eric trax posted a topic in LEGO Technic and Model TeamThe idea for the B model in the form of the Liebherr PR776 appeared in December 2019. Unfortunately, I had no experience building alternative models, so first I assembled a simpler model - skid skidder based on Bobcat T870. Having already some experience and, what is important, knowing what I can afford during the build, especially the list of parts, I made it. I tried to make all the functions and as much as possible to make the original look like this The tactic I chose when designing was to check whether the new engines and hubs would fit in the 1:18 scale model (scale to the wheels). In fact, when I put the first hub between the tracks and the drive motors, I ran out of space in the chassis. Another problem was the new, long actuators. While they are great for lifting the blade, they are too long for the ripper. In the original, these actuators are very short. To keep the dimensions of the ripper I had to build them much more into the center of the model. This added another space problems and the need to place one of the engines at the bottom of the frame. I really wanted the model to resemble the original as much as possible, so I started building with modeling the hood. Then I took care of the blade, which consumed almost all DBG system bricks. However, the basic curvature was pretty nice. Its appearance gives a lot of visual effect. The problem was the shape of the cabin. I don't know who designed the original, but there is a suspicion that he was drunk. Fortunately, it was possible to create a quite realistic cabin and interior. It is masochism to use the Control + system on models of this scale. How to build in two large hubs so that you can replace the batteries from the bottom and turn them on from the top? The first hub is located under the hood between the tracks. From the bottom we have access to the battery and we activate it with a clever switch in - the left platform. The second hub is located directly under the cabin. This can be easily folded back to gives access to the control hub and turn it on using a switch in the cabin The model does not have a realistic suspension. I resigned from it because the model weighs over 3 kilograms. I really wanted it to be stable and the tracks did not make such terrible sounds as the model A while driving. There are, however, four tilt carts that make it easier to climb over obstacles. Some technical data: Length: 46 cm, Width: 25 cm, Height: 23 cm, Weight: 3.04 kg Drive and steering – 2x XLarge C+ motor Ripper – lift (Large C+ motor) tilt (Large C+ motor) Blade – lift (XL C+ motor), tilt (Large C+ motor) I wanted the application configuration to be as simple as possible, so I also created a custom profile in the buwizz application which greatly simplifies the configuration of the model control. I also made a layout to make the control panel pleasing to the eye.

So I've recently built model B from scratch (taking everything apart and not using anything from model A) of Lego 42043. And after I finished itI noticed that my pneumatic pump is not working as intended, it stutters and then stops. I though it may be some pipes in crane that is blocked so it cant pump, but no everythings fine, then I rechecked gears and loosened them so they make as little friction as possible yet nothing changed... In model A the pump is going so fast even when its not pumping air to the crane, but in model B (the one I built) it cant even pump for 2 sec when connected to crane. So what im asking is, has anyone gotten this problem where in model B the air pump is not working as intended and is there a fix without rebuilding the whole trailer?
