A new series of propellers from Graupner designed specifically for electric powered aeroplanes and multi-rotor 'copters. For the 8,9,10,11,12 and 14" size propellers in this range, there is an exact same size propeller for rotation in the opposite direction. These propellers are therefore ideal for counter-rotating setups.
Graupner Elektro propellers are light-weight and have a low resistance profile. They are produced from carbon reinforced plastic, providing excellent torsional strength.
