This aircraft paper model is an Udet U 12 Flamingo, an aerobatic sports plane and trainer aircraft developed in Germany in the mid-1920s, the papercraft is created by Piotr. There are 1:50 and 1:33 two scale versions available.
The U 12 was a conventional, single-bay biplane of wooden construction with the wings braced by large I-struts. The pilot and instructor or passenger sat in tandem, open cockpits. The U 12 proved extremely popular and sold well, due in no small part to Ernst Udet's spectacular aerobatics routines while flying the aircraft. One particularly acclaimed part of his act included swooping down towards the airfield and picking up a handkerchief with the tip of one wing.
