The scientific genius of Leonardo da Vinci is brought to life in this easy to assemble snap-together plastic flying machine. Taken from the pages of da VinciÂs priceless and awe-inspiring notebooks this model is made of plastic and requires no special tools. The manual is very educational and teach how these inventions have evolved into what they are today. The genius Da Vinci drew inspiration for his work from his direct observation of the flight of a bird. Da Vinci described its dimensions the materials with which it is to be built and its shape and how it works the whole notebook revolves precisely around the construction and use of the machine. Da Vinci also imparted some Âflying lessons on how the pilot should operate the machine. The piloting must have been complex. He would use his hands and feet to activate ropes and could rotate move and open and close the wings with his own movements. Da VinciÂs design is not drawn in its entirety. We must therefore reconstruct the indispensable parts. These include: the canvas to cover the wings some articulations and pulleys and the tail which Da Vinci knew was indispensable for controlling the machine.
