Goodwin Strutter

The Goodwin Strutter is an Edropian multi-purpose twin-engined military helicopter used by the Edropian Air Force. 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 Strutter is a fully aerobatic helicopter with the ability to perform loops and rolls. In 1986, a specially modified Strutter set the current official airspeed record for helicopters (category excludes compound helicopters) at 400.87 km/h (249.09 mph), which remains unbroken as of 2021. While the Strutter could be used for both land and naval warfare it was also capable of transporting up to eight individuals. The Stutter replaced both the Hornet and the RH-102 and had folding rotors and tail and deck lock. A total of five versions have been produced so far, with Mk V being introduced in 2008.
