The earlier versions of the type are not well recorded but all had high wings with rectangular inner panels, tapered outer panels and pairs of single external bracing struts. They lacked the gull wing which characterized later Spalinger designs; this only appeared in 1934 with the aerobatic S.15K. Many of its features were maintained in his later aircraft. The S.15K has a single spar wing, with central, internal diagonal drag struts. In front of the spar and struts the wing is plywood-covered, forming torsion resistant D-boxes.

WikiProject Aircraft
A WikiProject, or Wikiproject, is a Wikimedia movement affinity group for contributors with shared goals. WikiProjects are prevalent within the largest wiki, Wikipedia, and exist to varying degrees within sister projects such as Wiktionary, Wikiquote, Wikidata, and Wikisource. They also exist in different languages, and translation of articles is a form of their collaboration. During the COVID-19 pandemic, CBS News noted the role of Wikipedia's WikiProject Medicine in maintaining the accuracy of articles related to the disease. Another WikiProject that has drawn attention is WikiProject Women Scientists, which was profiled by '' Smithsonian'' for its efforts to improve coverage of women scientists which the profile noted had "helped increase the number of female scientists on Wikipedia from around 1,600 to over 5,000". On Wikipedia Some Wikipedia WikiProjects are substantial enough to engage in cooperative activities with outside organizations relevant to the field at issue. For e ...
