Fun fact. Designing GBC Modules from existing LEGO Sets can be complex. To connect them all together in a loop and complete the drive system with correct speeds is of a whole new level ingenuity. Our NEW upcoming GBC 21 – 42055 C Model is no difference but we succeeded again. For the drive system we almost used all the gears that come with the LEGO set. It’s gonna be awesome! https://pv-productions.com/product/lego-gbc-21-42055-building-instructions/
