Spezio DAL-1 Tuholer


The Spezio DAL-1 Tuholer stems from a design by Tony Spezio in the late 1950s and is said to have been based loosely on the Howard Ike racer of the 1930s. As the Tulioler name implies, it is a two-seat, open cockpit, strutbraced, low-wing taildragger. The original was built using parts collected from various surplus and wrecked sources, and with no hangar space the wings were designed to fold. The first flight of the type occurred on 02-05-1961.
The fuselage and tail structure are welded steel tubing. Its large center section, supporting the folding wing mechanism is fashioned from a trio of one-inch .049 tub-ing with end plates, fittings and large bolts that allow the wings to fold for storage.
