In 1982 by the order of Ministry of Aircraft Industry the Design Bureau was transformed into a branch-wise experimental students aircraft construction design bureau of the MAI. The work was carried out by professional engineers. If necessary the co-workers from among the MAI students and teachers and also from among the workers of the industry were invited. The production facility of the MAI aircraft development plant (EOZ) in the experimental development shop (shop No. 3) are manned by qualified technicians. The OSKBES work on the experimental aircraft engineering constantly received high estimations of the industry. Their technical novelty and utility are confirmed by nine Introduction Certificates and more than twenty Invention Certificates. By the end of 1980s six experimental aircraft of different types were designed and built: Kvant, Elf-D UAV, PS-01 small-sized UAV, Elf, Photon and Yunior aircraft.
