Product overview
The Gemfan 1045-3 is a propeller component for long-range UAV flight, with applications including FPV cruising, endurance flying and stable cinematic platforms. Its physical design combines three blades with glass fiber nylon construction, a 254 mm (10 inch) diameter and a 4.5 inch pitch. The black propeller weighs 17.8 g. This configuration targets sustained cruising and smooth thrust delivery, with precision molding used to support dynamic balance and reduce vibration during rotation.
For integration, the central mounting geometry comprises a 5 mm inner hole diameter and a 9 mm center thickness, while maximum propeller width is 21 mm. These dimensions define the mounting interface and blade envelope to accommodate in a build. Gemfan recommends a 3214 – 800KV motor for this propeller. The product is a propulsion component rather than a flight platform or airframe kit; its stated applications include both fixed-wing and multirotor builds intended for longer-duration operation.
