Lester J. Bannick developed the Bannick Model T Copter (N9989Z) in 1964. An open-frame gyrocopter, similar to the Bensen Gyrocopter with a wooden rotor and a pusher 65hp Lycoming engine, it was marketed in the form of plans ($25) for home construction, at about $600.
The only welding is in the motor mount, only machining is in the rotor head, the remainder of construction is with hand tools.
Bannick then completed the prototype of the Bannick Model C Copter which flew in 1967. It used the rotor system of the Model T with a streamlined glass-fibre fuselage incorporating a large tail fin and a 135hp Lycoming engine. It is believed that the Model C was eventually abandoned.
