The progress has been made towards of unmanned aircraft development increasing rapidly and usefull. Monitoring of hazardous areas, fertilizer sowing in paddy fields, the spread of insecticides in rice fields can be easily implemented and fast. Multirotor drones have agility maneuvers. The maneuver is produced by a fast spinning of propeller motion. If one of the propellers is interrupted, the planes flight becomes unstable. The stability of the UAV is a task of the flight controller. Flight controllers maintain stability on the basic of information received by the gyro sensor. But the flight controller never knows ESC conditions, flight controller always send commands only to the ESC . If the ESC is damaged, the flight controller doesnt to know. If this happens, the flight controller will give the ESC command to work optimally, and then the flight controller sees ESCs work on the report from the gyro sensor. Flight controller doesnt know ESC failed, or motor failed. In fact, for multirotor, this can result in a major accident. In addition, if the ESC performance is bad, the motor rotation also unstable too. For this reason, a motor failure sensor and ESC need to be built. The ESC failure sensor design involved 3 current sensors and an ESC control signal from the flight controller. The inconsistency between the instructions from the flight controller and the outflow will be reported in the form of a hazard warning after being processed by the microcontroller. This output can be followed up to be fed to the flight controller or flash light or sound warning, depending on the configurator. In the design of this safety system, the program algorithm for making decisions on the microcontroller involves the amount of current, the duration of the current flow, the amount of peak current and the time of control entering ESC.
