    Driving is a bit jerky to start up (a train remote or phone controller would probably help here). The 6th and 7th wheel pair are driven, propulsion is done with 1 XL-motor with a 20:28 reduction (basically no reduction until you come to the differential). Even with the added weight of the carrier and the boom it still is capable of driving around.

    Hi, Probably not the wisest move with three other projects ongoing, but a couple of weeks ago I couldn't resist starting again on designing the Liebherr LTM11200 crane: Some of you may remember the first version of this, which I designed a couple of years ago: This time however I try to iron out all the kinks that were present in the earlier version. It is still work in progress and even though the performance has improved over the earlier version I am still far from a smooth operating, well working machine. Especially the retracting of the outriggers and the whole steering system are still pretty poor performance wise. As you can see I have changed the colour scheme to a more available white with orange livery. Comments, questions and advice are welcome Leg godt Jeroen

    Nice one, loaded with functions. What kind of controller do you use? The M-motor for the rotation of the bucket seems to rotate quite slowly.

    Here is an update of the bodywork. I have lowered the attachment points of the front wheelarches. It looks like a 19L flexaxle will work. I also changed the attachment points so that the frontwheels have more room to steer. It has a lot of floating panels, so it can't be real life tested. I am personally not too sure about the rear paneling in terms of overall styling. It may be too McLaren-ish/Audi compared to the front... What do you think? The LXF file can be found here. Things to do: - Fixate front panels - Fixate rear panels - Finish rest of bodywork Leg godt Jeroen

    Like I wrote, I am waiting for the gearbox, before I want to move on (and doors would also help ;)

    Unbelievable. Especially those shots with the lights on are absolutely amazing!

    Amazing model Definitely worth the wait! Very interesting gearbox, adjustable suspension, sleek bodywork without looking too cluttered. The roofline is still looking a little off, but that is really details in an otherwise brilliant car. It will be interesting to see how this compares to the LEGO version. Are you planning on getting that one to see them side by side?

    First thought when I saw the car was: that looks like a Lambo... So well done on that A few nitpicks (all just my opinion) The wheels stick out a bit too much. Which necesates the (too) wide arch around the front wheels. The rear diffusor feels tucked on The grey 5x7 frame that is visible on the side But that is compensated with super sleek lines in the bodywork, the rear spoiler and the overall Lambo vibe you got into this model

    Oouch, that must have hurt. It is an extremely durable structure indeed, that must have been your saving grace. I hope the mounting of the arm goes with less gravitional hickups.

    I have the same doubt, hence the question to the builders. I also am curious how the angles work IRL. It is always difficult to judge when you have only the CAD file to look at. Let's see how the flexaxles run and then decide on possible changes in the fenders (or maybe the flexaxles need to move outward a bit to cover the wheels better )

    Cute & dense

    Hi, Here is a first attempt for the front bodywork: The holes below the front of the big panels are for the headlights. The lxf can be found here. Questions for the builders: - Is there enough room for the steering and suspension? - Which flex axle length is needed to make a nice curve over the wheels? Question for the frame makers: - The whole of the front body work is connected to one floating 5L axle. A proper mount for that axle would be great. - A Lamborghini has typically a shorter wheelbase (I purposely made the hood quite short so that the window styles can start almost on top of the wheels). Would a shorter wheelbase fit with the gearbox? To do: - Add headlights - Fixate the fenders at the front - Add some paneling at the back of the front tires - The rest of the bodywork I'll wait for the doors & gearbox before I start working on the rear bodywork Leg godt

    Great little model. I like the intricate arm mechanism and the fact that you managed to put that many functions in such a small body. My only criticism would be that the closed bodywork clashes a bit with the skeleton arm. It feels like two designers have been working on this model, loosing a bit of coherence in the process. But other than that, well done
  14. Jeroen Ottens
    And getting close to the mounting the arm on the carrier... Good progress and witty as always
  15. Jeroen Ottens
    It looks really good, but what is with the wormgear in the back? That will loosen itself when you turn the wrong direction I would think... It needs bracing at both ends.
  16. Jeroen Ottens
    I don't mean to design an exact copy of an existing Lambo, but a Lambo-like supercar will need a low hood between the front wheels, so if it is possible to lower the suspension with 2-3 studs between the wheels that would enable this kind of car. If not I would think Audi RS like shapes.

    Sorry, I didn't have time yesterday to work on this project. I'll see if I can spend time on it this week, if not I'd suggest that someone else picks up the bodywork. A Lamborghini would be cool, but than the front axle should be much lower between the wheels. BTW: It might be a good idea to update the first post with the latest LXF file that we are working on. It is a bit difficult to find it by scrolling back through the posts.
  18. Jeroen Ottens
    Me too. Any preference for the colour of the bodywork?
  19. Jeroen Ottens
    The rear axle suspension looks to have a huge travel with the way the springs are mounted. Is it possible to move the lower attachment points closer to the wheel (and the upper attachment points lower?)
  20. Jeroen Ottens
    I agree as well
  21. Jeroen Ottens
    A slight lean forward would be great though. It gives the car an agressive stance. So a slightly higher rear suspension is better than to have equal heights IMHO
  22. Jeroen Ottens
    I meant to react earlier to this awesome project, but things got in the way. That outrigger system is looking great (also from a mechanical/force guidance point of view). The weakest links could well be the mini-LA's you use, they can only handle so much force... Erik Leppen's solution with the small gearrack and the new wormgear would solve that (if that became a problem), but I don't know whether it would fit. I'm looking forward to the next updates.

    Interesting project, I'll definitely be following this. One word of warning though, these wheels in combination with a modular setup will be very tough to implement. At this scale a single stud is already a lot. I am tempted to chime in for the bodywork, but I am afraid I won't be able to put enough time into this, my backlog is growing faster than I can build at this moment. OTOH if you keep the scale like this the bodywork has less area as well, so that shouldn't take too long. So let's see how this evolves, it will take some time before bodywork can start anyway.

    I am abit late to the party, but I have been following this with interest. I was wondering (too late I guess) whether vertically positioned 3x11 panels would be useful for the chassis instead of studded beams. They add also an incredible stiffness when used like that (and when properly braced). Of course you do block a lot of sideway holes and you are quite limited in terms of lengths, since you can only do multiples of 11 studs. Anyway, the build looks great. I like the colourscheme a lot and the combination of pneumatics and electric drive are used in a good way here.

    Great model, it looks very polished and it seems to work flawlessly For me it looks a bit too detailed to pass as an official model, but personally I like the added details like the manual chute for the rocks
