• Description


The G-SONIC PRO series of propellers was developed from the proven G-SONIC series of propellers. The proven blade shape has been adopted and greater torsion, bending and tensile strength has been achieved by using high-strength, modern plastic. This makes the GRAUPNER SONIC PRO propeller series even more efficient and generates more thrust at a lower volume. The Graupner G-SONIC PRO propellers are designed and manufactured using the latest CAD/CAM systems and machines. Thanks to this precise design and manufacturing method, the propellers achieve optimum tracking and concentricity.
