Rc 20A 30A 2-3S 1A/5V BEC Brushed ESC Speed Controller For RC Airplane Plane 370 380 390 280 270 Model Toys Eagle 20A/30A 2-3S 1A/5V BEC Brushed ESC Speed Controller Features: 1. Safety Arming Feature: Regardless the throttle stick position, the motor will not spin after battery connected. 2. Brake Settings: The brake function can be enabled or disabled by a jumper. 3. Battery Type: The battery type can be chosen by a jumper. 4. Low Voltage Protection Threshold: For lithium batteries, the threshold for each cell is 3.0V. When the battery\'s voltage is less then the threshold, the ESC will gradually reduce the output power to prevent the battery from over discharging. 5. Over-heat protection: When the temperature of the ESC is over 110 Celsius degree, the ESC will gradually reduce the output power. 6.Throttle signal loss protection: The ESC will gradually reduce the output power if the throttle signal is lost for 1 second, further loss for 2 seconds will cause its output to be completely cut-off. Advantages: Advanced microprocessor. Compatible with lithium battery and nickel battery. User programmable by using the jumper connectors.
