Lego Technic 42129 C model Unimog

Building Instructions available on Rebrickable:
rebrickable.co...
This model is a rebuild of the Lego Technic Mercedes Benz Zetros into a Mercedes Unimog trial truck, with the aim of making a more off-road capable machine. It features a 2-speed gearbox with faster gearing, 4-link floating axle rear suspension with large articulation, softer 3-link floating axle front suspension, openable and lockable doors and bed cover, spinning fan under the hood, all in a compact form factor, with details such as rollbar/bullbar, snorkel, mirrors and fire extinguishers.

wow, this literally solves all the problems of the a-model! I love unimogs...

[@viktorgyenes8368]

Thanks, glad you appreciate it! Unimogs are cool :)

How to say that,... This car us build of ideas! And this means a lot! I have this set as well, and was going to build my own MOC crawler and your build give me so much inspiration! Keep building!

[@viktorgyenes8368]

Thanks, I'm glad I inspired you! Have fun with the set, curious what you come up with!

Driving posture is great ；）

[@viktorgyenes8368]

Thanks :) Do you mean the center of weight?

[@jareddeckard2703]

I love it! Much better than the A model. Your builds just keep getting better and better! I subscribed. Also, how long did it take you to build?

[@viktorgyenes8368]

Thanks a lot, I appreciate it! This one took quite a bit of time, about a month, as I experimented with different suspension/drivetrain concepts before settling on this one. And then some more time spent on the video itself..

[@jareddeckard2703]

Cool! Thank you! I can't wait to see your next build!

[@unclebob8419]

Great MOC. Does this improve the turning circle?

[@viktorgyenes8368]

Thanks! Yes it does! Though it's not perfect because it has locked differentials and it's harder to turn with that..

Классно получилось, по проходимости за счет короткой базы наверняка лучше оригинала.

[@viktorgyenes8368]

Thanks, glad to hear that!

[@markor80]

This is just perfect! Tell me pls, do i need some extra parts to build This Unimog or all parts are taken from model A?

[@viktorgyenes8368]

Thanks! Nothing extra required, just the A model. Enjoy!

[@joelabhishek0074]

I love it but one suggestion bro can you pls add more gears and the diffential in the model cause I have too much extra parts and I don’t want it to go to waste especially those heavy duty differentials

[@viktorgyenes8368]

Thanks! What do you mean add gears, for what function? Did you read the description on Rebrickable (link in the video description) about why it does not have differentials? Also, in the comments on Rebrickable there's some discussion about how they can be added back and what other problems it brings..

[@joelabhishek0074]

@@viktorgyenes8368 I meant add more gears to the gearbox to affect the speed and torque more.also I read on how to add the differential and I did not understand anything.is it ok if you could explain it to more simpler.Also I am a huge fan of the 42099 beasty mic.pls never stop building sweet Mocs

[@viktorgyenes8368]

@@joelabhishek0074 First, it is not possible to increase torque and speed. If you increase speed, you loose torque, if you decrease speed you gain torque. That's how physics works. But that's why it has a gearbox :) Second, there is no room for more gears in the drivetrain.. About the differential, well I cannot tell it more simply with words, but the bottom line is you just have to take out the gearing and put in the diff and replace some axles with shorter ones. But the problem is that it may end up too weak and fall apart under stress, as one axle would be half stud too short in the front.
