What is the concept of Gyrocopter?
Gyrocopter is a relatively a very new terminology for me and my friends. These days, on some or the other way, we are hearing about it. But it is still difficult to understand this technology. Is it a type of helicopter? If yes, then how is it different? Are they going to replace helicopters soon? Is it faster than helicopter? What type of fuel is used for it? Who invented this technology and for what purpose?
