In 1940, the U.S. Army Air Corps drew up a requirement for a radio-controlled target drone for training anti-aircraft artillery gunners. The first aircraft in a series of target drones was a modification of the Culver LFA Cadet which eventually led to the PQ-14 series used throughout World War II and beyond.
Docile and easy to fly, the aircraft was finished in a bright red target color scheme although operationally, a silver or red finish was applied. Without a pilot they were flown from a "mother ship" aircraft. The typical mother ship was a Beech C-45. Despite their short lifespan, the aircraft performed well and the Franklin engine was considered "trouble-free" .
Most of the Culver target aircraft were "blasted out of the sky" by Army anti-aircraft gunners but a dozen or more survived and were surplused after 1950. Flown as a recreational aircraft, their new owners found that the aircraft had a sprightly performance.
