FPV drones · 10 to 10.5-inch cinelifter
cinelifter drone propeller 10.5 in, 5 blades (square constant-chord blade (heavy load))
Model designed and computed with the Heliciel software. Design point: 7,815 rpm in hover, 50 % throttle on a 3115 900 KV motor on 6S. Square constant-chord blade (heavy load).
The pack contains the complete propeller as a full-definition STL, STEP surfaces (complete propeller and one blade), the Heliciel .hlc project and the computation records. It also contains the same propeller turning the other way (STL and STEP).

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.
