PropShaper: design a propeller from your motor specs

Tell PropShaper your motor kV, battery, weight and how much room you have. It picks the diameter, pitch and blade count, checks thrust, current, tip speed and cavitation, and puts the blade on a real hub so you can 3D print it. Drone, FPV, RC plane, e-foil and boat propellers, all in the browser.

What you can do

• Get a matched prop from basic specs with Quick design
• Fit it to a sourced hub standard: T-mount, M5, T-Motor, APC, Minn Kota, 65161 e-foil and more, or edit a baseline to match your own shaft
• Shape chord, twist, pitch, skew and rake with live 3D feedback
• Start from measured UIUC propellers or Wageningen B-series marine outlines
• Check thrust, power and efficiency with blade-element momentum analysis
• Export a watertight STL free, or STEP with Pro

Built for drone builders, e-foil riders, RC boaters and anyone who needs a custom prop that no one sells.
