The Kappa-7 was designed as a booster for Japan's later Kappa-8 and Kappa-9 rockets as well as being used as a single-stage sounding rocket. It was determined, however, that the vehicle was unsuitable as a single-stage rocket. The lone Kappa-7 flight was made on November 18, 1959 to confirm the motor's suitability as a booster. 

ASP's model of one of Japan's early sounding rockets makes a great beginner's kit. Capable of flying on a wide range of engines, this great looking and great flying model can be flown on practically any size field.
