main features Use powerful and high performance MCU. Users can configure the functions as their demand, fully embody Intelligent features. Unique circuit design, strong anti-interference. water resistant design (Note: if there is water at CES, please dry the water in the connectors). Start mode can be configured. the quick accelerator response, and has very good linear speed control. Compatible with boat scale and racing boat. Low voltage protection threshold value can be adjusted. Built-in BEC switch, large power load with servo, low power dissipation. multiple protection functions: abnormal voltage protection / low voltage cutout protection, excess thermal protection and protection against accelerator signal loss, making the CES more reliable. High-performance safety performance: As long as the throttle lever is, the engine does not start immediately. on thermal protection: when ESC temperature is above 100 degrees Fahrenheit, output power is automatically reduced. When it is less than 80 degrees Fahrenheit output power will return to normal.menu adjustment cycle, simple operation. support adjustment with program box and transmitter.
