Zdarsky started the company after carving his own propeller for a homebuilt ultralight trike that he flew to escape from Cold War Czechoslovakia, over the Iron Curtain to Vienna in 1984. Ivoprop has sold more than 20,000 propellers since then.

The company's propellers are built from carbon-fiber-reinforced polymer and feature a stainless steel leading edge.
