Graupner 4 x 3 CAM Speed Electric Prop

These are genuine Graupner CAM  propellers for use with electric or glow motors.They are strong and very reliable.The pitch and airfoil transition of all CAM propellors are computer optimised to give them the highest possible efficiency across the widest range of applications. Computer Aided Manufacturing allows them to be precision made to very tight tolerances. They are constructed of Carbon reinforced material to achieve maximum stiffness and to avoid torsional distortion of the thin high performance shape.They provide excellent thrust whilst maintaining low noise output and are produced to the usual high standards set by this German manufacturer.
