No wonder they have won fans around the world. DUC props can be found in a wide number of countries, attesting to their strong function in a variety of climates and conditions.

Range or Products — DUC offers three-blade props in several configurations such as Flash and Flash-2, Swirl, and Windspoon plus a five-blade series called Flair (find all prop details here).

In my experience, pilot love learning about engines. Yet without a prop, that engine may run fine, but nothing happens to the airplane other than converting a tank of fuel into noise.
