7. Frequently Asked Questions
What is the maximum takeoff weight for a quadcopter using X8108 motors?Four X8108 motors provide approximately 21.9kg total thrust (4 × 5.47kg). For safe operation with 50-60% throttle hover, the recommended takeoff weight is 10-14KG. This allows for 40-50% power reserve for climbing and maneuvering.
What propeller is recommended for X8108 97KV?The optimal propeller is 28*8.4 (28x8.4 inches). For custom applications, 26-30 inch propellers are compatible with appropriate tuning.
What battery voltage should I use?Voltage range is 12~60S. Our test report used 37V (≈9S-10S). For higher power output, higher voltage batteries can be used up to 60S (≈216V).
