The company's headquarters are in Long Beach, California.[1][2] Zdarsky started the company after carving his own propeller for a homebuilt ultralight trike that he flew from Cold War Czechoslovakia, over the Iron Curtain to Vienna in 1984. Ivoprop has sold more than 20,000 propellers since then.[1][2] The company's propellers are built from carbon-fiber-reinforced polymer and feature a stainless steel leading edge.[1][2] Ivoprop variable-pitch propellerIvoprop produce both in-flight adjustable and ground-adjustable propellers of unusual design. Whereas conventional variable-pitch propellers rotate at the blade root, the Ivoprop design has its blade fixed. The blade is hollow, containing a steel torsion rod fixed to the blade tip. By mechanically turning the rod within the hub, a twist is achieved which adjusts the blade's angle of attack.[3] See also
