Graupner G-Sonic computer designed model airplane props

Graupner G-Sonic props are manufactured on ultra-modern CAD/CAM (Computer-Aided-Manufacturing) machines and provide true running and tracking to the highest degree. Specially calculated airfoil sections for each propeller guarantee the best possible aerodynamic efficiency. Increase the performance of your airplane while reducing the noise generated by the prop. Made from ultra-high tensile strength plastic for great torsional rigidity. All propellers in this series have an 8mm center bore. Suitable for use on glow or electric powered airplanes. Available in sizes ranging from 11x6 to 22x12.
