125pcs 3D Metal Mechanical Helicopter Model Building Kit- Lifting Spirit ? PROTOTYPE HISTORY At the beginning of the 1900 century, Igor Sikorsky, a Ukrainian schoolboy from Kiev, saw a drawing of a flying machine having a Leonardo da Vinci propeller, and this gave spawned dreams of a manipulated flight in his head. When he was 19 years old and a student at the Kiev Polytechnic University, Sikorsky designed several aircraft models, including a helicopter. Sikorsky's first rotary-wing aircraft stayed on the ground, and for several years his focus was on airplanes. It was after 20 years that the engineer returned to helicopters. The machines were constructed in the USA and turned out to be the ancestors of the world's most successful model series. Advantageous of their capability to fly at low heights, lift off and land on small flat areas, and hang in the air, helicopters have turned out to be the primary type of supplementary aircraft - rescuers, carriers of goods, and people in remote areas, personal transport, and flying cranes ?FEATURES, BENEFITS Advantageous of their capability to fly at low heights, lift off and land on small flat areas, and hang in the air, helicopters have turned out to be the primary type of supplementary aircraft - rescuers, carriers of goods, and people in remote areas, personal transport, and flying cranes. ?
