Pitts Model 11 Super Stinker
In 1991 Curtis and a group of friends formed a new company, Aero Design Eleven, and he designed the Model 11-260. A single seat Lycoming powered aerobatic biplane incorporating all that has been learned including his "Aerodynamically Boosted Ailerons." Construction of the model 11 then began.
In 1993 the prototype model 11 was completed by Curtis Pitts, Pat Ledford, Don Lovern, Bill Lancaster and Will Teft. The new airplane was dubbed "Super Stinker" in the tradition of many of the prototype designs Curtis created through the years.
