  1. Fantastic idea for the b-model. I love how it looks, just like original :)
  2. It looks very good as Bmodel. Nice build!
  3. Yes, there is a difference in the shape of the tire. By using power puller rims, you make the tire look bigger. Below is a comparison: The axis is 11 studs wide. The joint CV you are writing about is 4 study wide. There is no space for the differential and its mounting. Besides, only one wheel, not two, comes out. Your calculations have a fundamental error. Dimensions 3300 to 4023 mm do not describe the axle width. The wheels do not match the width of the machine. They are narrower. The right wheel on a real machine extends about 40 cm ;) Finally, 40 cm is 3 studs in 1:17scale. Perhaps, I will limit axle extend to two studs and use the zetros shaft. Thank you. Hopefully there will be some interesting discussions here during the building process. I tested this solution. It seems good, however, it creates a problem with the mounting of the axle-extending actuators. I liked this solution and maybe I will come back to it again if I have a better idea how to build this element.
  4. I tried to build a version with these shafts. However, they may extend by two studes. I needed three studs. I don't want to use 3D printed parts. I also tried to use z8 gears without friction but was not happy with the effect. Perhaps before I finish building this model I will make an axle with two wheel drive.
  5. It's been a while since I presented my last large model - the Krone BigX 770 forage harvester. I decided that this time I would start building something more demanding. It will be a potato harvester Grimme 270. Where did this idea come from? On one Bricklink order, a seller made a mistake and sent me three Power Puller rims. I took that as a sign to start building this three-wheeled monster. There are several configurations of this machine with different wheels and even a track only on the right side instead of the wheel. I decided to build a classic version with wide tires. The biggest advantage of this model is that the engine and mechanisms are in the thrust on the right. It's the perfect place to make use of it and use it as the main frame for the entire model. It's the perfect place for all engines. This is very important because I would like the combine to be solid and able to operate at exhibitions. I would like the harvester to actually harvest "potatoes" that will be brick round 1x1 or small beans. This is why I gave up building the larger Varitron 470 terra track. The 270 version gives you a better chance of it running like the real thing. However, this is a huge challenge. The model will use the Power Functions system controlled by 2 or 3x Sbrick. This is my favorite setup. The combine will have 10 functions and will use 8-11 channels depending on how I manage to place the mechanisms. This will be: - driving - turning - rear axle width extension - lifting the collecting belt - control and drive of the haulm cutter (this is the front tool) - unfolding the main tank - unloading belt drive - fine haulm conveyor drive - belts at the rear - main belt drive - lighting I started the construction with the most difficult element - the rear axle. I really wanted to keep the width change function. After building a dozen or so versions, I finally decided on one without a differential and with one-wheel drive. Instead, it has two actuators that stabilize the right wheel. This is very important because about 70% of the model's weight will be loaded on this axle. The GIF below shows how the resize function works. You won't have to wait that long for the next updates. This model is one of the two major projects for 2022 :)

    42130 - BMW M1000RR K66

    Regret, sorrow, millions of broken women's hearts. I thought about Sariel and RacingBrick's review for two days, because I was waiting for this set a lot. But when I saw the pictures, my hands just dropped. I have two theories. The first is that LEGO has such a rank in the market that it will sell any branded poop as a set, or the second is that the people at BMW who approved it were drunk. I can't take my eyes off this mega massive, heavy and completely out of proportion front. The front wheel looks as if the springs in the front suspension have failed. How can such massive front spoilers be built? I know it's a big model but it looks funny. The fairing on the front wheel is also too large. I was going to buy this model for a work shelf, but I don't know if getting nervous while looking at it in the office will have a positive effect on my performance. I will skip the issues of falling off elements or bending front forks. Why do I have the impression that this is a very delicate model? It falls apart just by touching. The rear wheel stand does not actually stabilize the motorcycle. And finally. Now it will probably be the norm next years. What does the Lego company do when the model does not look completely? Prints a sheet of 124523814 stickers and disguises strange solutions and lazy building. I would understand it if the fairings were very neat like on a Ducati motorcycle. This is not the case here. For quite some time now quite a few models built this way. How long is this company going to make idiots out of its customers? It breaks my heart because I really wanted to buy this motorcycle. Do not write to me, please build better because I am not creating an exclusive model for 200 euro, because for a BMW sticker. I'll stay with my Ducati. It's smaller and that's where it was possible to make a cool looking and durable model. The rims, rear shock and windshield are beautiful.

    Technic 2022 Set Discussion

    This is cute and radically stupid. Another random mini model published in order not to lose the license. I mean the Mini Xerion and this charger. Where are you going Lego?

    I think that will be long term series as supercars. They will use new rims an tires in next UCS motorcykles :)
  9. 3rd october. There's still no Control+ update for android users. Price - $449.99 Lego You're joke last two years.
  10. So... it has one Technic hub, four engines and a gearbox. What a plot twist.
  11. Believe me, the difference is big. CAT is on a larger scale. Still, the PR 776 has much better overall proportions. I have photos but I will share the comparison later.
  12. The model will be very heavy. My Lexion weighs almost 5kg. I had to put the Unimog tires into the Power Puller tires because they were falling off the rims. Agri tires are much harder and this shouldn't be a problem. do you mean header lifting? If so, the L motor will be too weak. Check available header widths. Your model uses the widest headers which will be very heavy. I wanted to use the pneumatic functions but gave it up. I prefer LA. They are much more precise and take up less space.
  13. Well. The 107 tires you choose, compared to the wetness of your Terra Trac, are the largest size (by my eye). These are the equivalents of 500/85 R 34 tires with a diameter of 1750 mm. This is a scale of 1: 16.5 as mentioned in @1gor. Technic links are equivalent (on this scale) to 635mm tracks. This gives a total width of 3490mm. Lego tires are a bit wider than the original ones so I wouldn't change the width of the rear axle and built all the elements to the width of 27 studs. Below, I have scaled the basic elements based on the 360 view available on the manufacturer's website. Here you will find all the basic dimensions you should follow. Select the rest that like it looks just good due to the shape of the bricks. Hope this will be helpful :)
  14. You are quite right. Downloading additional instructions is not as obvious as taking the second book out of the box. However, I think that the perception of Lego bricks has changed as well. It used to be a creative toy from which children created many different toys. Now it's also about styles for adults aged 20-40. Thank you for appreciating the idea of inverting the actuators. It is very simple, but it became the impulse to build this model. Over the past several years, Lego Technic models have become very similar to real machines, but they still have problems with the correct scale dimensions. When building, few people pay close attention to the scale, but this is the key to getting a realistic MOC look.
