Usage note: It is recommended to fly at the recommended take-off weight for best performance. Do not fly overweight. If the takeoff weight exceeds 1.2 times the maximum recommended value, performance and safety will be seriously affected.

Troubleshooting (Indicator Lights and Audible Alerts)

You can identify ESC status by observing the LED indicator and emitted sounds.

Power-on Self-test

Fault symptoms	Possible causes	Solution
Power-on self-test fails, motor emits a beep every 1.5 seconds, accompanied by brief yellow indicator flashes.	Throttle PWM signal lost, or incorrect throttle PWM range recognized.	Ensure throttle signal wire connection is secure; check for wire damage.
Power-on self-test fails, motor emits a beep every 0.5 seconds, accompanied by brief yellow indicator flashes.	Power-on detects a high/leaky throttle and enters protection state.	Confirm the ESC passes self-test before increasing throttle.
Power-on self-test fails, motor silent, indicator flashes yellow 4 times every 1.5 seconds: short-short-short-long.	Power-on self-test fails; motor line loop may be disconnected / possible motor winding circuit open.	Open ESC cover; check whether the three motor wires are securely fastened.
Power-on self-test fails, motor silent, indicator flashes yellow 4 times every 1.5 seconds: long-short-long-short.	Power supply voltage is abnormal.	Check whether battery voltage is normal; check whether the power cable is properly connected.
Power-on self-test fails, motor silent, indicator flashes yellow 4 times every 1.5 seconds: other flashing methods.	ESC hardware is abnormal.	Record the LED flashing pattern for reference; replace the ESC and test again if needed.
Power-on self-test fails, motor silent, indicator flashes yellow 4 times every 1.5 seconds: short-long-short-short.	Motor line voltage is abnormal.	Check if motor wires are shorted to power bus wires; check if motor wires are damaged and shorted to the case.

Fault During Operation

Fault symptoms	Possible causes	Solution
Motor does not spin after arming; spins only after throttle is increased.	Flight controller or remote controller output armed/idle throttle value is less than 1100 us.	Set throttle value greater than 1100 us; recommended 1160 us-1180 us.
Motor spins immediately after power-on and connecting to remote controller.	Remote controller throttle lock is set above 1100 us, or close to 1100 us.	Remote controller throttle lock setting must be less than or equal to 1050 us.
Power-on self-test normal, motor does not spin after arming; indicator: yellow light for 0.5 s – off for 0.5 s, motor silent.	Motor fails to start and stall protection occurs during startup.	Power cycle the ESC to restart; if problem recurs, check if the motor is damaged.
Power-on self-test normal, motor stops spinning during operation; indicator: yellow light for 0.5 s – off for 0.5 s, motor silent.	Motor is stalled/blocked and enters protection mode.	Check for foreign objects or mechanical binding; verify the motor rotates smoothly.
Power-on self-test normal, motor does not spin or stops mid-operation; indicator: yellow light for 1 s – off for 1 s, motor silent.	Short circuit or overcurrent protection occurs and the device enters protection state.	Open ESC cover; check for damaged motor wiring and loose wire/terminal connections.
During operation, the indicator light flashes red and green alternately.	PWM throttle signal is lost/missing.	Execute a safe landing; check PWM signal wire connection and cable condition.
During operation, the indicator light flashes yellow quickly every 0.2 seconds.	ESC detects the temperature is too high.	After landing and shutdown, check ESC case temperature; if overheated, check whether the 5 power terminal screws are loose.

Applications

Surveying and mapping
Aerial inspection
Professional aerial photography platforms
Facility safety and monitoring tasks

Details

The MAD 7X-10 integrated propulsion system combines an M7C10 motor, 60A 14S FOC ESC, and 26.2×8.5 propeller for use with 30mm carbon arm tubes.

The MAD M7C10 135KV disc motor uses a compact, layered rotor and stator design with a circular controller board for clean integration.

The carbon fiber composite folding propeller uses 26.2-inch blades and includes a red/green LED heading light for orientation.

The dimensioned drawing details overall span (665 mm), blade length (343 mm), and motor face diameter (81.5 mm) for fit checks.

MAD 7X10 KV135 specs list up to 8266g thrust per rotor at 48V, 12S LiPo support, a 26×8.5in prop, and a circular 60A FOC ESC with DroneCAN.

Benchmark data details throttle, thrust, RPM, and efficiency for the 7X-10 135KV propulsion combo on 12S with a FLUXER PRO 26.2×8.5 folding prop.
