  1. What a breathtaking design! I wish you the best of luck getting the real version built, and I am looking forward to see it. And now that you are taking on a very expensive build, I would also love to see the exhaust in the back be chromed - it is a great detail of from the real car.

    [WIP] Straddle Carrier

    I am explaining how it is supposed to work at 3:01 in this video: In the video I also show the tracked version in action. The major change from the wheeled version is fo course... The NXT motors fit in nicely. I'm sure PF and PU motors would do too. The reason I am using NXT motors is that I want to make it "smart" and either be able to pick up containers automatically, or be remote controlled using Bluetooth devices. For now it is powered by PF since it is super easy and quick to implement for testing. The spreader has been updated: The red liftarm is the crucial part that makes the mechanism work. I causes the "clicking" mechanism that makes the fingers in the corners lock and unlock. I will make a separate post with how this works. The lifting mechanism is super simple: The white wheels cause the spreader to stop in top and bottom positions without destroying the parts. Now I will look at that new simpler error-correcting steering mechanism for the red wheeled version.

    [WIP] Straddle Carrier

    Holy moly Miha! Your straddle carrier looks amazing! You are clearly going for an ultra-realistic look with the lifting mechanism, how the spreader is able to pull out and just overall aesthetics. It pains me that it did not succeed. I have made some tests, and I have bad news. The slack in LEGO pieces makes the legs stray to the sides or inwards even when the steering is locked in the straight position! For this reason active steering adjustment is necessary, and not even a 6-wheeled approach with single-purpose wheels will work. @pleegwathas mentioned using Mindstorms, but it is not that easy to detect and account for the legs straying to the sides. My latest attempt is the following: I am using the gray frames to "error-correct" the steering. The idea is that when the legs stray outward, the gray frames (not being connected to the legs) will pull the steering so that the wheels turn inward. Similarly they will correct to the other side when the legs go inward. Unfortunately the steering is too heavy, and this approach does not work either: The issue seems to be the complexity of the steering. The rotating sections in the middle cause Ackerman steering geometry to be introduced, but they also seem to be cause too much slack and resistance. I will give it a last try with an even simpler steering mechanism. I'm glad that I am not the only one who got that idea! I thought the same, and was about to build a super rigid top section. However. It is the spreader which causes the main rigidity of the legs, since it is far lower placed. Unfortunately the soft nature of the liftarms makes the whole structure very flexible even with the spreader in the lowest position! I have tested your theory by locking the steering and all the wheels were in the neutral/straight position. Even like this, the legs strayed to the sides as seen in the first picture. Having an ultra-rigid superstructure might help with this, but then we would be talking about something like 9 studs wide solid legs. I am instead looking at another alternate approach: I know this throws realism out of the window, but I would like to see if I can make the model work so that it is fun to play with.
  4. I'm so happy that the rules allow for a Segway, Velo Solex, and even the Gyro-X!

    [MOC] PF Forklift

    It is great to see this type of "dual lifting" mechanism again. Lego did it 8415, but I like the look of your far more. Good presentation video too.

    Help Me Save Power Functions!

    And is easier to turn on and off for new users who just want to use a remote with the basic hub. But then there are all of the disadvantages of, and oh boy! Range of remote, number of channels, servo motor limited angle and position, etc. If anything, a petition should be made for interoperability like PF has the 9V adaptors in all extension cables, NXT is compatible with EV3 and has 9V adaptor cables, etc.
  7. Alright. I have to change my position again and agree to disagree. The photo is used to show the differences in length-wise offsets for the positioning of the wheels, windscreen and other design elements. The slight difference in angle is negligible and the picture can absolutely be used for a comparison of the two.
  8. No. I hate to disagree, so I will have to change my mind and agree with you that the wheels should be even bigger. This is a long thread, so it is understandable that you didn't want to browse back. For this reason I am reposting the picture I used to prove that the wheels are already too big. Now that we agree that the wheels should be even bigger, how big do you think they should be?
  9. If you look back in the thread, you can see that the wheels are too big!
  10. I knew I had another Claas Xerion lying around somewhere, so I was able to rebuild this amazing set... and show that the attachments work: The Disc Harrow obviously works. I doubt anyone had doubts about that. By adjusting the Shutter speed, the rotary tiller spins nicely from the PTO: But the most fun is of course when looking at the Hay Tedder doing its thing: Building instructions as seen in my previous post are free on https://brickhub.org
  11. It seems off, so I took a closer look where the LEGO model is compared to the real race car. You are correct that the proportions are pretty accurate. It appears to be the missing windscreen that makes the nose look longer and threw me off when seeing it from that angle. The big problem seems to be the wheel size. They are too big, which is the reason for the right height issue and the stumped rear. Also. The rear lights should be places a stud higher:
  12. I know where they are going with this, but it is misleading to formulate it like this, since Technic was released in 1977. Overall I'm super stoked by this set, and I will get at least 1 of them. The only downsides I see are: - Missing gearbox (as many other mention. But it would be a challenge since the real car has a 6 speed + reverse gearbox) - Missing air jacks. Why is LEGO not reintroducing this cool feature? - Rims should have been flat silver IMO. - Front overhand and proportions are off, causing the LEGO model to lose the beautiful MR proportions of the real car. (I will make a new comparison using Griddy so you can see what I'm talking about) - Wrong parts being used for the rear lights. The real car has a light signature with rings which the carpet runners completely fail to capture. - Incorrect name. This is not a "488 GTE", but rather a "488 GTE EVO". Ferrari used the EVO version in the 2018/2019 superseason of WEC which you can recognise from the clear headlights and livery.
  13. I have created three new attachments to be used on the Claas Xerion. Rotary Tiller It can be opened: And is powered by the PTO with sides that click in a simpler way than on the official set: Building instructions for it can be found here: https://brickhub.org/i/694 Disc Harrow It is a fairly simple offset style disc harrow. I selected this style as it allows for more discs than seen on the more normal X-style. The instructions can be found here: https://brickhub.org/i/693 Hay Tedder The sides can be lifted. Please don't run the PTO when in this position: Small turntables are used to allow the wheels to be mounted below the rotating parts: And the side lifting mechanism is also fairly simple: Building instructions for this can be found here: https://brickhub.org/i/695 Unfortunately I killed my own Claas Xerion in order to get parts for the John Deere tractor, but the PTO is the same and the implements work on both tractors in exactly the same way.

    Decreasing number of MOCs

    It is one of my own threads, and I don't want this to become a plea like "please comment on my MOC". It was merely to illustrate a counterpoint to one of the opinions displayed in this thread. You are moving the goalpost and misrepresenting the example. The example was a rebuttal to your initial comment that a good MOC would receive feedback. Nothing else.

    Decreasing number of MOCs

    Yeah, that one was pretty grafting. I have another example. There is a model of a race car posted on EB which received the attention of the driver of the race car on Twitter who requested it for an official LEGO set. It received shoutouts and articles from FIA WEC (the race organisers of WEC races, including the biggest race in the World, Le Mans), dailysportscar.com (One of the biggest magazines covering the racing world), The LEGO Car Blog, Metropolitan Magazine, and SportsCar En Español (my Spanish is not good enough to know what they are all about, but hey... they made articles with shoutouts for this particular LEGO model!). How many comments did the MOC attract on Eurobricks where it was presented including the WIP photos? Zero. And according to @proran it was therefore not a good MOC. Now @proran might be right. But as I said initially. When people put in a lot of effort in their content and get no feedback, do not be surprised if they next time only post elsewhere.
