Mini-BiplaneMini Biplane The Wright brothers got it right. When these talented bicycle mechanics set out to build the world's first motor driven, heavier than air airplane, they needed wings that could provide enough lift, yet be light and strong. They went with a biplane design, seen in early hang gliders. Biplanes have two fixed wings, one on top of the other, connected with supporting struts; the bracing permits a lighter wing structure.
