Aeronca Sedans have all-aluminum wings (and spars) and fabric/steel
frame fuselages and control surfaces. Cessna went the opposite way
with the competitive C-170 although both used the same 6 cyl 145 Hp
Continental engine. The Sedans were slower. A lot of them were put on
floats and retrofitted with 180 Hp Lycomings.

I rebuilt & flew 1/4 of one on floats with the Continental 38 years
ago. It was a lot of fun, but it gave my wife a headache riding in it
- as soon as we got engaged.
