Drone builders and racers, this is a replacement/upgrade brushless motor for your EMAX Buzz or Hawk FPV racing quadcopter. This specific listing is for the FS2306 model in 1700KV (they also have a 2400KV version). The '2306' means it's 23mm in diameter and 6mm in height. It's a Clockwise (CW) rotation motor. It's made from high-grade materials for a solid, reliable build that can handle the stress of racing. It's designed for high efficiency and works best with a 40-60A Electronic Speed Controller (ESC) and a 3-6S LiPo battery (for the 1700KV version). It's meant for 5-inch or 6-inch propellers on a quadcopter with a 200-220mm wheelbase. If you're repairing your Buzz/Hawk or building a similar spec racer, this motor is a direct fit. Just remember, it's just the motor – no prop, ESC, or battery included. A key component for keeping your drone in the air.
