  1. Now it doesn't matter anymore. It has been finished. Lack of humility is never good. Good opinions about CADA should come from users who built their good sets, and not forced on others by arrogant discussions.
  2. The gearbox has the same functions as in the base model. The most important reason why I used it is the fact that the model works with the original application and there is no need to build complicated PU profiles. When the ejector is in extreme positions, the rear axle stops. Thats why I add neutral position/gear. I know it's not a perfect solution. It would be good to put the clutch there, but there were no suitable bricks and enough space. This is a simple additional function that I managed to create. To achieve realistic ejector operation, I would have to place an additional motor there, which the 42114 does not have. The gooseneck is not perfect, but I managed to strengthen it enough that it works and looks realistic. I would probably build it differently if it wasn't an alternative model. However, I am so satisfied with it that I decided to publish the model. This machine could be built much better if it were pure MOC. Then I can put all the functions needed and significantly improve the way ho it looks. However, I decided that many more people would want to build Scraper if it will be an alternative model :) There is no chance that this machine will appear as a CADA set. LEGO currently has a CAT license, so it's not possible.
  3. Read again what you wrote and think about yourself... If for you Cada viva hypercar (C61505W) is the same car as Ferrari Daytona, you need to look at these models for longer than 3 seconds. The only thing they have in common is that they are red. The rest of the models are also completely different constructions than LEGO.
  4. Hi! I just finished working on an alternative model of the 42114 set. I add large 107mm agricultural wheels to make the model look better but its possible to build it only with bricks from the set. Below are a few words about the model CAT 627K! Dimensions: Length 69cm, width 19cm, height 21cm Number of bricks: 1901 Photo of real machine for comparison: The idea to build a scraper was born almost a year ago. The project failed then, but I came back to it this year. I started the construction with a "boul" to make sure that the Volvo A60 - 42114 set has enough panels and liftarms. The next stage was the modification of the gearbox. I wanted the model to work with the official Control+ application profile. The scraper tractor has very little space for mechanics, so I split the gearbox in half and built a front axle into it. The real challenge was the bowl lifting mechanism. After a whole day of testing, I managed to build a linkage mechanism that imitates this function very well, even though it uses only one actuator. I used the second actuator to control the ejector. There is a second manually operated gearbox in the rear of the vehicle. In the first mode, the ejector moves while driving so you can empty the bowl automatically. In the second mode, the ejector is controlled manually. To change this, you just need to move the z16 sprocket. At the beginning, I was worried about whether I would have enough bricks to build all the details. So I was initially working on a scraper number 621K which does not have an engine at the back. However, it quickly turned out that I would be able to build all the details of the 627K model, such as the dummy engine or fuel tanks above the rear axle. I was very surprised that the available bricks managed to create a very nice looking cabin and front wheel mudguards.

  5. It looks a bit too short. Is the wheelbase correct? In my eye it should be 2 stud longer Besides, it looks great
  6. Fantastic mini tractor. I really like how you design the tracks. Good job!
  7. A very interesting choice! I love the design of this machine and I'm curious about the end result! :D
  8. This is rather an approximate number of bricks. The prototype had 4,459 bricks and I know that in the end there will be a dozen more, so I think it will be closer to 4,500 elements in total. More funny is this part of description: "crafted by the esteemed MOC studio Eric Trax" Now I have no choice but to start up a design studio
  9. I think that nothing bad would happen if you used identical tires on the front and rear axles :) Fair enough! I like the trailer so much that I bought bricks for a second copy to test the instructions :D I used old hubs. The turning radius is small because the tractor does not have front drive. This allows the front wheels to turn so much
  10. It's time to show something agricultural. This time it will be a rather unusual JCB Fastrac 3185 tractor and an Oehler ZDK 180 trailer. The tractor model has been on my shelf for almost two years, so it's time to show it. For comparison, a photo of the original: JCB Fastrac 3185 I must admit that the Fastrac series are some of my favorite tractors. I remember being fascinated by them in agricultural newspapers as a child. What impressed me the most was the fact that they could accelerate up to 80 km/h. These tractors are loved or hated mainly because of their appearance. The 3185 is definitely my favorite. I started building it when it was already known that agricultural tires with a diameter of 81 mm would appear with the 42129 set. The frame was built quite quickly and is significantly different from my previous tractors. I removed the front three point hitch and added a front pendular suspension. The tractor is powered by an L-motor, turns using a servo-motor, and the lift and PTO operate two M-motors. Everything controlled by Sbrick. Then I started building the cabin, which has a rather specific shape. I managed to reproduce it quite well and I am fully satisfied with it. The cabin, of course, has an equipped interior with two seats. The biggest problem I had was with the design of the tractor's hood. It has a specific arch at the front with gille and thin frames on the sides. First, I made it with a sticker, but during one of the exhibitions I came up with the idea to use rounded 1x2 plates. It was a good decision. From the beginning, I didn't plan on making a building manual for it due to the complicated shape of the cabin. I finally changed my mind. This required further corrections, but they were implemented quite efficiently. My reluctance to follow the instructions was also caused by the printed fenders that @SaperPL made for me. Not wanting to cause problems for people who would buy the instructions, I built equivalents from Lego, which increased the number of elements by 130 bricks. The final effect, especially after using the stickers, is great and I must admit that it's probably my favorite tractor now :D OEHLER ZDK 180 Such a long delay in the publication of Fastrac was also caused by the lack of a machine to complete the set. I wanted to build a construction trailer, but I decided that it would be quite similar to my previous Krampe BigBody 550. I did not have traditional trailers in my collection. I kept thinking about an unusual color that would contrast nicely with the yellow tractor. I chose OEHLER ZDK 180. I decided to build the box with 23405 panels, which imitate the sides of the dump box well. Surprisingly, the dimensions of these elements matched the dimensions of the model quite well. The dump box had to be reinforced, of course, otherwise the load would burst it from the inside. I used additional strips so that it is now very stable. The visual effect well reflects the appearance of a real trailer. The dark turquise color is slightly different from the one used in Oehler trailers, and in the photos it looks much bluer than in reality. The dump box also has a side locking mechanism that works like in a real machine. The difference is double-side tipping.The real trailer box tilts in three directions. At the beginning of the construction process it also tilted backwards, but the use of a medium linear actuator made the whole thing very unstable. Finally, the box is lifted by two small linear actuators powered by the M-motor. The maximum load I tested was 4.5 kg. I must admit that this is quite an impressive result. Another interesting fact is that I used 67.8x27 tires, which are a bit larger than they should be, but because they are wider than the 62.4 mm tires, they significantly improve the overall appearance of the model.

  11. The answer to your questions is quite simple. This model is much smaller, so it does not qualify for the MASTER series because it has much fewer bricks and is simpler to build. The box is decorated similarly to the Master series because the product is licensed and even despite its small size, CADA wants it to look as good as possible. I almost didn't notice it. The set is also intended for younger children, so the color coding is an advantage in my opinion. You can always replace the pins with black ones. I also use the color coding on my CLAAS combine harvester. Maybe it's not visible at first glance. With color coding, building is much less frustrating. I know it's the Master series, but the pleasure of building is also important to me. For example, that is why I divided the combine frame into four modules that connect into one whole to make the construction process more friendly.
  12. Fantastic compact design. What deserves recognition is that you used pneumatics, the operation of which takes up much more space in the model
  13. 2x Control Box + 7 motors + physical remote + app profile for android and iphone. All JCB logos are printed on tiles. Fun fact: I designed the operator's cabin as a completely separate model for fun during the building process. You can detach it and place it next to the excavator :) Undercarrige: Control Box + 2x micromotor for each track Upperstructure: Control Box, 2x M pro motor for arm lifting, 1x M pro motor for 2'nd arm section and 1x M pro motor for bucket tilt. Front tire 94.3x38, rear tire 75x30,5. Model have 6 working finctions powered by 2x Cada Control Box + 3x L Pro Motor, + Pro Servo Motor + 3x micromotors. Of course set have header trailer. As you can see, the sets have a lot of electronics. Don't expect prices of $150-200 ;)
  14. New inside flat Link Treads and a large Z104 bearing turntable in the JCB excavator that I designed together with @SaperPL
  15. Unfortunately I cannot confirm this. The CADA remote control does not have proportional control. Also in the CADA application there is no profile that use the servo motor.
