ESC Intelligent freewheeling technology, greatly improved performance. The innovative intelligent freewheeling technology enables higher driving efficiency and lower operating temperature of the ESC, and further improves the stability and reliability of the ESC. Powerful built-in BEC. The ESC has a built-in BEC with a continuous current of 5A and supports a maximum output current of up to 10A. The output voltages are switchable between 6V, 7.4V. This ensures that the ESC is able to support the demanding high-torque servos in the market. Efficient cooling system. The integrated radiator design, combined with the patented copper thermal conduction sink on the internal power board of the ESC, facilitates the rapid conduction of internal heat to the radiator, and the fan is added to dissipate heat. These results an efficient heat dissipation system to ensure that the ESC is always in a good heat dissipation state. Built-in capacitor. Super large built-in capacitor, The built-in capacitor of the ESC is as high as 1640uF. External capacitors are not needed for 10th scale models on the market and helps improves ease of use. High protection level, all-weather operation. The IP-67 waterproof Rating guarantees excellent waterproof and dustproof protection. The whole power system is able to drive on a variety of surfaces including mud, sand, ice, snow and water without damaging the power unit. Note: The IP67 protection level mentioned above is splash-resistant, water-resistant and dust-resistant under normal use, and splash, water and dust resistance are not permanently effective, and the level of protection may decline due to aging. Do not soak for a long time to avoid damaging the product.
