The Spezio Sport DAL 1 Tuholer is a two-place low-wing homebuilt aircraft using tube-and-fabric construction. A folding wing is incorporated to allow for trailering.[1]
Development
The prototype aircraft was built for $287 using tubing from a Cessna UC 78, a Tri-Pacer propeller, wheels from a TG-6 glider, a Lycoming Ground Power unit and a variety of surplus materials. The nickname came from the president of the Experimental Aircraft Association remarking that the plane was a "tuholer".[2] (Link does not work)>
Design
The Tuholer is a tandem two-seat, strut-braced, low-wing, open cockpit aircraft with conventional landing gear. The dual control aircraft can be flown solo from the front or rear cockpit.[3] The fuselage is welded steel tubing with wooden stringers and fabric covering.[4] The dual wing spars are wood, with wood ribs and fabric covering. The fuel tank is made of fiberglass. The horizontal stabilizer uses a Piper Cub style screw jack for trim. The rear headrest can be built streamlined flush with the vertical stabilizer or tapered.[5]
Operational history
The designer flew the prototype 16 years.
