 Sack blamed the problem of insufficient angle of attack, but Baltabol believed it to be lack of power, and suggested that the AS-6 be fitted with a 2,000 hp Daimler-Benz DB 605 engine from a Bf 109.Sack, convinced it was the angle of attack that was the problem, relocated the landing gear eight inches aft.This, too, was insufficient, and some sources claim that the landing gear was relocated a further 16 inches aft, but this is unlikely.
