Hello everyone, sorry if this is a very beginner question but I just reached the final step of my millennium flerken and I’m struggling with the prop installation and I’m confused whether I’m missing a piece or if it’s supposed to just be the prop and then the nut securing it on. Also it’s quite difficult to get the nut on and the nut doesn’t go on very far unless I used a lot of force which I’m not sure I should commit to. I’ve attached pictures of just about how far the nut goes on without too much force. Please let me know if I need to buy something else or what I should do…
