Ok, I got this model as a Christmas present. And like the others, I had some problems. My rubber bands are too thick to fit in the wheel slots and also too big. They should have been 60mm but they are 80mm so they are a bit longer especially for the final drive section. 2. The winding system does not work. I traced and took it apart 4 times just to make sure everything was fine and it was. So mine will be desktop. I'm still working on it, still a lot of work. I only wish ugears would add a support line or at least an email address to the instructions. This is a beautiful piece to build attention to detail. Parts are easy to assemble if you use the right tools. as an experienced builder. This requires a lot of patience. And time. But I recommend it.
