The Duster D-1 was conceived by Merle Larson of the Larson Aero Development company in the mid-1950s as a potential replacement for the usual modified types employed for agricultural purposes, Stearmans mainly. More efficiently built than those Stearmans, its wings were aluminium-covered and had the usual steel-tube fuselage. The latter, as we can see, had only the forward part fabric-covered. The reason: to prevent dust buildup inside the tail. Standard automotive (Ford) wheels and tires were employed to reduce cost.
It had no takers. Only this very convincing prototype was built with those magnificent “all-flying” rudders.
