Production aircraft were fitted with a 145 hp (108 kW) Warner Super Scarab radial engine.

With the company's involvement in producing trainer aircraft for the United States military, the S-C was not seriously marketed, and only 11 complete SCs (s/n 202 through 212) were built, all delivered in 1938; two more were later assembled from parts (s/n 213 in 1941 and s/n 214 in 1959).

This leading edge area was assembled as a single unit with major stresses, carried by the outer skin.

Thus the entire forward portion of the wing formed a light but strong tapered box spar.

A single perforated dural belly flap of split type, beneath the wing at a point about one-third back from the leading edge, was a new approach to the landing problem.
