The new generation of folding propellers from Rudolf Freudenthaler, exploiting CAM technology. The very thin, carefully optimised blade profile and computer-calculated airfoil sections guarantee very high accuracy and excellent efficiency combined with low power absorption from the electric motor. CAM carbon folding propellers have been the standard in electric flight for many years. The new Z propellers have been specially optimized for even tighter folding on narrow glider fuselages.
