Claude Flagg and H. F. Landis built the aircraft in their spare time and patented the wing design.

The wings used an early application of lightweight aluminum construction with U-shaped cantilever spars with wire bracing and fabric covering.

In 1933 Wittman lengthened the fuselage by 21 inches, removed the engine cowling and modified the rudder.

An Air Commerce inspector fronted the money, and had Wittman race the aircraft to avoid a conflict of interest.

In 1936 the 200ci class is eliminated, making the Pobjoy Special obsolete for racing.
