AH_7657314f-0872-11ed-9ba8-ac1f6b742a2bBiplanes were very popular in the early days of aircraft construction, when the Wright brothers launched the first ever human-powered aircraft with a motor. Biplanes have two fixed wings positioned one above the other and connected by support struts, which allows them to achieve high lift even with insufficient strength. But despite all the advantages of this design, due to the development of technology, biplanes have practically become a thing of the past.The wooden 3D construction set allows you to return to the era of aviation birth and feel like one of the first aircraft designers. The model can move without batteries and has an open design so that you can see how each part works.The mechanical 3D puzzle has a rotating propeller and works thanks to a rubber motor: you assemble it without glue or additional tools, place it on a surface, pull it back to start it, and then release it and watch it move.
