Troubleshooting
Status can be judged by LED indicator and emitted sounds. The documentation provides fault symptoms, possible causes, and solutions for self-check and operation, including items such as throttle PWM signal missing/misidentified, high throttle detected at power-on, motor circuit disconnection, abnormal supply voltage, controller hardware abnormalities, motor start failure/stall protection, short circuit/overcurrent protection, loss of PWM signal during operation, and high temperature detection.

Details
The MAD 9X12-II integrates the MC912 motor, 60A14S ESC, and 3296 propeller into a coaxial arm power system for multirotor builds.
The high-efficiency disc motor and sine-wave drive controller are designed for smooth operation and stable thrust under load.
The coaxial propeller setup pairs carbon fiber blades with a central power pack that includes red and green LED heading lights.
The MAD 9X12-II drawing provides key measurements like the 813.64 mm span and Ø113.68 mm hub diameter to help confirm fitment.
The MAD 9X12-II KV100 setup lists key specs like 12S LiPo voltage, 32-inch prop options, and a 60A FOC ESC with DroneCAN support.
MAD 9X12-II 100KV test results on a 12S setup list throttle-by-throttle data for thrust, RPM, power draw, torque, and efficiency for both top and bottom configurations.
The included ESC troubleshooting guide pairs LED indicator patterns and beep codes with likely causes and setup fixes.
