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.
