For different motors, it can be divided into brushed ESC and brushless ESC. Due to the limitations of brushed motors, brushless motors are now commonly used, so they are equipped with ESC for brushless ESC. Therefore, the brushless motor is equipped with a brushless ESC, and the brush motor is equipped with a brush ESC. The function of the ESC is to convert the control signal of the flight control board into the magnitude of the current to control the speed of the motor and complete the specified speed and action. Because the current of the motor is very large, if there is no ESC, the flight control board can not withstand such a large current, nor does it drive the function of the brushless motor. At the same time, the ESC also acts as a voltage variator in the four axes, and the voltage of 11.1v is changed to 5v to supply power to the flight control board and the remote controller. The number of A will be marked by the ESC, such as 20A, 40A: This number is the current that the ESC can provide. The high current ESC is compatible with small currents. Small current ESC cannot be used beyond the standard. ESC has the difference between fast response and slow response. Because four-axis flight requires a quick response to ESC, the four-axis requires a fast-responding ESC. In fact, most common ESCs can be programmed (the ESC has a lot of function modes, this function is to program the ESC), and the response speed can be set by programming. The programming method can directly connect the ESC to the throttle output channel of the remote control receiver (usually 3 channels). According to the manual, the joystick can be set by moving the joystick, or it can be set by the manufacturer's programming card. This needs to be purchased separately), the method is simple, no need to connect the remote control. In order to be insured, it is necessary to set the ESC to be consistent, otherwise it will be difficult to control. Also, be sure to read the instructions! Finally, the friendship reminder: Many brands of ESC are not enough power and current, maybe you need 60A ESC, it can only go up to 55A, you can't go up again, so you must ask the supplier when choosing ESC. Whether it is enough power. PS: The principle knowledge of ESC can be related to the forum. For me, I can only read the manual.
Mini Circuit breakers, also named as the air switch which have a short for arc extinguishing device. It is a switch role, and also is a automatic protection of low-voltage electrical distribution. Its role is equivalent to the combination of switch. Fuse. Thermal Relay and other electrical components. It mainly used for short circuit and overload protection. Generally, According to the poles, mini Circuit breaker can be divided into 1P , 1P+N , 2P, 3P and 4P.

The ESC is called "Electronic Governor". The most important applications are the model of airplane, car model, ship model and so on. At present, there are also RC airplanes specially designed for aircraft models, car models and ESCs designed for car models.
