The curves here are the Fast model, which every account and every visitor runs without limit. An account also runs the Full model, which solves a database propeller from its measured blade geometry.

Engineering aid — ThrustLab results are physics-based estimates, not certified data. Always bench-test and independently validate before committing a real build to flight. Not for safety-critical or certification use.
