Power Type: 18S | 14S What's in the box? (1) Integrated ESC+Motor *Propellers sold separately Learn more about X13 Power system > Overview Spec Download The XRotor X13 brushless power system is a robust plant protection system designed for 25-27kg/rotor single-rotor loads, with more than 53kg of maximum thrust. It is suitable for 50mm carbon fiber tube arms and is IPX6 waterproof, capable of withstanding rain pesticieds, salt spray, high temperatures, sand/dust, impacts, and mud/sand. Featuring FOC vector control and PMSM-based algorithm optimization, the system combines digital and analog throttle for increased flight stability, plus power-on auto-detection and safety functions such as voltage abnormality protection, over-current protection, stall protection, and others; all data is transmitted via CAN, and faults are logged for better analysis. 2 models available - 45KV | 60KV Recommended Takeoff Weight: 25-27kg/axis Total Weight: 2800g Maximum Thrust: 53kg+(54V, Sea Level) Operating Temperature: -20°C-50°C Powertrain Arm Tube Outer Diameter: 50mm Protection Grade: IPX6 Total Weight: 4060g( INC. prop) upport throttle Frequency: 50-500Hz UAV Integrated power systemThe whole power system has been assembled before leaves the factory. Unpack and take out the power kit to install on the rack of plant-protection plane as per the rotation direction of motor.
