Fold and Soar is a paper airplane learning project: written guides for real sheets of paper, paired with the Skyfold interactive folding and flight app. The goal is to make the next fold easier to understand and the next flight more useful to observe.
What you can do here
Follow a beginner folding tutorial, diagnose a flight pattern, compare materials, or plan an experiment. In the app, rotate a plane, replay a fold, and explore the effects of trims. You can use the written guides independently; they do not require an account or a working 3D browser.
Who maintains the project
The website and app are maintained by Takayuki Hoffman. Written guidance is published under the Fold and Soar name. The app combines a paper-folding model with a flight simulation; the guides connect those tools to activities you can try with real paper.
A model and a real plane are different
The simulator represents a folded sheet and its flight mathematically. It is useful for seeing a fold or exploring a change, but hand-built planes include wrinkles, loose layers, moisture, and release differences. We distinguish simulation observations from physical measurements and do not present simulated distances as real-world records.
