Glider designed by Arzeulov in 1921, built with the help of his friends in the gliding club of the Military Academy of the Air Force.
The first tests took place during winter 1922-1923, towing it behind a sled, but due to snow and uneven terrain, the aircraft did not take off.
The following summer, July 24, 1923, A-5 was successfully tested on Khodynka airport (Moscow), towed behind a car. The glider ascended to the height of 15 m, then flow perfectly controlled.
In the first contest of Theodosia, Crimea, 1923, A-5 received the grand prize and made a record with a flight duration of 1 hour 2 minutes 30 seconds.
Then, in 1924, another A-5 was built, either identical or slightly modified from the first aircraft. In the second contest of the Crimea in 1924 it was able to beat the gliders "Icarus" (Икар), "Ilich" (илъич), "Pioneer-Leninist" (Пионер-Ленинец) and "Red Student" (Красный студент).
