[MOC] X-MARXX 8rc, 8 buggy motor and 4 BuWizz rc car
Marxpek posted a topic in LEGO Technic, Mindstorms, Model Team and Scale Modeling
Hello all here is my latest build, inspired by the Traxxas X-MAXX 8s remote controlled car. The idea was to build a car as "compact" as possible while using 8 buggy motors, 2 for each wheel to give it decent power, as you might notice the buggy motors are at a 90 degree angle from each other, this is to prevent them sticking out the front and back, the chassis needed tall shock towers anyway so it was a nice fit. The front suspension and steering is built fairly sturdy, however crashing with this power, you can brace all you like, it is just going to break as you can see in the video.. The newer type cv-joints are used at the motor end, but since i did not want to use the new hub with its reduction, i used the "old" cv joints with the hubs, and yes, it does "eat" the joints and/or the hubs when something is not sitting correctly. the front has a dampener, a large thin pneumatic actuator, normally hidden by a panel, it is shared with both sides and does.. very little.. but is was fun to integrate. The front springs are from the 8420 motorcycle, adjustable in stiffness, but less stiff them most people imagine them to be, these just seems to fit the build, sadly i didn't have more yellow ones for the rear. The steering uses 2 servos, not only to give it more torque for steering, but also to help reduce the slack from the gear rack to the 12z gear, The two 12z gears on the rack are both offset by 1 tooth, but against each other, the long axle going to the servo's are under a bit of stress but nothing serious, it really helps reducing the slack on the steering. To further prevent slack from the hubs they are steered with the front links and stabilized the rear links, the next picture shows the 2 gears on the same rack (car is upside down), you can also see the imprint of a 5L axle from the bumper on the 5x7 frame after a crash.. The rear suspension has the same drive setup, but since it is more fixed and less likely to get damaged in a crash, it never destroyed any joints or hubs, here i also integrated dampener in the form of small pneumatic actuator on each side, which again.. do very little.. but was fun to integrate, it also has a torsion bar going from one axle to the other to prevent body roll, let's just say it was fun to integrate :) The grey springs are the exact same as the yellow ones, but these come off the Lego 8369 rc "dirt crusher" set, i happened to have these 4 spring, considered to get 2 more yellow ones, then i saw the price.. and went with mismatched colors.. so please forgive me i cheaped out... The body started out as a crawler body, and got heavily modified, extended in every way, added 4 seats for Technic figures and a new color scheme, It is fully detachable with 5 pins. The front and rear lights are in the chassis but they line up perfectly with the translucent bricks on the body, making it easy to get to the buwizz for charging or turning them on. The video and pictures have some inconsistencies in them, i know.. but i have had 3 horrible crashes, that required rebuilds plus some roadside repairs here and there, some i forgot to give the proper fix later on.. shooting the video took me a bit longer because of the same reason, i need to practice my driving skill... or not go to a skatepark when it is wet... or just not build in overkill mode... Thanks for reading! if you have questions or comments, feel free to ask of course! Marx. -
For an exhibition I made a small Corvette-scaled car with an RC motor powering rear wheels. Powered by Buwizz, that model turned to be totally uncontrollable, with epic amount of oversteer at low speed and underster at high speed. So I got an idea. Why not make a 4x4 version of a miniature car? My worries were that the added complexity needed to power the front wheels will increase the complexity, weight and reduce the performance... But I decided to give it a shot anyway. The first version used a chain drive to front the front wheels from the rear axle, but that was soon scrapped due to the poor strength of the chain. So after replacing the chain drive with an axial driveline, I came up with this little, yet powerful model. The front wheels are an older 49,6 x 28VR type which use softer rubber than the rear ones. This way the car tends to oversteer less: In the rear DUAL 49,5 X 20 are used to give it as much traction area as possible: The bodywork can easily be removed to expose a torque-tube sytled chassis and a simple interrior: A servo motor steers the front wheels via a rack. Maximum steering angle is around 22,5 degrees: 3x11 panels are used as the main chassis, giving the model very high rigidity, while keeping the weight low: According to LDD the model is made of less than 400 bricks, less than to the upcoming 42109: The front wheels are powered directly by the rear axle via 20:12----12:20 gear sequence. There are no differentials, since the model reaches high enough speeds for wheels to understeer and slip in the corners anyway. Technical specs: Length: 25 cm Width: 14 cm Height: 10 cm Weight: 575 g Theoretical top speed: ~18 km/h Even with 4x4 drive, the racer still powerslides all 4 wheels even in just the normal mode, as you can see in the quick and drity slo-mo gif I made: I was pleasantly suprised by the amount of control you get with the added FWD. No longer am I at the mercy of the rear wheels to stop the car from crashing into a wall. Accelreation is of course much better, making this one of the fastest accelerating models I made. Oversteer has been reduced, but there is still plenty of power left to powerslide the model with all 4 wheels spinning. Stay tuned for a proper video showing off the performance soon.

I'd like to present my latest BuWizz creation: I like to think of it as a tribute to my beloved 8366 and 8475 sets, which I never get to play with, because i need their motors for other projects, projects like this..It also explains the somewhat cheesy name of the car.. This is a 8475 / 8366 hybrid on steroids and the most fun i have had with an RC car in ages! Here is the video: i hope you like it!

Considering the BuWizz 2.0/PF Set, Any Thoughts?
StudWorks posted a topic in LEGO Technic, Mindstorms, Model Team and Scale Modeling
I have only been building my creations with EV3 but for a long time now I thought about getting a BuWizz. It's a good price right now. I'm really interested in how amazing this product is and I would be excited to make the transition to PF/BuWizz powered cars, so I have to get a servo motor and a few L motors to go with it. What is your opinion on buying a BuWizz 2.0? What PF parts should I buy to go with it to make car MOCs? Thank you for your feedback. -
MOC: 1:33 Hohenzollern 0-6-0T v2.0 - UPDATE with new features
Sven J posted a topic in LEGO Train Tech
EDIT: Model's latest revision HERE! Dear train community, a while ago, I presented my model of a small industrial shunting engine (for information about the prototype, and to compare the pictures below with version 1.0, please see here). However, although it proved to be a strong and reliable little locomotive, I was never entirely happy with it: The roof turned out to be very flimsy, and the battery box and IR receiver were completely blocking the view through the cab. So when BuWizz was announced, and I realized that its height would be considerably lower than that of 84599, and it would need no additional receiver, I thought I should give it a try and rebuild my MOC (even though this meant that I had to get a smartphone… ). The revised model has been completed for a couple of weeks now, but it wasn’t until last week that a BuWizz app version was released which allowed to control two output channels via one slider, so I couldn’t let the engine run until then… (By the way: One more thing that I would really wish for would be an option to „lock“ the slider in a given position, so that you don’t have to keep your finger on the phone all the time when the engine is running. Maybe someone from BuWizz will read this… ) Following alterations have been implemented: - BuWizz replacing the rechargeable battery box - boiler diameter increased by one plate for better scale accuracy and a brawnier appearance - slightly larger, smoother side tanks - revised colour scheme without black striping (thus adding to the stouter look) - additional small windows in the cab front - completely redesigned cab roof with more prototypical profile and no longer needing transparent plates to support the door openings - handrails below the buffer beams for the shunting men - strings as sand pipes - improved shape of the cylinders - smaller headlights - (at least rudimentary) cab interior thanks to the reduced height of BuWizz But unfortunately, still no opening doors – sorry, Sergio! (I promise my next model will have them. And it will be a BIG model. REALLY big!) With BuWizz set to „slow“ mode, gentle and precise shunting becomes possible; something one couldn’t even dream about while using Lego’s IR remote control system. As always, you will find larger versions of the images in my Bricksafe folder. Comments are of course most welcome. Thanks for stopping by! Best regards, Sven EDIT: Model's latest revision HERE! -
HI, I wonder if anyone has some experience with using buwizz with Lego trains? I am attracted by the small form factor and the opportunity to design profiles, but over 120 Euros is a lot to risk without asking advice here ...

[MOC]Lego Suzuki Jimny Sierra
filsawgood posted a topic in LEGO Technic, Mindstorms, Model Team and Scale Modeling
Hi everybody! Half a year ago, the Suzuki company released a new generation of their famous mini SUVs - Suzuki Jimny and Suzuki Jimni Sierra(Wide edition). I, as a caring lover of this particular model, tried to repeat the same thing in Lego. That's what came out of it Specifications: 1:10 Scale All wheel drive 1.55 DC Chequired flag all terrain A/T tires (copy of BF Goodrich A/T KO2) Solid Axles Constant rear diff lock The modular design (body and chassis are separate elements connected by 6 points. The body and chassis, in turn, consist of smaller modules - doors, hood, axles etc) Electrics: BuWizz brick (or AAA Lego battery box/LiPo unit + IR V2 Reciever/Sbrick) – battery and receiver 2L motors - movement Servo motor – steering 2 LED lights iOS/Android smartphone/pad with BuWizz app – Remote control Life’s too short to stay stock! Therefore, in this model I use tires DC CHEQUERED FLAG All-Terrain T/A (87x26x1.55), that are an exact copy of BF Goodrich T/A KO2. This gives the model more realism and improves off-road performance compared to original tires. For the same reason, I recommend to using alternative power sources, in this case BuWizz, which significantly expand the functionality of the model, reduce its weight and increase the power of the motors. At the same time, the design of the model allows the use of original Lego batteries (AAA or LiPo unit) together with the V2 receiver of Lego Power Functions More photos and building instruction you can find on my personal blog page Video review: -
[MOC] Reform Muli T10X
Anto posted a topic in LEGO Technic, Mindstorms, Model Team and Scale Modeling
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! -
[MOC] RC Small Red Roadster
syclone posted a topic in LEGO Technic, Mindstorms, Model Team and Scale Modeling
Welp, back onto 1/15 scale Made this little thingy in about 12 hours after Madoca's small supercar popped up in my YT recommended. BRICKSHELF (whenever uploaded) As with my Mini Nitro Menace, this year's Corvette wheelbase was taken as a base - should be compatible with the transporter truck - and so the build began. Of course, drive&steering has been done a million times already so this needed a cherry on top - the roof was what I was looking for. Making a chassis was dead easy with the slim wheels and by motorising each rear wheel independently, the need for a differential was eliminated. Thanks to the placement of the BuWizz in between the rear wheels, steering and roof motors could now populate the central tunnel and be hidden under the black 3x11 curved panels giving the interior a "cleaner" look. Now, bodywork ain't my strongest point, but I wanted it to be ferrari RED. This meant working with a very small inventory (for me) most of which you can see on the car Of course ricer butterfly doors were made to make it look cooler than it is. Have a nice weekend, Cya) -

[MOC] RC Police Motorcycle (futuristic)
syclone posted a topic in LEGO Technic, Mindstorms, Model Team and Scale Modeling
Good Day. Got inspired to build this after an in-game motorcycle from Honkai impact 3rd Original idea was to use 2x XL motors, but it was boring af. Next obvious step were buggy motors - allowing an approximate speed of 10km/h. It could probably pick up a higher speed with BuWizz 2.0's Ludicrous mode, but fast mode of BW v1.0 is enough to topple the bike over when taking high-speed turns. Unfortunately it does require "training wheels" to ride straight, as it would lean on one side without those after taking a curve without those. The bike does feature rear axle suspension, and small wheels have shocks as well. "01" stickers reused from MPATEV, "police" from 42047. Design-wise it belong to the same "universe" as my spaceship and racers - an Axos Police bike used to patrol within city high-speed tunnels and surface operations. Video&photos, C&C very welcome and appreciated))) Cya later! -
[TC16] Hex rover
Zerobricks posted a topic in LEGO Technic, Mindstorms, Model Team and Scale Modeling
For Mission to Mars I decidd to build more of a classical machine - a six wheeled rover. I was heavily inspired by the upcoming Mars 2020 mission (https://en.wikipedia.org/wiki/Mars_2020) and wanted to integrate a drone inside the model. First thing to build were the foldable Rocker-bogie suspension arms, which is unfolded with pneumatics Each bogie featurs a steerable front wheel which is steered using a worm gear mated to a small turntable. Drive power is carried through the turntable to the front wheel. The rear wheels are on their own bogie and are driven by a combiantion of Cv and universal joints: A longitudinal differntial is used on each drivetrain which allows for the speed differences between front and rear wheels when steering. Differential is especially required when steering at 90 degree steering angle, since the rear wheels do not turn at all. A driven differential is used to level the both sides of the suspension arms: Differential allows for the movement of suspension and keeps the body leveled. A single M motor is used to adjust the leveling angle via a worm gear. Suspension in action: In order to unfold the rover, a pneumatic compressor was installed near the front of the body: The same compressor also powers 4 small pneumatic cylinders which open up the tops sides of the rover: A large actuator lifts the base of the 3D camera (placeholder for Wi-Fi camera) on the top and reveals the propeller "drone" inside the rover: Since most rovers include some kind of an arm to dig and check samples, I decided to equip mine with claws. They are able to pick up and lift with the use of a single M motor: And finally the rover can launch the propeller drone using an RC motor powered by BuWizz: Here is the final wrap up of the features and characterisics: 38 x 25 x 15 cm when folded 41 x 25 x 57 cm when unfolded Weighs 1800 grams Powered by 5M, 2L and one RC motor Controlled by 2 BuWizzes Independent all wheel drive with longitudinal differentials Rocker-bogie suspension Pneumatic unfolding Raisable 3D camera arm - placeholder for a WiFi camera Leveling mechanism Drone launcher Working claws Unlimited steering angle And a quick video of the rover in action: -
[MOC] Bugeye RC racer
syclone posted a topic in LEGO Technic, Mindstorms, Model Team and Scale Modeling
Good Day. Continuing my futuristic series of racers (Ximos , Xonox & Azimus) is this one - popularly called "Bugeye" in Xalax races - Scarab in 1:10 scale Features: BuWizz v1 2x Buggy motors RWD independent suspension m-motor with return to center working steering wheel detailed 1:10 openable canopy light up power core and "dashboard" Overall this was just a filler build with very basic chassis that served as a test platform - bucket seat with actual driver, front suspension with only one shock (part #48912), independent suspension built around buggy motors. This was as well an excuse to use some "new" Bionicle parts on a build and SILVEEEEEEEEEEEEER!!!!!! In the end it turned out OK, but steering was somewhat weak leading to a crash into my pet roomba effectively destroying the car (driver was okay so crash safety test passed?). Incomplete LDD file (the chassis and seat is there, only missing bodywork, power core and steering wheel/dash assembly. download Bonus: Crashed car and fuming driver. Cya later! -
[MOC] RC Audi S3 Quattro with BuWizz
T Lego posted a topic in LEGO Technic, Mindstorms, Model Team and Scale Modeling
After a long and difficult builing proces, the project is finally done. The project started in early may, when I created a WIP topic here on EB. In the end, I set the bar a little bit too high as I was not able to get all the desired features inside. Audi S3 quattro Specs: - Dimensions: 44x19x14 studs (L x W x H) - Weight: 1300g - Estimated part count: 1800 parts - 4 PF motors Features: - Opnable doors and bonnet - Ajustable seats (2x HOGs) - All wheel/quattro drive with three differentials (2x PF L motors) - Steering (PF Servo Motor) - 4 Speed sequential gearbox (PF servo motor) - BuWizz 2.0 Power - Complete detailed interior with no mechanics/electrics visible I tried to use as many panels as possible which is IMO essential to get the best looking bodywork. This model consists of 45 technic panels. The stepper mechanism (located underneath the roofspoiler) used for the gear shifting is increadibly simple and works very well. The chassis is very stiff. the car can easily be lifted from the roof without damaging anything. To open the bonnet, you need to tilt and pull it at the same time. The LBG pin/axle connector slides trough the 5L axle with stop when you pull the bonnet. This system was necessary, beceause othewise the bonnet would have interference with the dashboard. Like in most of my other builds, I pay a lot of attention to the interior. I never want mechanisms visible or motors inside. You will find many details in the interior, like a handbrake, steering wheel, gear lever and door handles. When you pull the red part in the center up, the buwizz turns on/off. Too bad that the center dail which is placed upside down though. The seats can be ajsuted forwards and backwards by rotating the tan 20th gear. It is a very simple setup consting of a few gears, a worm screw and a 1x7 technic gearrack on which the seats are mounted. The building proces may be very interesting to read (if you have not seen it yet). Many interisting ideas and suggestions were posted that are not shown in this model. For instance, it should originally feature (air)suspension, but due to the airleaks and absence of differentials, it couldn't take corners propelry enough. Thanks to everyone who helped me with this build! You can check it out here: I wanted to make a video of it today, but my buwizz onstantly cut off power so give me a few more days... I won't make instructions, beceause I am busy working on intructions of another model which I will show this year as well. I hope you like it. Comments, feedback and constructive critisism are as always highly appreciated! -
[WIP] Audi S3 quattro 1:12 RC - finished
T Lego posted a topic in LEGO Technic, Mindstorms, Model Team and Scale Modeling
Yes, yes yes... I am going to build another Audi After a very good result of my previous Audi, I thought with those design parameters I can't make a better car. Therefore I wanted to do something different, yet similar. I am going to scale up (slightly), and add a bunch of new features. I also realised that performance of the result won't be comparable to the previous one. The main reason for that is, that I am not going to use buggy motors. I recieved many questions like: "can I build it without expensive buggy motors?'' . I will be using these wheels: https://www.bricklink.com/v2/catalog/catalogitem.page?P=41896c04#T=S&O={"iconly":0}. I want the car to be 19 studs wide and have a wheel base of around 25 studs. The design parameters are: All wheel drive (quattro) with a central differential and without diffs on the axles. Front and rear independent suspenion. 50-50% (or close) weight distribution Servo steering (perhabs with steering wheel) Driving using two L motors 4 speed sequentail gearbox (servo operated) A good looking bodywork that reflects modern Audi's A good looking interior without any electronics/mechanisms visible Funcionality does not compromise for aesthetics (previous version is a great example) BuWizz power I allready have made some progress on the front axle. This is the result of many hours of puzzeling. It meets the requirements mentioned above. The buwizz is located behind the front axle and underneath the future dashboard. Axle for driving runs underneath the buwizz. I used these parts for the steering rack. It is connected to an eight tooth gear. On the same axles sits a 16 tooth gear which connects with the 20 thooth gear connected to the servo. The turning radius is great. I used these parts to stabilize the CV joints The next step will be to design the gearbox and rear axle. They will be integrated to save space. Comments, questions and feedback are highly appreciated! -
Hello all! I recently bought myself a BuWizz 2.0 and I've been experimenting with transmission designs using the new Chiron shifting bits and gears. I'm trying to figure out how to control a servo with the BuWizz unit in such a way that it only has full left, centered, and full right as options for a 3 speed transmission. The closest thing I can find is the light buttons in the control setup, but they only allow for center and full lock in one direction. Has anyone figured out a good way to control a servo like this or found a clean way around it? Thanks!

[MOC] Mini RC Nitro Menace (8649)
syclone posted a topic in LEGO Technic, Mindstorms, Model Team and Scale Modeling
Having finally set free the buggy motors from TC16, it was time for something speedy again. Having seen the new 2019 transporter, that scale got me again, so making a car "compatible" with that set was very interesting. And having 8649 box on display made it clear which one I wanted 2 make. After a day of non-stop building this abomination somewhat resembling the original was born: The build was based off this year's Corvette wheelbase - 20x15 studs. 8649 has oversized wheels, giving it a cartoony apperance, but that wouldn't work for this one as space in the rear was required for a double buggy motor setup. Low profile tires in combination with old rims were a perfect tuner combo and gave resemblance to the 68.8 six spoke wheels. This also allowed to place the rear wheels much closer to the buggy motors using a non-standard 36z - 16z gears combo (1:2.25) with half-stud on-axis offset [see picture below] powered through the slower, outermost motor output to an approximate 2000rpm to the rear wheels. This gear combination resulted quite reliable when braced properly and withstanded all crashes, slides and racing that was thrown at it. In contrast, the front axle is a real mess. Having to place the m-motor right after the BuWizz made it really weak, and the flex axles make it hinge forwards. It does stay in place though due to all the bracing, so good enough? Also low-pros are amazing for drifting, which makes this vehicle very enjoyable to play with . Bodywork-wise it is NOT a "modern beauty" but carries the approximate lines of the original model. All the interior details are present - double NOS bottles in the rear, Red bucket seats and a tuner steering wheel (RHD version for some JDM powah ). Supercharger was a no for me - it looked terrible on the original. Big a$$ exhausts were kept to annoy the neighbours In the end it is not fully compatible as it probably wouldn't be able to drive up the ramps, but does drive cool. Welp, here's the video and LDD file https://rebrickable.com/mocs/MOC-26855/syclone/mini-rc-nitro-menace-8649/ Best Regards, Dan. Cya later!!! -
[MOC] RC Excavator powered by BuWizz
Anto posted a topic in LEGO Technic, Mindstorms, Model Team and Scale Modeling
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! -
Lego Rocket Crawler with SBrick and BuWizz
PunkTacoNYC posted a topic in LEGO Technic, Mindstorms, Model Team and Scale Modeling
Hey Eurobricks, PunktacoNYC back again with another rock crawler! This time it's called the Rocket Crawler and it is my largest, fastest crawler yet. Youtube video: Features: - 4 L-Motors for drive (one per wheel) - Ackerman steering with custom virtual pivot system to maximize steering angle - Rigid, triangulated 4-link suspension with 100% Lego-legal original, extra large links - Very minimal, light bodywork, and a cute rocket atop the cab - BuWizz for extra power and SBrick for a great custom control scheme - RC4WD 2.2” Bully Competition Tires The initial inspiration for this crawler was twofold; I wanted to build a RC competition super-class-like crawler, what with giant relative wheel size, slim body, and high articulation. I also really wanted to make use of RC4WD's quite large Bully competition tires. This project has been in development for over a year thanks primarily to issues with the front axle. The problem with the front axle was that Lego universal joints simply could not handle the high torque required to spin such large tires. I tried using custom Lego universal joints custom dremeled brass remote-controlled boat u-joints, and even knob gears at the pivot point - nothing worked. So, I mounted the motors directly to the wheels, all within a virtual system to move the steering pivot closer to the center of the wheel for a better turning radius. There is approximately 90° of articulation between the front and rear axles: Easily adjustable suspension height: (high) (medium) (low) The chassis: Wheel comparison: Concept 1: Concept 2 (later): This has been my favorite project. Let me know what you think. P.s. I got a snupps page (nice idea, Sariel): https://www.snupps.com/punktaconyc -
[MOC] Audi RS1 concept car (donut car)
T Lego posted a topic in LEGO Technic, Mindstorms, Model Team and Scale Modeling
Hi everyone, perhabs some of you remember my first post on eb: Audi rally car. Soon after I posted it, I realised that I didn't like it enough. Therefore I decided to create a brand new version with roughly the same DNA. The main goals for the new version were to look better and drive better compared to the old one. To improve the looks, I went for a classic collor scheme: red body and black roof. I also downsized the width (17 stud compared to 18) and the wheelbase (two studs shorter). To get some more contrast, I put blue racing stripes on the seats. Making the car smaller meant I couldn't use some tricks used in the old one, such as BuWizz inbetween the front wheels. It is now located underneath the trim. To improve driving, I decided to use two Buggy motors rather than one and put them as low as possible in the chassis for the best COG. The gear ratio is the same as before: 1:1. The steering is also much smoother and has almost no backlash. Due to these improvements the car drifts WAY better then the old one. It even does donuts. Here you can see some pictures of the drivetrain and rear suspension. Due to the insane power from two buggy motors, gears often slipped during the development. A simple but effective solution I came up with was to use knop gears rather than 12t bevel gears to transfer the power to the rear wheels. The car features, like the old one, front and rear suspension, but it is a very different setup. The front now uses traditional suspension arms and the rear is a liveaxle without diff. The doors and bonnet can be opened manually. Because there is no battery under the bonnet, there was a bit of space for a fake V6 engine made out of knop gears. More pictures can be found here: https://www.bricksafe.com/pages/T_Antonie/random/audi-rs1 In case you think that the car is slow, that is due to the fact that I am a NOOB driver. In all the video clips BuWizz was in normal mode. You can watch the video presentation here: I'd love to know your thoughts and critics or other feedback are highly appreciated too. -

[WIP] Le Mans Racers
JamesJT posted a topic in LEGO Technic, Mindstorms, Model Team and Scale Modeling
This started as a mini GT40 but decided it wanted to be something else... It has a buwizz and a L-motor geared up 1:3. I'm going to make one more with a changed livery and then maybe try the GT40 again.

[MOC] RC drift car
syclone posted a topic in LEGO Technic, Mindstorms, Model Team and Scale Modeling
Aircraft ain't my thing, dumb ideas are Basically rear end was a concept from 2016, rebuilt it in october last year as I wanted to test whether a counterweight placed in the rear of a vehicle would help with "drifting". Of course, this was paired with the best lego motors (2x mythical buggy motors), BuWizz (1.0 ) and not the grippiest floor tiles, producing a very fun experience (donuts, 180° turns, and if lucky, something resembling a drift). The steering department was done with a M-motor RTC-ed by a hockey spring as always. Controlled using the beta BuWizz app, which was a nice experience and luckily suffered a lot less connection issues than the older counterpart. Bodywork. Tough department. Looking back at it, could've done a better job on the front, but wanted to try something different to classic bionicle eyes. Was able to place 2 Technic figures inside tho. The video was thrown together today (3 months after finishing ) so as to finally dissasemble this thing. Any additional pics will be in the same Brickshelf folder.
