Westland Lynx

Now something about the fastest helicopter of the world. Westland Lynx is a British multi-purpose military helicopter designed and built by Westland Helicopters at its factory in Yeovil. Originally intended as a utility craft for both civil and naval usage, military interest led to the development of both battlefield and naval variants. The Lynx went into operational usage in 1977 and was later adopted by the armed forces of over a dozen nations, primarily serving in the battlefield utility, anti-armour, search and rescue and anti-submarine warfare roles. In 1986 a specially modified Lynx set the current Fédération Aéronautique Internationale's official airspeed record for helicopters. In 1972, a Lynx broke the world speed record over 15 and 25 km by flying at 321.74 km/h (199.92 mph). It also set a new 100 km closed circuit record shortly afterwards, flying at 318.504 km/h (197.91 mph).

Looks really light, doesn't it?
