==Design== In January 1937, Aeronca unveiled the Model K, a replacement for the company's popular C-3. While it was powered by the same Aeronca E-113 two-cylinder engine as the C-3, the Model K Scout was of more conventional appearance, eliminating the C-3's distinctive fuselage "bathtub", replacing the wire-braced wings used by the earlier aircraft with strut-braced wings and providing a fully enclosed cockpit seating two side-by-side.{{sfn|Juptner|1978|p=123}}{{sfn|Simpson|2001|p=16}} The fuselage had a welded steel-tube structure with fabric covering, while the wings had spruce spars and spruce and plywood ribs, which were fabric covered. The aircraft had a fixed tailwheel undercarriage, where the wheels could be replaced with skis for winter operation, while there was also a floatplane version. Dual controls were fitted.{{sfn|Juptner|1978|p=125}}
Later in 1937, Aeronca unveiled a new version of the Model K powered by the 4-cylinder Continental A-40 engine, the Aeronca KC, while a similar version powered by the 4-cylinder Franklin 4AC-150 engine became the Aeronca CF.{{sfn|Juptner|1978|pp=193–194}} The availability of the more powerful Continental A-50 engine resulted in the Aeronca KCA. This was later developed into the slightly larger Aeronca 50 Chief.{{sfn|Juptner|1978|p=260}} Small numbers of 50 hp Model Ks powered by Menasco M-50 flat-four engines (the KM) and Franklin engines (the KF) were also built.{{sfn|Juptner|1978|pp=265, 301}}
A total of 357 Aeronca Model K Scouts were built.<ref>{{cite web|title=Aeronca K|url=http://www.aeronca.com/k/AeroncaK/stories/the_aeronca_k.htm|accessdate=30 October 2010|archiveurl=https://web.archive.org/web/20101206234634/http://www.aeronca.com/k/AeroncaK/stories/the_aeronca_k.htm|archivedate=6 December 2010|url-status=dead}}</ref>{{#tag:ref|Juptner states "350 or more" Model Ks,{{sfn|Juptner|1978|pp=125–126}} 35 KCs and 6 CFs,{{sfn|Juptner|1978|p=195}} "about 65" KCAs,{{sfn|Juptner|1978|pp=260, 262}} nine KMs,{{sfn|Juptner|1978|p=266}} and five KFs.{{sfn|Juptner|1978|p=302}}|group=lower-alpha}}
