This is the KDE Direct 4012XF-400 High Performance 24-Pole Brushless Motor. The KDE Direct 4012XF-400 Multi-Rotor Brushless Motor is an extremely efficient and powerful motor for numerous multi-rotor and UAS heavy-lift applications, and was designed to bring high-quality and vibration-free motors to the market. The motors are designed with performance and durability in-mind, with features unseen in the current market: (1) high-grade, 240C (464F) high-temperature solid-core copper windings for failure-free operation in extreme-climates, (2) Japanese-built, 0.2 mm silicon-steel stator laminations and Kevlar tie-wraps for high-efficiency performance, and (3) triple-bearing supported, ABEC-7 bearings for maintenance-free and worry-free flying for hundreds of hours. These are just a few of the advantages built-in to these motors, and every detail of the motors was scrutinized to produce the absolute best available; for a wide-range of flight applications.


  • 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 (240C/464F), 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 (200C/392F), silicon-wire power leads come pre-soldered with 24K bullet connectors for easy, hassle-free installation.
