The iFlight XING 1504 is an ultralight, high-performance brushless motor specifically developed for 3-inch to 3.5-inch micro-drones, such as the AOS 3.5 and ProTek series. Designed in collaboration with FPV specialist Patrick Xing, this motor brings the durability of the "NextGen" XING series to a compact form factor. Its standout feature is the Unibell (one-piece) rotor construction, which significantly improves crash resilience and structural integrity compared to traditional two-piece designs. For university aerospace research and tactical sUAS developers, the XING 1504 offers a precision-tuned power-to-weight ratio that is ideal for high-agility reconnaissance platforms.
Internally, the motor is equipped with premium NSK 5x2x2.5mm bearings and high-grade single-strand copper windings, ensuring ultra-smooth throttle response and electrical efficiency. While often discussed in the community for higher voltage builds, the official manufacturer specification lists an input limit of 16.8V (4S), making it a "beast-mode" solution for high-KV 4S setups. Its 9x9mm micro-mounting pattern and 1.5mm shaft are industry standards for modern micro-frames, allowing for seamless integration with a wide variety of lightweight propellers. Whether you are building a sub-250g "long-range" micro or a high-speed cinewhoop, the XING 1504 provides the industrial reliability and "punch" required for mission-critical micro-flight.
