I used to make the ones out of this book. https://www.amazon.com/gp/product/0671555510 https://www.amazon.com/gp/product/0671555510 They are a bit finicky to make, but fly very nicely. One day a friend and I were messing around and added a dumb amount of weight to the front of one. Think it was a clip his mom used to dry cloths outside. Nearly doubled the weight and put the center of balance way near the front of the plane. We expected a nosedive. Gave it a toss and it 3x'd the flight length easily. It was already fairly decent and you could easily get across a room with little changes. Now it was easily getting across his yard.
