Young Chinese Farmer Builds Home Made Helicopter
20 year old Wu Zhongyuan–a farmer from the Henan province–created a home made helicopter using wood from an elm tree, a 150 cc motorcycle engine, steel pipes and no formal training–except for what he learned in a middle school physics class.
In Guangdong, 12-year old Xie Yanshou has created a flying car capable of taking off vertically.
“The car is powered by two pairs of propellers of the same rotation speed and different rotation direction, which would also balance the propellers’ torsional stress at the same time. Ducted fans are another feature helping accelerate the efficiency of the propellers and protect people from getting hurt.” said Xie
