German model enthusiasts make Boeing 747 passenger aircraft model can fly to heaven

Before the Airbus A380, the Boeing 747 was the largest aircraft in the civil aviation industry. Since its inception in 1970, the Boeing 747 has maintained the world's highest passenger load record for 37 years before the Airbus A380 is put into service.

Because the shape is very distinctive, Boeing 747 is known as the "air queen" and attracts many fans. Recently, even German model enthusiasts spent more than 2,000 hours making a model of a Boeing 747-400 passenger plane, and actually can fly.

Unlike ordinary airplanes that use electric propellers to drive, the Boeing 747 model is equipped with four jet engines, each weighing more than 14 kilograms.
