Graupner 22 x 6 G-Sonic Pro Propeller

This is a Graupner G Sonic Pro propeller. The proven blade design features high resistance modern plastic and has led to an increase in torsional strength, bending strength and tensile strength. This has made the Graupner Sonic Pro series propellers even more efficient as they are able to generate more thrust at reduced noise levels.

Graupner G-Sonic propellers are designed and manufactured 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.
