Zimmerman Flying Pancake
 
Zimm-FlyPan
Wind tunnel testing (NACA)
 
The 1935 single place low-aspect-ratio "flying pancake" developed in off-times by Charles H Zimmerman, John McKellar, and Richard Noyes, then with NACA, for design competition with Ercoupe and Stearman- Hammond. US patent #2,108,093 was issued to Zimmerman in 1938. Although rejected by NACA at too radical, despite its potential as a stall-proof airplane, elements of the design surfaced later in Vought V-173 and Vought-Sikorsky XF5U-1.
 
Unable to synchronize the motors, rather than risk an accident the project was abandoned and it never flew.
