    [WIP] Fox 8x8 V2

    I think it's time to update and rebuild the legend.. Differences between the old and the new model: Because the model will be powered by 3x BuWizz instead of 4 AA battery boxes, it will be at least a kilogam lighter. Independent suspension will be changed to a live axle suspended pendular type. This will allow for much more movement when going offroad and more even weight distribution on the axles. Gear ratio will be changed from 1:3 to 1:1,677 due to the increased power of the motors, decreased weight and improved suspension - making the model 80% faster. NO MORE U JOINTS. Since no U joint, or CV can withstand the torque of an XL motor powered by BuWizz, the motors are now directly mounted on the hubs and steer with the wheels. Because there are no U joints the axle can be narrower by 4 studs, but I had to sacrifice a stud of ground clearance comapared to the old one. Servo steering - steering is now updated with 2 servo motors, each in their own axle. Front-most axle's steering angle is 25 degrees. Rear axles no longer need steering due to... Differential steering - since all motors can be individually controlled, the BuWizz's app allows for automatic correction of motor speeds when steering. This means the model can steer even tighter by reducing the speed of the inner motors when steering. Improved wheel mounting points using parts 24122 - the torque is now sent directly to the inside of the wheels without having to use 24 tooth gears and pins. I ordered the missing components and will send photos of the build as it progresses. For the bodywork I am thinking about a red cabine, but not sure which style - high and flat, or low which stick out in front further. Additional functions will be a winch in the front and possibly a crane arm in the back - I will decide on that after I see how it performs.
  2. Good people of Eurobricks, let me give you my first take on the planetary hubs: Please excuse me for the lenght of the video, it's meant to show the developement stage by stage. I had big expectations towards the new hubs, since they've been announced. I realised, these hubs will solve the problem of the stress on drivetrains, yet will raise a new challenge. Due to the increased torque on the wheels, the frame (chassis) and the bracing of the suspension will be the new weak link. A wanted to have a finalized rig to the date of the release of the hubs. The backbone of the design came from a five years old chassis concept, it was a non motorized chassis: To mimic the geometry of the new hub, I've used the old ones with some extension, so it can be easily swapped, when time comes: The concept of the chassis came together quite well, thanks to using techniques well practiced in my early years. But there was still a long time till the release of the new hubs. Driven by curiosity, I've planted two PF XL motors in the middle of the chassis, making them drive two axles each. One for the front axles, one for the rear ones. No additional gearing has been added, the motors were connected straight to the differentials. Of course it had to be tested, hat's the part around one minute into the video: https://youtu.be/PGQpUrOS-NQ?t=59 Came with a surprisingly satisfying result, despite the usage of the old cv's and hubs, yet it was understandably far from being a "crawler" it meant to be. Also at this point I was short of claas tyres, so I've used some similar size rc tyres on the front 4. Got the tyres eventually, still a lot of time till the hubs coming though. As the final design was gonna use 4 buggy motors, time came to make the change: Same principals, like with the XL motors: No gearing added (slow output used), 2 motors drive the front, other 2 for the rear axles. Now feeding that much buggy motors would require 4 buwizzes. Or one well sized rc lipo that can comfortably supply 2 sbricks. 4 buwizzes cost about 400-450 pounds, while the lipo comes for 30 pounds. Any question? At this stage (still no new hubs) it was an obvious, yet pretty crazy idea to hit the tarmac. So I did. That's what you see at 2:16 in the video: https://youtu.be/PGQpUrOS-NQ?t=136 I had a lot of trouble that day with the bluetooth connection, brought a head on crash int o a container. It was heart-, but no plastic breaking. Finally the hubs came by the post and the picture got full. I've also planted another servo for steering (2 in total now) Indoor durability test at 3:27 https://youtu.be/PGQpUrOS-NQ?t=207 Climbing test (60 degrees) at 4:18 https://youtu.be/PGQpUrOS-NQ?t=257 Hereby I apologize for the dark enviroment at this recording Peek on the suspension at 3:12 https://youtu.be/PGQpUrOS-NQ?t=191 Lego should not be used outdoors... ahm, okay... Outdoor test from 4:55 in the video. https://youtu.be/PGQpUrOS-NQ?t=295 I came to the verdict, that the new hubs worth their money. In a usage that abusive, you see in the video the hub-cv connection definitelly require some lubrication. I've been using silicone oil and no downside appeared so far. Here is the difference it makes: That's it so far, a little spoiler at the end of the video. Hope it's gonna catch some expert eyes...
  3. Hello everyone. This is my second Tatra model.Comparing to previous Tatra 813 Trial Truck built in 2014, it is bigger, heavier and a little bit faster. Weight: 3810g Length: 62.4cm Width: 24cm Height: 25cm -Powered by 2 SBricks -6 L motors for propulsion -2 M motors for steering -M motor for 2 speed gearbox -Working steering wheel and V12 engine -Openable doors, front grill and roof hatch The model was specifically inspired by a unique truck of Jansa Team participating at real truck trial events. I tried to replicate overall look as possible without using any stickers. The cabin became one stud longer than it should be. Also using many system parts was somewhat compromising as a Technic builder. This time I omitted offset axles because symmetrical structure was more robust and efficient. Each side of half axles are independently driven via two parallel drive shafts. That enables slightly smoother turning than previous one adopted single drive shaft. Body parts are removable by pulling out both seats and two 5.5L axles behind the rear bed. When I completed the chassis early in 2018, it never came to my mind that LEGO would officially release "game changing" planetary wheel hub. Admittedly those bulky half axles using portal hub look outdated in 2019. The core of chassis contains bunch of L motors which I called 'Six Pack Abs'. The gearbox is simple yet packed 16 gears into tiny space between L motors. Although suspension mechanism is not like real Tatra, pairs of swing half axles move like real one. That realizes good off-road capability. The steering angle of 1st axle is twice as 2nd axle. Two hard-coupled M motors move 13L gear rack via dual pinion gears. For more powerful steering, I did not use white clutch gears. Consequently geared down motors keep rotating and make clicking noise when gear rack reaches end position. After all, this MOC ended up to be just a big truck driven by old technology. (Strangely it sounds like aged Tatra 813 in modern truck trial events...) Still I am happy with the result and sharing another massive 8x8 model. If you like it, feel free to put colorful stickers on it, make alternate cabin design or build more accurate chassis with new hub parts. Building instructions available on Rebrickable.
  4. 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!
  5. Dear friends! Finally, I started to clean out my MOC closet, which has been gradually filling up the last two years and somehow, I couldn't get myself to empty it. The first of more-to-come skeletons to fall out of it is this TATRA T813 KOLOS in truck trial version, that I have built almost a year ago for our LUG’s annual 14th truck trial race “KockeTerenci”. I got inspired by this little canary on steroids: This is my biggest truck so far, that is actually capable of tackling some terrain. The dimensions are as follows: l / w / h = 65 cm / 19 cm / 25 cm or 81 / 24 / 31 studs. It is a bit to narrow for my liking, but one of our TT race rules states, that gates on track are 30 studs wide, so I went for a fitter width. Truck weighs slim 3,3 kg with 2 AAA battery boxes, with Buwizz a little less. It is a bit front heavy as the cabin weighs more than 0,35 kg+ the steering mechanism protrudes a bit into the cabin. Some photos of exterior before further babbling… I tried both PF and Buwizz for power, which one did better is obvious… I hereby thank @imurvai for BrickController application – it was a pure joy using it. Truck features 8x8 drive with typical TATRA suspension and single drive shaft where left and right half axles are misaligned for half a stud, similar as IRL. Fatso is driven by two PF XL motors that are hard-coupled on a two-speed gearbox, which is a modification Sariel’s linear heavy-duty transmission and is placed between the 2nd and 3rd axle. It is remotely controlled with a small linear actuator driven by a PF M motor between 3rd and 4th axle. Total gearing in 1st gear is 23.2:1 and in 2nd gear 8.3:1. 1st gear is pretty sluggish but does the job well and the 2nd gear is good only for rather flat terrain with minor bumps. Unfortunately, I ran out of place for hiding the motors inside the chassis so not to good looking from above but the body covers them well from the side. I had to rebuilt and modify the gearbox a couple of times, bracing each pair of gears as close to them as possible. Previous versions of gearbox resulted in some ABS abuse as you can see on photos below . Front two axles are steered by an L motor which also turns the steering wheel in the cabin. Steering mechanism is a modified 2 axle steering system from Madoca’s Tatra T813 which is some studs wider than my version. Below the cabin there is a working mini fake V12 engine with fan (original design by @jorgeopesi). The cabin has two seats, some gauges around the steering wheel, and fake shift stick. As you can see, I had to make front axle suspension pretty stiff due to heavy front of the truck. There are three pairs of hard spring shock absorbers on 1st axle, two on 2nd and 4th axle, and one pair on 3rd. When there were only two pairs of shocks on front axle, the truck was sagging pretty bad. And now (IMO the highlight of this MOC) to stickers. The truck is full of them, as is the real truck. I searched the web for some that I found cool and funny. Stickers were printed on plain white sticker sheet and some on a transparent sticker sheet for laser printers. The latter took some colours very well and some not – especially red colour pealed off rather quick, which made the rad claw marks look old and worn out which turned out even better. I find it quite hard to tear it apart as I am very pleased with how it turned out. In addition, teardown is being postponed continuously because the transparent sticker sheet leaves some glue spots on bricks and I haven’t found the right mood to clean them. I hope you don't mind, if I point them out... A funny thing with those septic tank cleaners - on Facebook,a guy from Republic South Africa comes out and says he sees trucks of this company all the time as they have HQ in town next to him - small world isn't it? I hope they don't mind some extra commercial . To end, here are some more photos from the beast’s natural habitat and a video of course. In order for you not to fall asleep, I sped up some of the footage. I also apologise for some part of the video being a bit on the lower side of quality - it comes so that my cellphone is practically all my shooting gear. Thank you for your time reading this and I hope you like it. I am looking forward to your thoughts and comments. Fire away. Higher resolution photos can be found in my BrickSafe folder. Best regards, Miha P.S.: In case someone wonders, how I did on the race – see photo of competition below. Mine is that small yellow fella in the middle. As you can imagine, I was no match for those small and fast woodpeckers
  6. Hello everyone, I'd like to share a MOC from my collection: MAZ 537 Military Tractor 8x8 Done in the scale 1:20. Dimensions: 43cm length x 16cm wide x 15cm height. Weight - 1100g. Functions: - PF XL for all-wheel drive; - PF servo for 2 front axle steering; - The drive chain is done through knob wheels; - Openable doors and roof hatch to access buwizz; - No front axle (2) suspension; - Pendular rear axle (2) suspension limited by the frame; - Imitation of trailer grabbing mechanism. The drive chain is geared down 1:3, no differentials. As a result it drives confidently. The steering is done through 2 big steering racks, one connected at 4 pins from the center of the wheel, another one at 5. Fixed by 1x2 liftarms that slightly imitate ackermanns steering by moving without moving the gear rack. I wasn't sure it will be okay, since the main weight is concentrated in the front, but it was fine. Gave it a hard obstacle course and offroad performance is more than bearable for its clearance. Driving this thing really forces you to seek paths and I don't think it is a minus. More photos here: https://bricksafe.com/pages/gate/gate-lego-technic/maz-537-8x8 Please, let me know what you think
  7. Hello everyone, My new creation is a big Tatra. It is my first 8x8. All problems of size, weight, friction and powertrain were the most challenging for me. Total weight: 2790g 2 hard coupled XL motors for 8 wheel drive without differentials. They are connected to each output of V2 receiver #2, powered by 8878 battery of left side. (Motors of the rest are connected to V2 #1, powered by 8878 of right side) 1st and 2nd axle are steered in different angles by 2 L motors. M motor for 2 speed heavy duty gearbox. 9:1 (high) 25:1 (low) Working steering wheel and V12 engine. Openable hood and doors. External roll cage and LED lights are easily removable. This is my suspension setup. The central axle is free from the friction by the force of suspension movement. Each 6.5L springs limit the angle of swinging half-axles. In these limited angles, bevel gears smoothly engage. Since the building process was complicated, I haven't made instructions yet. Hopefully it will be available in a few weeks. I drove it in high gear in most part of the video. Despite heavy weight, not a single gear was damaged. In low gear, it is surprisingly powerful. Video: Building instructions and more pictures: https://plus.google.com/u/0/photos/117021167471864977943/albums I hope you will like it!
  8. Hello everyone! Since TLG released 76023, I had been waiting for affordable Technic set which includes so-called Tumbler Tires. So I jumped at 42050 Drag Racer. I also bought some extra tires separately, then revived old project which had failed three years ago. Avtoros Shaman 8x8 Building instructions: Rebrickable Weight: 2550g - 4x L motor for 8 wheel drive - 2x Servo motor for 8 wheel steering - M motor for switching steering mode (AWS and crab) - M motor for winch - 3x LED for front and rear lights - 2x SBrick powered by 2x 8878 rechargeable battery box - Independent suspension for all wheels - Working steering wheel - Openable hood, doors and roof hatch Back in 2013 As you may know, real Shaman is which can go through almost any kind of terrain. It has three steering modes and can scale 45-degree incline. On top of that it is amphibious. Seeing pictures and videos, I instantly fell in love with it.When I started the project, I was too ambitious to realize all features above. Sadly I could not build even steering mechanism while keeping all wheel drive and independent suspension. So I changed the project to building another 8x8 vehicle. It ended up as my Tatra 813 Trial Truck, but that is another story. Focus on characteristic features Two months ago, I suddenly came up with an idea that enables both normal AWS and crab steering. In the case of four-wheeler, you can do it by switching rotation of second Servo motor for rear axle. But in eight-wheeler like Shaman, you should change turning radius of second and third axle. In normal mode, the steering angle of inner two axles is smaller than outer axles. But in crab mode, all axles should be steered at the same angle. This is the basis of steering idea. I used the way of fixing/moving pivot of steering linkage. A: There are two 7L steering racks connected to 7L beams. Front rack is connected in the middle of beam, rear is one stud backwards. Both ends of beams are connected to steering arms of each axle. B: In normal mode, rear rack is fixed by 12T bevel gear. So the fixed pivot of 7L beam is its 5th pin hole. Which makes front end of beam moves twice as rear end does. That means the steering angle of 1st axle is twice as 2nd axle. C: In switching crab mode, 12T bevel gear moves one stud forward and fix front rack. Fixed pivot is 4th pin hole of beam. Which makes both ends of beams move equally. That means the steering angle of 1st axle is the same as 2nd axle. And there is one more twist. D: I put main steering rack (moved by pinion gear) on one stud forward of 7L beam's front-end (which means 9L beam’s front-end). Seeing from the pivot point, this rack is connected to farther than the point of front steering arms connected. So front steering arms always move slightly shorter than main rack does. When Servo fully turns 90 degrees, pinion gear moves the rack in one stud sideways. Steering arms move less than one stud. This was necessary for keeping CV joint (connected to steering hub) rotate smoothly even when fully steered. Challenge and compromise First of all, this MOC is NOT amphibious. It is too heavy to float. And because of driving motors of low position, chassis is not waterproof at all. So it is not recommended driving it through even shallow water pool. My aim was to achieve decent crawling capability. But I had to lower the bar because there was no room left for portal/planetary hub reduction. Without them, heavy load from 81mm tires directly goes to 12T half bevel gears. First attempt was using two XL motors geared 25:9. I put each motor for left/right side of axle. The result was unsatisfied. Even when climbing over small obstacles, bevel gears often slipped and got damaged. So I replaced them with four L motors geared 3:1. Each one drives a pair of half axles. Thanks to their good speed and smaller torque, new drivetrain proved to be more reliable. Although bevel gears were still slipping a bit, I accepted overall performance. The picture above shows two L motors for driving right side of axles. The power functions switch for changing rotation of rear Servo motor is synchronized with moving steering pivot mechanism. In crab mode, rear 4 wheels steer opposite the same direction as front wheels. As always I used few of non-Technic parts. Big roof tile was used for saving weight, curve slope parts were better choice for filling the gap. LBG axles sticking out the roof are visible indicator for steering mode. They are mechanically connected to switching mechanism. In the video you can see how they work. Instructions available at Rebrickable. Building it in red is possible by using red parts instead of white. I hope you will enjoy building!
  9. Hi all! I present my newest project, which is among my biggest ones ever. I build the monstrous Maz 535, inspired mainly by real life Maz (537, because there are no working 535 any more, if I know well), and a bit of Spintires. I know about this heavy truck before spintires, too, but when the tech demo released, I could finally "drive" it, simulating a bit the behavior of this truck. It's an awesome and indestructible machine, a real russian cold war truck. So it shouldn't be missing from my mocs. I build in 1:15 scale, which means the 108 mm tyres. Of course, in this size I'll use again the crawler tyres, RC4WD rock crusher XT's, and maybe later I'll buy a more authentic looking military tyres. I'll make the tractor truck, so there will be no cargo platform in the back. The real life vehicle: ---> this will be my version Thanks to spintires, we have some good looking high quality render, so I can make the details properly: http://www.simulasyonturk.com/wp-content/uploads/2012/10/spin-tires-maz535finihmodel1.jpg http://2.bp.blogspot.com/-1Lya0MYqf-I/UJXplkmcyuI/AAAAAAAAALQ/aKsF8vN25O8/s1600/maz535_04.jpg http://4.bp.blogspot.com/-oRD07JncgzY/UJXpgYwP83I/AAAAAAAAALE/A1tpVtJo1Gk/s1600/maz535_03.jpg https://i.ytimg.com/vi/sRDnX2OQ37I/maxresdefault.jpg My goals: - 1:15 scale --> 108 mm custom wheels - 8x8/4 (first two axles steered) - Radio controlled with RC buggy system, 1 RC unit, 2 RC motors - very robust drivetrain and steering - proportional looking, with model body and details, as close to the original as possible - 24 studs width at the wheels and body - full authentic (independent in front and semi-independent in rear) suspension with minimum 2-3 studs of suspension travel - no portal or planetary hub - 2 speed gearbox controlled by the RC unit's servo - working towing cable, with heavy winch and hook (metal) - working headlights - dark green color There will be pictures about the process soon, first I make the front axles and the main placing of components, steering. I collected a pretty large amount of dark green bircks, tiles, etc., so the color shouldn't be a problem. Fortunately, there are curved dark green bricks, to make the curved edges in the top and front. The gearbox would be a sliding type, and it's movement will be done by the servo of RC unit. To help in this process, and fix the slifing axle in the second gear's position there will be magnets somewhere. By default, the gearbox will be in first gear, when the servo is in 0 position, so it will be reliable under torque. The shifting to second gear this way will be an additional extra, if you want to do. It's a heavy truck (will be about 3 kg), so even with robust drivetrain I think it won't be capable of doing trial/heavy terrain, but if a medium can be done, that's far enough for me. If a 30° slope and a terrain with 3-4 studs high obstacles is no problem, then I reached my goal with it's off-road capabilities. Comments and questions, ideas, etc. are appreciated, as always.
  10. 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:

    [9v MOC] CMF vig: March Harriet

    Hello everyone! What kind of ideas pop into your head when you hear of a "cmf 8x8 vignette contest"? Mind you, I eventually thought of Micromotor, 9V, Fiber Optics and a matching figure capable of delivering the goods (hint: it did). Here's what came out of that idea... Just a dance club, folks! Nothing to see here, carry on... It is fairly tall for a vig, but it certainly works give the space restrictions. The dim lights were a pain to film in my setting, although I tried my best. The show must go on, no excuses allowed! And no regrets for that matter. Welcome the Catwoman from the Batman Movie franchise! Double the fun!! Some technical shots. The old 9V system is invaluable for how smoothly it integrates into Lego System. Fitting the fiber optics element into 8x8 was one hell of a task. At times I felt like a car thief on a job... The floor, oh, the floor! Don't even ask. Some bits and pieces. The pole absolutely had to be chrome - a choice afterwards regretted... I dare you to find a sound, functional and purist solution of proper length if you don't believe me. A rubber wheel was the only option of attaching the piece as far as my knowledge of pieces goes. ...And the heat goes on... Now that's a club I wouldn't at all mind visiting... Hope you had a great time here, be sure to visit soon! And something tells me you might just do that... Thanks for your attention! Let me know if you had as much fun as I did! x)

    Tatra 813 Trial Truck

    This is my biggest technic creation (so far). It's trying to be a Tatra 813 8x8 truck, with a shorter cab. 2 XL motors provide traction for all wheels and an M motor steers the 2 front axles. For now it will remain like this, as it will enter the Rolug Winter Trial Truck contest and needs to be as light as possible, but after the contest I'd like to continue working on it. I think it would be a good off-road tow truck/mobile crane or a drill rig carrier 20180123_190938 by tamas lapsanszki, on Flickr 20180103_090528 by tamas lapsanszki, on Flickr 20180101_003044 by tamas lapsanszki, on Flickr 20180101_002001 by tamas lapsanszki, on Flickr
  13. Hi all, A little presentation of my LEGO Forwarder named XXL for obvious reasons :) It has been a project in my spare time for some years now and still not finished (probably never will be...) Most basic facts: Weight: 6,7 kilograms Dimensions: 95xx36x50 studs Drive: 8 XL motors + hub reduction Steering: Forced by controlling front left with rear right and the other way around (because of the weight in combination with the huge friction from the wheels) Wheels: From 8466 (4x4 Offroader) Some vids from Youtube: Feel free to comment or ask questions, I´ll try to answer them :)
  14. Hello, i tried to realize a scale model of a MAN TGS 41.480 8x8 for heavy duty applications. Decals and some Little improvements are still missing, but they will follow.
  15. 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

    [WIP] MAN TGS 44.480 8X8

    Hello, this is a WIP of my latest moc: a MAN TGS 8X8 leafspring suspended fully RC with autovalve compressor pump! Plus many other features and functions. It also features many attachments, like a Fassi F1950 XP crane fully RC using new pneumatic V2 system! It also has a dumping load bed, a front snow plow (this will be shown later on when completed! The idea is to use the cabin and chassis as a starting base to develop more mocs like the XXL version of the same truck, 3 axle, 4 axle, 5 axle. Functions: - 8X8 driver train driven by 1 L motor - Realistic steering system with levers (plus different angles between 1 and 2 axle) steered by an M motor - Pneumatic compressor with autovalve powered by an L motor - 2 IR receivers that controls the drive, steer, 1 pneumatic switches (in this case used for tipping the bed) and 1 more motor for extra function (in this case used to rotate the crane) More pics here: http://bricksafe.com/pages/TheItalianBrick/fassi-f1950-xp http://bricksafe.com/pages/TheItalianBrick/man-tgs-44.480-8x8 I'll progress I'll take more and better pics. Enjoy what I have so far! And this is the crane, it's also a WIP but so far I'm happy with the result!
  17. Hi everyone! I am glad to present my new trial truck based on @Lucio Switch and @efferman ideas. All photos are clickable, you can see full Flickr gallery Main goals were: Enormous size of the model Durability High speed (relative to most lego trial trucks) Double wheels on rear axles Features: 8x8 drive (no differentials) with 4 buggy-motors (12 wheels total) 2 servos for steering 2 L-motors for winch 2 SBricks 2 LiPo's In-wheel planetary reductors (4:1 gearing) Anti-roll bars Durable 3-stud thick chassis Total 22:1 gearing with fast buggy-motor output Weight: 3,5 kg And here are some WIP photos: Axles with 13:1 gearing Rear chassis part with motors installed Chassis assembled Almost completed truck, with bottom view First steps Video from Moscow 2016 TT meeting As a final note, I can summarize that such heavy and hulking truck looks good only as a show-stopper, but there is nothing to do with it on trial competitions Thank you for attention, hope you liked this little fellow
  18. It's been a long time since I posted an MOC... I never finished this model, and needed the parts for something else. So I made an LDD file of what I did build, which I recently rediscovered. It is based off the Arocs dumping bed, but now has 3 suspended axles, all driven. The fenders were extended, and there is an automatic tailgate lock. There were a few parts used in place of others, more details if you follow the link. If anyone wants to use this on their own model, go ahead. Sorry, there are no pics, and it has already been dismantled. Just wanted to make this available for anyone who wanted it or was interested in it.
  19. Hello Community Today i started a BIG Project. I´ll try to build it as near as possible to the original. Thanks to IVECO they show the details of this truck on their Webpage. (I found it only in german) Functions planned: AWD Pendular Suspension It has leafsprings in real life. I know leafsprings are possible. But not in my scale i believe... But i´ll try When i can´t reaplicate them i will use springs instead 3. Because my last big project failed because of the weight (and broken universal Joints ) i will build in only 1 BB, 2XL, 1 Servo Tires: I think these tires look great and fit the tireprofile realy well. Wheelhubs: I made some heavyduty Wheelhubs for my truck. LXF Updates coming soon. Improvements, Suggestions and Critic are welcome!
  20. Hi Guys, I would like to share my 8x8 medium dump truck with you. The target was to create 8x8 dump truck with 4 differencials in compact size with good driving abilities. It drives quite well, but due to large amount of gears, even XL motor have some trubles (wont stop, but you can hear little bit) while steering/climbing, but I'm happy with result, even view could be better. Some info: Propulsion: 8x8 by PF XL Steering: 8x4 by PF Servo (different angle for second axle) 1 Differencial for each axle Dumping by 1 M motor. No suspension, but thanks to flexible body, it can go well over obstacle. Opanable doors I'm sorry for really bad quality pictures, will upload short video soon. What do you think?
  21. Good day! After watching truck trial videos on YouTube I decided to make my own . The digital version was finished one month ago , but I had to buy 8 55976 tires to build it IRL. It was completely designed in LDD , I was afraid to have some weak points , but it resulted being one of my best designs ever done . There have been very small changes - different colors of some parts & improvements on the rear cabin support & front suspension supports. download LDD file Bricksafe The truck can be powered with any studded battery box. The drive is done by worm gears and 8t gears. Thanks to that , even using 1x m-motor for drive it is quite powerful. The steering is done by another m-motor geared down 1:2. The front axles have different steering angle. The weak point is the chain drive which sometimes skips, acting like a clutch gear. The IR receiver is completely hidden inside. The rear suspension is pendular, and both rear axles are linked and supported by 9l links ( idea from ZBLJ's trial truck) The front axles are linked to the chassis and between them by 6l links , and linked to the body & between them by 9l links. I haven't came up with a good enough interior, but there's enough space for it. LDD file Thanks for reading, I will make a video soon
  22. Just an 8x8 Vignette, for the Flickr Summer Joust contest. I made a simple base with a small battle scene on it. Not really a story, but it's a viking woman ambushing a soldier of the Empire of Evilness. Hope you like it, C&C welcome!

    WIP Tatra T-815 8x8

    Hi guys, I waned to show my latest creation a 8x8 tatra truck. It's still a wip (for a very long time now) but I bought 2 new sets with some piecies I needed. Right now I'm going to focus on the cab to make it better looking. Will post updates when I've had some progress Here are the pictures ]
  24. As I am a big fan of Quattro & Co., I allways wanted to upgrade my models with AWD. For christmas my wife gave me the 8258 Crane Truck and - as most of you - I think that this was a milestone in the Lego Technic Flagship era. So after finishing it I immediatly started to think about the possibilities of upgrading this excellent set with 8x8 and other improvements. Here you can see now my progress so far: Added double wheels in the back added second driven axle in the back (as developed by BS-user arachnid) added most of the improvements of Designer-Han added opening doors added (first?) center differential added the first driven front axle See here the first impressions of my changes. ..... ...... . In the moment I think about adding a second center diff between the two front axles, but I am not quite sure, if that is neccessary for the playablity (torsion in the drive train and thus rubbing tires). I will test that. Updates will be posted here soon.
  25. Here's my Phase 1 build for the storehouse category in Age of Mitgardia. I limited myself to an 8x8 base size for this build, and was mainly trying to make a realistic looking cellar entrance. Fruit cellars are commonly used in Mitgardia to store food, and other goods. Rats can become problematic, but it looks like this one's food stealing days are over: See more pictures here: link Comments and suggestions welcome
