4PCS Reinforced 7-Inch 3-Blade Propeller Assembly 7040

5mm Shaft (2 Pairs)

4PCS Reinforced 7-Inch 3-Blade Propeller Assembly 7040 Polycarbonate Rotor For Professional FPV Drones and Power Systems, 5mm Shaft (2 Pairs)

The Reinforced 7040 Series 3-Blade Propeller is a professional-grade rotor component engineered to sustain optimal structural and power performance for 7-inch FPV racing drones, long-range flight platforms, and specialized inspection missions. Leveraging high-tenacity polycarbonate and a 7x4x3 aerodynamic structure, this assembly delivers stable physical thrust and superior response.

Core Technical Specifications:
– Model Specification: 7040 (7-Inch 3-Blade)
– Pitch: 4.0 Inch
– Shaft Aperture: 5 mm
– Hub Dimensions: 13.5mm Diameter / 6.8mm Thickness
– Material: Industrial-Grade Reinforced Polycarbonate (PC)
– Mass: 9.7g per propeller
– Application Profile: System Observation, FPV Long-Range Cruising, Professional Dynamic Missions

The propulsion architecture has undergone extensive mechanical tuning for high-frequency operational environments, ensuring superior integrity and structural consistency under varied flight load conditions.

Package Included:
– 2 x Reinforced Clockwise Propellers (CW)
– 2 x Reinforced Counter-Clockwise Propellers (CCW)

  • Precise Fit and Professional Specs: These 7-inch (7040) specification propellers adhere to professional mounting standards and are specifically optimized for long-range FPV platforms and performance power systems. The precise 5mm hub configuration is engineered to interface with standard brushless motors, providing an accurate mechanical solution for professional builds and maintenance.
  • Advanced Material Integrity: Constructed from reinforced polycarbonate (PC) materials, delivering superior mechanical toughness and physical fatigue resistance. With a mass of 9.7g, the robust three-blade structural design ensures the maintain stable mechanical consistency under high-RPM , providing sustained support for high-dynamic cruising.
  • Optimized Propulsion Logic: The aerodynamic layout with a 4.0 pitch has undergone extensive tuning to enhance thrust efficiency and operational smoothness for 7-inch drive systems during long-range missions. Optimized thrust curves ensure the propulsion system maintains exceptional operational feedback and linear power response when supporting system observation tasks.
  • Reliable Structural Stability: Featuring a hub diameter of 13.5mm and a thickness of 6.8mm, the assembly is reinforced to effectively absorb operational stress generated during high-frequency rotation. Stable physical properties facilitate operational continuity during complex task profiles, effectively maintaining hardware mechanical and ensuring drive unit integrity.
  • System Integration: The package includes 2 pairs (4 pieces) of reinforced propeller sets, ensuring rigid physical coupling with standard motor shafts. This consistent integration logic simplifies the assembly procedure and reduces mechanical wear within the propulsion train, ensuring the aircraft maintains reliable dynamic balance across diverse mission profiles.
