With the manufacturing process they have, all the blades of the same size are made in the same mold. This keeps the weight difference between the various individual blades of the same type to be almost negligible. This, together with the 4-blade design, results in an extremely well-balanced propeller, which most metal propellers have difficulties to demonstrate. All the props are adjustable to different pitches, and the blades are replaceable in case of damage. The parts are molded in a fiberglass-reinforced polyamide, which is an accepted substitute for cast metal, mainly aluminum.
