[MOC] Greyhound 4WD RC Buggy /w instructions - Improved rim-hub connection
Didumos69 posted a topic in LEGO Technic and Model Team
I would like to present the result of my Winter-project. A big thank you to everybody who supported me in the corresponding WIP-topic and of course to @DugaldIC for challenging me! Instructions are available on Rebrickable. Features: Turn-table-based wheel-hubs with minimal slack 4WD by means of 4 L-motors powered by two BuWizz 2 units Fully independent suspension Steering with Servo-motor 30 degree steering angle with Ackermann geometry Caster angle Fake V8-engine driven by M-motor Can handle a rough ride Liftable by roof, nose and tail Everything in-system Stats: Parts #: 1844 Weight: 1980gr Length: 54 studs Width: 35 studs Height: 23 studs I hope this will pull @Blakbird back into Technic . Some stills from video-material. And finally a few short videos. -
The American Club Racing (ACR) model was introduced in 1999, starting with the Viper GTS (Phase SR II). Exclusive 1 by lachlan cameron, on Flickr This model had suspension and engine enhancements focused on maximizing performance in road racing and autocross environments. Horsepower was bumped to 460 hp (370 kW) in these models, while torque increased to 500 lb·ft (678 N·m). Weight was reduced by over 50 pounds (23 kg) by stripping the interior and removing other non-essential items such as the fog lamps (replacing them with brake ducts). Dodge Viper ACR by lachlan cameron, on Flickr In an attempt to stay true to its heritage, I've left this beast without bells and whistles in the name of speed.It sport a front clam shell hood, opening rear trunk, and spring back doors. The real catch here is in the speed and options. Dodge Viper ACR by lachlan cameron, on Flickr This Viper packs 2x Buwizz 2.0 (with Ludicrous mode) that power this monster directly to 2x Buggy motors. The gearing is accessible and can be swapped for a higher or lower gear in minutes. Ratios avail: 1:1 and 1:1.7. This model also has many build options: 1. 1 or 2 buwizz / 1 or 2 Lipo / 1 or 2 Sbrick 2. 2 Buggy motor or 2 XL motor 3. Fully manual car (just remove the electronics 4. Swap out the engine on the fly for a new one! Dodge Viper ACR by lachlan cameron, on Flickr The Viper also has a rake to it that I also replicated. 1 stud off the ground at the front, 2.5 studs at the rear. Dodge Viper ACR- open hood by lachlan cameron, on Flickr Its been a pleasure playing with this car OUTDOORS (don't even think of play indoors, I smashed it over 10 times) and I hope you guys enjoy the video!

It's about a time, since I've been ended my dark ages and now it looks like my way will be rather smaller attempts and "projects", then bigger and more sophisticated ones. My older builds had their own topics here and here, but I don't think that all of my next builds will be suitable for separate topics, so I decided to make this one, where I have intention to add all of my publishable builds. And for the beginning, here is my wip small manual buggy. Buggies are favourite Technic builds, there are many of them in all sizes, shapes and qualities. This one is intended to be small and simple, all manualy working. Now it has front and rear suspesion, openable cabin, steering and rear wheels conected to fake engine. I'd like to improve rear axle suspension, add HOG and steering wheel and some details here and there. And finaly adjust color scheme, although I'm not very disturbed with this clor vomit in this type of vehicle.

This is what happens when you have a dune buggy but want it to be a salt flat racer or even a dragster. Very fast and very durable, performs astonishing wheelies and looks as scary as a golden-toothed-and-cheap-sunglasses-skull-adorned racer could get. 42046 C-Model, uses 100% of the original set's parts and has those notable features: ► pull-back motor ► very fake V8 and exhausts behind the cockpit ► steering wheel, speedometer and floodlights + rear lights ► reinforced frame and balancing enabling it to perform wheelies (apologies for the photo quality, those were the best results I could get) EDIT: Here's the LDD file if someone's interested. Couldn't assemble the whole thing because of the usual LDD shenanigans, but it's kinda straightforward when you go those three pics. That orange bulky thing is, of course, an equivalent of the pull-back motor not included in LDD - shoutout to marco9999 for the design. http://bricksafe.com/files/Immo/42046_C_Model_Draggy.lxf

Hello there! I used to have lots of bricks when I was a kid, but I left them at my parent's when I moved. Now that I have kids and nephews, I'm happy they can enjoy these when visiting their grandparents. On the other hand, that left me with very few stuff to build from. Now, when I want to build something new, I usually spot a set with interesting parts and start from there. The goal here was to build a fully suspended car with steering, differential and motor. The build had to be tough enough so my youngest (under 2 y.o.) could play with it. I bought set 42075 because it had a differential and nice panels and started from there. I lacked cardans, so the transmission has to go through a cascade of gears, making the rear train a bit bulky, but it works! I had a couple of spare motorcycle coils left from a 42036 set, which themed the build to a buggy. There, that's all for my first post here. Cheers!

[WIP] Greyhound - 4WD RC Buggy with BuWizz 2 - Redesigned wheel hubs
Didumos69 posted a topic in LEGO Technic and Model Team
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. -
Hello to all technic fans. Since I got a BuWizz, I always wanted to make a buggy car. And here is the result. My concept buggy from KTM The inspiration for the design came from the original concept of KTM AX buggy. It is not the same look and design, it was only ispiration for my build. It is driven by 2 PF L motors geared up with 20 to 12 gears. It is rear drive with diferential. Steering is with 1 PF servo motor. Lights are 2 pair of PF LED ligts. It is fully independent suspension. I also made a lifting roof for easier access to the BuWizz box for charging and switching. Due to its low weight it is very agile and fast. It is realy fun to drive with this litle buggy. Realy big thanx goes to BuWizz for this briliant magic box, and also respect to mister imurvai for his briliant solution for game controler. And the video. Thanx for reading and watching. Best regards, Valter

Lego Tehnincs for me started with 42000 set. First step to own creations was small B-model modification Then I started to create my own creations. At that time I didn't even knew about other "sick" peaople and forums like this. So, as a first post, littlebit about what I have created until now. First creations was only from parts of 42000. First creation was some trike (or something like this) with font wheel drive Then there was (street)quad

Let me introduce you my latest alternative model - Dune Buggy built out of set 42075 (First Responder). This buggy is my tribute to two special sets: 8829 (my very first LEGO set) and 8048 (the set that definitely ended my dark age). It features front axle steering, rear axle suspension, V2 fake engine and opening cab cage same as original models. I wanted to add differential but it would make engine block too high so it has just "one wheel drive". I hope you will like and any comments are welcome.

[MOC] Ultra 4 Crawler Buggy - Tested, final release!
agrof posted a topic in LEGO Technic and Model Team
Hello All! It is winter time, so I am bit more busy on Legoing. After seeing, that @Didumos69 started his 4x4 buggy project, I looked into a bit deeper the Ultra 4 racing, and the rigs been driven in this extreme events. Finally the video, what I linked to his topic, triggered the work on another MOC: the Ultra 4 buggy. Here is another video to see the interesting bits of independent suspension system on this beast: Still, I might end up with IFS (independent front suspension) and solid axle with torque bar for the rear, but the body is heavily inspired by the Lasernut buggy. Parameters: 2x L motors 1x servo motor AAA battery box - in order to be replace ability with BuWizz in case IR control Let's look at into the progress a bit, maybe it is interesting to read. I started on 28. november with LDD model. To set the proportions, and the body ideas, I usually place the essential parts free in space first. Check the real inspiration thing and the very first sketch: After that I added the electronic parts, to check the necessary minimum space. (Unfortunately Stud.io has corrupt models, so some cover parts of the motors are just not present.) At this stage, I built the front axle, to see how can I integrate the steering. The answer is: massive fail. So back to drawing table, I deleted the 5x7 frame, and started to figure out, how to connect the needed fixation points for swingarms, servo. Due to this, the model gets more complex than I thought, but buildability is always first! I recommend to check meanwhile IRL building too, or at least stop by and thinking about how to add the related parts. I was hopeing for a simple MOC, but I ended up already a pretty complex assembly, so I made each step with double check. Later on, I will try to add groups in LDD to represent the buildability order too. So far the front module with steering and IFS is ready, the middle module is almost done, I am wondering about interchangable solid axle or independent solution for the rear - not sure yet. Also the color is to be decided yet, as the springs type as well (soft or hard). I think if soft ones will be OK, than I go for white body, as it presents the "rollcage" better. In case the yellow hard shock absorbers will be needed, of course the only choice is: full MEAN black body. This picture shows the advantage of the white body, and also a comparison for tyre types: 3740 on the left, 45982 on the right, both on 56908 wheels. So far 407 parts, and I guess it is about 70-75% ready. I need to figure out how to fix the roof, and create a solid, but easily disconnectable rear module. Necessary parts are ordered, so real build pics might come in couple weeks first. And how is the road presence? I guess it will be pretty much like a punch in the face. p.s.: Yet another WIP, I hope for long winter nights, to finish at least some of my unfinished projects... -
[MOC] 42077 B-model (Buggy) color mod and enhancements (with instructions)
Mylenium posted a topic in LEGO Technic and Model Team
I've made some improvements to the B-model of the Rally Car set (42077), the sand buggy. Most notably they make the model much more sturdy, which could be useful for adding a motor/ RC functions. Downloadable instructions are included, so it should be easy for you to implement those changes. If you have any questions, just let me know. Check out the article and download on my blog: https://myleniumsbrickcorner.wordpress.com/2018/07/06/rigid-green-and-black-42077-b-model-moc/ Here's a preview of the instruction booklet cover: -
Greetings, ladies and gentlemen! I'm glad to introduce you a modification of @Didumos69 Greyhound buggy Yeah, "Mad Max" inspired vehicle again First idea was just "increase durability and add some crawler abilities", but result exceed all my expectations. Adding planetary gear reduction 4:1 to all wheels increase offroad capabilities to sky high (keeping in mind perfectly working suspension of original) And final step - I decide to prepare for summer offroad Lego event in Moscow and for future festival, so I reworked exterior in postapocalyptic style. Other photos Here is LDD model of front hub with planetary gear reduction I used in my modification. Rear hub is done similarly, except for black connectors to suspension arms and without U-joint. Bonus: video from "King of the Hammers" race event in Moscow and photo from "Summer Brick" Lego festival in Taganrog, Russia Thanks to @Didumos69 for his amazing buggy and instructions, and also to @Shurik & @VerSen for cool photos! Hope you like this rusty piece of metal!

I mainly build Technic C-Models, but I also enjoy Creator alternatives, so here's what I built out of set 5763. In the photo, hot-rodder sigfig is added for scale and reference). Features: ► minifig scale (with adjustable steering wheel) ► openable and adjustable canopy-cage with roll bar ► rear suspension (individual for each wheel) ► details such as engine with radiator and twin turbo, lights, steering wheel, twin exhaust and rear view mirrors Browsing through OLX (online marketplace fo classified ads) I found old (2011), used 5763 for a price of a new small, ~50 piece set. I liked how the set contained big wheels and offered possibility to build suspension, so I bought it right away. Only one super-cheap plate was missing, so it was a nice deal. The MOC Alternative uses almost every part from the set. As you can see, the build came out quite clean:

Hello! I would like to present my first MOC, which i was tempted to build since a while. I was always more a "fan" of Class 1 buggies ( https://en.wikipedia...i/SCORE_Class_1 ) over Baja trucks, and I also couldn't find any LEGO versions of them, so i decided to build... and failed, built again, and failed..., built again, and so on... The long travel independent suspension with driving was really a challange, finally I found a solution, which works... kinda. I reached my goal, to make this thing move, but I must admit, the driving performance is poor, as the suspension arms are still not rigid enough, so the rear wheels start to lean. It moves, but not what i would call: clear run. Still, i thought, maybe it is worth to share, because the rest of the car is OK. I also would like to inspire others to build such MOCs, i would be happy to see more (and better performing) unlimited buggies! Building instruction (V3): here And now... the pictures (edit: no more video will be made, lack of patience and knowledge) - fixed: EDIT: as updated version is available, old pics and video removed. Pre version pics added. V0 - sketch model: V1 model with XL motors - not really good performance... V2 model with L-motors: Update: V3 is ready - see page 2. A clever patch by @Didumos69 for the rear swingarms, now they can not disconnect at all!

For the "Fast car competition" organized by BuWizz, I have done that: For this contest, you have to make a vehicle with suspensions, and do a video showing it doing at least one jump. Of course, the MOC must be powered by a BuWizz! For the steering, there is a servomotor. The driving is done by two L motors, with a 1:1.8 ratio. So the buggy has a correct speed, and enough torque to be driven on dirt, sand... It is fully suspended. The front is an ordinary system. But for the rear, I couldn't do independant suspensions (not enough compact) or a suspended axle (because as the motors are in the chassis, when you accelerate the axle tilts). So I done an "amost suspended axle". The liftarms thin 5L have an effect of anti roll-bar. I have tried to do a light design. Thus, the MOC weighs 460 grams.

[MOCs] Compact CUV and Blue Lightning Buggy
Madoca 1977 posted a topic in LEGO Technic and Model Team
Hello everyone! It's been a long time since I posted last creation. For the past few months, I've had difficult life situation. I was away from any LEGO-related activities. I did not build new MOCs. I abandoned all WIP projects and just built a wall around myself... I am so sorry, Jantjeuh and rm8. I deeply apologize for having troubled you! In March, I started walking slowly. Soon I recognized that I had to work hard to get back Madoca into my mind. Here are the results. I built two MOCs. Honestly they are mechanically simple and have nothing innovative. Instead, I aimed to achieve both playability and detailed look. I hope you will like them. Please give me a chance for resurrection. Video: CUV Buggy Building instructions and additional pictures: https://plus.google....64977943/albums Rebrickable: CUV http://rebrickable.c...977/compact-cuv Buggy http://rebrickable.c...lightning-buggy Compact CUV It was mainly inspired by red Range Rover Evoque, but finished model is not an exact copy of it. Do you think which actual SUV looks similar to this MOC? I used dozens of newer parts (mostly pins) which were released in 2014 and 2015. So it can be called AWD SUV 2015. Features: All-wheel drive and front wheel steering 2 L motors for propulsion, Servo motor for steering 2 pairs of LEDs for headlights and tail lights Independent suspension on all wheels Working steering wheel and V6 engine Openable hood, doors (with locking mechanism), tailgate, glove box and armrest box:) There are four 12t tan bevel gears on drivetrain. They all survived after two hours crawling. Like blue Buggy, this drivetrain didn't cause breaking gears. My concern was that 3L axles might slide into CV joints. Eventually all four 3L axles moved half-stud into CV joints. But they surprisingly kept holding each 12t black double bevel gears despite the connection became weaker. I thought it's OK because I didn't see any lack of torque or speed. You can see its performance in the video. If you want to avoid this axle movement, you need cutting parts and, A. using 3.5L axle. B. putting 0.5L axle (or flex axle, pneumatic hose, hard hose...) into CV joints. Blue Lightning Buggy It is my Buggy#3. The concept was simple: to build another buggy using different drivetrain from its predecessors. Configuration of motors is the same as Buggy#1 & #2. This time I adopted independent rear suspension. Then I tried to build efficient drivetrain which needed to be nearly the same as direct-drive (#2). Features: Rear wheel drive and front wheel steering 2 L motors for propulsion (one per each rear wheel), Servo motor for steering Long travel independent suspension on all wheels Front axle is placed at positive caster angle Working steering wheel In this setting, L motors never broke bevel gears. Now I want to know if powerful SBrick version would perform well without gear cracking. -
I started making a regular Renault Twizy... Twizy 3 by James Tillson, on Flickr ...but with the buwizz and a buggy motor I switched to Twizy F1, Twizy F1 4 by James Tillson, on Flickr Shame its not yellow but the yellow #4 connectors are more expensive than white ones.

Hey guys! It's been a little while since the last build, but I've got a new model. This time it's a class 1 offroad racing buggy like the one in the DIRT2 video game. It has servo steering and two RC motors powering it. Suspension on the front is double wishbone, and rear is trailing arm. My main goal was to make it fast, sturdy, and look good, and I feel like I got a pretty good balance. The only drawbacks are that the steering isn't very precise, and the IR receivers don't get as much reception as I would like outside in the sun. Still, it was a lot of fun to film, hope you guys like the video. Enjoy!

Hello, I wanted to introduce myself with a few favorite mocs of mine. I discovered Lego technic a year ago and I love it. I had something similar when I was a kid, called “Constructor”. It was the same principal as technic beams (only the Constructor’s beams were half the width of Lego’s), connectors, plates… and used M4 bolts and nuts to connect instead of bushes. So I built tractors, trucks, cranes, trailers, etc. I started building my creations out of Lego in LDD because I don’t have real Legos, and I enjoy it very much. I built a bunch of them in the last 5 months. So far I published my creations on LDD gallery website, but that site went to shit, so a few days ago I transferred on rebrickable. I very recently discovered this community so I thought I share it here also, with you. Anyway here are my mocs in LDD, I hope that’s ok. https://rebrickable.com/users/pagicence/mocs https://bricksafe.com/pages/pagicence Mercedes Actros SLT Mercedes Arocs Crawler V2 Nooteboom Multydolly Nooteboom Euro Low-Loader Mercedes Arocs Timber Truck (mod) Volvo FMX 8x8 MAN Modular Truck Rock Crawler Black Buggy Naked Street Bike So, how did I do?

VIDEO: Current Version: ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ Old Post: Hi! I have decided to enter the TC13 contest and here is my entry so far: It has suspension on both axles and a working V4 engine. It looks a little funky right now, but I am thinking of how to change the front for the better. It has the modern pullback motor in the back. Please give me any advice you have. Back:

[HELP] Serial Numbers on Buggy-Motors and RC-units
TechnicSummse posted a topic in LEGO Technic and Model Team
Hey guys... while disassembling my newest purchase 8366 RC Supersonic Racer, i was pretty much surprised, when i looked at the serial numbers of the rc-parts. As you can see in the following images, there is the same number on ALL 4 electronical parts (each motor, the RC-unit and the remote). RC-unit motor 1+ motor 2 remote At my first 8366-set there was a different number on each part, as you can see in the following images: rc unit motor 1 motor 2 remote Does this mean, that my first model was put together from different sets? Or did they simply mix the parts at a special date of the production? Also i see a 5-digit serial number on one of my additionally bought motors, wich also includes a letter and not just numbers. Another special thing about this motor is the motorcover on the side, as you can see in the following pictures. I guess the 5-digit one is the newest, maybe out of a 8287 Motorbox-set, or a 8421 Mobile Crane-set? seperatly bought motor serial number 225K8 serial number 6292, 3282, 1263, 5383 Does anyone have more detailled information about all this? -
Everything started here thanks to @Leonardo da Bricki front axle and front part was pretty easy. Very challenging was to build narrower (by 2 studs) rear axle with differential and really independent suspension, but somehow I managed it As the result there was rear axle with uutput/input to top or front. Some work in progress And the ens result: some RWD buggy street legal (because of lights) HOG steering and working steering wheel, with possibility to put on right or left side independent suspension on all wheels mudguards moving together with suspension on all wheels boxer type 2cyl engine I'll try to fit 4cyl inline engine later. Now It seems, that should fit.

Sorry if this goes somewhere else, but I have a question for buggy motor owners. Do you think $100 is a good price for 2 buggy motors, a rc unit, controller, rc unit suspension, and cables, is a good price? And @mocbuild101, @Marxpek, @jam8280, and @TechnicSummse, you may have a new challenger soon... If I get the lot...
