Gyrodyne RON Rotorcycle
The XRON-I Rotorcycle or YRON-I Rotorcycle (originally designated HOG) was a tiny, single-seat helicopter designed under contract for the U.S. Navy.〔 in the mid-1950s. It later was designed for a United States Marine Corps requirement for a small personal helicopter that would fulfill a number of roles, including observation, liaison, small unit tactical maneuvers, and which could be dropped to downed airmen behind enemy lines to facilitate their escape.
==Development==
Gyrodyne purchased the assets of Bendix Helicopters in 1949, including the Model 2C coaxial helicopter which provided the technology for the XRON-I. In 1951 the Model 2C was demonstrated to the Navy with shortcomings noted in autorotation control. The XRON-I was demonstrated under a new Navy contract NOas 55-388-c for a lightweight single man helicopter.
