The guides are written to help a reader complete a fold, diagnose a recognizable flight pattern, or carry out a comparison. An article should leave you with a procedure you can try and a clear way to interpret what happens.
Where the instructions come from
All 44 plane tutorials follow the current folding sequences in the app's catalog, including the refitted nose and wing geometry. Plane-specific shape checks explain where to look for mismatches. Letter-sized measurements are labeled; the app provides the corresponding A4 sequence. Troubleshooting guidance follows the app's Flight Doctor, with reminders to check symmetry and repeat a throw before changing a plane. We explain the limits of these starting adjustments instead of prescribing one trim setting for every design.
Sources and examples
For aerodynamics, we link to relevant primary educational references such as NASA's glider guidance. We write our own explanations and experiment procedures. A worked numerical example is labeled as illustrative; it is not a claim that we measured that result.
What we do not claim
We do not claim a plane is the world's best, guarantee a distance, or imply that every recommended adjustment has been physically tested across every paper type. Simulation output is identified as simulation. Practical advice should be checked against the actual flight of your plane.
Changes and corrections
Each guide shows its publication date. When an instruction or conclusion changes materially, its modification date is updated too. To report an error, email hello@foldandsoar.com with the page address, the passage, and a description of the issue. We can compare it with the app's instructions and revise the guide where appropriate.
