The C-1 was a wire-braced high-wing monoplane with a fixed tail skid landing gear and powered by a 360NaN0 Aeronca E-113 flat-twin piston engine. Apart from a more powerful engine the C-1 also had a strengthened fuselage and reduced span wings compared with the C-2. Only three were built and following the death of a company executive when the prototype crashed, one was scrapped and the other was converted into an Aeronca C-2N.
