The ADI Stallion is a US civil utility aircraft that first flew in July 1994. It is marketed in kit form for homebuilding by Aircraft Designs Inc. Design and development The Stallion is a single-engined high-winged monoplane, with wings based on those of the Lancair ES and a retractable tricycle landing gear from the Lancair IV. It has a steel-tube fuselage center section, with the remainder of the airframe of composite construction, and is designed to be powered by engines of 230–350 hp (172–261 kW). The recommended engine is the Continental IO-550, but engines as powerful as the Walter M601 have been used. It is available in two versions, the four seat ADI Stallion and the six-seat Super Stallion. Operational history Seven examples had been completed and flown by December 2007.
