The A2212 2450KV is a high-speed brushless outrunner motor designed for quadcopters, multirotors, and RC aircraft where a lightweight power plant with high RPM per volt is required. Its 2450KV rating means the motor spins approximately 2,450 RPM for every volt applied, making it suitable for 2–3S LiPo batteries and small-to-medium propellers in the 5-inch to 10-inch range. The motor uses a 12-slot, 14-pole outrunner configuration with a 22mm stator diameter, and its 3.17mm hardened steel shaft runs on dual ball bearings for smooth, vibration-resistant operation.

The A2212 2450KV is built for direct-drive propeller applications. With a 1045 propeller on 3S LiPo, it produces approximately 1,300g of thrust at wide-open throttle, while a 0945 propeller yields about 850g and an 0845 propeller about 750g. The motor’s maximum current capacity is 12A for 60 seconds, with a recommended continuous operating current of 4–10A, and a 30A ESC is advised for reliable headroom. The motor weighs approximately 47–55g depending on accessories and manufacturer tolerances, and its compact 27.5 × 30mm body fits standard quadcopter arms and motor mounts.

The A2212 family is one of the most widely used brushless motor platforms in hobbyist and educational drones, valued for its low cost, broad parts availability, and predictable performance. This 2450KV variant is optimized for smaller, higher-speed propellers and lightweight airframes, making it a practical choice for FPV quadcopters, small fixed-wing models, and DIY multirotor projects that need a balance of thrust and weight.

A2212 2450KV brushless motor Application

  1. Quadcopters and multirotors in the 300–1000g class using 2–3S LiPo batteries.
  2. Small fixed-wing RC aircraft and flying wings requiring a lightweight outrunner motor.
  3. FPV racing and freestyle drones with 5–6 inch propellers.
  4. DIY drone kits and educational multirotor platforms.
  5. RC boats and hovercraft projects needing a compact, high-RPM brushless motor.
  6. Replacement or upgrade motor for A2212-based airframes and trainer aircraft.
