Product overview
The Gemfan 1170-3 is a propulsion component for professional heavy-lift cinematography, industrial payload work and specialized commercial aerial platforms. Its three-blade architecture combines an 11.0 inch (~279.4 mm) diameter with a 7.0 inch pitch. Each propeller weighs 27.7 g and uses a glass fiber nylon composite. The design targets demanding payload applications, with an engineered thrust capability of over 5kg per propeller; this figure describes individual propeller thrust rather than an aircraft payload rating.
Integration centers on a 5 mm shaft hole (M5) and the specified 3220 motor compatibility. The physical dimensions include a 9.0 mm hub thickness and a maximum propeller width of 24.0 mm, alongside the overall diameter needed for installation planning. A reinforced hub and broad blades support the intended high-torque, heavy-load role. Each pack supplies one clockwise and one counterclockwise propeller, making the supplied product a pair of propulsion components for incorporation into a drone.
