After World War II, the Chief was introduced as the Model II AC. It was a variation of the Model 7 Champion and differed primarily by having increased fuselage width to permit side-by-side seating and a lowered cowling line to permit better visibility. The wings and engine are identical to and interchangeable with those of the Champion. The IIAC was powered by a 65 hp Continental. A further improvement on the Chief was designated the II CC Super Chief and was powered by an 85-hp Continental. It featured new balanced elevator surfaces to meet new trim requirements called for in the Civil Air Regulations. Its cruise speed was 95 mph, and its climb rate was 600 fpm. The Chief is the version that is still present in the greatest numbers.
