7. Frequently Asked Questions
What is the maximum takeoff weight for a quadcopter using X13815 motors?Four X13815 motors provide approximately 115.6kg total thrust (4 × 28.9kg). For safe operation with 50-60% throttle hover, the recommended takeoff weight is 40-60KG. This allows for 50-60% power reserve for climbing and maneuvering.
What propeller is recommended for X13815 100KV?The optimal propeller is G40*13.1 GF (40x13.1 inches). For custom applications, 38-42 inch propellers are compatible with appropriate tuning.
What battery voltage should I use?Voltage range is 12~60S. Our test report used 50V (≈12S). For higher power output, higher voltage batteries can be used up to 60S (≈216V).

What ESC is recommended for this motor?We recommend a 120A-150A FOC ESC with CAN or PWM input, supporting 12S-60S input voltage.
What is the thrust-to-weight ratio of this motor?The X13815 achieves an exceptional 24:1 thrust-to-weight ratio (28.9kg thrust / 1.2kg weight).
What makes the 36N40P configuration better?The 36N40P configuration provides smoother torque output and reduced cogging compared to 30N40P, resulting in better low-speed control and lower vibration – ideal for aerial photography and sensor-carrying platforms.
What is the motor's IP rating?The X13815 has an IP54 rating – dust protected and splash resistant. IP68 sealed version available upon request.
Do you provide custom winding (other KV)?Yes. KV can be customized from 60KV to 150KV. MOQ applies. Lead time 30-40 days.
Is there a test report for each motor?Yes. Individual test reports including no-load current, vibration analysis, thermal imaging, and full load thrust verification provided for industrial orders.
