Hi guys! As some of you may know, I'm a huge off-road fan. I never really saw the potential in on-road, and sometimes found it boring. But then, I watched a few drifting videos and instantly saw the potential to make a LEGO drifter. I got in touch with my friend @N1K0L4, which is an on-road fan and has experience in the field, and sent me a couple of chassis designs. I obviously chose the most overpowered one You can check out N1K0L4's chassis here, and the full rebrickable post here. Now, let's go with the details: Features RWD with 2 BuWizz Motors Steering with a C+ L motor Realistic looking bodywork resembling Ken Block's Hoonitruck All fueled-in with a BuWizz 3.0 unit For me, one of the most important functions is the drivetrain. It's built in a very clever way with the 2 BuWizz motors leaving just enough space for housing the BuWizz 3.0 unit. It's RWD, which isn't true to the real-life counterpart, but N1K0L4 is working on a new version with AWD and it's looking very promising! updates about the AWD version will be made in this topic. To finish it off, the steering was added, using a rack and pinion setup to have as little slack as possible as that's a key factor in mini-racers. It's steered with a C+ L motor as said earlier, with this being my first time using C+ electronics. I have mixed feelings about it, but more on that later. The bodywork was an interesting one. I wanted it to be as accurate as possible to the real deal, but I had to use white mudguards as LEGO for some reason doesn't produce them in black. Still, they didn't spoil too much the body for it to be recognizable, so I'm happy with it. Still, it was somewhat flimsy and would tear to pieces if I hit a jump wrong. Still, N1K0L4 has also addressed this while still making it more accurate. I guess union makes strength For the video, I wanted to use a different setting in comparison to my other videos, as it's a very different model to the previous ones. I chose to go to a skate park, as it had some smooth concrete sections for drifting, and ramps to do some jumps, which is exactly what this model was built for. The model handled excellently in spite it's RWD, although I'm not used to models this fast, so I hit jumps wrong dozens of times. There are some included in the video, but many weren't included, but I'm considering making a bloopers video. How would you guys feel about that? However, the parts didn't like the skate park, as concrete is very abrasive to abs plastic. The splitter was melted and torn to pieces, and the tires lost most of their thread in the process, up to the point where I had to use to sets of them to record the video. I guess I'm a bit of an aggressive driver, but you should be aware of that if you build this model. About the C+ electronics, I'm not fully sold out. They do have some pros, like the more convenient shape of the motors or the faster response, but they show some disadvantages when taken into closer inspection. The steering trim was a pain to get right, and even when that was the case, it still veered ever so slightly to one side. I think it has to do with the fact that the 0 position is digital and not physical. Still, I'm considering using them in future build mostly because of the easier integration, but will probably stick to PF servos for faster models as they return to center more accurately. Feel free to post a comment about what your thoughts are about it, and see you in the next one! -
Hi Eurobrickers! I'm back with the new MOC - this time it's a new Mammoet SK 6000 crane! Current configutation is Mammoet SK6000 + Mammoet SK350 Fixed jib (which is compatible in real life) Original ring crane was just recently released by Mammoet in Netherlads! This is fan work. For built used only open source resources from WEB! Ok, also this MOC was built with unofficial consulting with Mammoet engineers, because it was a lack of the info in WEB, so I have to ask some thiings to match the real masterpiece crane. UPD: I was invited to the real crane's world presentation on last (or prevois) Friday to the Netherlads with my Crane MOC to show it at the mass media day near the real SK6000! Unfortunately I was on vacation that time and lost this once in a lifetime chance.. How it works: Centered counterweight is fixed and non movable, around it there are two train racks (imne are almost 180 degrees), so the crane is rotating arong the ballast. Real SK6000 does not have it, but from SK350 I took the jib which was surprisely fix and not luffing - it has no adjustments. Machine is able to lift 6000 tons and lift 2000 tons at the lenght of the footbal field from the basis !! The main feature of this crane is that it does not use winch to operate the boom - it uses special mechanism with chain, so I implemented this also :) Please enjoy the video first: Built with genuine Lego technic parts + 3rd party strings + 2 BuWizzBrick 's. I refused using trixbrix curved rails because found a solution with genuine lego parts. The model has 7500 parts which makes it the biggest MOC in my career! It has 8 L motors for smooth operating, powered by two buwizzes. Crane weights 8,3 Kg excluding power sources (battery boxes) and counterweights!! And the height is about 2.3-2.4 meters. More images are available: https://bricksafe.com/pages/Aleh/mammoetsk6000 Building instructions already available. Built took 1760 steps, which required a lot of effort to prepare it. https://rebrickable.com/mocs/MOC-195537/OleJka/mammoet-sk6000/#details

This is a model I've been working on for a few months for the BuWizz gathering and now it's finally time to showcase it. The rules required a 1:10 scale model built after a real vehicle with a working gearbox, steering wheel and fake engine powered by a maximum of 2 BuWizz motors. I also managed to squeeze additional functions and features as following: 2x BuWizz drive motors 1x BuWizz 3.0 for control Working steering wheel actuated by a PU L motor 2 Speed motorized gearbox controlled by a PU m motor All Wheel Drive using planetary hubs Independent double wishbone suspension on all wheels with around 2 cm travel Working fake V12 coupled directly to the drive motors Detailed interiror with tilting rear seats to access the BuWizz Detailed exterior with opning doors, bonnet and tailgate Built out of around 2850 pieces 47 x 21 x 18 cm Weighs around 3 kg As usual with my representations of the real vehicles, I first started with sourcing, editing and importing a 3D reference into LDD. Here's how the digital model looks compared to the LEGO version: And here's the LEGO version without the reference: I hid the doors, bonnet and the tailgate in order to show the detailed interior: The driveline is very compact and efficient. Two BuWizz drive motors are placed right behind the rear seats and power the 2 speed gearbox and an (oversized) V12 engine directly. As with the real vehcile, suspension system is independent at all 4 corners. Steering system is actuated by the steering rack directly and geared up. Gearbox is activated by a PU M motor via a linear clutch and a wave selector: So that was the theory... After a few small fixes and corrections, this is how the finished model looks like in real life (oops, I lost my license plate): Rear view showing the spare tyre, detailed lights, guardrails and exhausts: Doors, bonnet and the tailgate can open up to reveal the massive V12 engine and front shock absorbers: Interior features an adjustable and working steering wheel, 4 fully detailed seats, console and a transmission tunnel. Rear seats can be tilted individually to access the BuWizz 3.0 for charging; Here's a view of the back with the opened tailgate. Thanks to the central motor placement, there's a lot of free space: One of the design goals was to protect all the gears and drive axles from dirt and to keep the bottom as flat as possible. I think I did very well, it's smooter than the real vehicle in that regard: And finally here's a video where among other details you can see how well it performed at the competiton: If you want to have an even more detailed look, you can download the LDD file here: https://bricksafe.com/files/Zblj/lamborgini-lm002/Lamborghini LM002.lxf To summarize I'm really proud of this model. It looks, performs and just feels good and hits all the right spots. One thing's for sure, I'm keeping this one assembled, as I trully believe it's one of the best models I ever designed. -
Hi, I would like to present you my first MOC prepared especially for official LugPOL Truck Trial Championship. MOC is based on very famous, polish truck with good off-road capabilities - Star 266. I choose polish truck to introduce some local technology to the competition dominated by soviet machines. Instructions are free of charge, so if you have parts and some time, you can enjoy off-roading with this model pretty easy. LINK Here are my priorities when designing this truck: to fulfill LugPOL Truck Trial Championship rules and to provide truck which will be accepted by judges to prepare truck with good off-road capabilities to build it to make it recognizable Couple of LTTC rules: scale: 1:12 to 1:14 number and type of axles true to the real machine type of suspension true to the real machine must be RC and all-wheel drive the truck's cabin true to real machine, with roof, seats, steering wheel, floor and with openable doors All above rules were fulfilled, below there are couple of more details: scale: 1:12 drive: 2x PF XLs coupled, if necessary, each wheel can harness power of two XL motors steering: PF L motor weight: ~1990g dimensions: W x L x H: 25 x 64,5 x 32,5 studs (width without wheels and tires) Star is powered by Buwizz 2.0, but since it uses only PF motors in very simple configuration, it can be powered by anything you have Truck was designed to work with 96mm Tamiya CC01 tires, and those tires you will see on the video. But in the instruction I used the closest in case of size official Lego tires. You can of course put bigger tires, like Lego tractor tires: 107mm, but some rubbing during extreme off-roading is possible. Couple words on the truck itself: Star 266 took part in two competitions in 2023, so it is well tested, any minor issues were eliminated and I'm convinced, that it can be used in hard terrain without any worries. It is rather simple construction, to reduce the weight. Details are there mostly to be able to fulfill competitions requirements. The truck is the mix of many ideas I had during designing and I wanted to test during proper, official competitions. Some of them proved to be hard terrain effective, some of them, not. So this is for sure not the ideal trial truck. But it is not afraid of outdoor obstacles, mud, dirt, stones etc. Pros of Star 266: high ground clearance (7 studs with 96mm tires) high approach, break over and departure angles highly response suspension with long travel to fast and precise surface adaptation each axle is connected directly to coupled 2 PF XL motors, which allows to stable, equal speed of all wheels and provides (when needed) all available power for the wheel which needs it the most steering is done with PF L motor for speed and strength, possible steering angles are > 45 degrees per site Cons of Star 266: turntables used in each wheel introduce friction, quite a lot of it, I highly recommend to try to reduced it as much as possible (I advise to use a bit of sanding or lubrication, or both) due to lack of any shock absorption, stability is only on decent level truck's cabin shape and location is not the best in case easy passing the gates during competition, but this is my personal opinion Internals of the MOC, so drivetrain and steering with motor on front axle More photos: https://bricksafe.com/pages/keymaker/trial-truck-star-266 -
[TC27] Lowrider
Zerobricks posted a topic in LEGO Technic, Mindstorms, Model Team and Scale Modeling
Here's my entry for the TC27 - the physical model is also completed and tested, but I'm stil waiting for the 2x C frames (3167) to arrive (for testing purpose I just 3D printed my own pieces ). Anyway, I wanted to build something unique and different this time around. I've been thinking of building a motorized lowrider for a while now and this challenge was the perfect excuse to realize it. With this model I wanted to realize the following functions: Motorized suspension Steering mechanism connected to the steering wheel Working fake engine driven by rear wheels Openable (suicide) doors, hood and boot Proper, clean and spacious interior Along with those functions I also managed to squeeze one more additional function, which makes the car a convertable. Here's the end (digital) result: So as you can see, it actually uses the correct tires and rims which I think is a good start! Here's how it looks like all opened up - notice the inline 4 fake engine: Here's a look from the rear, showcasing the large rear typical of lowriders, which is also used to house the two BuWizz 2.0 bricks. I took great care to give the model some fins, proper brick-built lights, bumper, exhausts, etc... Looking at the underside you can see that the L motors are also structural, both axles are designed around them: And here's how the Driveline, Steering and Suspension system are integrated into the model: As mentioned before this is also a convertible which means that the roof can be unfolded and raised: Now for a little of backstory. Originally I tried using PU L motors to make this model a bit more intelligent and capable of holding the wheel suspension positions automacally. Unfortunately PU motors have a very sensitive current protection and were simply not capable of holding the weight of the car even though I'm using shock absorbers to help carry weight. Worth mentioning is also that suspension arms are shorter in the rear to compensate for extra weight. I could have added extra gearing, but that would make the model even bigger and suspension slower. So I took some L motors I had laying around from the Go-Kart project and used them in place of PU ones. Thanks to their shorter size I even gained some additional space and reduced complexity. During testing I decided to double up the BuWizz bricks. I did that for two reasons, first to increase the weight in the back for higher front bounces and secondly to supply the needed power to actuate 4L motor at maximum speed at the same time (each motor draws some 2 Amps when stalled in Ludicrous mode). I hope that's enough details and media for now, I will post photos of the real deal once I get the missing parts and I will of course record a proper video. -
I usually don't really post much of my work here, but sometimes I'm too proud of a certain model... Like this one. Designed in colaboration with a Slovenian GM racing team, I present you my interpretation of a 1:10 scale Ford Fiesta RS WRC Rally car. The realized functions and features are as following: 4x BuWizz motors for all wheel drive - one for weahc wheel, powered by the outer output 1x PU L motor for steering Independent high travel suspension on all wheels Working steering wheel Powered and Controlled by 2x BuWizz 3.0 Inline 4 cylinder engine driven by the front motors Opening doors, bonnet and rear hatch - the rear hatch usues shock absorbers in a bi - stable mechanis to keep it closed or opened Custom 3D printed wheels for 62.4 mm tires Detailed interior with a rollcage and bucket seats Built out of cca 1650 pieces As usual in such projects, I use a 3D reference model which is imported in LDD in order to create the most accurate representation: Here's the final virtual model - ready to be realized from physical bricks: You can see one BuWizz 3.0 under the bunnet in the front, powering the front wheels and the blue cylinders (half pins) of the inline 4 engine: Rollcage is designed with a mix of liftarms and links and it is actually structural. You can also see the second BuWizz in the rear: Anotehr view of the opened up model: Bottom view, showing layout of the motors - Front motors are just behind the grille, it was a really tight fit: Once the digital model was done, it was time to build it from real parts, 3D print the wheels and apply custom stickers. Here's the final result: I'm really happy about the shaping, there are almost no staright lines, almost all the panels are at an angle, for example the curved 3x11 panel above the rear fenders: As mentioned before, the steering wheel is connected to the steering motor (the blue clutch gear moves it). The steering wheel can also be adjusted using click hinges. Also notice the red fire extinguisher on the passenger side: Soft grey shock absorbers keep the rear hatch closed/opened: Inline 4 clyinder engine is powered by the front motors from the fast outputs via blue rubber belts. They can slip when needed while cornering: And finally here's a video where you can see it in action along with more details: To summarize, thanks to the 3D reference the body is very accurate with almost no straight lines and I'm getting really good at sculpting complex shapes. Great care was also put into keeping the car as light as possible so it reaches over 15 km/h, yet has enough torque to drive/jump over bumps, hills, etc... Thanks to the Audi's hubs, the suspension has a lot of travel and a single (black) hard shock absorber per wheel is enough to support it and absorb the hard landings. To conclude, I'm really proud of this model, it's a really nice balance of aesthetics, performance, robustness and fun!

It's been a while since I posted a personal MOC here, so it's about time to fix that! After the competition we had in Cluj in Romania last year, I decided to make an AWD version for my next competition car and to include the lessons I learned from the Sterrato, Mustang GTEX and others. For this version I used a single BuWizz motor to drive the model, which is realistically placed behind the rear axle. It drives a 28 tooth reinforced differential via a 12 tooth bevel gear from the fast, inner motor axle: Rear differential also drives and axle that in turn drives the normal differential in the front, providing front wheels with power. An L motor steers the front wheel to the maximum angle CV joints can provide, 25°. Exterior is loosely based on the 911 Dakar edition, though some details had to be omitted/recolored due to lack of small panels in white color: I also had to simplify the rear section a bit in order to fit the motor, but it still features details such as LED bar, lights, exhaust and a skid plate: Dimensions: 29 x 12,5 x 8,5 cm Part count: 595 pcs (actually very low for a motorized model at this scale) Weight: 650 grams Thanks to the redesigned front axle which uses the normal diff, I also managed to increase ground clearance to almost a stud, allowing the model to be driven over rough terrain as you can see here: As usual, the LDD file of the model can be downloaded here (remember to update LDD first): https://bricksafe.com/files/Zblj/116-porsche-911-dakar/1 to 16 Dakar 911.lxf While not the fastest or most powerful 1:16 model I've ever built, it sure is one of the, toughest, reliable, robust and simply fun ones to drive so far. To conclude, I'm also really happy with the looks, thankfully Porsches are quite easy to build with Technic and I think it's a good representation. Even kids recognized it as a Porsche while recording the video, which I think is a good sign.

One BuWizz, it's good. But two, it's better, because you can make MOCs having 8 functions! I have already done a full RC compact excavator, but with LEGO IR receivers. I wanted do make another excavator without the gearbox allowing to choose between the rotation of the arm and the pneumatic pump. Furthermore, the M motors were just enough powerful to move the arm. On this new excavator, it's different. I tried to make the mecanic as compact as possible. And the arm is controlled with more powerful motors: 1 L and 1 XL. So now you can... dig on gravel with a GoPro attached on the arm, and the motors bear that easily! There is a good speed and so much power to do anything you want! For the design, I tried to cover the maximum and I kept a color scheme close to the one of my previous excavator. To switch on the BuWizz of the turret, you need to open the part behind the cab. The hood is also openable, but there is nothing interesting to see. ^^ So the functions are: -> Controlled by the bottom BuWizz: Left track (M motor) Right track (M motor) Blade (M motor) LEDs (of the cab and the arm) -> Controlled by the BuWizz of the turret: Turn table (L motor) 1st part of the arm (XL motor) 2nd part of the arm (L motor) Bucket (M motor) You have certainly noticed that there are shock absorbers. It's for the tension of the tracks. The LEDs: And the video! The BuWizz are in Fast mode and I used the app BrickController, done by @imurvai. It's perfect for this MOC! -
Here are my 1960s Corvettes. 1961 C1, 1963 C2 and 1969 C3. They are all based on this simple buwizz powered chassis. It has a servo for steering and a single L-Motor for drive. Front suspension is like 42039 and the rear is similar to 8081. The C2 and C3 have a shorter wheelbase than the C1 so there are two slightly different version of the chassis. 1961 Corvette C1 1963 Corvette C2 1969 Corvette C3 -
Hi everyone, Finally, I have finished a project which I was building since last September. It is the scale model of the Intrac 2011 snow blower which is/was often used in the swiss alps by the army and other communal parties. It was the aim to create another working snow blower after the success of the snow blower from last winter. The blower is powered by three buggy-motors which are all controlled by a separate Sbrick. Each track is driven by two PF XL motors. The snow blower shoot direction is controlled by two 9-volt micro motors and the height of the snow blower by one PF L motor. As power source I used two Buwizz as battery or a custom lipo battery. After a certain time in the cold I had the replace the Buwizz with the custom lipo battery. Cheers FT -
Here's a MOC on which I'm working since the end of the previous summer! After I have done the video of my DS3, I had the idea to do a new chassis with 4 wheel drive. I thought it would not be possible, but the first prototype was better than my DS3! Actually the MOC is not finished. The stickers are missing, and I'm continuing to develop the chassis (I'm adding a 4th L motor) Actually there are 1 L for the front, and 2 L for the rear. The great advantage of the 4WD is that it can take a great angle while turning, but it's always controllable. But, that can have an inconvenient: the understeering. For that, I did the same thing on the real RC drift cars: I added a free wheel. So when I do not accelerate, the front wheels are not braked and the car does not understeer. You can see this video on this video, done for BuWizz with Charbel. But this is one. It's the same thing, but there is only my car. The final gymkhana will be for the next summer, because that requires a lot of time, and with the school, I have not enough time at another moment of the year.

Good Day. This is a small desert-rally styled offroader that was made in roughly 8-9 hours during New Year's holidays. Weight of 637g. Powered by BuWizz v1. Features: -4x4 drive with slowest output of buggy motor -Return-to-center steering (m-motor) -Independent suspension on all wheels -Over 2 studs of clearance under the car -Openable doors, bonnet and trunk. -Detailed engine bay & interior -Stickers all over the car, including rear-view mirrors & rear lights -Minor detailing on the outside (lightbar, antenna...) The suspension mechanism relies on the vertical movement of the drive input of the axle , changing main pivot point from one CV to another, allowing for each wheel's independent movement from each other. Video: Photos: Thanks for reading! -
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 :) -
After a few month break it's time to get back to Lego and Eurobricks, and why not do it in style I give you the leopard 4x4: The model is a combination of the following ideas and concepts: Quite some time ago I came up with double torque tube suspension idea and now it was time to use it in a real model Claas tyres were an obvious choice due to their agressive profile and massive size. With the release of the 42069 set, I was finally able to build a model with a unique and striking color combination The final model took me some 12 hours to build and the features are as following: - Powered by 4 RC motors and 2 Buwizz - Double torque tube suspension - Independent dual drivelines - Dual servo steering gemoetry - Working winch - Working lights - Openable doors - Openable hood - Openable and removable rear cover Specs: - Width: 24 cm - Height: 24 cm - Weight: 1600 grams - Final gear ratio: 1:5 from outermost RC motor output - Total power: ~60 watts Now onto the photos: The rear trunk can be opened: There is barely enough room left for seats in the interior. Notice the different springs used to potimise suspension. The before mentioned springs give the model excellent flex: There are two servo motors used in order to keep the steering system as stiff and strong as possible: Under the hood there is a hidden winch, which is strong enough to lift the car: And the final, most important photo. Notice how the left and right side wheel drive axles use different colored joiners and bushes: And finally there is a video of the model in action: Safe to say the combiantion of the four RC motors and two Buwizzes with a low gear combiantion of 1:5 results in a model with impressive performance. As seen in the video Leopard can wheelspin all 4 wheels when accelerating on flat surface, which is a first for any of my Lego offroaders. Dual servo motors provide massive steering power and rigidity and allow the wheels to be steered into obstacles with ease. Only downside to the model is it's slightly high center of gravity cause by all the added panels and detailing. P.S. It feels good to be back

Here's my latest creation, built primarily to put the BuWizz unit to a serious test, and look cool while doing it :) Photos & reading: http://sariel.pl/2017/12/monster-bug/ -
Dear AFOL trainheads, After almost six months of designing work, another five months of construction, countless bursts of temper, and being relieved of a small fortune, I am very proud to present my latest locomotive MOC. This time, it’s a 2-10-2T narrow gauge (760 mm) steam locomotive, class 600.76, of the Bulgarian State Railways (Balgarski darzhavni zheleznitsi, BDŽ). Basically an enlarged version of the German DRG Baureihe 99.73, the first five locomotives of the class were built in 1940 by BMAG (formerly L. Schwartzkopff) in Berlin for hauling all kinds of trains on the mountainous Rhodope railway from Septemvri to Dobrinishte. Delivering about 850 hp, the engines were extraordinarily powerful by the time’s standards for single-frame narrow gauge locomotives. They were so successful that the BDŽ were keen to acquire more, but after the Bulgarian Tsardom had turned into a communist republic at the end of WW II, it became almost impossible to buy industrial goods from German manufacturers. Thus another 10 engines were delivered in 1949 by Fablok in Chrzanów, Poland. These Polish-built locomotives were technically identical to the original Schwartzkopff ones, but could easily be distinguished from the first series by the combined steam/sand dome casing and the odd-looking smoke deflectors, which seem quite ridiculous on an engine with a top speed of no more than 45 km/h! From 1966 on, after new diesel locomotives had arrived at Septemvri, all class 600.76 locomotives were relocated to Cherven Bryag in northern Bulgaria. Several have survived until today, albeit most of them in desperate condition. One engine – No. 609.76, however, is in operational state (now stationed in Septemvri again) and regularly used for excursion trains. My model portrays a locomotive from the second series as it ran in the late 1960s, some years after the whole class had been equipped with compressed-air brake and supplementary oil firing. As opposed to the drawing, it therefore has a shortened right side tank (to make room for the air compressor), air reservoirs below the rear tank and an extended coal/oil bunker. The model is in accurate 1:22.5 scale except for the track gauge, which according to G-scale standard is always 45 mm regardless of the prototype’s actual value (as mentioned before, class 600.76 has 760 mm, or 33.8 mm in 1:22.5). Therefore, it matches LGB garden railway track and rolling stock. Dimensions and height of the coupling bars are designed in a way that they work with LGB link-and-pin couplers. Three PF L-motors working on the central driving axle are responsible for propulsion, with the other drivers (BBB XL) being coupled by the side rods, just as in the real thing. One BuWizz brick allows to remote-control running direction as well as speed, and serves as a power supply for the lights (separately switchable front/rear headlights, combined cab & running gear lights). The LED equipment was purchased from Brickstuff; valve gear parts and main rods were supplied by zephyr1934. The running gear layout proved to be quite a challenge. The leading and trailing axle are of the Bissell type and can swing out by 9°. Of the driving axles, the second and third one are blind, while the fourth one is slidable laterally by +/- ½ stud. With this configuration, the engine is running stably on straight track, yet also able to negotiate LGB R3 curves and switches (1195 mm radius). The model consists of more than 3200 parts and weighs about 2.2 kg. Enough said – enjoy the pictures! Some views of the engine frame. For reasons of stability, I had to fill the prototypic cutouts with trans-clear plates and bricks. You can see the steam inlet pipes running to the cylinders on the outside, as well as the exhaust pipes inside the frame, leading steam to the exhaust nozzle in the smokebox. Underneath, the brake rigging is also reproduced: The leading/trailing trucks. The tongue connecting the truck to the main frame is free from load, which means that it could be kept prototypically thin; the engine weight is supported by the axle bearings via the 4x4 tile on top. Fully detailed cab interior, including a tiltable ”Marcotty“ type firebox door and functional folding seats: Complete smokebox interior as well. The exhaust nozzle, spark arrestor, smoke stack bottom, boiler tube openings and superheater tubes are visible: Plenty of water in the side tanks: Some boiler details, among others showing the generator hidden behind the smoke deflectors: The combined oil/coal bunker can be removed to give access to the power button and the charging socket: The three magnetic switches for the lights are hidden in the rear toolbox: Posing in front of a historic BDŽ crest: The cab lettering: The lights: Some matching, albeit non-purist decoration (1:24 GAZ M20 Pobeda by Yatming, 1:22 [sic!] VAZ/Lada 2106 by Avtoprom)… A short video, showing the valve gear in motion. Note that unlike many conventional model locomotives, the valve stem is really pushed back and forth. A video of the engine pulling an LGB G-scale train will follow as soon as possible. As always, you can download the lxf file here. Also, more and much larger pictures can be found in my Bricksafe folder. Finally, I’d like to say special thanks to Sergio Monai, who with his fruitful feedback and proposals kept me stimulated to achieve the best possible result! Comments are of course most appreciated – thanks for stopping by! Best regards, Sven Edit: New video here! -
Finished MOC Do you remember my Reform Metrac H7X ? Reform also produces the Muli: As the project of my Citröen DS doesn’t really progresses, I do this project in WIP, to compensate. ^^ The functions will be close to the Metrac ones: 4WD with a 4 cylinders fake engine Steering with 3 modes Front and rear PTOs And I add: A pneumatic pump to add pneumatic tools Central joint (it’s only the front axle on the Metrac) Openable cab with a lever and a pump actionning a pneumatic cylinder. The best function! But this MOC will not be manual, because there is not so much room in the chassis. (I think it’s possible, but the playability will be extremely bad) So it will be remote controlled, using the BuWizz. So: Driving by 1 XL by axle Steering: 1 servo by axle. To have the 3 steering modes: a M motors controls a PFs switch -> it changes the sens of rotation of the rear servo, or it stops it. The pneumatic pump is powered by a M motor That was the start: And now I’m here: On these two pictures, you can see the rear PTO. On this side, the pneumatic pump: And here is the mecanism which allows the possibility to get 3 steering modes: The chassis is very, very compact. I think you can put an elephant on it, it will not move at all. For the tools, I think I’ll make a pneumatic arm (The pneumatic cylinders of the Mercedes truck would be very helpful, but I don’t have this set) And for the front I don’t know, so if you have ideas, tell me!

First of all please watch the teaser video from last week :) A couple of months ago everyone and their grandma tried to build an RC car going faster than 40 km/h. Although I don't have a properly working old Technic RC unit with the remote (somehow I have only faulty ones), I have the necessary amount of buggy motors and 2 BuWizz units, so I had to give this a try :) The build is not 100% pure Lego (although BuWizz is built to be used with Lego), but it still has the fun factor and of course the challenge :) The whole process turned out to be much-much longer than I expected, but at the end it was a success! I spent several weeks creating, improving and testing the car. The basic idea was to use 2 BuWizz units, 4 buggy motors and 4 Technic motorcycle wheels and to add only the minimal amount of components to remain light and fast. It had to be solid enough to survive all the crashes during the tests and record breaking attempts. I had dozens of tests at various locations until I found a proper track and the final configuration of the car was created. During this time a lot of parts had to be replaced as the axles were bent after a couple of runs, you can see the examples in the video. The car does not have a conventional steering to reduce weight. For the speed runs only small adjustments are needed, so the direction of the car is controlled by the speed difference of the wheels - there are two control sliders on the phone for each side of the vehicle. The faster output of the buggy motors is used, the gear ratio is 3:1. I tested several combinations to drive the wheels, the most successful one turned out to be the usage of 36t and 12t beveled gears. The speed was measured with the on-board GPS unit. The car was controlled mostly with my phone, but for the fastest run I was using an iPad (longer range). Even like this at full power the car ran out of range very quickly. I think it would be possible to go even faster with this car, but that would require a completely flat surface and a chase vehicle to ensure the controller stays in range. Maybe another time ;) -
The idea for this MOC came immediately when the Claas set was released. The tires were perfect. Now, I should clarify, I truly do not mean the title of “Redneck Truck” disparagingly. Also, although I am in Texas, despite my truest desires, I cannot in good conscience consider myself one with this crowd. I have never attended one of the mud-fests you see below. That is not said in defense, rather, out of jealously. The idea for this truck and the ensuing video came from watching youtube videos such as the one below and I could not help but notice how fun I thought they looked. Details of this build: - Weight: 1492 grams - Length: 43 studs - Width: 15 studs - Final drivetrain gear ratio: 7:1 (1.667:1 x 1.4:1 x 3:1) - Opening Hood, doors, tailgate - Working (fake) V10 engine - Full Suspension Really not much more to say. Truck is driven by two XL Motors, direct-coupled together. Powered by BuWizz. Steering is by one M motor. Steering motor and overall configuration are a little weird in that they are mounted very high. That was intentional. The purpose of the truck was to run in mud and water and since PF motors and electronics are not water proof they needed to be mounted high. The bodywork is a little bulky, but again, this was on purpose. I have noticed in my hours of wasting time (watching muddin’ videos) that these trucks are often older Chevy or Ford models that in real life have blockier, less-rounded bodies. So I tried to emulate that. Also, naturally, in a real-road worthy truck you would not have an engine halfway out, exposing cylinders, piston-heads, etc. Yet, Redneck Mudders aren’t really supposed to be logical or reflections of realism, so again that was all done on purpose. The engine was inspired by @BusterHaus. Fun build….. hope you enjoy the pics and video! More pics and details @ http://www.moc-pages.com/moc.php/441915 -
I had a long conversation with Roni of BuWizz fame about desirable vehicles used with his invention. Apart from electrifying large Lego technic vehicles, we were thinking about producing a simple and low-part-number vehicle, which can be quickly build and used. Well, this was the intention, however I was not very successful with this. I mean, it's not a problem regarding dimensions etc., but more of a general shape. My cars look like something from another world but not in a good sense. So, please Sariel and other well established builders, perhaps you could just skip this presentation:-) But then I have spotted Mini Mining Truck in 42055 and it seemed cute (perhaps I am a bit biased towards large models but small technic models are generally quite nice and full of features). Therefore I decided to motorized it. At first I've tried with Lego components but found out there is no room. Then I decided to use BuWizz, since allowed a bit smaller footprint. However, the truck kept growing in size. I have motorized the propulsion (I wanted to add the differential, however it kept the truck to slip while navigating rough terrain), steering and raising/lowering the dump. In addition I have also put in some lights, however BuWizz application at this moment does not support switches (hint, hint) so using lights is a bit of a drag. There are several issues I did not addressed properly: single back wheels (not enough room at this scale), not uniform color (lack of parts), cabin missing (I used the space for cables) etc. I have rebuild the d*mn thing at least 10 times but I guess this just speaks about my inability to do great technic job. Nevertheless, the truck moves and it's quite fun to play with. And I guess this is one of the main features. -
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.

Hi! Two years ago, I had made a Gymkhana with Ken Block’s Ford Fiesta. It drifted well, but I wanted to do better using the BuWizz. So I decided to make a better chassis and pair it with the bodywork of the world’s best rally driver’s car : Sébastien loeb’s DS3! This new chassis‘ works in the same way as the old version, but it’s better at drifting. First of all, a reminder of how it works: When turning, the adherence at the rear axle is decreased. This is due to the caster angle of the front axle which lifts the rear interior wheel. (Like a karting il me semble qu’on dit a go-kart mais il faut vérifier!!) So, what changes with this new chassis compared to the old version? The caster angle is the same, but the swerve front wheels relative to their pivot point is decreased (?). The rigidity has been decreased, and the transmission has been upgraded. Now, it has less friction. The consequence is that the difference of adherence at the rear axle is smoother when turning, so drifting is more realistic. Furthermore, there is the amazing BuWizz power! However, the car isn’t easier to handle. (It takes a lot of time to control it perfectly) This car has got stickers, and building instructions! Both have been made by Thorsten Spelz, so thanks to him! Click here And now, the Gymkhana!

Updating the first post to have all three RC mods in one place. 1st version - Power Functions motors & SBrick control This is a quick and dirty upgrade, it started as a test to see if 2 or 4 L motors can drive the set properly, but things escalated quickly :) The aim was to add the PF components without taking apart the set completely or to change original structure, so obviously there are more elegant ways to hide all the motors and to upgrade the suspension and the drive train. The list of the added elements: 4 PF L motors (drive) 1 PF Servo motor (steering) 3 PF M motors (functions) 1 PF switch 2 8878 Battery boxes 4 PF lights 2 SBricks The 4 L motors can drive the car, but it has no extraordinary performance due to the added weight. The servo motor is struggling sometimes (especially when the car is not moving), it'd need another servo motor or some other solution for the steering to work smoothly. 2nd version - pickup-style body, 4 buggy motors, 2 BuWizz units After the first attempt I wanted to build something faster, so I had to reduce weight and add more power :) The back part of the truck was removed, I removed also a lot of non vital elements (like the fake V8). 4 Buggy motors were added and they were powered by 2 BuWizz units. The results was pretty fast considering the tracks and could handle the obstacles well. 3rd version - tracks removed, wheels added, pickup-style body, 4 buggy motors, 2 BuWizz units This is my third and last Lego 42069 Extreme Adventure remote control mod. After the previous version I did not plan to create another one but I was convinced by some comments on my YouTube channel (thanks for the tip!). Although I really liked 42069 on tracks, I realized that the top speed was limited by the construction so the 4 buggy motors could not show their full potential. I removed the tracks and added the wheels from the 9398 Crawler set. The pickup-style body was kept from the previous mod to ensure the car is as light as possible. The axles were rebuilt completely to fit the buggy motors and the wheels. The car is driven by 4 buggy motors and there's a PF Servo for steering. It is controlled and powered by 2 BuWizz units. It became surprisingly fast, I was curious so I added a small GPS tracker to measure the top speed - you can check the result in the video :)

Good day. For a long time I wanted to create a moc with various functions apart from steering and drive. Overview: -4x4 drive with 2 diffs -3 steering modes : rear only, crab and all-wheel steering -Boom ascention -Boom extention -Forks tilting -part count of approximately 1000 pieces The forks on the end of the boom were able to be replaced with another attachment by pulling out two 8l axles with stop. The cabin has on openable door , adjustable seat and a lever to switch steering modes. The steering is a very basic type, the front stering motor is attached to a switch , which neutralizes it's movement or decides the direction of steering. the boom is extended through a pulley system , which was done due to lack of 4 stud gearracks. total boom size being fully extended is of 60 studs. The video below shows basic functionality. Something I learned with this build is that I should stick with smaller size mocs and not to rush into medium sized model. All photos here
