The DJI Propeller R3390 is a high-performance folding propeller engineered for professional industrial and agricultural unmanned aerial vehicles (UAVs). With its large 33 × 9.0-inch aerodynamic profile, lightweight composite construction, and folding blade design, it delivers efficient thrust, stable flight characteristics, and long service life for DJI heavy-duty drone propulsion systems.
The advanced aerodynamic blade profile is optimized through extensive engineering analysis and flight testing, with every aspect of the blade geometry — airfoil shape, twist distribution, blade width, and pitch angle — designed to maximize lift while minimizing drag. The large diameter produces substantial lifting force for medium and heavy payload UAVs, enabling efficient transport of spraying systems, mapping equipment, multispectral cameras, and thermal imaging devices.
Manufactured from high-strength composite materials, the R3390 balances rigidity, durability, and lightweight performance, minimizing blade deformation under centrifugal loads while absorbing minor impacts and vibration. The quick-release folding mechanism automatically folds the blades alongside the drone arm during transport and storage, and both CW and CCW versions are available for complete propulsion setups.
