This aircraft was initially equipped with a Duc Swirl 3 propeller, then an E-Props Durandal-3 was installed, which had already significantly increased performance and reduced weight.
The weight of the propeller does not increase the propeller’s efficiency, but it does increase the efficiency of the whole aircraft.
The installation of the Glorieuse propeller on the FK12 represents a further improvement in performance.
