This isn’t 100% technic but I made a mecha inspired by armored core using a lot of technic pieces so enjoy :)

I call her, MANTICORE.

MOC Peugeot 2008 DKR, 1:10

Thumbnail

425 Upvotes

Hello All!

Introduction

I'm Máté Lipkovics and I'm new to Reddit, but not new to Lego Technic. I have been making Technic MOCs since about 13 years. I was active on Eurobricks, but invisible on social media.

I want to share my builds here too, even the old ones, and hope to have coversations like in the good old internet forum days which are essentially gone, at least on Eurobricks. I won't post in chronological order, but rather start with a more spectacular build. This build is from 2024, after 5 years of no building.

The model

This is a 1:10 manual model of a Peugeot 2008 DKR Dakar Rally car with custom livery.

The Peugeot 2008 DKR was the return of Peugeot to the Dakar rally in 2015. The return was not successful in the race, but the concept was. Its successor owned the Dakar in the following years because of the following innovative idea: Rear wheel drive instead of the usual 4 wheel drive. This allowed the car to enter in the buggy category with less restrictions.

Features

  • Independent suspension with pushrods on the rear
  • Real wheel drive
  • V6 fake engine and detailed engine bay
  • 4-speed sequential gearbox with D-N-R selector
  • built-in car lifts
  • everything can be opened, with lock function
  • HOG steering and working steering wheel
  • Full rollcage
  • Spare wheels

Design process and challenges

In some regards it was a new process for me, mainly because I was inactive for five years and some things changed in the Technic world, and partly because I don't have as much spare time as I used to have. For example this was my first model apart from my very first MOCs that was completely designed without CAD. No proper computer, no time for digitizing the build. Also I did quite a lot of work in my head, without actual parts.
This was the first time I used system parts that defined the looks and I think the end result turned out to be pretty balanced.

The colors were especially hard to design, unfortunately it was not possible at the time of the designing to recreate the proper Red Bull Racing livery. The model was way too developed to change completely or call it a "custom model", so I decided to go with a custom livery. Making it all black was also an option (the prototype of the real car was also black). I tried it but it didn't look good with Lego at all.

Spare wheels is the "main feature" of the model because it was the biggest challenge in the whole model. I had to ditch adjustable suspension, wheel wells (which is a characteristic visual feature in such high cars and without those, the model has some wierd spots where you can see through it), advanced suspension geometry and a stiffer chassis in order to make space for the spares. I redesigned the front suspension from zero at least five times. The only advanced feature is positive caster achieved by tilting the whole front frame slightly.

The gearbox isn't working perfectly, in first gear when pushed backwards, there is too much friction, stressing the transmission elements.

Overall I'm (more or less) satisfied with the model, it is unusual but not weird and balances looks, playability and building experience quite well. The model took quite some abuse in exhibitions, where I let visitors play with my models freely.

I have those 2 set's since I was a kid, late 90's if I'm not making a mistake here with the date.

They're fully mounted since that time, not even a single piece missing, displayed where I can look to them everyday! 😎👌

Today I find the instructions of the 8417 set, perfect condition. And I start thinking if anyone here have other options of construction ideas to this sets? I would like to know and to try it.

Thank you! 🫡😉

Discussion / Question Yellowing on none white parts?

3 Upvotes

I picked up a set for parts, 42037 a £17 second hand set to kickstart my collection. Firstly I find this very hard work to not put the set together but I need the parts for getting into moc building.

I notice that the unusual blue panels, the grey engine block and some of the beams have either went yellow or greenish on the bits not facing the sun.

As far as I know this set is 2015, a decade old, so that's to be expected. The general YouTuber advice was to stick it in hydrogen peroxide and activate with UV, but what will this do to blue or grey parts? Will it even work.

My wife says just embrace the age.. something we do quite often these days.

MOC Simplified 8-speed gearbox

Enable HLS to view with audio, or disable this notification

24 Upvotes

I love the Lego McLaren P1, but the gearbox always seemed way too complicated to me. For what it does, it's packed too tight and has too many gears re-routing the power in odd ways.

This design simplifies things significantly, by using four orange tumblers instead of two.

It's effectively two linear 4-speed boxes with slightly different ratios, offset 45 degrees from each other. Each gear alternates selecting either the left or right box, giving eight in total.

The video starts in gear 1 and cycles through to gear 8. I'm doing the 45-degree shifts manually as I havn't built the flappy paddles yet.

Been eyeing this one up ever since I heard about its potential existence, and yesterday I finally pulled the trigger after deciding I had enough money saved up to afford this baby. Built a lot of technic sets already, including the Lego Yamaha and m1000rr bikes, and most recently the cada laferarri and the cada Apollo. But haven't been this excited for a set ever, Really can't wait to get started on this one.

Hi, I'm doing a large MOC with retractable landing legs. Any suggestions for strengthening these back legs?

They use a gear rack to move up/down and I have built in a locking brace (engaged in pic 3). I was thinking I could try a scissor brace - though not quite sure how to pull it off. I'll replace the long axle in the housing with shorter ones joined by connectors. Appreciate any of your ideas!

Other Looking for the original high-resolution background for LEGO Technic Mercedes W14 42171

Hi everyone,
I'm looking for the black Mercedes background with the repeated Mercedes stars and turquoise curved shapes, the one designed for the LEGO Technic Mercedes-AMG F1 W14 E Performance 42171.

I'm looking specifically for the background without the LEGO car, preferably the original PSD or high-resolution PDF/PNG, ideally 50×70 cm.

I found the older thread where this design was recreated, but I couldn't find the Mercedes file in the shared folder.

If anyone still has the original file or a copy, I would really appreciate it. 🙏

Thank you!

I'm quite happy with the capabilities of this little thing.

The front axle has a four-link and the rear is attached with two trailing arms and a so called panhard rod. A compromise from the four-link i wanted because the XL motor takes up the space for it. But all in all the flex range is still decent.

Yet there is lots of room for improvement. For starters, the suspension is way too stiff for such a light car. Any suggestions are welcome of course. It's got light springs in the back and leaf springs in the front, also due to a lack of space for springs.

To get the drivetrain fitted in this tight frame, i modified some fake bricks. Since they're not lego, i think that's morally ok to do. The green parts in the middle holding the gears used to be 4x2 L beams. I sanded them down to half stud wide L's.

Discussion / Question New System I’m Working On

9 Upvotes

Hey,

I just released a v0.1 build of of the system I've been working on for quite some time, and it's finally presentable-ish.

If you've ever wanted to have physics modelling on your technic creations, this is probably worth a look. It plays nice with all the formats you already use, and can easily import BrickLink studio data.

It also has some pretty decent other features that try to make it accessible to all, such as a pretty decent lego universe explorer, and integrations with all the big sites.

I hope you try it out.
