The Warren CP-2, also called the Warren Taperwing, or the Kinner Taperwing was the third and last aircraft built by engineering students at California Polytechnic College in the 1930s[1] The aircraft is a side-by-side open cockpit biplane with conventional landing gear, powered by a Kinner K-5 radial engine.
The wings used wooden spars and ribs with fabric covering.
The fuselage was acquired from the liquidation of Arrow Aircraft in Lincoln, Nebraska.
[1] The aircraft was registered in the experimental category and several attempts were made to register it in the restricted category for aerial photography.
[1] New owner Clifford Bryant flew the aircraft from Fresno, California until a partial motor mount failure caused the engine to nearly fall off in flight.
