Performance computed by Heliciel – RC airplane propeller 12 in, 3 scimitar blades (25° skew) — Performance computed by Heliciel

Need a propeller for your own parameters?

This model was designed and computed with the Heliciel software. For a custom propeller there are two ways: the Heliciel software (Windows: computation, 3D view, STL and STEP exports), and the Heliciel MCP connector, which lets your AI assistant — ChatGPT, Claude, Le Chat and any MCP client — compute a real propeller, with a free 1-day discovery pass.
