The precisely balanced rotor guarantees users low vibration & noise during the motor’s 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.
