Radioplane OQ-6

In November 1944, Radioplane completed their model RP-14, which was evaluated by the USAAF as the OQ-6. The OQ-6 was more powerful than Radioplane's contemporary OQ-3, reaching a speed of 270 km/h (168 mph) with its 16 kW (22 hp) Righter O-45 four-cylinder engine. The model RP-15, first flown in January 1945 and most likely designated OQ-6A, had a 44 kW (60 hp) McCulloch O-90 engine, and could reach a speed of 313 km/h (195 mph).

Production orders for the OQ-6 were cancelled at the end of World War II, but a few OQ-6s remained in the USAF in 1948 for use as experimental target drones. As such they were designated XOQ-6A.
