    It would be cool if you could make something simular to this but a little bit faster and more ”Axial Wraith” like. So a bit more lightweight and a bit more faster, or just use RC buggy motors.

    Hi, I want to make this set till I saw the XL gear rack. Do I need the gear rack or can I use the small gear rack? If I need the gear rack what set is it in? Thanks.


  3. NXT45 says:

    Hi, I was looking at this and I wanted to build it but I had 1 question do you need that gear rack or can you substitute? if so what set is in?

    I assume but with hard modifications ! Regards.

    i have a servo and a l moter from 9398
    can i it build?

    @LT64 So why is it necessary to use cv joints? Couldn’t I just replace them with 3L u-joints, or would that cause problems? Plus, I already broke a few of them with high torque, and I can’t get more, because I’m a kid, and I’m not allowed to order stuff online.

  7. LT64 says:

    @josh Buy the pieces on BrickLink 🙂

    Do you ever think you will use a differential?


  9. LT64 says:

    Merci Beaucoup c’est résolu ^^ Mais maintenant même avec les piles chargés a fond le crawler ne grimpe rien … Il se bloque au moindre obstacle, a la moindre montée…

    I have a quick question: Is it really necessary to have CV joints on the steering shaft? I really want to build this crawler, and I just got 9398, but that doesn’t have any CV joints.

  11. Nico71 says:

    Il te faut juste inverser la position de la roue dentée de 20 dents sur l’essieu arrière ou avant. Regarde bien la notice, tu as du te tromper. Si elle est à gauche, passe là à droite, et inversement 🙂

    Hi Nico71 ! I’m not very good in english, so i will expose you my problem in french :

    J’ai construit ton MOC qui a été un plaisir a “builder”, mais en le testant, j’ai remarquer que les deux essieux ne tournent pas dans le même sens… Je ne vois pas d’où cela vient, tu as une idée ?

    Thanks so much if you reply 🙂

    We Built your crawler, but we might have done something wrong in the building, because the CV joints kept falling apart and when we replaced them with 4L universal joints, the axles keep falling out from the 12 tooth gear or the motor. We also have problems with the gearbox and the axle on the back side of the gearbox jumps out and locks the battery box when it rolls over. Do you know how we could fix it.

    Hey, I’m a big fan of your creations and how you are able to integrate such working components. This crawler is no exception to the complex mechanics. I like how you applied the new technic bricks into your model, props! I hope you make more trial trucks soon! I will be looking forward to seeing what else you come up with. Cheers…

    Hey, where do you the wheels or did you color them ?
    And what are the pices in the instructions without a picture ? Answer please!!

  16. Devan says:

    Thanks for the instructions I made a copy and worked great, I had to make my axels using the portals from 8110 as I did not have enough parts for your design.

    Why no Differentials?

    must have a lot of tyre squeal on the kitchen floor – off road its ok I guess…

    Hi Nico,
    This is a very interesting crawler that you did here.
    I am new to lego, just bought myself a 8110 Unimog last month.

    I am really interested in building this crawler. Can you give me a rough estimation how much will all of the parts cost if I were to purchase them from Bricklink?

    Thank you.

    Excellent crawler. I really like your work.

    I performed a cool upgrade you can see the design files here:

    Where you get the Parts?

  21. didier says:

    Tout simplement bravo et merci pour la notice ;


  22. Hugo says:

    Bonjour, voulais vous demander si il ya encore beaucoup pour les déclarations faites?
    Et aussi voulu savoir si la plupart des pièces viennent avec conjuto 8110?

  23. Nico71 says:

    I don’t think so. If you have not the special part, you can build the unimog V4 but without the massive ball-join, I don’t think it is possible to rebuilt one with classic parts. Regards

  24. Nico71 says:

    Soon I hope, In the week or next week.

  25. Mehley says:

    Hi Nico,

    You did a great job again! Excellent modell, well done! 🙂
    I have a question: Do you think is it possible to build it without the special unimog parts? Thank you.

    Kind regards,

  26. Owen says:

    When do you think the instructions will be published? im dieing to build this! 🙂
