Kalinin and says do we want to start to design a fighter and what we stand for when we rightly should start the project of a fighter. We responded in full agreement.

In recent years, the aviation enthusiasts in many countries are showing great interest in flying on makeshift gliders-the gyros and the gyros. Inexpensive, easy to manufacture and easy to pilot, these aircraft can be used not only for sports but also as an excellent way to familiarize wide circles of young people with the element of air. Finally, they can be used for communication. In 1920 – 1940th years, gyros were built in many countries. Now they can be seen only in museums: they could not compete with helicopters. However, for sporting purposes the gyros and especially towed gyroplanes-gliders are used in our days (see figure).
For many years in his garden plot as a temporary shelter for the summer we built a wooden frame and pulled at his canvas tent.
