Leonardo may be the first European to be interested in solving flight problems, including designing a large number of mechanical devices such as parachutes and studying the flight dynamics of birds; about 1485 he proposed a human-powered flying machine, which is to use a mechanical model to Imitate the movement and structure of a bird, like a bird, using flapping wings for propulsion. Such human-powered flying mechanical devices based on birds or bats have been constantly being retrospected in the next four centuries. https://5993.cyberbiz.tw/s/files/5993/ckeditor/pictures/content_7b2198f1-e9f0-4e4a-9d4a-f12cd334fc53.jpg ▲Turn the clockwork, the wings will really swing like a big bird. https://5993.cyberbiz.tw/s/files/5993/ckeditor/pictures/content_12b05029-4185-4308-b6fc-6f9c4c44f745.jpg https://5993.cyberbiz.tw/s/files/5993/ckeditor/pictures/content_f75c8b26-324e-4509-9a1b-7b32a9986402.jpg https://5993.cyberbiz.tw/s/files/5993/ckeditor/pictures/content_39566596-fa67-48a7-a009-83141fe4a41a.jpg Product size: 5 x 2.5 x 9.8 inches Precautions: ► The assembly can be completed without battery, coloring, and glue. ► Be careful of children swallowing small parts. ► This product is suitable for use over 14 years old. ► Please note that the appreciation period is not equal to the trial, if there is assembly, it will affect your return rights.
