We believe in “genius” and we believe that Leonardo Da Vinci is the greatest inventor of all time who, thanks to his intuition, has managed to relate nature with man, creating countless inventions and projects for “machines” of all kinds, dedicating a lot of energy and time to those destined to achieve his dream: to make man fly!

For Meccanica Grezza, painting the flying machines of Leonardo Da Vinci on his quadrants is a tribute to the greatest of all genes, made with the help of his friend and painter Paolo Vermigli, a Tuscan like Leonardo who, with the use of hands and of his own pictorial and expressive ability, he fixed the vision and the dream of Leonardo on the quadrants of the model MG01 44S.
