Parts list used in the MOC is listed so you can opt to just buy the required parts instead of buying set 42100.Motorized features include: Tank drive for both tracks Arms upward/downward movements Head turn Head tilt Body tilt Manual play features include: Upper and lower eye flaps can be moved to show facial expressions. Finger movements. Limited manual arm movements Here's a link to the YouTube video to showcase its movements: RJ's Johnny 5 YouTube Video If anybody is interested, building instructions are available at Rebrickable.
  2. RC Rock crawler. Features AWD drive without differentials using 69730 "Large angular position motor"(As it has realy good torque), Steered by L-motor, and springless suspension (concept by superkoala). Lack of differentials gives nice off-road perfomance, but the crawler has big steering radius due to that.42114 C-model. You can buy instructions here: https://rebrickable.com/mocs/MOC-81106/mic8per/42114-rock-crawler/#details Video:
  3. Hello everyone and welcome to my newest C-Model. I'm keeping my current momentum of doing conventional vehicles from a tracked set and it's amazing how versatile the 42095 set can be. I call this MOC "Dirt Devil" because it was meant to run on dirt roads and has an agressive look. Now let's talk about the vehicle itself. It is 25 studs wide, 35 studs long and 14 studs tall. One of the l-motors available on the set is dedicated to steering, which has return to center functionality by using a common rubber band. There is no need to specify a size for the rubber band because it can be twisted as needed, it just needs to have enough strength to push the steering mechansim back to its center position, you can test this as you build it. Another l-motor is directly powering one of the rear wheels, so this is a 1RWD vehicle. I usually go with this approach because this set lacks parts to build a decent transmission mechanism, so, to power the two rear wheels, i would need to spend too many parts and would have enough left to model the car. Another issue with this set is that it is a tracked vehicle, so there are no rubber tires, which means the wheels on this car are useless on smooth surfaces, but if you've built my other MOCs, this shouldn't be a surprise. It runs fine on rough terrain though. Anyway, there are several fixes for this issue. Since you're getting a rubber band for the steering, you might as well get some more and hack them into the tracked wheels like i did in this video of my other MOC here; or you can add rubber studs on the wheels if you have them; or simply swap the tracked wheels for any other rubber tires if you have some spare ones, this is hands down the best and quickest solution. For anyone interested, building instructions are available at rebrickable.
  4. Hi, I think 42099 is a nice starter RC set of the PU line, so I set out to test what else can be brought out of all its parts. I'd like to share with you my set of 5 alternate builds from it. It has been a great exercise for experimenting with different options for suspensions, drivetrains and bodyworks, testing the versatility of this medium-sized set. In the end, all of the alternate models came out with quite different shapes, suspension techniques and motor/gearing setups, and I think I even managed to use those large turntables in some interesting ways. During my builds, I found that the set has a good array of structural elements, of course good drivetrain components, but is a bit limited on gears, axles and body panels. Nevertheless, once you get used to it, more configurations are possible than you would think :) Here are my builds in chronological order. Much more design details and images of each are accessible on the link behind each name. Here I shortly summarize the features and the differentiating factors of them.1) JeepyThis model was inspired by the release of the Jeep Wrangler set and its pendular suspension using the small turntables. - Pendular suspension using large turntables, both front and rear- 4WD slow drivetrain for good climbing, separate front and rear drive- Jeep-like exterior, focusing on the shape of the hood and the grill, plus the roll-cage 2) BuggyInspired by the release of the RC Buggy set, with this model the goal was to test how fast the the two XL motors can be geared up, along with creating a slick bodywork. - Independent long travel suspension with longer swing-arms both front and rear, high ground clearance- Fast up-geared rear wheel drive, independent for left and right wheel without differential- Positive caster angle at the front axle- Light-weight curvy bodywork, custom built seat 3) BeastyThis model aimed to test the possibility of building a live axle rear suspension using the large turntable, along with coupled motors for a stronger drivetrain. - Live axle rear suspension with push-rods for extreme articulation, independent front suspension- 4WD drivetrain with coupled motors driving both front and rear axles, adjustable gearing- Rough exterior, minimalistic interior 4) QuadroThe goal of this model was to build something other than a car, and to experiment with an unconventional motor setup. - Independent front suspension with positive caster angle, trailing arm rear suspension- V-engine built out of the joined drive motors, rear wheel drive- Functional steering rod- Chubby bulldog-like quad shape, bullbar 5) TrophyWith this model, I wanted to push the live axle possibilities further, creating long soft travel using only the short springs, and to find a sweet-spot in the up-gearing of the motors. At the same time aiming to create a larger-looking bodywork with the limited array of panels. - Long soft travel live axle rear suspension, independent front suspension- Rear wheel drive with motors built into the rear axle, independent left and right drivetrain without differential, faster gearing- Trophy-truck like exterior with curved front and long tail, imitated spare wheel All models can be controlled with the stock Control+ App, and the batteries can either be directly accessed from the bottom, or can be removed after detaching a few panels. All models are available separately or in a 5-in-1 pack on Rebrickable. I hope this makes you value your 42099 sets even more :) Let me know what you think!

  7. This is yet another C-Model for the LEGO Set 42095 "Remote-Controlled Stunt Racer". This time around, i challenged myself to use the available parts to build a war tank as closest as possible to the real, generic vehicle. I used the smaller sprocket wheels on purpose to make this model run slower to better resemble the real thing, as the original set doesn't have gears to adjust the velocity. It is powered by the 2 L-Motors, it can go forward and backwards, turn left and right as needed. The front is clear to easily overcome obstacles; on the rear there is a space dedicated for cable management. I tried to keep this build as compact as i could. It may not seem like it, but this was quite the challenge, it went through various revisions and parts optimization until i became happy enough with the result. It can be further improved and modded with additional parts, but i wanted to keep it as a C-Model, so i was restricted by the set's available components. Building instructions available at https://rebrickable.com/mocs/MOC-65285/davejsp/rc-cyber-tank/
  8. This vehicle is an alternative build aka "C-Model" of the LEGO set 42095 "Remote-controlled Stunt Racer". This one draws inspiration from my other MOC, the "Desert Racer" in the sense that it runs on conventional wheels and has return to center steering. It uses a single l-motor to power one of the rear wheels and the other l-motor is dedicated to steering, which returns to center automatically by using a common rubber band. It's actually an improvement over the version used on the "Desert Racer" MOC, which can be found here, because it performs the same while being more compact and taking way less space. Can you believe it fits under that hood? Building instructions available on rebrickable.
  9. Welcome to another alternative model of the LEGO set 42095. It's surprising the flexibility this set has, which allows the creation of very different models. This is a three-wheeled beach race buggy, powered by the two l-motors available on the set, each one drives one of the front wheels, allowing the vehicle to go forward, backwards, turn left or right, and do 360ยบ spins; talented drivers can also do drifts. The design is simple and aerodynamic, it has adjustable windshield and rear spoiler; side doors that can be opened as well as the small trunk behing the driver's seat. Other small features include a non-functional steering wheel, side mirrors, engine exhaust and small headlights. The cockpit serves as cable management for a clean look and the battery pack is very accessible if you need to quickly change batteries; the IR receiver is disguised as the driver's seat. The fun factor of this buggy is high and obviously tied to its uncommon three wheels configuration which will require some level of skill to drive. Building instructions available on rebrickable.
  10. Hello , I finally bring the instructions of the last alternative to 42022, the truck. Remember that the original idea is not mine, at the end of the post is the video of his creator The original video Instructions: http://bricksafe.com...Truck 42022.lxf
  11. This year has seen me move away from Technic C-modelling into using system bricks. In between the various lockdowns I picked up quite few Friends sets to C-model due to their very low price per piece on the second-hand market which gave some good practice. I saw the Velocity Racers set on my only trip to the Lego Store this year and the part balance made me think this set had a lot of potential for alternate builds, so I picked up a brand new copy (on sale). Having quite a few Technic pieces in the box, helped with my decision. Over the few months since then, I've managed to produce three different C-models using only the parts in set 71709. I'd share with you this collection of Velocity Boats, Fighter Plane and Trike. The race for the Key-Tana can now take place by land, air or Sea. Also Hauser can now put a bit more of a fight, having some vehicles of his own rather than just a hoverboard. Velocity Boats: Velocity Fighter Plane: Velocity Trike:
  12. Hello all. Here is my LEGO interpretation of a circle-track dirt Modified, which is popular in the United States. Several similar versions of them race under different sanctioning organizations, the most popular being IMCA and UMP. The car is a C-model of the 42039 "24 Hours Race Car", and thus uses only the parts from that set. 21 studs wide between the hubs, 23 at the widest part of the body, 50 long, and 14 high from the center of the wheels. Has the fake V-8 engine mounted toward the front, but fully behind the front axle, as in the real vehicle. Front suspension is independent double-wishbone, similar to the A-model's design. Rear suspension is a reasonably accurate approximation of the live-axle 3-link with panhard bar that is used in many (but not all) of these cars. Uses a "hand of god" style steering with the finger knob on the roof, but is also connected to the working steering wheel in the left-hand-drive cockpit. Thanks for looking!
  13. C-Model for Creator set 31085 (Mobile Stunt Show). An oversized hot rod for stunt shows, spewing fire, going fast and loud and getting some nice air time after jumping from ramps. Features: - individual suspension for each wheel (hard front and softer rear for crazy landings) - minifig-scale cockpit with steering wheel, gear shifter and mock gauge - small but openable and functional trunk (set's wrench would fit, or maybe two pizzas?) Pictured is the render of exact .io model of the physical build (aside from the rubber band for the rear suspension) - I don't have enough space and proper lighting to make some good photos.
  14. Hi all. This is my RC Buggy, a C-Model build of the 4x4 Crawler set from several years ago now. After building the crawler most people want it to be faster, and with the original B-Model being the exact same drivetrain I thought I would build something to cruise around the house on flat floors. The buggy uses a much simpler drivetrain, rear drive with the two motors mounted transversely across the rear axle, with only one pair of gears each. One motor drives each wheel, eliminating the need for the differential. The motors face the same direction to avoid the use of a PF switch. Front suspension is independent a-arm type with decent travel. Rear is live axle swing arm. The buggy is much faster with the buwizz, of course, but I was pretty happy with the performance of the standard LEGO parts. https://rebrickable.com/mocs/MOC-47375/Cfachini/rc-buggy-9398-c/
  15. Dear all, With the arrival of the new Volvo set, I felt like rebuilding my old 42030 front loader. The problem was that I still had a MOC built, standing in the cupboard since 2016 :s So I finally built some instructions for it (available at Rebrickable), and made a short video. Here is a presentation. The C-Model is a Jeep-like car (with Volvo colors ;) ) As the A model, it is fully motorized. The L and XL motors are connected to the transmission, and the servomotor ensures the steering (with Ackermann geometry, and working steering wheel): The two driving motors are connected by a differential, which allows combining their rotations. If we note x = 220 rpm the speed of the XL motor and y = 390 rpm the speed of the L motor), we can emulate 4 gears: L forward, XL backward: V = y - x = 390 - 220 = 170 rpm, XL forward, L off: V = y = 220 rpm, L forward, XL off: V = 390 rpm, XL forward, L forward: V = 390 + 220 = 610 rpm. The differential is also connected to a V6 fake engine, and the rear axle is pendular: Finally, the M motor is used to power a crane: Here is a small video to show it in action: Hope you like it!

Have a nice weekend!
  17. 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.
  18. This model was the result of a choice I had to make. I could either come up with an entry for the Eurobricks small car contest, or I could enter the TLCB Lockdown Competition. I really didn't feel inspired to make a small car, so I went with making a C model. I chose 42098, largely because of the fact that it was the only set I hadn't started to mix into my large collection. Initially, I was going to build some kind of wheeled vehicle, but then I hit a real builder's block. At that point, I was looking at the small wheel arches, and thought that it looked kind of like the bottom parts of an attack helicopter cockpit. After I realized that, I made the cockpit section, and got going from there. This helicopter is ultimately a nonesuch, and combines design elements from a number of real and fictional helicopters, including the Hellhound helicopter from Patlabor 2, and a design I found on Deviantart called the Fujin, which was designed by MeganeRid, The rotors spin, obviously, but they also have collective pitch control, which was very hard to implement given the parts available in the set. 42098 includes a shockingly small selection of gears and other technical bits, so I had to get very creative. The rotors are at their lowest position in this picture. The collective does not use a turntable, but instead uses a brick built solution that hearkens back to the very first Technic helicopter, set 852. The actual control for this function is a lever with a red bushing, on the right of the photo. This is the blades at maximum pitch, which better shows the collar that is used to simulate a swash plate. The second most major function is the complex landing gear. A 12z gear at the end of both wings controls this function, which uses worm gears to prevent the gear from collapsing. The first pic shows the gear retracted for flight, the second and third show the gear down for landing. The last set of functions relate to the gun pod, mounted under the fuselage. The pod can be traversed 90 degrees to either side, and will clear the landing gear towers. This is controlled by a 12z gear located behind the air intakes. The gun will also elevate from horizontal to almost vertical, using a knob on the back of the pod. An underbelly view, showing the gun pod, as well as part of the rotor drivetrain. The rotor is spun by the 2 12z gears on the tail. The gun pod, up close. The rubber connectors on the forward fuselage are actually a travel lock, and can hold the gun in place when not in use. Maximum elevation. Or is this depression? I can't decide how you'd define this. On the tarmac. The landing gear do work, but I also built a stand so that this heli can be posed as if in flight, with the gear retracted. Some up close pictures: This detail is actually important. As most of you have probably noticed, this helicopter has no tail rotor, and is not coaxial, so what gives? My vision is that a real version of this helicopter would use a NOTAR system, which uses a ducted fan to effectively replace a tail rotor. That's what the large vents on the tail are supposed to be for. Now, in terms of scale, this model is quite large. CamelHog the hedgehog and Spam for scale. One last beauty shot: The color scheme may not be very military, but I'd chalk that up to this being an airshow/display team livery. All in all, I am quite happy with this model, it was a real challenge to make in the limits of the parts I had, so much so was actually running out of 3L pins, but it came together nicely, and the color scheme actually worked out a lot better than I expected it to. Now, on to the contest. Stay safe out there, folks. P.S. I'll give a shout out to the first person who is able to guess where the manufacturer's name of this heli came from.
  19. Hi, all, After lurking around the forum for a bit, I decided it was time to post my first MOC. This is a Star Destroyer, made from the parts in 42028 Bulldozer set. Overview: I started this MOC while experimenting with different frames and connections between parts. After some trial and error, I created a triangular frame with the sides bent in. Having just seen The Last Jedi, I was obsessed with all things Star Wars and decided to attempt an ambitious build for my low skill level- a Star Destroyer. Given that I am not the kind of person who likes to mix their sets together, I eventually settled on the 42028 set to create this MOC from- not only because the low parts count would provide a challenge, but also it would be kind of fun to see a yellow... Banana Destroyer? The frame was primarily constructed of beams and perpendicular connectors: (Note that this construction, while fitting together properly, created some stress on the parts- portions of the front push each other a bit owing to the tightness of the frame. But it's the best solution I could find given the space/ parts available. ) After that was complete, I built the engines and the distinctive cabin and attached them: Features: Authentic body shape Posable turbolasers Built entirely from parts in 42028 Bulldozer set Detailed engines and cabin More Pictures: I hope you enjoyed my MOC! Thank you for stopping by, and I appreciate all feedback, comments, and suggestions! Regards, Magical Duck
  20. Hi guys and gals, first post here, been following the forum for about 3 years now. Got bitten by the Technic bug with 42046 and here I am today. Recently bought a 42106 for cheap in Bulgaria and after building 42070 earlier the sloped panels got me thinking - there is a truck hood in this. Sooooo, let's make a truck C-model out of 42106! Full size pictures are located here:https://imgur.com/a/wOlijkp The aim of the C model is to be able to tow trailers like the MACK Anthem's one. M Longer inspired me by his 42075 terminal truck. We'll see if I manage to implement it somehow. The chassis is the same from 42106's pickup truck, then reversed a bit. Track has been widened by 2 studs, fenders made wider as well. The rear has dual tires which for the contest will be swapped with a single one just as the front axle. Currently they are a placeholder and proportions tool... I've seen how long the rules topic is so I had to put this text here... Initially it began as the chassis above, trying to figure where to stick the cab: Then after I figured out its placement came time to adjust where the doors would be. Which happen to be the ramps from the trailer. After some further shaping of the fenders and color swaps until it felt right - I got this below. The blue pins protrude for now as everything was just in sketch phase. Makes it easier to disassemble... Final shot of this for now is this: Further will come soon. I hope this qualifies for the contest as it is almost 17 studs high, please let me know if I can enter. If I can't - I'll continue working on the C model aspect of it. Cheers from Bulgaria! p.s. I am entering this C model in the https://thelegocarblog.com/2020/04/30/tlcb-lock-down-b-model-competition/ The finishing touches and updates were made in May, so I hope it qualifies.
  21. Yes, another C-model of the 42078 set In the last 3 months I enjoyed my spare time in building a C-model of the 42078 Mack Anthem. My truck is an 8x4 flatbed version, with foldable crane behind the cab. I worked a lot on the cab shape, as already mentioned in @grego18f topic, who was building a Volvo FH too! It has opening doors but no tilting cab and no fake engine (I preferred a better looking cab than changing the shape to let the cab tilt). The crane is functional (all functions are manual), knobs are on both sides of the model. Main problem is the absence of the turntable. The crane is quite stable, but of course cannot load heavy loads. You can of course mod it adding a small turntable Outriggers control knob is on the back: I added 2 attachments: fake hook with chains, to move a small container, and forklift to move small pallets. Video: Model consists of around 1500 parts (so you have around 1000 leftover parts - mostly small parts and Lego System bricks). Instructions can be found on rebrickable: https://rebrickable.com/mocs/MOC-34643/technicprojects/volvo-crane-truck Stickers are custom made and could be available for purchase soon. I hope you like it!
  22. I just found another great model made of 42078 "Mack Anthem" set by @MrTekneex, a well-known C-models maker: The features are: Tilting cabin Openable doors HOG steering with working steering wheel (ahh, another cabover truck with tilting cabin and working steering wheel ) Working 6L engine Rear "doubles" at the driven 2nd axle Front and 3rd axles steering The 3rd axle is also liftable (has no steering in the raised position) Roll-off and landing / loading the container in three steps, each is driven by its own LA (or rack+housing) Dump the container Locable door of the container So far it's only on this website, so hopefully, it might appear at the Rebribale as well...
  23. Hi all, This topic is for discussion of the new C-Model Index (under construction here), and for suggestions of C-Models for inclusion. I hope the index will help us all keep track of the great C-Models people have created, and in many cases, their instructions. I've managed to find a good collection to get started, but no doubt I will have missed some, so please tell me any you'd like to see added (or any mistakes/missing details/etc), and I'll add them in future updates. Rules for inclusion: Uses parts from only one set; That's about it! Where possible, I'll list details of EB topic, youtube video, instructions, and part count. Models detailed on EB are obviously favoured, but I've already come across one or two from elsewhere which I feel deserve to be included. They are listed in no particular order. Where individuals have listed their creations as C-Model, D-Model, etc, I have ignored this and called them all C-Models, because each designer's classification doesn't work when all compiled together. To keep this manageable, I'm going to try and release these in groups according to the original set. To start with, here's all the C-Models I have managed to round up for the set that got me out of my dark age - and perhaps its no surprise, given the sheer number of useful parts: [EDIT: moved 42009 into the index.] Hope this is useful - suggestions welcome.

    [C-model] Yoda's Mech (alternate build 75168)

    I got Yoda's Jedi Starfighter a while ago as a gift from a friend. I normally make c-models of Technic sets, so initially I wasn't sure what to do with this after building the main model (other than a Tulip!). This set has a range of Technic pieces so it was familiar but also a nice change. There no ball joints that are usually associated with Lego mechs but I thought I could still manage a range of motions. I built the frame first using the Technic pieces before adding the decoration. In the end I managed to create knee, hip and shoulder joints and the model is reasonably stable and pose-able. The Mech is equipped with missile launchers, force blasters and can transform into a flying mode, allowing Yoda to soar over rough terrain. It can crouch down for easy access to the cockpit.I quickly settled on the design for the feet and arms which shaped the way the build turned out. The knee and hip joints were revised a couple of times before settling on the current version. The wings are actually an important part of the model to ensure it remains balanced. More details and instructions: https://rebrickable.com/mocs/MOC-29490/thekitchenscientist/yodas-mech/
  25. I'd like to share with a quartet of c-models which are based on A-models from 2018-19. There has been no model since the Racing Yacht and Heavy Duty Forklift that had that special something to make me want to buy it (the Car Transporter came very close). I typically stick to buying the low/mid range sets and now have around 20. I enjoy the challenge of C-model creation as you can see on bricksafe, and using Rebrickable.com I looked at which of the 2018-19 line-up I could enjoy the building experience for using bricks from my existing sets. I initially was going to make the First Responder from the Airport Rescue Vehicle but the similarities with the B-model for this set ruled it out. Turning the Racing Yacht into the Powerboat was a logical next step. I tried to follow the instructions for 42089 making substitutions and skipping sections as required. Once that was done, I went back over the model with the remaining pieces to try and find a way to complete it whilst keeping the vibe of the parent model. This process made me very familiar with the instructions for 42089 such that I tried again with the Heavy Lift Helicopter and Airport Rescue Vehicle. Having woken up my brain to the possibilities, I went back to Rebrickable.com to look for a bigger challenge. Comments in reviews about the chassis for the Rally Racer put me onto the 24 Hours Race Car being a good candidate. This followed the same basic process as before but this time need much bigger reworks. I often realised the piece I really need to complete the bodywork of the model had been used elsewhere in the chassis, and a swap would be needed. I'm pretty pleased with the outcome. This idea of recreating an A-model as a C-model is not new (https://rebrickable.com/users/klimax/mocs/ has a number of examples). More pictures of each model can be found on Bricksafe (https://bricksafe.com/pages/TheKitchenScientist). This version of the Rally Car has kept the suspension and HOG steering but lost the opening front/rear. I managed to add steering via the steering wheel. The brick built 3-cylinder engine is not linked to the wheels but turns with the propeller. Using a worm gear I was able to link the propeller to the wheels but there was no engine this time. This model had all the parts to recreate the engine/wheels/propeller functionality but lacked some of the panels needed to keep it power-boaty. As a compromise I took the arm mechanism from the Airport Rescue Vehicle and mounted in the extended boat.
