Overview

The Gemfan Vortex 5×7.5E / 5×7.5R is an electric propeller made from glass fiber reinforced nylon, designed for 5-inch-class multirotor drones that prioritize smooth and efficient flight performance. With a 7.5-inch pitch, it targets balanced thrust for casual racing and agile maneuvers. The E/R designation indicates clockwise (E) or counter-clockwise (R) rotation for multirotor setups.

Key Features

  • Modern blade profile and optimized airfoil geometry for efficient thrust and stable flight performance
  • Certified patented design (recognized by the National Intellectual Property Administration)
  • Frosted leading edge to enhance high-speed efficiency and reduce airflow separation
  • Anti-slip hub surface for secure mounting and reduced slippage during operation
  • CFD-optimized airfoil, ultra-thin tip design, and streamlined blades to reduce drag and improve efficiency
  • Strict dynamic balancing and factory testing for consistent rotation
  • High-toughness nylon material for durability and bending resistance
