  1. 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. You can see a demonstration, parts list and instruction for the C1 on my youtube. C2 and C3 instructions will be added to the OP when completed.
  2. 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
  3. 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.
  4. 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!
  5. 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 :)
  6. 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
  7. 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/
  8. 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
  9. 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!
  10. 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 ;)
  11. 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
  12. 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.
  13. 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.
  14. 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!
  15. 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 :)
  16. 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
  17. Good day. This is a trial truck using 1 XL motor for drive, 1 M motor for steering and powered by BuWizz. The drive is powered through a worm gear to 8t gear, creating a powerful 1:8 reduction. It uses model team wheels , they don't have the best perfomance, but it is good enough. For the bodywork I was inspired by ГАЗ-66 (gaz-66), although it isn't an exact copy. Both doors can be opened, the seats and steering wheel are adjustable LDD model available here: download
  18. Hello My ripsaw, inspired by Fast Furious 8 (but not a copy). Since Buwizz can handle 2x Buggy motors, I decided to build light and powerful tracked vehicle for snow. Vehicle for fun! Movie was filmed 3 month ago. We have summer now. TURN ON ENGLISH SUBTITLES I am not the first here with such powerful tracked vehicle. I can confrim that it is useless toy and hard to control. Thing for fun:) more photos http://bricksafe.com/pages/rm8/ripsaw Thank you for watching!
  19. Good day. This used to be one of my prototypes for the e formula competition. But after making the chassis I decided to put a BuWizz in . Backstory: "This is one of the best known racing cars on Xerox , developed by Xewyz Industries. Stabilized Zirum Crystals' energy is used to power it , obtaining constant and (almost) infinitely lasting power. It has a turbo system to increase the output speed." Real statistics: -2x m-motors for drive , with a 3:1 gear ratio -1x m-motor for return to center steering -BuWizz Using (underestimated now) m-motors , it picks up quite high speeds and is a lot of fun to drive around ,even in normal BuWizz mode. Here is a LDD model -> download A quick preview of what to expect whe the full video is finished: https://www.youtube.com/watch?v=GaVM6J2oFvI
  20. 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. (Click on the image to play video) As always, you will find larger versions of the images in my Bricksafe folder. The LDD file is available for download here, yet doesn’t show the final design of the cab roof. Comments are of course most welcome. Thanks for stopping by! Best regards, Sven
  21. I'd like to share with you my upgraded version of the 42050 Drag Racer. First of all, 2 videos: I really liked the look of the 42050 set when I got it, I think it has all the main characteristics of a drag racer. On the functions' side I was not that satisfied, there were a couple of issues: - Simulated wheelie mode looks ok-ish while the model is standing, but it's really lame when you motorize it - official motorized version has manual on/off, you have to walk with the model to stop it. If you add an IR receiver steering still remains manual - M motor is weak to power a vehicle that supposed to be fast :) - Driver seat is small for a Technic guy, minifig fits but that's really out of scale The upgraded version has the following features: - body panels and stickers from 42041/8041 Race Truck - Servo motor for steering - 2 Buggy motors - 2 BuWizz units for maximum power and more weight - 1 M motor for powering the fake engine - Proper seat for the driver - Larger spoiler to add weight to the back – essential for the wheelies 🙂 I am quite satisfied with the result, the upgraded version is fast and most importantly it can do proper wheelies :) A couple of pictures of the build: I also built a drag racing Christmas tree for the videos. The Lego LED lights are controlled by 2 SBricks. The staging/start sequence is pre-programmed, I did not have all the necessary components to build a proper functioning one. I'll add some information and images later if you're interested. You can see some more pictures and additional information in my blog post
  22. Hi! When I received my BuWizz, I wanted to make a fast RC model. It had to be very light, so a kart was good to make that. The mechanic is very simple. There are just some gears to turn the wheels at a high speed. As you can see, the driving is powered by two L motors and the steering by a servomotor. According to the tyres, this kart is very fast!
  23. Good day! About a year ago I made an APC . It was a simplistic, underpowered MOC. Today I present you my second attempt at building APC. It was slightly inspired by BOV m11 Functions: -4x4 drive with buggy motor with 1:4.4 gear ratio -steering with m-motor -turret rotation with m-motor -gun elevation with m-motor -powered by a BuWizz -pendular suspension on rear axle The off-road perfomance of the geared down buggy motor was surprisingly good , both at low and high speeds. The turret can rotate 360º freely with the motor geared down 1:2.3. The gun uses a mini LA for the elevation @ 1:1 gear ratio The charging port and the switch on the BuWizz are accesible throught the hatch on the left side of the vehicle. I hope my studded bodywork isn't too horrible , the video will be up later today.
  24. Hi everyone This is a model i built a while ago, but only now had the time and eqiupment to showcase. I was asked to build a Buwizz showcase model for a toy fair in Boogna, italy. After some thought I decided to combine the rare dark blue panels from 41999 with tracks and a couple of RC motors. The finished model has following features: 2 RC models for drive Spring supported pendular suspension Two working fake V8 engines - hence the V16 Rollcage reinforced interrior with 4 seats Openable 70's muscle car style openable bodywork A working winch LED bar powereed by a total of 10 LEDs So lets start with a 360 view of the model: As you can see the body is inspired by 70's muscle car styling with large chromed grill Detailed view of the grill with the cute bunny: Lifting up the body exposes the internal rollcage and the two massive engines: Further the rollcage can be lifted by pulling out the two red pins, showing the 4 identical seats, making this a perfect family car The two V8's are powered by the RC motor's faster output: The power passes via cardan axles under the seats and up the gears: In case the model ever gets stuck there is also a functional winch powered by an M motor via 1:5 gearing ratio: The suspension is highly flexible: And here is the most important photo of any technic model : And to finish up with a bang here's a video of the Ripster in action: A quick summary of my thoughts regarding this model: Because the tracks are powered by the RC motors directly this is THE fastest tracked model I ever had the pleasure of building. But that speed comes with a price, the model has problems steering on spot on surfaces with high friction such as carpets. Sudden acceleration on such surfaces with quite a heavy model like this (1,5 kg) can cause problems with tracks coming apart. For that reason this is a perfect vehicle for smooth surfaces or ice. It is also very good at drifting, though it takes a lot of coordination to control a tracked vehicle like this. Suspension is extremely durable, the wheels were originally held with frictionless pins, but that proved insufficient, so they were replaced by axles 5 with stops. After that upgrade I had zero issues with suspension and it proved to be very flexible, yet reliable. Biggest problem with the model is the cosmetic stuff, the V8 chains tend to slide off after a while at such high RPMs, the bunny likes to jump into oblivion and the front grill can fall apart when crashing into stuff. Oh and one last thing, ITS LOUD. Driving this on my floor sounds like machine gun fire, so I hope my neighbours wont file a complaint . At the end of the day even with its positives and negatives its a very fun model to drive around and that is all that matters.
  25. Good Day. I present to you my biggest MOC ever - a futuristic dakar truck. This is a project I have started back in February to make it in time to the arrrival of BuWizz , or that is what I had planned. For propulsion it is using only one buggy motor , what isn't the best idea because the motor ends overheating. But it is possible to install a second buggy motor with a bit of chassis re-design. To fill a bit the huge truck, I installed a X16 engine- courtesy of ZBLJ. The steering uses 1x m-motor , without any return-to-center mechanism thanks to the precise control with the BuWizz brick. The outside design was heavily inspired by 00's sets ( specially 8466) , and I included gull-wing doors with mini linear actuators . m-motors can be installed easily to motorize that function too, but I used two knobs on top of the cabin . The interior was kept simple - two bucket seats and a dashboard. I already shoot some footage , so a video will come soon. For now , here are some photos. 2017-04-30_05-28-06 by Alaxaf, on Flickr
