The precisely balanced rotor guarantees users low vibration & noise during the motors high-speed rotation. The maximum thrust of up to 1. 25kg provides sufficient power for fav drone(s). Stator, rotor and shaft made of high-strength aluminum alloy greatly improve the shock resistance of the motor. Eight-bladed centrifugal fan reduces operating temperature of the motor; clear rotation direction mark on the motor case helps recognition and installation.
