Popular Science ;)

I’m working on a book of flying models made from business cards and mon ami Michel Grand (Michel, ma belle) is sending me all kinds of useful and interesting ideas. Here’s an image he found in a 1943 copy of Popular Science. We’ve tried to replicate this beautifully simple design using cards (and without cuts), but the weight of the cards rapidly becomes a problem, the model falls to the floor too quickly to start spinning. We’ll see if a solution materialises!
