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 this 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.
