The electric adjustment is the electronic governor. The function is to convert the voltage input from the battery into 5V output to the servo, flight control, receiver, etc., and the other function is to obtain the throttle signal from the receiver to control the speed of the motor.   The ESC is divided into brushed ESC and brushless ESC. Brushed ESC is the device that controls the brush motor. Brushless ESC is the device that controls the brushless motor. Brushed ESC generally has four lines and two. The strip is connected to the positive and negative poles of the power...

The motor, also known as the motor, is one of the devices that power the aircraft. The motor is divided into a brush motor and a brushless motor. The brush motor refers to a motor with a carbon brush. The function of the carbon brush is to reverse the direction. Brushless motor refers to a motor without a carbon brush. The controller provides different current directions of DC to achieve alternating current direction of the coil inside the motor. Any two motors and ESC wiring can be exchanged to change the steering of the motor. The part that rotates when...

1, divided by takeoff weight

The Civil Aviation Administration flight standard officially issued the "Light and Small UAV Operation Regulations (Trial)" (hereinafter referred to as the "Regulations"), which is regarded as the first "traffic regulations" in the field of drones. According to the "Regulations", the drones will be in accordance with the weight. For classification management, the four cities of Beishangguangshen and Shenzhen will become the leading areas for UAV supervision. The “Regulations” classify civil UAVs into seven categories: the weight of the aircraft and the take-off weight of less than 1.5 kg for Class I unmanned Machines; Class II drones with an empty weight between 1.5 and 4 kg and a total take-off weight between 1.5 and 7 kg; the weight of the empty machine is between 4 and 15 kg, and the total weight of the takeoff is between Class III drones between 7 and 25 kg; Class IV drones with an air weight between 15 and 116 kg and a total take-off weight between 25 and 150 kg; plant protection drones Class V drones; unmanned airships are Class VI drones; Type I and II drones that can run beyond 100 meters away are Class VII drones. Among them, Class I drones only need to be used. People ensure safety and are not subject to the “Operation Regulations”

2, by purpose

According to the purpose, the drone can be divided into three levels: military, industrial and consumer.

Consumer-grade drones are the most well-known types of the public. These types of drones are generally gyroplanes, which are small in size, endurance and flight distance are very limited, and the price ranges from several thousand to several tens of thousands, mainly for entertainment and aerial photography.

Industrial grade - UAVs have higher technical thresholds than consumer drones. In order to meet the needs of the industry, the drone is required to have longer endurance, longer flight distance, greater mission load, and more reliable safety.

Military-level drones are high-tech weapons that serve the war. All technical requirements are strict.

Warning: This is indoor copter, Can’t be flying outdoor when there is wind!Can’t be flying too high to affect the sight!  It is necessary to go to a place with a large space to play it (Especially the novice must pay attention)!  If the Copter collides with items such as walls, you must timely lower the throttle! Otherwise ESCs and motors may be burned, and battery may be burned or exploded. About the Li-po Battery: 1s=3.7v is the best retention voltage for the copter’s battery. After fully charged, it is about 4.2v. The battery voltage is below 3.5v for over-discharge. 2s=7.4v. After fully...
