Product overview
The Gemfan D2.8 Ducted PC 3 Blade 1.5mm, identified as type D2.8-3, is a propulsion component for 2.8-inch ducted FPV cinewhoop drones. Its intended work includes cinematic aerial capture, indoor filming and operation in tight spaces. The three-blade architecture uses polycarbonate, with clear yellow and clear black color options. A 71.12 mm propeller diameter and 2.8 inch pitch define its principal geometry, while each propeller weighs 1.59 g. The product is a propeller rather than a complete flight platform.
Integration centers on a 1.5 mm T-mount hole, a 5 mm center thickness and a maximum propeller width of 15.2 mm. Normal and inverted mounting configurations support different cinewhoop layouts, and the recommended motor designation is 1507. The D2.8-3 is optimized for builds using the DJI O4 HD video transmission system. Its specified maximum takeoff weight is 300 g. The aerodynamic profile and dynamic balancing are intended to reduce vibration and support smooth throttle response and stable low-speed control in cinewhoop setups.
