Product overview
The CKESC FLY 80A 18S from Nanchang ChangKong Technology Co., Ltd. is a brushless motor electronic speed controller for UAV propulsion integration. Its 88.4 × 36 × 16.7mm body weighs 97g including wiring. The wiring configuration comprises power leads, three-phase motor leads, a shielded signal cable and a separate data feedback cable. Optically isolated signal inputs and outputs provide interference isolation, while serial telemetry reports supply voltage, motor speed, current, controller temperature and debugging data.
The controller accepts 6~18S supplies and PWM control with 3.3~5V input signals. Its continuous operating current is 40A with specified heat dissipation; the 80A maximum applies for three seconds. Standard ingress protection is IP54, with IP67 available by customization. Low-voltage protection is disabled by default and can be enabled through customization. Above 115°C, thermal protection progressively reduces available power, potentially to 40% of full-throttle power, before restoring it as temperature falls. Stall protection attempts a restart, but a stall at high throttle may damage the controller.

| Overcurrent protection | Limits peak current to prevent it exceeding the limit |
| Overload protection | Limits maximum throttle to protect the propulsion systemWhen excessive motor load is detected. |
| Signal-loss protection | Progressively reduces output power, rapidly lowers throttle below 50% within 1~2 seconds, then slowly reduces throttle until shutdownAfter signal loss lasting 200ms. |
| Serial telemetry | Real-time supply voltage, motor speed, current, ESC temperature and debugging data |
| Signal interface isolation | Optically isolated signal input and output interfaces |
| Signal cable shielding | Shielded signal cable to reduce interference |
