After Tanks Encyclopedia, Naval Encyclopedia, and Plane-encyclopedia here is a new website dedicated to rotary wings aircraft, commonly called helicopters. An object of fascination since my first flight in an Alouette III back in 1980 in Africa, this type is just the near perfect flying machine if that was for speed and altitude concerns (both are linked !). I hope you’ll find any useful informations here. Not only about types and models worldwide, but also current manufacturers and news of the helicopter market.
