The Soviets were somewhat stuck. They had a very small aero industry before 1917 and then it collapsed. Many of the best and brightest fled the country either at the time or in several years of civil war that followed. The Soviet leadership wanted to modernize and the fastest way to do that was to import foreign technology will the domestic workers/engineers were educated/gained experience. Trouble was that some of the technology was constrained by what countries would deal with them and when (although the did wind up buying quite a few designs).
As an aside, the story of the Soviet industrialization is really something. Amtorg boss Saul Bron and American industrial architect Albert Kahn setup training for thousands of Soviet engineers and designers, and oversaw building of hundreds of plants and factories. Magnitogorsk, a massively huge steel works that AFAIK still is one of the larger ones on the planet. Modeled after the US Steel corporation plant in Gary, Indiana. The Stalingrad tractor works, that produced a zillion T-34 tanks during WWII? A carbon copy of the International Harvester plant in Milwaukee. Etc etc., designed together with Americans, often trickier parts/machines sourced from the US and the rest locally.
And what happened to Saul Bron after all this massive contribution to the industrialization of his country? Well, having dealt with those Americans so much he was considered potentially dangerous and corrupted by their pesky capitalist logic, so he was executed during one of Stalin's purges.
