Radioplane OQ-14 Beginning in the 1930s, the United States used radio-controlled model airplanes as aerial targets for antiaircraft gunnery training. Starting in 1935, the Radioplane Co. in California developed several variations of an original design by former movie star and modeler Reginald Denny. Powered by a 20-hp Righter engine to a top speed of 140 mph, the Radioplane OQ-14 served as an aerial target in the years after World War II. Launched from a catapult, it landed by parachute. By 1954, improved models superseded the OQ-14, making it obsolete. This aircraft can be found hanging in Building 2's Korean War Gallery. Click here to return to the Korean War Gallery.
