The entries in this contest were amazing. Congrats to all winners and participants!

That'll be almost 2 years down the line unfortunately. The prices are just terrible.

This is still extremely expensive. Prices have been getting much worse in Canada, and the $100 gap between this and the Chiron for just 100 pieces is atrocious.

This looks amazing in the official pictures, forget anything I said before! I may just have to buy it :)

I spend a lot of time coding (going to uni for computer science) so I may be able to help out here. I don't know anything about the code involved with this psecific project but I can learn. Are there any resources/code bases for any of these controllers out there?

I've made an interior MOD for the car- I've added better seats anda full dashboard. I'm making these MODs such that the least amount of breaking/rebuilding is needed, this one should take about 10 minutes to apply but makes a big difference. Instructions are in the video! https://rebrickable.com/mocs/MOC-43153/BrickbyBrickTechnic/42111-interior-mod-add-a-dashboard-and-better-seats/#comments

They really don't have to look like bricks. But amazing MOCs have been made without massive new panels and molds. This model looks too smooth, that's my only issue. I wasn't even into Lego at that time. I think this is too far, as I told efferman.

Can I be honest? If that's what the real model is gonna look like, then I think it looks super ugly. The color, combined with the unnecessarily smooth panels all around just give it a feeling like it's not even technic. Based on that picture, it looks like a 3rd party brand made it. It better be functional, because that's the only thing that can save it IMO.

@kbalage made a great stance mod, though had to sacrifice the fornt suspension. I wanted to give this a go myself and try to keep the front suspension, here's what I came up with:

Hey guys! I've made my own working steering wheel addition to the set. It's meant to be very simple, and takes only 5 minutes to add! Here are the video instructions: You can find a parts list in the video or on rebrickable: https://rebrickable.com/mocs/MOC-42313/BrickbyBrickTechnic/lego-42111-working-steering-wheel-mod/#comments Thanks and happy modding!

My first video after a long time and my first ever review! Here are my thoughts on the 42111 Dom's Dodge Charger. Let me know if you have any comments or criticism for my review. This is my first time doing this, after all, and it probably isn't great, but it's the best I could do given my limited knowledge of good review-making. Thank you! As well, I plan on making a MODs and improvements video for this set. I plan to include: A working steering wheel Improved suspension Better interior Better access to the wheelie bar A floor for the trunk Some general cosmetic fixes Let me know if there's anything else you want to see! Thanks for reading/watching! BbBT

This looks amazing so far! I can't wait to see how this turns out.

The Tatra looks amazing! I love the blend of system and technic parts and how well they are used together.

This is amazing! So accurate for the scale. One of my favorites so far!

There are some really cool MODs in here! I'll be sure to apply them to my copy of the set. Thanks guys!

Hey everyone, I'm coming out of a sort of "dark age" and wanted to enter TC18 as my first new project, however, after completing the chassis, I realised that I 1) suck at making bodyworks and 2) I didn't have the right pieces to do it anyways. The model was going to be a classic american pickup, but in the end I decided to scrap it. I did make what I believe is a cool chassis, which several functions, and that's what I want to showcase today. It has suspension, a drivetrain with a 2 speed gearbox, and most interestingly, virtual pivot steering. The steering mechanism is compact and not very tall, which let me put the v4 engine on top without the car being so tall either. The whole chassis is also extremely sturdy, despite the complex mechanism within it. Finally this set up is super compact and should be useful in many other MOCs. Anyways, I've gone back to building lego recently and I have a lot of MOCs on the way. I also got a copy of 42111, so expect a lot of C models! Thanks for reading! BbBT

@Jim are pickups or vans allowed?

Is a racing truck an acceptable entry, provided it fits within the size constraints? Or is that too far out of the realm of this contest?

Your boom seems really flimsy, those beams will bend at any opportunity they get. Try reinforcing the sections maybe? More connection points could give you more options to reduce friction.

I'm very sorry to hear this. He made some truly amazing models. My condolences.

Hey everyone, I'm really really excited to share this one with you. It's a Lego Technic swerve drive! This is the first time I've truly combined both software and Lego. The swerve drive sports 2 EV3s equipped with EV3Python V2, along with 8 motors. 1 EV3 controls steering and the other controls driving. Both are sent instructions from my computer (or yours because the code is public) which runs a custom python SSH. The swerve drive can be controlled by a joystick (which is written in with the SSH) or it can run autonomously and detect objects (the 2 EV3s communicate through my computer (another SSH) and send each other instructions). The swerve drive is built with 4 identical modules connected together. It is super robust and runs at a 1:1 gear ratio, but there are 2 places (for each module) where the gear ratio can be changed. If there's one drawback, I'd have to say it's that this thing eats battery like crazy. Each EV3 has 6 batteries, and since they each power 4 motors, battery drops very quickly to unusable rates. This is most likely caused by the weight of the model but other optimisations could be made too. OK, I'll stop talking. There's a document with further explanation here. Here's the video! (The code is in the description of the video) Pictures: That's all from me. This project was a blast, so expect more (like lots more) EV3 soon. Thanks for reading! C&C welcome.

This really cool! One question though: the wheels will undoubtedly need to move outward and then inwards again when you're changing the ride height. How do you plan on overcoming the friction that 8 tractor tires induce?

For me I'd argue that it's a bit of both. Overall they just don't fit the look of the model. There's the seams of the parts all around which look like real Lego... and there's the wheel arch which is complete and occupies the huge region of the model. It just doesn't fit the style so it sticks out in an ugly way.

Agreed. While I love the overall look, those wheel arches do detract from the model.

I think this one was designed by Milan... it looks pretty great!!
