STL and STEP files of FPV and multirotor drone propellers: 3-inch cinewhoop, 5-inch freestyle, 7.5-inch long range, 10.5-inch cinelifter, 13-inch X-class and heavy-lift drones.
Each propeller is designed and computed with the Heliciel software using blade element momentum theory, at the hover speed measured on a test bench for a common motor of its size. The product page gives the computed thrust, torque, power and structural check, with the performance curve.

Model designed and computed with the Heliciel software (blade element momentum method, BEM). Design point: 7,815 rpm in hover, 50 % throttle on a 3115 900 KV motor on 6S.
Model designed and computed with the Heliciel software (blade element momentum method, BEM). Design point: 7,815 rpm in hover, 50 % throttle on a 3115 900 KV motor on 6S. 8° rake.
Model designed and computed with the Heliciel software (blade element momentum method, BEM). Design point: 7,815 rpm in hover, 50 % throttle on a 3115 900 KV motor on 6S. Square constant-chord blade (heavy load).
Model designed and computed with the Heliciel software (blade element momentum method, BEM). Design point: 6,490 rpm in hover, 50 % throttle on a 340-350 KV motor at 46-48 V. Winglets (6 % of radius, canted at 75°).
Model designed and computed with the Heliciel software (blade element momentum method, BEM). Design point: 6,490 rpm in hover, 50 % throttle on a 340-350 KV motor at 46-48 V.

Model designed and computed with the Heliciel software (blade element momentum method, BEM). Design point: 4,500 rpm in hover, about 50 % throttle on a T-Motor MN4014 400KV motor on 6S.
Model designed and computed with the Heliciel software (blade element momentum method, BEM). Design point: 4,500 rpm in hover (T-Motor MN4014 400KV motor on 6S, about 50 % throttle). Four blades with rounded tips and skew: more thrust than the two-blade version at the same speed.
Skew (scimitar blades) and rounded tips are sought to reduce noise; winglets reduce tip losses according to Heliciel's model; the square constant-chord blade carries more load at the same speed; rake tilts the blade backwards.
The product page gives the material with which Heliciel checked the strength at the design point (PETG, glass-filled PA6 or carbon laminate). A printed propeller must be checked before use and never run above its design speed.
The complete propeller as a full-definition STL with root fillet, STEP surfaces (complete propeller and one blade) for CAD, the Heliciel .hlc project and the computation records.
