As a result of its test flying of this prototype, however, the Royal Air Force requested greater wing incidence: Short had selected an incidence of 3° for the best possible cruise performance, but the RAF was more concerned with improved take-off performance and asked for the incidence angle to be increased to 6,5°. This was a major redesign, however, requiring time-consuming revision of the central fuselage, so the compromise reached was a considerable lengthening of the main landing gear legs to given a higher ground angle.
