The G-SONIC series of propellers have proven their selves as one of the best sports propellers made. The proven blade design and the use of high resistance modern plastic has led to an fantastic torsional strength, bending strength and tensile strength. This has made the GRAUPNER SONIC series more efficient as the propellers are able to generate more thrust at reduced noise levels.
Graupner G-SONIC propellers are designed and manufactured drawing on the very latest knowledge and using state-of-the-art CAD/CAM systems and machines. This precise approach to design and manufacture optimises the concentricity and blade tracking achieved by the propellers.
