Kokkola KO-04 Super Upstart
In 1968 the Kokkola Brothers, Kalevi and Seppo, designed the KO-04 Super Upstart autogiro or gyrocopter with rotor-tip thrusters for increased take-off performance. The plane was registered OH-XYY (Serial number 1) during 1969 – 1976, and after that it came in airworthy condition to the Finnish Aviation Museum. The plane was donated to the museum’s collection in the end of the 1990’s.
