GT-Propellers has introduced “low inertia” wood/carbon blades specifically designed to be installed on existing Hartzell Propellers. The experimental blades are compatible with Hartzell props, according to officials with the Italy-based company.
Interested owners can buy the GT blades (you must specify engine type, aircraft type and Hartzell hub type) and take them to their local prop shop for installation. The new blades use the same hub and internal items as the existing Hartzell prop, company officials said, noting no engine modification is required.
Two blade models are available: V-19 paddle for aerobatic planes,V-14 for tourer planes.
