  1. Here is my first attempt of building a rc trophy truck: Thanks to @brickosouch for the Inspiration and sharing the stl files for ball bearing lift arms!
  2. Hi everyone, I've finished trying to RC my 42043 and it seems that the PF L motor has issues providing sufficient power to drive the set? I obtained instructions from the creator of this video (https://www.youtube.com/watch?v=BpP_05uxKqs&t=22s&ab_channel=PaweΕ‚Wojnarowski) and also checked PPUNG DADDY's 42043 RC video (https://www.youtube.com/watch?v=O8easq7ueIo&ab_channel=PPUNGDADDY(λΏ‘λŒ€λ””)-LEGOTECHNICRC), both used an L motor with no problems. Here's a video of the issue: https://youtu.be/J8P13WLPzN8. As you can see in the video, the motor loses power after driving for some time, eventually being unable to drive at all. The problem is worsened when I try to drive and steer at the same time, it's almost impossible to drive and turn. I have tried swapping the tyres around, changing batteries, trying a V1 and V2 IR receiver, switching positions of the motor and servo cables, and using a new L motor. But the problem still persists. Here's a photo of the L motor: Could it be because of excess friction introduced in the rear axles during construction? Because I noticed when I lifted up the rear axles, the motor spins the wheels at its standard rpm, BUT only 1 wheel on each axle spins, the other is stationary. Then when the wheels contact the floor, the motor suddenly seems to struggle with driving the thing. Hence I was thinking could it be that I built the differential too "tightly"? Appreciate any help from the technic experts in this forum, thanks in advance!
  3. Hi, As a winter project I'm working on a 4WD RC buggy. It will be heavily inspired by @agrof's Class 1 Ultimate Buggy, for I very much like the behaviour and the looks of that model. With this model I will also deliver to my promise to @DugaldIC to make an RC model. I was planning on finishing this MOC without a WIP topic, but I simply can't work without the feedback . It will have 4 L-motors and 1 servo motor. No buggy motors, for I will be using current-date parts only. Control will be done with SBrick. Sofar I have been working on the axles. The rear axles are very much inspired by agrof's model, but this time everything relies on perfect fits. They rely on the Pythagorean triple (5,12,13). The front axles are my very own addition to this model: 2 L-motors are integrated in the double-wishbone setup. Making everything rely on perfect fits, is one of my main challenges. The second challenge is to make everything relevant form-locked. And of course the model needs to perform. All wheel hubs are turn-table/u-joint based: Sofar I have only been designing digitally, but I did check the most essential constructions in real life already. I will show progress when ever I have something to show. If you have any comments, feel free to reply. I'm new to motorized building so I can use some feedback.
  4. Hello Eurobricker's I just wanted to show you one of my latest builds. Its an RC semi truck that has the ROOF based on a Scania Crew-cab! Love it or hate it here it is. Features Differential in the rear. Opening doors Spacious Cabin Detailed Interior Full RC L Motor and an M motor Working 5th wheel Easily removable battery box. Love it or hate it there it is. Please give me some feedback, I haven't made instructions yet as I don't know if anyone will be interested in building it!
  5. I got the 42123 McLaren and decided to build a rc version of it. Here is my actual step: It has got no suspension but positive caster angle at the front. 😊
  6. I was searching for offers on the out-door suspension and noticed that there are only two sets that include it but I only knew about the bike one. So I checked the building instructions of the 8369 set and omg what is that system? Is that even qualify(of course it does because it's Lego) as Lego? So if anyone can provide info about this strange system I would be really thankful.
  7. LetΒ΄s start with brand new model for the LEGO Technic Challenge. A 29 cm tall figure of American astronaut with moving wrists, elbows and shoulders. The helmet is equipped with two PF lights and both arms are operated by PF M motors. The model is remote controlled and powered by rechargeable LEGO battery.

    [WIP] UAZ 3151

    Hi, I am building next MOC based on model which can be found in the game Snowrunner. I picked KHAN 39 Marshall - it is based on real world vehicle - UAZ 3151. I would like to ask for your advice with one of my biggest problem in mocing - creating a decent looking body. When you see the photos and think "It doesn't look like UAZ..." then YES - you are right and: I wish to focus on body and look (I don't want to discuss functions here, they are there and they are fine). As you can see, the main color is picked (some parts in proper colors are missing, but is not a problem when bricklink is around, the same goes for some missing obvious parts), but any smaller recolors are possible. The biggest problem I have is the front grill. It looks almost ok, but as the grill for Jeep or Land Rover, not the UAZ. I tried to recreate UAZ grill, but I failed miserably. As you can see, there is no much space for it and I am also very pleased with perfect connection of the front and the hood and I definitely will keep that. Important factor is also the fact, that body needs to be as one piece, which can be easily removed, so the body demands some rigidity. Also I plan to add front and rear lights, but at first I need to be sure that the body is right. So, could you help me a little to improve the look so it would be closer to UAZ body look? :)
  9. Hello, This is my first post. I built Wing Body Truck seven months ago. Then I knew that many people wants building instructions. Now it is available. Sorry for late, because I've worked alone! Total 4126 pcs. The weight of Truck is 4600g (with 6x Eneloop batteries).
  10. This is the first non-contest MOC that I have posted. It started out as @Madoca 1977's Baja Trophy Truck. I think I originally got as far as mounting the engine when I first started. As I only have the long shocks in soft, I decided I needed to redesign how the suspension worked. I also added all-wheel drive, which significantly complicated the front end. As well as kingpin inclination. I spent a good amount of time trying to get Ackermann geometry, but could not get anything sturdy. That was almost a year ago. I shelved this project. Then my wife got me the Porsche, Claas, and a second SBrick.. And this is the result. The main frame and roll cage are the most similar to Madoca's. Since I have taken these pictures, have redesigned how the battery boxes are mounted. They attach to the frame and sit much lower into the truck. It is possible to take off the bodywork and roll cage and drive. I redesigned the rear axle so that the power sent to the front was from both sides, so that one set of l-motors was not power 3 tires. There is still some clicking in the front, but only when not driven on a flat surface. I had to reduce the gear ratio to 1:1.667. The differential at the rear acts as an adder and sends power to the front differential, and fake engine. The rear wheels are still driven directly by one pair of motors, each. I could not figure out a way, without buying shocks, to suspend the rear axle on the smaller shocks and still have plenty of travel. Until I found some small springs in my junk drawer. I have no idea what their strength is, but they get the job done. At full compression and fully turned, the front tires will touch the body. The body itself comes off in 4 pieces: each side, roof/hood, and front bumper. More pictures can be found in my Brickshelf folder at: http://www.brickshelf.com/cgi-bin/gallery.cgi?f=571486 I will leave you with my favorite picture
  11. I think, it would make sense to open a new thread for the Unimog 8110 U-400, that includes all the MOCs, changes, improvements on the Unimog. It should also contain all the new attachments, equipments, that people build. It should show their ideas and what they are creating for this cool set. I am looking forward to see your creations! I'll start today. I implemented a pneumatic driven cargo bed. It is driven by the original motorized pump and works pretty well. The lifting angle could be better. So there is still room for inmprovments. For more pictures of this MOC plesae vistit my Flickr-page or (after publishing) my Brickshelf-folder. Regards, Gerhard
  12. Hi, I'd like to share my second C model for 42099, inspired by the recently released off-road buggy. The design goals were 1) faster speed 2) responsive and long suspension travel 3) lightweight and curved shape.The wheel hubs and the differentials perform down-gearing, so I decided to apply 3x up-gearing by a ratio of 5:3 and skip the differential to make it faster than the original. Since the differentials are not used, the small gears can be used for up-gearing with perpendicular meshing of gears, which is smoother than the parallel meshing of the 20 and 12-tooth gears. I decided to use rear wheel drive only, one motor driving each rear wheel. I managed to compact the drive-train with the following setup: For suspension, I wanted a long travel and a wider wheel base, so I tried to increase the length of the swing-arms. The rear suspension seemed simple with 7L beams, but the front suspension was more difficult, as I had to increase the length of the 6L steering arms in the set by 1 stud, so I had to apply some tricky workarounds. Furthermore, I wanted a lightweight axle with a positive caster angle, with the steering motor integrated closely to the axle. The result has more than 6 studs of ground clearance and 3 studs of travel and is quite responsive: The battery is integrated into the middle of the model to distribute the weight between the two axles, and to provide easy access from the bottom. The whole base looks like this: The bodywork proved to be the most difficult to get right, since the panels available in the model are hard to use to get the light-weight frame-like body that I wanted. After taking some inspiration from the shape of Madoca's Blue Lightning buggy, I got the hang of using the arched pieces and the flexible hoses to build the curves, and used some of the panels to finish the body with a simple roof and hood. The roof is attached very strongly to the base, so the car can be lifted by it.As the small grey seats in the original just didn't feel like a match to the overall shape and scale of the model, I gave building a custom seat a try. Luckily, the few available red pieces were just enough to make a black seat with two red stripes :) I think it adds a lot to the overall look of the model.Here are a few more pics: Finally, here's a video of it in action: Building instructions available on Rebrickable. Let me know how you like it! Cheers, Viktor
  13. 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
  14. Hello folks! I am building a Chevy Monte Carlo Nascar. This is my first technic MOC on which I will be building bodywork based on a real car. The car will be using: two XL motors, one M motor, two receivers, one LIPO battery box. It will have no gearbox, and it will be based off this picture. Thank you @Sariel for having your model scaler available to the world. Cheers Let's Build
  15. I have done this MOC more than a year ago, but as for the Ford Mustang Hoonicorn, I can't make the video until the bug of the BuWizz (with the Fast and Ludicrous modes) is corrected. So I show you the pictures of the MOC for the moment. ^^ I have started to build this creation when I have received 2 RC motors. The purpose was to see what I could make using 2 RC motors and a BuWizz. So this thing is an airplane... until the bug stops the BuWizz. With the 2 RC motors connected to big wheels by the high output, this is very fast. How I had the idea to make this model? I wanted to make a cartoon / videogame style MOC, so I chose the most famous vehicle of Mario Kart videogame. The 2 RC motors are at the rear, the BuWizz is between them. At the front, there is the servomotor which activates the steering with an Ackermann effect, and there is a return to the steering wheel. The body work is easily detacheable. You have just to remove some pins, or simply to detach the blocs from the chassis. Video coming in a moment I think...
  16. After 9 month of work, I present the completed version of my latest Moc, a 2019 Subaru WRX STI It features : AWD, with lockable central differential 6+R Sequential gearbox Fornt McPherson Suspension Rear double wishbone suspension, with anti-roll bar Working fake boxer engine Opening doors (front one with handle) Opening hood (or bonnet) Opening trunk Interior with detailed dashboard Decorated engine bay Render of the gearbox : Full driveline The belly shot The interior, with some detail, such as aerations. Engine bay, made to look as close as possible to the real one : It can also be built in white, with some minor adjustments. I also created Instructions for it. The instructions are made for the black one, but can, with minor adjustment be used for the white one. The instructions are 1218 pages long, handmade with Stud.io 2.0. You can download a sample here. Or look down here. You can Buy the instructions on Rebrickable. https://rebrickable.com/mocs/MOC-38243/Toucanx/subaru-wrx-sti/#comments And of course a video : I Hope you like it. If you have any question, don't hesitate, I will try to answer quickly. After this line, starts the WIP thread. ––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––– Hi everyone, It's been a long time since I haven't posted on this forum, but today I would like to share a new project that I have started not so long ago. It's a Subaru Impreza WRX STI car that I will make. The list of what I will put in the car is the following : Awd Boxer 4 engine McPherson suspension for the front wheels IndΓ©pendant double whisbone for the rear wheels Lockable central differential 5 speed sequential gearbox I searched a bit for 5-speed sequential gearbox but I didn't found any. So I took a 4-speed gearbox design by @Rage_Hobbit (found there) and I added a 5th speed. Here is the result : You can download the .lfx. Note that you are supposed to place rubber band linking the orange pieces to the black one under the blue triangle. I have already made the boxer engine and most of the chassis. It will use these wheels : It's the one that are used in 42077 rally car. However I ran in a problem, it seems that the gearbox can not support the force involved in the transmission. The gears do a lot of skipping noises (doesn't sound healthy for the pieces). So I wanted to know if anyone knew a reliable 5-speed sequential gearbox / a 5+r sequential gearbox. That's it for today. More updates coming soon.
  17. Some time ago I've build a minimal scale control+ 8-wheeler. The shape isn't perfect, but I hope it's interesting: I hope you'll find it interesting. Also check out my channel, more cool stuff out there, I promise :)
  18. This is my very first MOC of a semi-tractor mini chassis. This RC chassis took two months of intense testing and it just 94 pieces (including PF devices) to create the best mini chassis and its mostly a simple design. This chassis will host to many of my future projects and I also created a couple of youtube videos to show off its performance and durability. Version 2.0 chassis includes center differential and suspension. This chassis it includes the following, 1/10 scale Chassis is just 94 pieces with a to create a no gear slip no tire slip thought in my design. very strong frame and durability Its very modular and basic form is 1 frame = 2 halves so both axles will have the same suspension, drive, steering, etc, etc . (I experimented with all types axles and color) (ver 2.0 120 pieces) RC build in mind (it can be used with lego's, sbrick, buwizz and lepin or even a custom rc controller) 67.8 x 34r balloon tires (Balloon tires have the best traction for all types of surfaces like sand,rocks, asphalt and excel on smooth shiny surfaces) 1 lx motor and 1 servo (you can add more motor) 2 way reverse Ackermann Steering (can be upgraded to 4 way) AWD Dual Gear drive train with 1:1.66 output with all time positraction (to reduce gear slippage) Simple suspension (1 l travel and very stiff) (ver 2.0 2 link suspension per axle 3 l travel) Fake disc brakes Fake engine (optional) Center differential (ver 2.0 only) Short wheel base with excellent handling Off road and street car capabilities built into the chassis I have included some pics and videos and will add more. it still a work in progress!! My first video is to show the performance and handling and the second video is a 5 minute off road test to show its durability and to show that I can build a reliable RC chassis. 2.0 version 2.0 version side view Version 1.7 this video is to show performance and handling this 5 min video is to show durability and I can build a kick butt RC chassis !! And yes both videos are the same chassis!! Please add your comments and if you have any question, please feel free to ask about my MOC. This chassis was a really interesting project and discovered a few things about Lego's color of their beams and lift arms. I did a search on this forum about color and weight and none has came up so I guess ill be the first to post this.. I discovered that not all beams and lift arms weigh the same.. Same with pins and axles. I know there are friction and friction less axles and connectors but what I discovered beams and lift arms also weight differently, For example: This dark gray weighs 1.726 grams and Red of the same shape weighs 1.68 grams!!! That is a difference 0.114 grams!! yes that small but with 94 pieces it can add weight , The more I use the red Lego bricks colors, the more lighter the model !!! I have weigh a lot of different parts and color but I don't have all colors and shapes. So far the red color bricks are the lightest in my collections and that means using red bricks will adds more performance !!!! yes you can pat me on my back for this discovery!!
  19. Hello guys, Im new on the forum. I have a problem wich is very annoing, it is my recently purchased buggy motor. I have built a rally car and when i bought the motor, i only needed to click it in to place. Now, the problem is that if i drive (drift actually) the overload protection comes in and brakes the party. Wat i am using is this: 1. 8878 Li-Po Battery box 2. V2 Receiver 3. On the blue one, M Motor for steering, just like rm8's Black Mamba GT 4. On the red one, 8886 extension wire 5. From the extension wire to the Buggy Motor 5292 I have trouble uploading pics but i will try to figure out.
  20. Hello, I got back into Lego during quarantine and decided to try something unique in the holiday theme. Here's my driving, spinning, Christmas tree. The top part is made with three turntables, with rotation driven by motors at the base. Frictionless pins and/or axles allow the "branches" to raise or lower with centripetal force. I know it's ugly, but I was aiming for a freaky vibe so that worked out Here's a short demo, with some videos of the inner workings too: View from underneath: Side detail closeup More photos: https://www.flickr.com/photos/191824083@N05/with/50858767061/ Happy to hear your feedback and design tips. I lurked this forum for a while and learned many building tricks.
  21. I am building a RC version of the Lego Land Rover Defender (42119) and it will include a 3 speed sequential Transmission. It will be operated from the Powered-Up Lego app. using 3 buttons and it includes a dial that shows the selected gear. I am using a Technic Hub (88012) and a Technic Medium Angular Motor (45603). The Remote Control has 3 buttons; up-shift, down-shift and neutral. When the application is started it calibrates the shifting axle to be at the "neutral" gear and sets the angle to 0. Pressing the up-shift button will engage the 1st gear, then if pressed again the 2nd until it reaches the 3rd gear. If you press the up-shift button more times it will not move the shifting mechanism but will make a "clanking" noise. Pressing the down-shift button will sequentially shift to the next lower gear until it gets to neutral where again will make a "clanking" noise trying to go lower. To the right of the 3 buttons there is a dial that indicates the gear is selected. [Media]
  22. Here I've created my first attempt at a RC 3 speed gearbox allows you to change gears up and down using a power functions remote control. The gear changing mechanism is implemented using two parallel axles each with gears arranged in such a way that shifting one of the axles to one of three possible positions meshes the gears with 3 different gearing ratios. The gearing ratios implemented are 3:5, 1:1 and 5:3. The gear shifting axle is controlled by a lever mechanism driven by the 4 state stepper from the bugatti chiron set. This mechanism in turn is driven by a medium power functions motor activated by the remote control. Hope you like it.
  23. It's been some time since I provided an update on models from my Turbo Racers vs. Police Interceptors series here, most (22 cars + variations and a "dyno") are on Rebrickable now: https://rebrickable.com/mocs/?tag=10127&include_accessory=on&include_bmodel=on&include_subset=on Because the models I want to present today are not strictly racing, I thought about starting a new thread for them: TG Power wrecker This is a wrecker truck based on a modified body of the F A H R T-Laster with the following functionality: Selectable AWD/RWD (propelled by RC Buggy motor (Chinese replica installed ATM), steering by PF Servo motor, power and control by a BuWizz 2.0) manual front winch manual rear boom (closely based on the one from the 42079 B model but with manual double winch) rear PTO (motorized by PF M motor) rear towing hitch Colors are not final yet, e.g. the currently red boom mechanis will become LBG. This wrecker is pretty fast. I experimented with the new diffs to make it stronger instead, but I couldn't avoid gear slipping with a 12z bevel gear against the 28z bevel gear of the rear diff when driving it perpendicular. The propulsion motor then sat half a stud higher but was still only kept in place by pins and could be pushed up over time. Do others perhaps experience gear slipping with the new diff when driving it with a 12z bevel gear in perpendicular fashion? Can this work reliably at all? This video shows an application for the PTO, i.e. driving a small car lift: Car transport trailer This features: double winch at the front for pulling cars onto the platform (can be driven manually or from a PTO) tiltable platform (using two small LAs, manually driven) extendible ramps Except for the coloring I consider it pretty final. Hope you like it.
  24. Hello I'd like to present my small-scale RC semi truck. It has PF Servo, XL motor and sbrick mounted in the cab/frame and the battery is neatly mounted in the trailer that also has a two-stage ramp driven by single L motor and Technic strings. The cables go through the hole in trailer saddle (big turntable) to connect sbrick with battery and ramp motor with sbrick at the back of sleeping cab. Full gallery: https://imgur.com/a/2uPHku There is an alternate configuration for potential standalone/without trailer use: Hope you'll like it :)

    Brushless Buggy

    This buggy contains a 3600KV brushless motor (2838). It has a pinion made from a LEGO axle and it runs a seriously good working drive-train. Together with the new 42109 differential and a (new?) 2D suspension method it turns out to be a fun car to drive. Please watch a video here. Especially the suspensions are worth having a look. More and more I'm using custom springs to create all sort of applications. Useful and useless. Almost useless is the spring-lock to open the hood. Very useful are the long front springs and the two-dimensional rear springs. Please let me know your comments. No building instructions available yet. If there is a need, let me know.
