Lester J. Bannick developed the Bannick Model T Copter (N9989Z) in 1964. This was a simple 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 for home construction. 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. No further details of development are known and it is believed that the Model C was eventually abandoned.
