Helicopter replica takes to road

Yuan Jingying, a retired airplane engineer in Zhengzhou, Central China's Henan province, has spent five years to make a handmade replica of a helicopter, hoping to use it to send his grandson to school and bring his mother to travel around China.

The replica, named "China's Dream", is 12.5m in length and 2.8m in height. It can't fly but can travel on the road at up to 75 kilometers per hour.
