Overview

The GEPRC SPEEDX2 2809 V1.1 Motor (1450KV / 1280KV options) is designed for 7–8 inch long-range FPV builds. It uses a stator with 0.2mm Kawasaki silicon steel for efficient magnetic flow and N52H magnets for improved high-temperature resistance. The motor uses a 19mm x 19mm mounting pattern.

Key Features

  • New Version, Superior Performance
  • SPEEDX2 Series Simple Appearance Design; unique appearance, science fiction design elements
  • Integrated Outer Rotor: using 7075 aviation aluminum alloy, high-precision CNC integrated
  • Exquisite Color Matching: overall dark appearance with red edge
  • High-strength motor structure: rotor edge structure conforms to the load-bearing mechanical design and has strong impact resistance
  • Efficient Magnetic Circuit Scheme: high-quality N52H magnetic steel is used to prevent high temperature demagnetization
  • N52H arc-shaped magnets: strong magnetism, stable power output and high efficiency
  • Energy-saving stator: low heating, improving work efficiency and endurance; low energy consumption
  • Damping O-ring: reducing motor vibration and improving bearing lifetime
  • 5mm output shaft carburizing heat treatment: high strength and good stability
  • Reinforced base: high structural strength
