Hartzell Propeller has unveiled a new lightweight carbon fiber constant speed prop specifically designed for Rotax 916 powered aircraft, it announced Tuesday.
CubCrafters’ Carbon Cub UL is the first aircraft to feature the Kestrel prop which, according to the company, is expected to be a popular upgrade from fixed or ground-adjustable propellers.
“The Kestrel marks the first next-generation propeller for Rotax 916 engines, combining lightweight composite design with high performance aerodynamics,” JJ Frigge, Hartzell Propeller president, said in a statement. “It is tailored for the excellent backcountry and cross-country flying capabilities of the STOL Carbon Cub UL."
The Kestrel is the first prop in the company's new Falcon composite series for Rotax engines. It weighs 19.6 pounds—10 pounds lighter than other options—making it the lightest constant speed propeller available for Rotax 916 engines, the company said.
The three-blade, 76-inch prop "delivers aerodynamic efficiency and strength without adding unnecessary weight," the company said.
The Kestrel has received ASTM approval, and Hartzell said it expects FAA certification later this year.
