Product overview
The CKESC STONE 80A-MC from Nanchang Changkong Technology is a brushless electronic speed controller for UAV propulsion integration. Its architecture combines power leads, three motor-phase leads, a shielded signal cable and a separate data feedback cable. The controller measures 90.4 × 36 × 18.5mm and weighs 112g including wiring, defining its installation space and mass contribution. PWM control accepts 3.3–5V signal levels, while optically isolated signal input/output interfaces provide interference isolation. Serial telemetry provides supply voltage, motor speed, current, ESC temperature and debugging data.
The electrical specification is 80A and 6–14S, with continuous operation specified separately at 50A under particular heat-dissipation conditions and a 100A maximum lasting three seconds. Standard ingress protection is IP54, with IP67 available by customization, and there is no BEC. Low-voltage protection is disabled by default. Overtemperature protection progressively reduces available power above 125°C, while signal loss triggers a staged throttle reduction to shutdown. Stall protection attempts a restart, but a stall at high throttle can damage the controller. Rotation direction is software configurable.

| Overtemperature protection | Maximum output power gradually decreases, potentially to 40% of full-throttle power.Temperature above 125°C; original power restored after cooling. |
| Signal-loss protection | Output power progressively decreases; throttle falls below 50% within 1–2 seconds, then decreases slowly until shutdown.Signal lost for 200ms. |
| Low-voltage protection | Customizable low-voltage protectionDisabled by default; enabling requires customization. |
| High-voltage protection | Motor startup is inhibited.Supply voltage exceeds the permitted value. |
| Startup protection | Starting current is limited and startup is retried automatically.Motor startup is unsuccessful. |
| Stall protection | Attempts to restart the motor.Motor stalls during normal operation; a stall at high throttle may damage the ESC. |
| Overcurrent protection | Limits peak current to prevent it exceeding the limit. |
| Overload protection | Limits maximum throttle to protect the propulsion system.An excessive motor load is detected. |
| Real-time telemetry | Supply voltage, motor speed, current, ESC temperature and debugging dataVia serial output. |
| Signal interference isolation | Shielded signal cable and optically isolated signal input/output interfaces |
| Motor rotation direction | Software configurableConfigured through software. |
| Firmware configuration | Timing-adjustment debugging firmware by default, optional fixed firmware, and an enableable maximum-power modeDefault firmware is the timing-adjustment debugging version; a fixed version is optional. |
