Feature: 1. FAST AND STABLE: The RC brushless ESC has a configurable start mode, fast throttle response, and support linear and fluent speed control, you can use with confidence 2. MULTIPLE PROTECTING FUNCTIONS: Brushless ESC is equipped with abnormal start protecting, overheat protecting, throttling signal loss protecting, and low pressure cut off protecting 3. HIGH POWER SAFETY PERFORMANCE: 30A brushless ESC is very safe to use, no matter where the throttle rod is located, the motor will not start immediately 4. TECHNICAL PARAMETERS: RC brushless ESC supports a variety of programming methods, remote control, programming. Input 3-4S LiPo, BEC output 5V 2A(switch mode) 5. EASY TO OPERATE: The ESC is easy to operate at home or on the fly, making it the first choice for knowledgeable model enthusiasts and RC enthusiasts alike Specification: Item Type: Brushless ESC Material: ABS Input: 3-4S LiPo Continuous Current: 30A Peak Current: 50A BEC Output: 5V 2A(switch mode) 1. Braking force When you move the throttle lever to the bottom position, the braking function will be activated. In this mode, the braking amount is equal to your preset braking force. 2. Voltage cut off type 2.1. Soft disconnect When this option is selected, ESC will gradually reduce the output to 60% of full power within 3 seconds after the low voltage cut off protecting is activated. 2.2. Hard cutting When this option is selected, ESC will cut off the output immediately when the low voltage cutoff protecting is activated. 3. LiPo battery If you select Calculate Automatically, ESC will automatically calculate the number of LiPo batteries you have inserted according to the 3.7V/Cell rule, or you can set this manually. Note: Only the following parameters can be selected for 15A and 20A: Automatic calculation, 2S, 3S. 4. Cut off the voltage If triggered, the low voltage protecting is disabled. In addition, the low voltage protecting function corresponding to the low, medium, three modes has a protecting voltage value of about 2.8V per segment, 3.0V per segment, 3.4V/cell. The value is the voltage of a single battery multiplied by the number of lithium batteries automatically identified by the electronic governor or manually set, i.e Battery protecting voltage.(For example, if the low voltage protecting threshold of 3 lithium batteries is medium, the protecting voltage of the battery is 3X3.0=9.0V) 5. Start the mode This is used to adjust the throttle response time for ESC acceleration from 0% to 100 percent. The normal, soft, very soft pairs should be about 200ms/500ms/800ms respectively6. Schedule The timing value of the drive motor can be adjusted. The low, medium, and high values are 5°, 15°, and 25° respectively. 7. Active Taxi (DEO) This item can be adjusted between Enable and Disable and is enabled by default. When enabled, you can get better throttle linearity or smoother throttle response. 8. Search patterns When this option is selected, ESC will drive the motor to beep when the throttle is held at 0% and continues until the set time.. Package List: 1 x ESC 1 x Programming Card 2 x Protective Case 1 x User Manual Note: The default throttle range of this ESC is 1100µs to 2000µs(double blades standard); when users start using a brushless ESC or other transmitters, throttle range calibration is needed.
