This is an optional KDE Direct High Performance 14-Pole Multi-Rotor Brushless Motor with a 4mm Shaft. The KDE Direct 2814XF-515 Multi-Rotor Brushless Motor is an extremely efficient,  powerful motor for numerous multi-rotor and sUAS applications, and was designed to bring high-quality and vibration-free motors to the market. 


  • Industry-Leading Performance: Magnetic field simulation and years of field testing utilized to optimize power‐output efficiency and torque‐curves for multi‐rotor and UAS specific applications. The XF Multi‐Rotor Brushless Motor series produce a high‐level of performance and are built to the highest‐quality standards and manufacturing technology available.
  • Universal Propeller Mounting Pattern: All XF Series motors have dual propeller mounting profiles for use with the included KDE Direct adapters; and simple compatibility with a wide‐range of available propulsion options for easy installation.
    • M3 x 12 mm x (2)
    • M3 x 17 mm x (3)
  • Universal Motor Mounting Pattern: All XF Series motors utilize an innovative, universal mounting pattern and shaft-retaining collar for drop-in compatibility and safety with all multi-rotor designs. 
    • M4 x 25mm (4)
    • M3 x 25mm (4)
    • M3 x 32mm (3) - DJI S1000 & S800 EVO
    • M2.5 x 32mm (3) - DJI S800
  • Optimized Stator Design: Stator construction uses the hightest-grade, 0.2mm silicon steel laminations and ultra-high temperatures (240°C/464°F), pure-copper core-windings for optimum efficiency and power transfer. All winders are futher secured with a continuous, Kevlar-tie wrap around all stator teeth to reduce change of winding shorts. 
  • Magnet Bell Construction: All XF Series motors use true-grade, high-temperatures rated N40UH and N45SH Neodymium sintered-magnets for industry-leady performance. An upper magnet retaining ring, machined slots, and 360° epoxy bonds are incorporated at each magnet location to secure a permanent connection to the motor housing.
  • Silicon-Wire Power Leads: High-temperature (200°C/392°F), silicon-wire power leads come pre-soldered with 24K bullet connectors for easy, hassle-free installation.
