KO PROPO is a brand of radio control equipment and humanoid robot (KHR-1) by Kondo Kagaku, established in Tokyo, Japan in 1945. In 1982 KO PROPO introduced the Expert EX-1, reported to have been the first to integrate a pistol grip into a transmitter device with a gun trigger to act as the throttle, which later became a popular fixture in radio controlled transmitters.
