Hi, Hello! I'm new and very interested in reviving my old passion for building Lego fairground attractions with Technic Lego. A few years ago, I stumbled upon this thread https://www.lowlug.nl/forum/index.php?thread/15159-lego-technic-turbo-polyp-remasterd/ and have been following it with admiration. Some things are difficult for a layman to understand, but perhaps one of the forum members here has the perfect solution! I'd like to build a polyp with rotating arms, rotating crosses, and moving arms, just like in the thread above. Does anyone happen to have a readable drawing, or can make one, of the center section? The large gears that rotate in opposite directions over each other? And does anyone have experience with drag links, so that a motor could perhaps be built into the crosses instead of using the center section? I'd love to see any tips and tricks. Thanks in advance.

Thanks for the info! Do you mean a gear like the one I sent you a screenshot of below? And what about the image you added at the top of the tower? And then you could drive it with two motors, right? Hi! I understand your idea well, it's similar to the previous forum member's. My only question is, how do I get these gears to turn without any visible mechanism on the outside? I also thought about starting with the manual control and then expanding this version with motors

Hi, Does anyone know how to build the center section (see attachment) to connect so many arms? What are the minimum Technic parts I need for this? Thnkx.

Hi All, I want to build a fairground attraction from Lego Technic together with my son. We are both fans of the Nebuaz (https://www.youtube.com/watch?v=kNIfLHdXhFY) We are only looking at the technology and we can't quite figure it out. How would we get the pole/mast to turn like the original (https://youtu.be/i4XnbKoZ_A4) has. Which Lego Technic parts do we need for this? And can this be built without installing the motor in the pole/mast with a battery pack? All information is welcome, thnkx
