The aircraft was a design of Lee Wainscott and appeared during the 1930s and the construction was started by a gentleman named Case. Initial plans called for the use of a (modified) Heath Henderson motorcycle engine, but by the time the aircraft was completed a 35hp Lawrence radial was installed. The aircraft was rumoured to have a movable (pivoting) lower wing for the lateral control thus eliminating the need of ailerons.

For several reasons the aircraft never flew prior to WW II and it was later acquired by brothers P.E (Pat) and R.L. Day who made several modifications (the lower wing became fixed and ailerons were added to the upper wing) and also installed a 65 hp Lycoming O-145-B2 engine. The aircraft finally first flew during 1962, registered N72L, and in 1969 it was sold to Howard C. Cagle. It was reported that the aircraft flew no more than 5 times in total and then went into storage.

Over the years this extremely small aircraft was reported under various names including Case Special and Wainscott Li’l Twister.
