Farmer’s home-made helicopter

A Chinese farmer with only a basic school education has made his own helicopter out of wood. Wu Zhongyuan, 20, of Luoyang, in central China’s Henan province, took nearly three months to complete his home-made aircraft. He says he used his memories of middle school physics lessons to make the machine which he claims can fly up to a height of 800 metres. “I didn’t have a design,” he said. “The only source for me to get relevant knowledge was surfing the internet via my mobile phone.” The blades are made from an elm tree, the engine is from a motorcycle and the frame is reinforced with steel pipes, reports Dahe Daily. ananova
