    Hey man, love it
    I build it a while ago and it was full of random colors lol, i think I’ll revisit it and make a solid color.

    Hi Agrof,

    This is an amazing MOC.

    I just completed ordering all the parts missing for my build. (bought a secondhand 9398, I have one already and that one and your buggy is going to be two center pieces in my  living room).

    Can't wait to get all the parts and start building :)

    Thanks a lot for sharing the instructions and I will keep you posted.

    Kind Regards,

    Eranda

    Hi Agrof, I was going to build your other buggy (11711, Ultra 4 Crawler) but it uses 2 of the Technic 4 Ball Joint Steering Arm which are around $20 each where I live (Australia) - so then I found this one which also looks really good (and fast!) but I noticed that it uses 2 x Large PF motors instead of 2 x XL motors like the Ultra 4 - so could I possibly still use the XL motors for this model or is it too small to fit both in?  Obviously I'll try anyway - but Just trying to find a fast buggy I can build with 2 x XL motors and without having to buy $20 ball joints!
    One other Q - not sure how many buggies you've built, but which do you think is your best one?  In terms of 1) speed and 2) ruggedness?
    • 1 year, 2 months ago agrof (3K) MOC Designer
      Hi,

      due to the connection points of the L-motor, it was structural part of the swingarms. Sure, there must be a way for XL motors, but this MOC was more a "proof of concept", so speed and torque is not the best, but still acceptable.
      By the way, the Ultra 4 operates with L-motors too - this one can be geared up easily (see picture in the comments), so I think that one is more fun to play with!

      I hope You will still enjoy the build, and don't be afraid to tweak it for your taste! Cheers! :)

      P.S.:
      I also recommend to take a look at on this one from Didumos69 - superb performance for a LEGO car!!

        Thanks agrof - I have all the parts ready for the Ultra 4 except the 4 head ball joints (because of their price) so I will build that and work out how to tweak the steering so it uses normal steering joints.

        Thanks for the link to Didumos's buggy - I've seen that before and it's very impressive but I don't have 4 L motors and at present (because I'm between jobs) I can't really afford 2 x BuWizz.... they are top of my list to buy as soon as I have money coming in again though :-)

    Hi,
    it took a very long time, from saw this MOC to the day start building, but now all parts are here incl the Tires.
    I will start in the next days, after the day temp go down a bit. ;-)
    What I have changed in my Partlist is the BatterieBox, I will use on of GBCPeter (Doctorbrick Forum) LiPo Boxes, that will give that MOC the right Power with the SBrick.
    You will find Pics and Videos then on my Webseite (SteineSucht.de)

      Sounds great, nice website You have! :)
  • 1 year, 5 months ago grzegorz (494)
    well downloaded part list to my bricklink ,checked my spares and already have 53% of needed parts plus going to use Buwizz . thanks for sharing instruction
  • 1 year, 8 months ago Markys (834)
    I saw this model many times in the video. and could not find the author and the instruction. he only accidentally jumped on it. the author is well done. this is a great model. she really is interested in playing. Thanks for the instruction. I wish new such good models!
  • 1 year, 10 months ago agrof (3K) MOC Designer
    A nice patch for the rear swingarms by Didumos. Thanks for it!
    I applied it, worth it totally! Now the inner hinge can not disconnected.
    • 1 year, 10 months ago asiadream (3K)
      could you update it into step instruction?
      • 1 year, 10 months ago agrof (3K) MOC Designer
        The BAD: sorry, not really. Actually with a little analysis, anyone is able to reproduce based on the picture above. To integrate into the original instructions would take a lot of time, and I closed this project already. 
        The GOOD: I am working on new MOCs instead! ;)
  • 1 year, 10 months ago asiadream (3K)
    I don;t see part 32039 in DBG used in anywhere of this instruction. Could you check it again?
    • 1 year, 10 months ago agrof (3K) MOC Designer
      Hi, it is on page 113, used for the dummy shifting lever. Can be any other color or completely ignored, as preferred. Have fun! :)
      • 1 year, 10 months ago asiadream (3K)
        I see but it is LBG in your instruction, anyway. Can you revise this Moc with 2x buggy motor, will be more powerful! Another person adready do it but I still wait from you...
        • 1 year, 10 months ago agrof (3K) MOC Designer
          Hi,

          I will not make buggy motor version of it, because:
          - I don't own any buggy motor, nor power units to feed them.
          - I wanted to build this model based on actual available parts, to make it more affordable to anyone - considering myself as first. :)  I spent quite some time to reduce the parts variety (in colors perspective too)  in order to reach this goal.

          I leave MODding to anyone who loves to build according to own creativity. ;)
          Happy building!
          • 1 year, 10 months ago asiadream (3K)
            Just another "ultimate version with buggy motor" I think.
  • 2 years, 4 months ago aefferen (849) MOC Designer
    Great build. Just build it this weekend. Design fit for a Lego set TMHO. Really enjoyed it. It is apitty these Lego motors have no real speed. With an Sbrick even better. Great Work!
    I made a small adjustment for the top of the rear suspension construction. Too much tension. picture here https://1drv.ms/i/s!AgHsqH4f-2LZrBnj4oNGdSvS-uG2
    • 2 years, 4 months ago agrof (3K) MOC Designer
      Thanks for the honest notice, good solution, I will implement on mine too. :)

    Nice Bodywork :). It looks really realistic!

    excuse my english im from germany
    I build it and it`s sooooo nice and very powerful. great job agrof. Keep it up!
    I will make a YouTube Video from this modell (of course with a link to your side;) )I would
    wrote in the description and video that the MOC isn`t from me. may I could do this :)

      Hi,

      selbstverständlich, einfach los damit! Viel Spaß dazu, und freue mich sehr, daß Dir meiner Buggy auch gefällt. :)

      Please just put the link for your video here, I am very interested to watch.
      Feel free to comment it, even negative critics are welcome, let's see what can be improved. ;)

      Cheers!

        Hi agrof,
        I finished the video yesterday evening. I have a little improvement regarding the toplights of the model. I think they are too small, I used big offroad lights, you can see it in the video. It was very funny and difficult to make this video. I hope you enjoy it :)

          Very cool, I am very glad to see. Thank You for sharing (and for giving credits)!
          I hope You enjoyed the build and the ride, as much I did. :)

          One remark: check the position of the battery box holder (2x 32140; instruction page 253-254), they should be on the inside, so the box can sit on them, and will be more secured during the ride.

    Very nice buggy. Love those things. The instructions are good to follow. Great job.
    • 3 years, 4 months ago agrof (3K) MOC Designer
      Thank You! :)
  • 3 years, 4 months ago SALB (1069)
    Nice buggy! I like the suspension, looks and functionality of this buggy. Also why are you using two IR remotes? I don't have power functions just a Mindstorms NXT 2.0 in which i am trying to build a 1:10 jeep.
    • 3 years, 4 months ago agrof (3K) MOC Designer
      Hi, thank You!

      For the answer, please scroll down here, we discussed with offroadcreations about this. Hope it helps.

    Hi Agrof,
    I would really like to build this, but how did you get the tires?
    Thanks!

  • 3 years, 6 months ago offroadcreations (10K) MOC Designer
    This is really cool! I plan on building this, but since I only have 1 IR Receiver, I will use a Polarity Reverser for one of the motors. Do you think the truck would still be the same speed as the one with 2 Receivers?
    • 3 years, 6 months ago agrof (3K) MOC Designer
      Hello!
      The polarity reverser is needed anyway, due to the construction of the rear axles. One of the motor must rotate in opposite direction.
      It has no influence on the speed with 1 Receiver, but will mess up some things. I don't recommend to do it!
      If You use 1 port for both motors, they will rotate in the same direction, resulting the rear wheels rotate in opposite way, one forward, one backward. This will for sure break something (mechanical, or electrical). To avoid this, it is written in the instructions as well as double check: test in hand first! ;)
      If You use 2 ports for 2 motors separately (as it is showed in the instructions), it will be OK, but You have no port left for the servo for steering.
      I made really lot thoughts about the driveline, and this was the optimal way: to trick out the mechanical constrains with an electrical move (i.e.: polarity reverser).

      Short answer: I recommend to buy another IR Receiver. I hope You will still enjoy the build! :)
      • 3 years, 6 months ago offroadcreations (10K) MOC Designer
        Thank you! When I said polarity reverser, I meant the actual PF Switch, not the one on the remote. I should have been clearer :) I will probably try one with 2 Receivers, and one with just 1 and a PF Switch (and no lights) to see which works best. Thanks again, and I'm sure I will enjoy the build ;)
        • 3 years, 6 months ago agrof (3K) MOC Designer
          Aaaahaaa! :)
          Interesting idea, and probably will work. How will affect the speed... no idea. If You have tested it, feedback is always appretiated here! :)
          • 3 years, 6 months ago offroadcreations (10K) MOC Designer
            After testing many different configurations, I found the best setup to get the most power and speed out of this, and I have to say, the result isn't surprising: If you put one L-Motor on each port of 1 Receiver, and a Servo Motor on one port and the lights on the other port of another Receiver, and attach one Receiver to a battery box, and the other to a 9-volt battery using a Minizip, the buggy goes the fastest. The speed was much faster than using just one battery box. Again, this is an awesome, monstrous buggy, that looks amazing, especially when its being driven. :)
            • 3 years, 6 months ago agrof (3K) MOC Designer
              Thank You for the worthful experiment, and for the compliment!
              I am sure these informations will come handy for many other Mocs. :)
  • 3 years, 6 months ago Chade (2K) MOC Designer
    I built this MOC a few days ago, and you've done a suberb job on it. The placement of the L motors at the back is quite ingenious, and I learnt some interesting techniques on how to angle the panels. The instructions were also excellent. I'm not a big fan of the front bumper as it was bending the axle a bit, and one pin was slightly bent from the front side panel after deconstruction. Overall, it's an outstanding model, I hope to see more of your work in the future :)
  • 3 years, 8 months ago the.geremy (710)
    perfect, nice design and even better drivability
  • 3 years, 8 months ago spadgy (1659)
    @ Agrof I love this MOC, and the clear level of research that went into it! In fact, I work as a journalist, and cover Technic stuff for a UK-based LEGO magazine. Each month I spotlight a Technic MOC, and I'd love to feature yours (all I'd really need is permission to use your photos... but I'd love to chat more on email; maybe get a quote from you on all that research!). And I'm building the MOC myself! If you're interested, drop me a line to will [dot] freeman [at] spadgy [dot] com. Thanks!
  • 3 years, 8 months ago psmyth (6K)
    just finished this MOC and it looks and works great. Nice plans(some photo's are a bit washed out) and well laid out. I tried it with Sbrick and works great!! Thanks....too bad it doesn't go faster!!
  • 3 years, 9 months ago BritishBob (43)
    Great model! I would love to build it but I don't have the L motors at the moment. :( Will build ASAP!

    @ agrof: where did you get the stickers?
