LEGO Technic Bugatti Chiron (42083): Another Member Build

Member build

Another one bites the Chiron

This is the third member build post we have on the Bugatti Chiron (42083), and I keep publishing them because the photos keep coming in. It is one of the most-built kits in the library. Alan built one, another member built one, and now here is a third.

The reason members keep requesting the Chiron is the gearbox. It is the best functional gearbox LEGO Technic has ever put in a consumer set. Eight sequential gears, shifted via a paddle-style mechanism, genuinely working as a dual-clutch sequential system. You can feel the gates when you shift. Most people spend at least an hour just working through the gears on the finished model before they put it on a shelf.

The real Chiron runs an 8-litre quad-turbocharged W16 producing around 1,500 bhp, and LEGO matched that with a W16 engine block with moving pistons at 1:8 scale. The two-tone blue and black livery follows the “Sky View” variant. Working front and rear suspension, functional steering, opening roof panels and rear engine cover.

Worth knowing

The 8-speed gearbox is the reason this kit is a library staple. LEGO Technic has never shipped a more complex gearbox in a consumer set. Members routinely spend time on the gearbox alone before even looking at the bodywork.

The useful thing about a second or third member build is that it stops the post feeling like a one-off. Different builders notice different parts of the same kit, and the photos always come out slightly differently.

That is why I keep publishing repeat builds when they come in. If a kit keeps being requested, that tells me something about the library. If members keep sending photos, that tells me even more.

LEGO Technic Dom’s Dodge Charger (42111): Alan’s Build Diary

Alan builds Dom’s Dodge Charger

Alan sent in these build diary photos from when he was working through the 42111. They show the Charger coming together from the sub-assemblies up, which is actually a better way to see what this kit involves than a photo of the finished model. You get to see the V8 engine block before the hood closes over it, and the chassis before the bodywork goes on.

The 42111 was significant when it came out in 2020. LEGO licensing a Hollywood franchise for a Technic set was new territory. The subject is Dominic Toretto’s 1970 Dodge Charger R/T from the Fast and Furious films, and LEGO took it seriously. The proportions are right, the engine bay detail is there, and at 1,077 pieces it sits comfortably in the library as a solid evening project.

The build splits into two main parallel assemblies that come together at around the halfway point. The left-hand sub-assembly is the powertrain: engine block, gearbox, and suspension components. The right-hand one is the chassis frame. When you bolt them together the whole structure becomes rigid and the scale of the model is suddenly obvious. It is a big car.

The engine detail

The V8 engine is the reason to build this kit. Eight pistons move as the model rolls, visible through the opening hood. Red valve covers, grey headers, rubber hose details running across the top of the block. LEGO did not cut corners here. It is the best thing about the 42111 and it is genuinely a good piece of engineering in miniature.

The hood opens on a hinge and stays open, which means the engine sits on display. This is the right call for a kit where the engine is the main mechanical feature. The Charger’s bonnet is already distinctive in the real car, and the LEGO version captures the flat, long shape of it reasonably well.

Steering is functional via the front wheels, and the suspension at both ends compresses and rebounds with a bit of weight on the chassis. Nothing unusual for this level of Technic, but it feels right given the source material. The film version of this car takes a beating and it is appropriate that the model has some give in it.

If you are a Brick Club member and you have been photographing your build, track your build progress and upload your photos in your members build account. Alan’s build diary photos are a great example of what we like to see.

More in the fleet

Alan build diaries are useful because they slow the kit down. A finished Charger photo tells you the shape worked. The progress shots show where the time went: the V8, the rear axle, the frame, then the black bodywork closing around it.

That is exactly the sort of member content I want more of. It helps other builders decide whether a kit is their kind of evening, and it shows the library being used by someone who actually cares about the build rather than just the box.

LEGO Technic 4×4 X-treme Off-Roader (42099): Alan’s Build

Alan takes on the 4×4 X-treme Off-Roader

Alan has been working steadily through the library and the 42099 landed with him earlier in the year. It is the set people ask about most when they see the fleet. The four individual track modules catch the eye immediately, and the fact it is app-controlled puts it in a different category to most of what we carry.

This was one of the first sets LEGO released under the Control+ banner back in 2019. Two XL motors sit in the chassis, a battery box tucks into the body, and the whole thing connects to the LEGO TECHNIC Control+ app over Bluetooth. You get steering, variable speed, and a tilting body function. The front arm raises and lowers. Alan’s photos show it coming together over a few sessions.

Highlight4 independent tracked modules

The four track modules are what makes this build worthwhile. Each one is independent of the others, with its own mounting point and its own small degree of flex in the chassis. When you lay the main frame on the table and start attaching them one at a time, you understand why the piece count is 958. A good chunk of that is the tracks themselves. Each rubber chain is around 40 links long. Assembly takes longer than you expect.

The build sequence is logical enough, but the Control+ integration means you are fitting electronic components through the process rather than at the end. The battery box goes in early and you have to route the motor cables as you build the body around them. It is not difficult but it requires a bit of patience to keep things tidy inside.

What the app actually adds

The Control+ app is not just a gimmick on this one. Proportional steering through the touch controls feels more satisfying than a physical knob on a smaller set, and the body tilt function looks good in motion. If there are children around, this holds their attention considerably longer than a manually operated model.

I think the 42099 is one of the better arguments for app control in the Technic range. Some sets where the app is the main selling point end up feeling like the build was an afterthought. This one is not that. The chassis is solid, the track modules are well engineered, and the app control adds something rather than replacing something.

More in the fleet

Alan has a good eye for the mechanical bit of a Technic build, and the 42099 gives you plenty to look at before the body is finished. The app-control side gets the attention, but the real interest is how the drive modules and suspension make the finished model feel like a crawler rather than a display truck.

I like seeing this one in member photos because it is not neat in the usual supercar way. It is squat, odd, and built to move. That is a useful change of pace in a library that has a lot of polished cars.

LEGO Technic 42028 Bulldozer: Inside One of Our Ambassador Builds

Piece Count617
Released2014
Build Time2-3 hrs
Models2-in-1
DifficultyMedium

Thelegopod has been a regular in the Brick Club Facebook group for a while now. He built the LEGO Technic 42028 Bulldozer, put together a collage of the build, and sent it over. The video is below. Before you watch, here’s some context on what the 42028 actually is and why it’s a good use of build time.

The Set

LEGO Technic 42028 Bulldozer

Set 42028 is the LEGO Technic Bulldozer from 2014. 617 pieces, rubber caterpillar tracks, yellow and black. It builds into an 11-inch long bulldozer with a working front blade and rear ripper, plus a four-cylinder engine under the hood with pistons that move as you push the model.

It’s a 2-in-1: the same parts rebuild into a Trench Digger if you want the alternate model after the main build.

What the build is like

Accessible, mechanical, genuinely satisfying

At 617 pieces this is something you can get through in two to three hours without it feeling like a slog. The most involved section is the track assembly: rubber link-chain treads are always fiddly to tension, and the 42028 is no exception. Once it’s done the model moves realistically.

The tracks and blade are what you’ll actually play with. The rear ripper moves independently but it’s more of a passive feature than an active one.

Build highlight

The front blade mechanism is cleverly done. Rather than a gear on top of the model, it works through the exhaust pipe. One push raises and lowers the blade. It keeps the top of the model clean, and it’s the kind of detail you notice once the kit’s been on the shelf a few days.

I love seeing these older Technic builds still getting proper attention. They are not always the biggest sets in the library, but they often have the clearest functions, and that is a big part of why Technic works.

If you have a build collage, a short video, or a few photos from your latest kit, send them over. I would rather the blog showed real member builds than polished catalogue angles.
