Another Brick in the World

Hi guys! As some of you may know, I'm a huge off-road fan. I never really saw the potential in on-road, and sometimes found it boring. But then, I watched a few drifting videos and instantly saw the potential to make a LEGO drifter. I got in touch with my friend @N1K0L4, which is an on-road fan and has experience in the field, and sent me a couple of chassis designs. I obviously chose the most overpowered one You can check out N1K0L4's chassis here, and the full rebrickable post here. Now, let's go with the details: Features RWD with 2 BuWizz Motors Steering with a C+ L motor Realistic looking bodywork resembling Ken Block's Hoonitruck All fueled-in with a BuWizz 3.0 unit For me, one of the most important functions is the drivetrain. It's built in a very clever way with the 2 BuWizz motors leaving just enough space for housing the BuWizz 3.0 unit. It's RWD, which isn't true to the real-life counterpart, but N1K0L4 is working on a new version with AWD and it's looking very promising! updates about the AWD version will be made in this topic. To finish it off, the steering was added, using a rack and pinion setup to have as little slack as possible as that's a key factor in mini-racers. It's steered with a C+ L motor as said earlier, with this being my first time using C+ electronics. I have mixed feelings about it, but more on that later. The bodywork was an interesting one. I wanted it to be as accurate as possible to the real deal, but I had to use white mudguards as LEGO for some reason doesn't produce them in black. Still, they didn't spoil too much the body for it to be recognizable, so I'm happy with it. Still, it was somewhat flimsy and would tear to pieces if I hit a jump wrong. Still, N1K0L4 has also addressed this while still making it more accurate. I guess union makes strength For the video, I wanted to use a different setting in comparison to my other videos, as it's a very different model to the previous ones. I chose to go to a skate park, as it had some smooth concrete sections for drifting, and ramps to do some jumps, which is exactly what this model was built for. The model handled excellently in spite it's RWD, although I'm not used to models this fast, so I hit jumps wrong dozens of times. There are some included in the video, but many weren't included, but I'm considering making a bloopers video. How would you guys feel about that? However, the parts didn't like the skate park, as concrete is very abrasive to abs plastic. The splitter was melted and torn to pieces, and the tires lost most of their thread in the process, up to the point where I had to use to sets of them to record the video. I guess I'm a bit of an aggressive driver, but you should be aware of that if you build this model. About the C+ electronics, I'm not fully sold out. They do have some pros, like the more convenient shape of the motors or the faster response, but they show some disadvantages when taken into closer inspection. The steering trim was a pain to get right, and even when that was the case, it still veered ever so slightly to one side. I think it has to do with the fact that the 0 position is digital and not physical. Still, I'm considering using them in future build mostly because of the easier integration, but will probably stick to PF servos for faster models as they return to center more accurately. Feel free to post a comment about what your thoughts are about it, and see you in the next one!

For me it would have to be 42110 Land Rover defender. This may be considered as a somewhat controversial pick, but I chose it because it was for me one of the last "true" technic sets, with a gearbox, 4x4 drive, suspension and steering. Not to mention it was one of the sets that brought me from my dark ages, a couple of years ago. Still, I also like some older ones, like the 8860, as it was pretty much the first supercar (besides 853), and also the first one with a differential. Overall a very nice set in spite the somewhat crude looks.

Thank you! Yeah, freewheeling does create some friction, but with some lubricant it should be OK. Still, I tested it before lubricating it downhill, and at some point it would reach some speed where it would be somewhat hard to stop it. Thank you for your praise! It actually uses 2 BuWizz motors inside, but it's still quite impressive :) About solid axles, I consider that type of suspension to be great for smaller models like my Jeep or your very nice Geo Tracker. They're realistic, but they don't work as well for fast off-road models. They have a high complexity (Many links that can pop off, stress on driveshafts, torque twist...) and they have a high unsprung mass as they suspend the entire axle which leads to a worse responsibility. That's the reason why I didn't use them in this MOC. Overall, I really encourage you to build something like this

Very nice model! it seems to perform very well even at full throttle. The axles look very interesting too, and very sturdy. Would a 3D file or building instructions be possible?

Nice model! When I saw the YouTube video, I was very interested in that 2-speed gearbox and decided to make a Mod of it at my usual Claas Xerion tire size. Hope you like it!

Hello again, Back in March 2023 I started my YouTube channel with my Raid Buggy. Granted, it look somewhat crude and it was quite slow, but it was my first model with BuWizz motors and bricks so it has a special place my heart. Recently it was the 1 year anniversary of it, and I decided to make a remake of it to prove some how much my LEGO building skills have changed and to honor the original model and channel. So enough with the backstory, let's get to the details: Features 4 Wheel drive with a 2-speed gearbox steering with double steering racks Soft double-wishbone suspension Working gear stick Bodywork built to resemble the original model One of the things that I wanted to show with this model was that you don't necessarily need 4+ BuWizz motors in order to make a good fast off-roader. For this, I decided to make use of a 2-speed gearbox, which has a low gear with the same gearing as the Raid Buggy V1 and the high gear which is some 67% faster (6.2 km/h). The gearbox design was heavily based off @Zerobricks's excellent Simple Off Roader but modified to fit my needs. Another benefit of this is that it has a neutral gear, which is very useful for downhills. From then, I finished it off with the axles of my Monstermog and the chassis was done! from there, I had to build the bodywork, the part that I had been dreading the most For me the body was a very important part, as I wanted to make it reminiscent of the original yet it would have a more sporty look and a stronger construction. Just like the first model, it uses many connectors in @Attika's characteristic style. In the end, the bodywork suffered many changes but I consider them for the better, as it now has a more imposing look and a much more sturdy connection so it can be rolled over without having to fear of breaking it. And now a few more images: The model ended-up being a very good off-roader, with a somewhat high speed (6.2 km/h) yet with some torque left for harder off-road. I pretty much had no issues with it, except the front open differential which sometimes got in the way when off-roading in the low gear. It's otherwise a model more focused on high-speed on uneven terrain so I'm happy with it If you would like to build this model, you can download the .io file at rebrickable here. And as always, here's a YouTube video containing some off-road footage, functions showcase, and some nice Punk Rock music Feel free to post a comment about what are your thoughts about it, and see you in the next one!

Yes, I will make actually a full topic about the model with gearbox soon. I'll let you know about it when I do so :) (Sorry for the late response)

Yes, it is Well, for me speed isn't as important as overall performance. If that means having to sacrifice speed, I'm willing to do it. Still, it doesn't make much sense to me that a 6 BuWizz motor 6x6 would be slower than a 4 BuWizz motor 4x4 And talk about gearbox, I currently have a model built with a 2 Speed gearbox and 2 BuWizz motors. I'm just waiting to be able to record it.

Thank you for leaving a comment! When I got my hands on the Audi set, I tried doing so, but the axles are designed around 5x7 frames which don't allow space for the larger diameter of the Audi joints. I'll try to redesign the axles in a future build, maybe a 6x6.

Thank you for the support! They hold up ok-ish, but I'd definitely wouldn't recommend using them without any lubricant. These can snap off very easily, and I blew out one of them which no longer stays together when I put power on it. it's one of the weak aspects of this model. If you ever blow up one of these, I'd recommend watching this video.

Hello guys, I would like to present my first Moc here, which was built around November 2023. I recently returned back to Lego for about 2 years now. I have built a few Mocs, but I have not found them good enough to show to others. After having built my trophy truck prerunner, I wanted to build another 4x4 with 4 BuWizz motors at a smaller scale. Then, my friend @N1K0L4 sent me an prototype chassis, which I later on finished. You can find a finished version of this chassis in the form of a 4WD buggy here. The model features the following features: 4 Wheel drive (4 BuWizz Motors) Front Wheel Steering with Ackermann geometry (Power Functions Servo) Skid Steering Removable body All fueled in with 2 BuWizz 2.0 units One of the biggest highlights of this model is its drive train. The horizontally placed BuWizz motors allow for a very compact chassis, with the added benefit of independent wheel drive and low center of gravity. This is what really convinced me to build @N1K0L4's chassis. And no off-roader is complete without suspension, which this model has. It features an independent suspension design, with double shock absorbers per wheel. I would have liked to add actual pneumatic shock absorbers, but I don't have any pneumatic cylinders. Still, if any of you builds it, you can try adding them and seeing the effect. A couple of more images: The model performed very well off-road, having a high speed while still leaving some torque for crawling. This is actually one of my best performing models (only after the Monstermog, that is just a beast ). I think the only drawback this model has is the usage of the old type of CV joints, which can deform on high torque. I actually blew out one while testing a WIP. I guess the perfect design doesn't exist Actually, if you want to build this model yourself, I've uploaded the 3D studio file for free on Rebrickable here. And as usual, here's a YouTube video showcasing its off-road capability and features. Feel free to post a comment about what your thoughts about it.
