Bensen B-8M Gyro-Copter

A helicopter-airplane hybrid, the single-seat Bensen B-8M Gyro-Copter is an experimental homebuilt aircraft designed by Igor Bensen in 1955. Generally considered to be one of the safest and easiest light aircraft to operate, the popular Gyro-Copter was designed to be constructed from pre-fabricated kits or a simple set of plans. The rotor of the Gyro-Copter is not powered, but rotates and generates lift from the airflow created by the forward motion of the aircraft.

The Museum's Bensen B-8M Gyro-Copter is currently undergoing restoration at the Museum's Restoration Center at Paine Field.
