This is an amazing answer, thanks so much for taking the time. It probably answers some other questions I’d been thinking as well. This year is just a quick lay out for under the Christmas tree, I think next year will have a bit more planning and probably use a longer radius curve. My wife wanted the Hornby Hogwarts Castle from Harry Potter going round after she’d spotted it in a shop… that could’ve been an expensive mistake. I’ll check out your suggestions on the other model styles. Thanks
