  1. Hey everyone! For the first time Toronto, Canada is going to have a Truck Trial race . This is my WIP topic for my entry - a 6x6 truck based on the Praga trial truck, as seen below: The goals for this model are as follows: Performance prioritized over looks - a bulkier or uglier design that is more robust will be favoured over a cleaner design. The primary goal is the best possible offroad performance Highly robust transmission and steering - I want to make sure that none of the mechanical functions are going to fail under pressure 6x6 drive with diff locks on all 3 axles 2-speed gearbox Winch My plan for this MOC is to reuse many of my successful design ideas from my most recent Unimog U5000, but with a couple of key improvements: Reusable ideas Robust transmission setup - by gearing down the transmission close to the wheels, pressure is reduced on sensitive components such as universal joints and differentials Gearbox - the gearbox design, based on @Sariel's heavy-duty gearbox idea, was very reliable Pneumatic diff lock mechanism - this was also working very well Features needing improvement Steered hub robustness- the steering hubs on the Unimog were too weak Steering strength - the small linear actuator used for steering turned out to be too weak under the weight of the finished model, as @nerdsforprez originally anticipated (if only I had listened ) The first decision I have to make is how to power the model. Although I was happy with the power output of 2 XL motors with BuWizz on the Unimog, this MOC will be even heavier, so I can either gear the motors down further or power it with 4 XL motors and 2 BuWizz (which is the more fun but more expensive option). I also have to decide how I am going to build the robust front axle I want. I'm leaning towards using the LEGO Unimog portal axle hubs. Despite their poor turning radius, they are probably going to be more robust than any custom portal axle I could possibly build, but if anyone disagrees I would love to hear your arguments . As for the steering mechanism itself, I am thinking of either using a large linear actuator, although it will be difficult to fit in the limited space without limiting turning radius, or alternatively, a large rack and pinion with a worm gear setup. I am leaning towards the latter, but this will be a bit more tedious due to the extra gearing to reduce the speed and the fact that I would like to add a clutch mechanism of some kind so as not to break any components. Here is some WIP for the front axle: I am looking to make this my best trial truck yet, so all comments are welcome and appreciated! I'm looking at you @Zerobricks, you said there was room for improvement on the Unimog and you could give me some advice on my next MOC , so please feel free to do so!
  2. This is an expansion, upgrade and update of the Tiger 4 x 4 x 4 The idea was to improve certain aspects of the 4x4 version: 1. The bewel gears were the weak part of the driveline, so the 6x6 uses additional 12:20 gearing after bewel gears, increasing available torque by 67% 2. Adding a second rear axle additonally helps to spread the load while climbing, increasing available overall torque by another 50%, allowing for a total of 2,5x more torque than 4x4. 3. Using defender wheels, and self-built hubs the pivot point is now a stud closer to the steering wheel and steering angle is increased from 18 to 25-30 degrees, removing the need for rear steering. 4. Center section was widened by 2 studs, allowing both gearboxes to be placed in parallel and the steering servo motor low in the center. Total gear reduction has been increased to 1:5 in high gear and 1:15 in low gear. Gear switching mechanism is now faster and more reliable. 5. Suspension is now pendular with a shock absorber in front and tandem axles with shock absorbes in the back. This allows the suspension to smoothly adjust to the terrain at slow speeds without wasting energy compressing the shock absorbers. At high speeds the shock aborbers smooth out the ride. In the picture below you can see the blue 1x7 beams which swing and allow the front suspension to act like pendular: 6. The model now has working fake engine(s) and steering wheel.I'm thinking of adding a hook arm with a winch in the back, so I can use this model to pull others out during trial truck races 7. Number of motors have been reduced by removing rear wheel steering and having one motor for the gearbox, allowing to add aditional functions as before mentioned hook arm. So...that's all about it for now, I'm only missing defender wheels to finish this monster. Yes it's going to be heavier and slower, but I expect it to be even more capable and reliable.
  3. Post your 42114 mods here. Does someone has a fix for the "hanging head" aka weak pivot joint for the front section of the truck?
  4. Hi, I hesitated if I even should post this MOC here since it is so simple but at the end here I am. I created this truck mostly to have some fun outdoors. It has minimal amount of features and its main goal is to drive over not so pleasant terrain, like sand, mud, snow and even quite deep water. And I can do that without fears, that drivetrain will jamm, gears will skip, motors will get wet and at the end I won't have desire to clean all this mess up. I also very like the closing mechanism of "differentials" covers. It is simple, effective, works like a charm and has satisfying click when closing. This Truck is also testing ground for a couple of solutions I wanted to try out, like drive shafts connected to the axles at the angle, steering controlled by rod or way of suspension for both front and rear axles. Nevertheless please enjoy the video, use the instruction and check some details below if you want to know more. Instructions: https://rebrickable.com/mocs/MOC-136120/keymaker/trial-truck-6x6-rc/#details Some details and main functions: dimensions LxWxH: 37,5x13x15cm weight: 1132g 6x6 drive (3xPF L motors) steering (PF servo) suspension on all axles completely secure bottom of the truck with panels easy access to all "differentials" via openable covers Couple of highlights why this truck can be fun to build and to play with: Drivetrain - it is very solid, so you won't hear skipping gears, if wheels aren't spinning, then you either broke some part or stalled motors. It is also super easy to use different gear ratio or different number (1/2/3), type (M/L/XL) or even technology of motors (PF/C+). What is more, removing all electronics takes only couple of minutes and truck is ready to taking the shower to clean all evidence of you off-road madness Construction - it is very rigid and solid, you can lift it up by almost any part of the frame and body Off-Road Design - all gears are protected so you don't have to be afraid that they will jamm due to sand, mud, snow, stones etc. And even if something get inside "differentials", it is super easy to open covers and clean this up. Last but definitely not the least - ability to drive through deep water - UP TO 8CM! It over half of the height of the truck. 8cm of water and your electronics is still safe. Internals of the truck: P.S. I know it is rather ugly, but it brings fun! :)
  5. 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.
  6. 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.
  7. When I got Off Road Buggy set (42124) in my hand and saw new tyres I instantly get idea for new creation. I must make new Tatra truck. The only question it was if would be the 815 model or the new Phoenix. Then I remembered that I made my first version of Tatra Phoenix model 10 years ago and now it is the time to fix the problems of that model... This is my new model of legendary Czech brand of trucks Tatra. The model Phoenix is in trial truck version. This is full RC with Buwizz 2.0 brick and 2 Buwizz motor for drive. These motors make the vehicle very powerful (watch the video). Also the new tires give it good features and appearance. Specifications:-Full independent suspension (front axle hard springs, rear axle soft spring)-Modular desing (chassis, cab, superstructure)-Detailed interior-The door can be opend-The superstructure is not only for the design but also serves to protect the cab from tipping over 360 degree view Instructions are also available: https://rebrickable.com/mocs/MOC-85659/blaz62/tatra-phoenix-6x6-trail-truck/#details
  8. I was planning to build an improved and updated version of my old 6x6 from 2013 when i got an offer for cooperation from Mouldking which gave me an additional motiviation to design this model. I decided to go with a 1:10 scale, which would be perfect for the Unimog tyres. The final model dimensions are 60 x 22 x 24 cm Thanks to the all the amazing work done by fans updating the LDD, I was able to design the model as a modular build made out of a total of over 3100 pieces: A high number of pieces was needed to made this as detailed representation of the real model as possible. Starting under the hood, there is a detailed working V8 engine connected to the 2 drive motors: Inside the cabin there is a working steering wheel connected to the servo motor along with a detailed center console: Rear seats and the console between them can be folded to access the BuWizz bricks from the inside: Or you can simlpy fold down the rear wall inside the bed: The rear suspension and axles have been designed in such a way to maximize the volume of the bed, which is 15 studs wide, 20 studs long and 6 studs deep, making it my biggest truck bed to date: As you can see all the doors, hood and tailgate can be opened. The front doors even feature limiters: Now going from the aesthetics to functionality: The model features a 6x6 drive which can be powered by a pair of RC, Monster or upcoming BuWizz motors. Power is transfered to all the axles via a 2 speed gearbox. Each axle has a 1:12,6 gear ratio, allowing the 3kg heavy model to crawl over larger obstacles with ease. Low gear has a 1:12,6 gear ratiom while the high gear is overdrive, featuring a gear ratio of 1:7,56, allowing for higher speeds. Just like the real vehicle, the model uses live axle suspension with different spring rates. First and second axles use hard shock absorbers while the rear-most axle uses the soft version. Each axle uses a panhard rod with the rear axles uses two for even greater robustness Of course, I can't forget the most important photo: And finally here's a video of the model in action:
  9. Hello, fellow Eurobrickers! I designed this 6x6 truck today as I challenge and I didn't think much about it but It turned out to be a success (in my eyes). I hope you guys like it. The design was inspired by a mix of old offroad 6x6 military trucks. I say it just needs to do the job and it doesn't need to look pretty while doing it. Here is a list of its features: 6x6 drivetrain springless suspension Modular design Remote control Powered by 2L motors Steering by 1M motor Removable tray (all sides can be dropped. Openable bonnet Openable doors 2 speed gearbox Hi-Low gear For more photos please go to our Bricksafe Page here Please go easy on the look it was built in one day, I would love some feedback. Happy Mocking CrazyKreations
  10. I present a little off-road experiment of mine. It's a large-scale model of the Soviet Ural 375D heavy-duty military truck, a truck I've had the pleasure of driving last year. The model's look is somewhat compromised but it achieved the primary goals, which included stress-testing the planetary wheel hubs, the new differential and my 4-speed remotely-controlled sequential transmission. I'm happy to report that none of these components failed and the truck, which weighs 3.94 kg, is able to drive over a 6 cm tall book or climb inclines slightly above 15°. It's not a perfect model, and it's truly sluggish, but oh well. Functions: remotely controlled drive and steering remotely controlled 4-speed transmission (with the lowest speed disabled so I could use a PF Servo as shifter) remotely controlled pneumatical locking of differentials in all three axles 6x6 drive suspension: live axles #1 and #3, pendular axle #2 (for improved chassis rigidity and to maintain ground clearance) switch-operated rear winch opening hood with a V8 piston engine running at constant speed and opening doors and a tiny detail that I really wanted to get done: a see-through grille
  11. Hi all, I'm experimenting with a 6x6 chassis design (3 motors, one powering each axle independently) and I want it to have steering on two axles. Not an engineer but I've Googled a lot of 6x6 designs, but it's not clear to me which arrangement provides a tighter turn radius - front/rear or front/ middle. The front/middle seems most common in military designs (like the Stalwart). But I find my prototype turns pretty well.
  12. I have been searching new MOC subject for some time, as I want a model to be good looking for display; to have enough features but not too complex; to well use of my inventory (major sets part out mostly from 2012 onwards), and to play with my kid reliably. The new PANTHER Aircraft rescue and firefighting (ARFF) vehicle by The Rosenbauer Group has caught my attention. It’s the 4th generation ARFF vehicle launched in mid 2015 and its futuristic appearance, 6x6 chassis, unique sliding doors and feasible color scheme fit my MOC wish list very well. I started from the bodywork by modeling the truck exterior features, for example , roof profile, back exhaust louvers, incline headlights, steep ramp angle at the front and the back, and spent quite some time adjusting the body shape from being too boxy. The design of the chassis is straight forward. Since the real PANTHER is supposed to be a fast rescuing machine, I made good use of the large interior to fit in 3 XL motors to ensure enough power for driving. One motor drive one axle at a time, instead of stacking all three motors in parallel. This will avoid too much toque applying on one single Lego element. Rear axles are modified live axle suspension ‘floating’ within a rigid frame, resulting similar effect as independent suspension. Front axle is simple live axle suspension with steer function. All axles are driven in 1:1 ratio. Similar to the real PANTHER engine location, an inline 6 cylinders fake Volvo engine is seated at the back and is geared up to 2.78:1. By using the rear axles as pivot, weight (battery boxes) is placed at the back to balance the motors weight applying to the front axle. Sides panels at both end can be opened manually for battery box access. It’s challenging to pack the door sliding mechanism under the cabin without interfering the steep ramp angle at the front. The test build is done during the Christmas holiday and the doors slide quite well after a few design attempts and I am quite satisfied with the result. I am still in the process of thinking whether to use a simple swinging turret as the forth function, or a more complex high reach extendable turrets that will require an extra 2 channels and a lot of design effort.
  13. Hello Guys, I recently created this vehicle, for my kids to play (but also for me) - 2x L-motors: one for left and one for right track - skid steering - chassis is without suspension - 6 pairs of PF led lights FLICKR photos:
  14. Hey y'all, First time I'm gonna try to do a WIP page... Been fiddling around with this Kraz 255b MOC by the one and only Ingmar Spijkhoven and figured out what attachment I'll build finally. In short, it's a mini portable bridge (called a TMM-3 or a scissor bridge). Functions of this add on attachment consist of- Actuator for raising and lowering the bridge Winch for deploying and retracting the bridge 2 stabilizers at the end of the truck to... stabilize the truck Propulsion has been swapped from 2 L motors on the sides to 1 one buggy motor under the hood. Now the replica engine can be put on display. The gearbox I really wanted to try part 35188 to make all the functions AND propulsion run on the one motor. Where I guess we can call the "transfer case" is at is right behind the cab, so here's what the result is for now. It was tricky since the tandem axle left no room for fit it in between the chassis rails. The rear shaft will actually hit the bottom of this when compressed all the way. It's as compact as could get it with Studio (kinda a LDD fan). It'll probably need to be reinforced even more, but wanna see how it mates with the buggy motor first. Never built a gearbox before and destroyed many other MOC's with gearboxes so don't have high hopes. Note- all of the motorized attachments will be ran with worm gears, so not to concerned with the gear ratios... buggy motor just gonna make everything super fast anyways with a Buwizz. Where buggy motor is planning to be in the future a bit more securely. Just seeing how a gearbox could be placed and how high it'll be. Part 87408 is now mounted securely below the motor with two 24t gears feeding it above (will get a shot of it soon). Getting the motor to fit underneath the hood was very miserable. Couldn't use a servo anymore since the buggy motor is so low it'll interrupt the travel of the front axle. (yes the fenders are mounted backwards when rebuilt...) Ordered the parts for the gearbox and will update once they come in. Planned order of the build- Gearbox Wheels Test drive Stabilizers Building the frame/chassis of the TMM winch Scissor bridge Survive the misery
  15. I decided to UP the things with my take on the 8081 modification contest. Here's what I came up with: Driven and steered front axle with homeage to the original design Tandem live rear axles working on a simillar prnicipal as the front axle Differential lock Two speed gearbox Working steering wheel You can see a sneak peek of the progress made in LDD:
  16. For Mission to Mars I decidd to build more of a classical machine - a six wheeled rover. I was heavily inspired by the upcoming Mars 2020 mission (https://en.wikipedia.org/wiki/Mars_2020) and wanted to integrate a drone inside the model. First thing to build were the foldable Rocker-bogie suspension arms, which is unfolded with pneumatics Each bogie featurs a steerable front wheel which is steered using a worm gear mated to a small turntable. Drive power is carried through the turntable to the front wheel. The rear wheels are on their own bogie and are driven by a combiantion of Cv and universal joints: A longitudinal differntial is used on each drivetrain which allows for the speed differences between front and rear wheels when steering. Differential is especially required when steering at 90 degree steering angle, since the rear wheels do not turn at all. A driven differential is used to level the both sides of the suspension arms: Differential allows for the movement of suspension and keeps the body leveled. A single M motor is used to adjust the leveling angle via a worm gear. Suspension in action: In order to unfold the rover, a pneumatic compressor was installed near the front of the body: The same compressor also powers 4 small pneumatic cylinders which open up the tops sides of the rover: A large actuator lifts the base of the 3D camera (placeholder for Wi-Fi camera) on the top and reveals the propeller "drone" inside the rover: Since most rovers include some kind of an arm to dig and check samples, I decided to equip mine with claws. They are able to pick up and lift with the use of a single M motor: And finally the rover can launch the propeller drone using an RC motor powered by BuWizz: Here is the final wrap up of the features and characterisics: 38 x 25 x 15 cm when folded 41 x 25 x 57 cm when unfolded Weighs 1800 grams Powered by 5M, 2L and one RC motor Controlled by 2 BuWizzes Independent all wheel drive with longitudinal differentials Rocker-bogie suspension Pneumatic unfolding Raisable 3D camera arm - placeholder for a WiFi camera Leveling mechanism Drone launcher Working claws Unlimited steering angle And a quick video of the rover in action:
  17. Hello dear friends! Please let us (yes, today - we are both with ADCchannel are the authors) introduce the latest MOC - today this is Mercedes-Benz G-class 6X6 Trial edition. This truck (definitely it is!) is our common project. I was always dreaming of creating my own implementation of this greatest version of legendary Gelandewagen. I build the body with pleasure and know that ADCchannel riched senior skills in building chassis for truck trial, so I offered hiw some kind of collaboration. Luckily, he immediately agreed. The main difficulty was that we are living in different cities, but not far from. So, couple of month were spent truck is ready. To be honest body itself is absolutely new. From my previous G class Mansory edition I took only front view and side doors. Roof, interior, body frame is completely new. Mandatory point was to create easily removable body. So, you can split body from frame removing only six axles (easy to remove). Some description, though :) This monster is propelled by 3 XL motors - one per each axle. M motor for steering and we decide to power truck bu Buwizz. But it's ready to use regular Lego IR receivers. Suspension has 3 portal axles like original Mercedes. We use 7 Claas tires (actually 6 + 1 third party). Everything what can be opened - is openable - hood, doors, trunk. Unfortunately there were no room for any V8 engine due to front suspension construction. First purpose was to build truck suitable for trial. Here are the two different(!) videos. Feel free to watch and comment. Any critics would be highly appreciated. Dimensions: - Wide - 25 studs, - Lengh - 72 studs Here are some photos from bricksafe page: https://www.bricksafe.com/pages/Aleh/mercedes-benz-g-class-6x6 Pictures will be uploaded in a couple of hours. Some technical issues for now.
  18. Hello everybody, I present to you another "ancient" MOC of mine - built in May 2016 and only now I finally managed to make a presentation of it - The Logging Truck: At first it was supposed to be a Trial Truck, but as it grew to heavy, especially due to "model team-ish" cabin, I decided to make it more easy going. It doesn't represent any particular model, nor is it scaled or anything... It's driven by a PF XL motor and steered by a PF M motor. It has full suspension, detailed cabin interior and engine compartment. Oh, and I have to admit it is heavilly inspired by Ingmar Spijkhoven's work (2LegoOrNot2Lego). I'll let the photos do the talking... The position of the trailer trolley can be adjusted between the two yellow stops - the main beam slides through the trolley and is held in place by springs and rubber 2L connectors. While the truck is fully suspended, the trailer uses a kind of pendular linkage between both axles. The cabin has detailed interior... ...and so does the engine bay - totaly imaginatory - without any knowledge or research of the real truck engines . I guess under skirt shot is in order... I really like how the front axle turned out, the ackermann is almost to much. Here's another pair of photos to finish it off and a short video of course... I hope you like it and thanks for comment. Please find bigger photos here. Best regards, Miha
  19. 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.
  20. Normally I would prefer building something really sturdy, as a result these models are always heavy and have a lot of redundant parts. This time I tried something new. Presenting my new MOC: a lightweight 6x6 pickup truck. This model is based on the Mercedes G63 AMG 6x6. It has a two-door cabin instead of the original four-door one, just to meet the definition of “Compact” in its name. It weights 1.2kg, and has around 1350 parts. I’m pretty satisfied with it given the fact that it’s a fully functional 6x6. How to make a lightweight yet reliable frame is a challenge. My solution is to have a unibody design, like most family sedans, instead of a body-on-frame structure, which commonly seen on off-road trucks. This means pillars need to help with sharing the load. The whole drivetrain is simple. All axles are live axles. Rear axles have multi-link suspensions. How to position those links is a big deal, misplacement will probably introduce unwanted wobbles. Considering the weakness of the universal joint, I didn’t put to much gear reduction into it, on the other hand, it has a relatively decent speed. Field test: With no diff lock, sometimes it struggles on rocks. But most of the time it can deal with less bumpy roads. More details: I will create instructions in a while. Enjoy.
  21. Hey guys! I'm going to try something I haven't so far - a WIP thread for my new tatra 6x6 truck. I'd love to hear all the advice you guys have along the way! The idea is to make a pretty small truck with servo steering and two L-motors, one powering each side to eliminate the need for differentials. Each half axle will be suspended by its own spring. I've already come up with a front axle that I'm happy with. It's solid, good ground clearance, good steering precision despite smaller steering radius, and it's just the right side. If it's not too tall, which I'll have to figure out, the plan is to stick the servo motor vertically right onto the 8-tooth gear, which will give it excellent precision. Another gearing, if I put the servo on its side, would multiply play in the steering system. What do you guys think?

  22. After some month of building I like to show you my latest MOC: A Mercedes Zetros 6x6 truck. It is a ~ 1:13,5 scale model of the Mercedes Zetros 2733. All functions are Full RC. It is 69 cm long, 21 cm wide and has a height of 27,5 cm. The weight is 4553 g. As battery I use the BuWizz. The Zetros is remote controlled by 4 Sbricks via iPhone. Functions and used parts: Propulsion: 4 Lego Technic Buggy Motor Steering: 1 Lego PF Servo Diff Locks (front / rear axles + central lock): 1 Lego PF Servo 4 Lego Pneumatic V1 + V2 1x5 (Automatic) Compressor: 1 Lego PF L-Motor 4 Lego Pneumatic Pump (V2) Winch: 1 Lego PF L-Motor Telescope Crane: 1 Lego PF M-Motor 3 Lego PF Servo 3 Lego Pneumatic V2 Cylinder 2x11 2 Lego Pneumatic V2 Cylinder 1x11 Outriggers: 1 Lego PF Servo 1 Lego PF M-Motor 2 Lego Pneumatic V2 Cylinder 2x11 Lights: 10 pairs Lego PF LED plus several Lego extension wires Some more highlights: Full independent Multi link live axle suspension Portal Axes Planetary Gears Working head lights, rear lights and flood lights Working turn signals and warning lights [/url Edit: I nearly forgot some special picture pair ;) [/url] Second edit: I corrected the scale which I'd miscalculated.
  23. 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
  24. Tatra 815 UDS 114! This is probably the most interesting type of excavator-truck I've ever seen, so I decided to build it on my existing 815 chassis! Here's the video for the chassis, but with a dumper: Thanks for watching! BrickbyBrick
  25. I got this idea a while ago, when I first got Sbricks. Why not make modular, expendable system of axles and chassis pieces in order to create a system for offroad truck construction. Here is what I sketched up in LDD. First we have a basic axle. It uses 2 XL motors for drive, independet suspension and steering with servo Because we need a minimum of 2 axles, I designed a double chassis holder with two battery boxes: If we combine 2 axles with the double battery holder, we get the most basic configuration, a 4x4x4: In order to expand on the system I designed a single battery chassis extension: Finally we can combine the three basic modules into a 6x6x6: Or even a 10x10x10: In theory there is no limit how far you can go, but I think anything over 12x12 might cause too much strain on the chassis. Important details: - Axles are designed for Claas wheels, which are not in LDD, hence the wheels above may look small - Each axle can use any kind of a combiantion of number of springs and hardnesses for best flexibility and weight support - Each axle is meant to also house and S brick, which allows you fine steering angle control in order to support any kind of configuration or steering mode (only front, only rear, all wheel steering, crab mode) - For now this is still a concept, so I will relase the LDD file once I build, test and polish the concept
