more: All wheel drive 2 speed gearbox Pendular front axle Independent suspension on all wheels Openable doors for easy acces to the charging port Interior with seats and a steering wheel The dimensions and specs are as following: Built out of ~460 parts 27 x 20 x 13 cm ~ 850 grams Top speed of 7 km/h As usual there's a video showcasing the model in more detail: But just building the model and recording the video was only half the story. I also taught myself how to create the building instructions using the Studio which can be found here: https://bricksafe.com/pages/Zblj/simple-off-roader Since these are my first such instructions, they may not be ideal... So in a case of any issues, confustion, or such I also uploaded the .IO and .LXF files which can be found in the corresponding Bricksafe folder: https://bricksafe.com/pages/Zblj/simple-off-roader All in all this was a great learning experience, I'm always happy to learn a new skill and being able to create my own instructions sure is a good skill to have as a LEGO builder. To conclude; using this as a base, I wonder what kind of tweaks, improvements and crazy mods other builders will come up with!
  5. Wasn`t sure if i had to post this on the old thread or to make a new one, but I decided to be safe. Anyway, I recreated Jantayg`s buggy made for the BuWizz 2018 ”Fast car competition”, but, being a recreation not a copy, differs in some manners, such as the way the front frame is attached to the main chassis. This MOC has 1x buggy motor and 1x servo-motor, pneumatic shock absorbers, a good suspension travel and a space more than enough for the battery/ electronics but sticks to around 700g with 1x battery. You can find the digital construction file and the part lists for the other paint-jobs on Rebrickable Thanks to the original creator that accepted this recreation to be made public!
  6. 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.
  7. Hi, I would like to present my newest creation – off-road truck Gaz 66. It is my interpretation of small, old and very popular truck, which has a lot of off-road capability. Someone can ask why next similar small scale off road truck? I would say I like this type of vehicles, the scale and challenges they bring. And with every build I try to test something new, which I wasn't try before. Here the main goal was to go below standard for those wheels width of the model - 15 studs and prepare narrower axles than standard - 11 studs ones. Which I did. Gaz 66 has 13 studs width body with 9 studs (from rim to rim) front axle - stereed and driven. Thanks to that size of the body is more proportional to used wheels. And you can also use tractor tires provided with cargo for even better effect (you can see such modification in real Gaz 66 on one of polish off-road YT channel - LINK). I also tried to add as many details related to real truck as possible, in this scale, I hope there are here some fan of original Gaz 66 and they will recognise some elements I added. Below you can find video and list of features and details. Enjoy. Instructions: LINK General details scale: 1:20 dimensions LxWxH: 30x10,5x12,5cm weight: 946g Features: RC front axle steering (C+ L motor) RC 4x4 drive (C+ L motor) RC winch with place to lock the hook (C+ L motor) 4-link live axle suspension for all 4 wheels three studs ground clearance (with "KrAZ" tires) openable doors and easy access to spare tire working V8 engine with fan located in cabin, plus grill via which working engine can be watched detailed two seats cabin powered by Buwizz 3.0 but also prepared to be powered by standard C+ Hub can operate with "KrAZ" tires included in cargo Photos: LINK My Gaz 66 is powered by Buwizz 3.0, but there is no problem to use standard C+ Lego battery box: Internals of the MOC, so drivetrain connected with V8 engine, steering and the winch:
  8. Here's a model I actually completed a year ago in order to be unveiled in time for the BuWizz picnic back in 2021, but we all know how things went... Anyway since the picnic did happen last weekend, I decided to unveil my most powerful offroader. The basic design is based on the Wildcat 4x4, but this version adds more power, a 2 speed gearbox and a third axle to the formula. As with the older version, each axle has independent suspension, plus the entire axle can pivot or swing, effectively giving this model double suspension setup. Indepedent suspension is great at absorbing small bumps when driving quickly, while the axles pivot along the terrain when crawling. The driveline was quite a challenge. In order to transmit the power from 12 motors to the wheels, each wheel ended up having it's own dedicated 2 speed-gearbox. The final driveline is extremely compact and efficient, with only 3 gears engaged at any given time. There are also no differentials or perpendicular drives, so nothing that can break or skip. Each gearbox is actuated by a PU M motor using worm gears, which prevent any unwanted skipping out of the gear. This way each wheel is powered by 2 BuWizz motors via a dedicated gearbox: The following gif shows how the front axle is designed along with the whole model: Here you can wee, how the front axle tilts in order to adjust to the terrain: The rear axles are made in the same way as the front axles, minus the steering. Rear axles are also designed to work in tandem, when one goes up, the other goes down. When one tilts left, the other tilts right. This way the rear suspension is extremely flexible: And finally here are some specs of this beast: Length: 52 cm Width: 26 cm Height: 20 cm Weight: 2,5 kg Top speed: 15 km/h (rounded up) To complete the presentation, here's a video of the model in action, a big thanks out to @braker23, @Sariel and @kbalage for the footage. Final thoughts... this is my most potent offroader to date. The sheer amount of power, torque and speed is hard to wrap your mind around for a model made entirely of small plastic pieces. Having said that, I think there are still few areas to improve: Tendency of the front wheels to fall off at hard bumps - A lighter version would help to reduce stress on the hubs and wheels. Could use a higher steering angle - Would have to find a way to integrate steering racks inside the transaxles. Protection againt depbees and dirt entering the drivelines - Something that would also not reduce the ground clearance, tiles might work.
  9. Hi, I present my newest creation – off-road truck KrAZ 255 version 2.0. This is successor of my first public MOC – KrAZ 255 to which free instruction are available here. The goal in version 2.0 was to improve basically every aspect of predecessor and to pay respect to this awesome off-road truck. And as usual, most of the features are based on truck Tayga 6455B available in game Snowrunner. This truck is also the next part of my Snowrunner series started with Chevrolet CK1500. On the video below you can check what details and functions I was able to put into this MOC and how KrAZ 255 v2.0 deals with off-road terrain and against obstacles. Extensive list of features, details and interesting facts about this creation you can find below the video. Enjoy! Instructions: LINK General details: scale: 1:23 dimensions LxWxH: 42,5x13x16,5cm weight: 1525g Features: 1. RC front axle steering (C+ L motor) positive caster (click) Ackermann geometry almost perfect pivot point (click) PF servo friendly - 180 degrees of movement for steering input 2. RC 6x6 drive (2 x C+ L motor) independent drive input for each front wheel (click) (for this idea I would like to thank @Fluwoeb and this topic, this is because of you! ) rear wheels driven by two independent inputs (one for 2 left wheels and one for 2 right wheels) (click) front wheels driven by one differential and rear wheels driven by second differential (click) both differentials coupled together to harness power of two C+ L motors both differentials coupled with lock mechanisms (click), controlled separately and manually from the cabin (click) and equipped with visual color indicator of diff lock on/off status located behind the cabin (click) power train equipped with new big CV joints - cardans and old CV joints limited in drive of the front axle and completely removed from drive of rear axles 3. RC winch with place to lock the hook (C+ L motor) 4. RC front and rear lights (Lego LEDs) 5. suspension for all 6 wheels (click) front wheels on live axle suspension with shock absorbers (click) and a big range of movement (click) rear wheels located on independently oscillating arms with rubber suppressors controlling the movement (click) rear suspension without shock absorbers - no side leaning and no bending under the load (click) 6. three studs ground clearance (click) 7. bottom of the truck armored with panels to secure crucial mechanisms and improve dealing with obstacles (click, click) 8. two hooks for connecting trailers, front and rear one, both equipped with lock/unlock mechanisms 9. openable doors, hood, tool box, first aid kit, sideboard bed with separately openable sides, each one with two locks 10. working V8 engine with fan which can be easily removed “for maintenance, repairment or for swap” located in detailed engine bay with a grill via which working engine can be watched (click) 11. detailed two seats cabin with openable and usable glove box (click) 12. working steering wheel 13. modular construction (axles, cabin, additions can be easily disconnected) 14. powered by Buwizz 3.0 but also prepared to be powered by standard C+ Hub (click) 15. prepared to be built also with PF motors and PF servo without significant changes and to be powered by Buwizz 2.0 (click) or even standard PF Battery box with IR receivers (click) 16. "disk brakes" in front (click) and rear wheels and many others small details (click, click, click) 17. equipped with many additions from the game Snowrunner, like bull guard, exterior roll cage, roof rack with fuel canisters and spare tire, double snorkel, sun protector (click) Interesting facts, designing decisions and details: driveshafts for front axle are connected in a way that the longer, more “smooth” CV joint part are connected closer to front axle, so lower to the ground, which corresponds with the idea to prepare bottom of the frame smooth and resistance to sticking out objects which can immobilize the truck (click) most of the motors are placed symmetrically at the center of the truck, which is good for weight distribution, but Buwizz unit is localized off centered, closer to the left side of vehicle. To balance that, motor from winch is placed also off centered, but closer to the right side of truck (click) all wheels can harness power from both C+ L motors, as they are coupled, but rear axles, which in general generate more load for motor, are connected closer to the right motor, that is why V8 engine is connected closer to the left motor, which is connected closer to front axle, as the front axle generates less load than rear ones (click) additionally output for V8 engine has the same speed as motor output - which is higher than rest of the drivetrain - for better visual and sound effect (click) there is a „biscuit connector” placed in rear wall of the cabin to increase ways of location and connection and types of power source which can be used to power up the truck (click) to avoid widening the whole truck, only hinges for sides of sideboard bed are located outside of the sideboard bed to allow opening sides to vertical position, which makes loading the cargo easier (click) positive caster present in front axle has (apart from being next feature adapted from real cars, apart from dealing with not very high tolerance of Lego parts, which causes negative caster and apart from being the force which steers front wheels strait when driving forward) a function of forcing front wheels to stay on axles when driving forward (I think this is the answer you were looking for @AutoBacon in this post ) and many more details you will discover, if you decide to build my truck I would also like to thank @nico71 for his great video series related to Western Star 6900 Twinsteer. It helped me to prepare more realistic grill, hood, roof elements and I believe overall better body of the KrAZ than in my first version of this truck. Thank you! Attention! Two C+ L motors with decreased speed 3 times, so with torque increased 3 times, generate a lot of force which needs to be handled by rather advanced drivetrain. That is why there is a risk for 12T gears to skip or even be destroyed if wheels come across too much resistance due to very rough terrain. Please keep this in mind and happy off-roading! Photos: (click) Here you can see the original KrAZ-255 (1211 parts, 991 grams), the new KrAZ-255 v2.0 in standard configuration (1632 parts, 1220 grams) and the fully equipped and ready for everything version of KrAZ-255 v2.0 (2091 parts, 1525 grams): Internals of the MOC, so drivetrain with differentials and diff locks connected with V8 engine, steering with working steering wheel and the winch I hope you like it, if you have some comments or question, please ask. I will happy to answer.
  10. 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.
  11. Hello! This creation took quite long to make, but here it is - MAZ 5316 scalemodel. It has several functions and features: - Driving by buggy motor, 4WD (gear ratio is about 63/5) - Steering by servo motor - Remotely controlled differential lock using pneumatics. For the pump I took inspiration from the Sariel's one. (Single L motor) - Working headlights and taillights - Tilting cab with a fake decorative engine underneath it - Openable doors with rubber band locks - Easy access to the power unit (BuWizz 2.0) - Working suspension on all axles (Live axle suspension) - Custom stickers and other details Overall, the model turned out to be a pretty good off-roader, though it weighs over 2kg. Snow made it harder for the electronics, but the performance was still nice. Also, I'd change the tires in case of driving it on snow. :D Dimensions are very similar to 42129, but the scale is bigger. The main problem of this model is that the pneumatics work inconsistently because of the length of the tubes. Also, steering angle is a bit too wide. 3D model is in process right now, so there is a very slight chance of me starting to make the instructions for it. Video link: Photos: Thank you!
  12. 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!
  13. 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) having two separate drive trains with equal torque while 2) preserving the advantage of having an open distribution for 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.
  14. Hi, Here is my take on rock crawlers – I present to you an unstoppable and fully customizable rock crawler: „Hornet”! I called it unstoppable and fully customizable not without a reason. You can find out why in the video and in extensive list of features, details and links below the video. Instructions can be found HERE, they are free of charge, I hope many of you will be able to build it and have fun playing with it outdoors as I did. Without further talk, please enjoy the video! Details and main functions: • dimensions LxWxH: 36x22.5x19.5 cm • weight: 1.55 kg • 4x4 drive (3xL motors) • steering (M motor) • live axle suspension, front and rear • openable doors • easy removing the whole body with locks hidden in bumpers • it fits Lego Technic Figure Configuration options: 1. Drive and steering • Power version: 3xL PF motors for drive and M PF motor for steering front axle • Agile version: 2xL PF motors for drive and 2xM PF motors for steering on both axles 2. Body • „Hornet” – default body, more build-up, with opening doors • „Red Ant” – alternative body, more open one, 25% lighter than „Hornet” body 3. Suspension • Four independent, clearly visible mounting points available for each shock absorber • Multiple mounting points allow to configure four parameters of the suspension and the whole MOC: - suspension stiffness (from soft to hard) - suspension travel (from long to short) - body height (from low to high) - body style (from rock crawler to monster truck) • suspension can use both long and short shock absorbers Other features (which you may or may not spot on the video): • both bodies are equipped with two seat simple interior with steering wheel and some minor details • both available bodies are prepared in a way to avoid visibility of blue pins • frame is also prepared in a way to avoid blue pins • blue pins in frame are used mostly to high light mounting points for suspension and point out the front of the frame • frame prepared to be allow easy pairing with any new bodies • frame is equipped with simple cable management to avoid damaging motor cables during off-roading • changing connections of shock absorbers to the frame is fast and easy • MOC can be easy carry on both via body or accessable handle at the bottom of the frame • center of the mass is located at the center of the MOC • center of the mass is located low, most of the weight is present in axles • drive doesn't use differentials to maximize off-road capabilities • both axles are secured with panels to protect axles and drivetrain against any dangerous objects (grass, rocks, etc) • high ground clearance for both axles even with using planetary hubs • L motors are connected to planetary hubs without any reduction – this provides both speed and necessary torque • approach angle is 90 degrees, front and rear More photos you can find HERE
  15. RC Rock crawler. Features AWD drive without differentials using 69730 "Large angular position motor"(As it has realy good torque), Steered by L-motor, and springless suspension (concept by superkoala). Lack of differentials gives nice off-road perfomance, but the crawler has big steering radius due to that.42114 C-model.

  16. 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! :)
  17. 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;)
  18. 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
  19. 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.
  20. 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.
  21. 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!
  22. 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.
  23. 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.
  24. 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 :)
