An unmanned reconnaissance plane of four rotation wings is provided to overcome an existing plane of two wings which can be fallen by damaging one of two wings and is weak against side wind. An unmanned reconnaissance plane of four rotation wings comprises the following units. An unmanned helicopter of a round shape and an automatic sensor are mounted in a motor(2). The unmanned helicopter and the automatic sensor minimize wind resistance. The four motors are respectively operated so that taking off/landing, forward/backward movement and left/right movement of the unmanned helicopter are possible.
