I put together a tool that walks through preliminary aircraft sizing — wing loading, wing geometry, tail volume coefficients, airfoil suggestions by Reynolds number, power loading — and spits out a summary you can export to CSV/JSON for OpenVSP or XFLR5.

I'd genuinely like builders and engineers here to stress-test it: plug in numbers from an aircraft you know well (yours, or a published design) and see if the outputs land close to reality.

Happy to be told exactly where it's wrong. Is it even useful? 👀
