A fixed-wing four-to-six-seat light aircraft that can be easily converted to a roadway vehicle within minutes by a single person in the field, comprising a one-piece wing center panel with foldable wing tips on each sides. The whole wing unit is then rotatably mounted on top of the fuselage. The aircraft features a conventional front-engine-and-propeller lay-out, with a foldable tail section for convenient roadability and garageability. All the wheels are retractable in flight, and it has a long-span, high aspect-ratio wing for exceptional climb and cruise efficiency. The vehicle has a low ride-height with a low center of gravity, four wheels with independent suspension, nose-height leveling for take-off and landing, and anti-sway mechanism for good ground handling ability. Ground propulsion is by automotive-style transmission driving the rear wheels or by hydraulic motors in the all-wheel retractable version.

[ What is claimed is:] [1.] In a roadable fixed-wing flying vehicle designed to operate effectively both in the air and in the roadway, said vehicle having a center of gravity, a longitudinal axis, a fuselage, a width, a top, a front section, a center section with a rear end, and a tail section, the
[ What is claimed is:] [1.] In a roadable fixed-wing flying vehicle designed to operate effectively both in the air and in the roadway, said vehicle having a center of gravity, a longitudinal axis, a fuselage, a width, a top, a front section, a center section with a rear end, and a tail section, the combination comprising:ground-supporting system having a front ground-supporting means disposed at the front section of the vehicle, and a rear ground-supporting means mounted behind the center of gravity,an air-propulsion means for propelling said vehicle while flying in the air,a wing fixedly mounted to the fuselage in flight, said wing having wing-folding means allowing said wing to retract to a narrow width suitable for roadway traveling,a horizontal stabilizer means disposed at the tail section of the fuselage, comprises of at least one elongated horizontally oriented surface having two opposite ends each thereof is disposed on each side of the longitudinal axis of the vehicle,a vertical stabilizer means comprises of at least two vertically oriented surfaces each thereof is mounted onto said horizontally oriented surface on each side of the longitudinal axis,a tail-folding means wherein said tail section of the fuselage is pivotably mounted to the rear end of said center section of the fuselage, allowing the tail section of the fuselage to pivot forward and backward in a vertical plane parallel to the longitudinal axis of the vehicle at an approximately 180-degree arc, between an extended position for flying wherein said tail section trails the rear end of said center section of the fuselage, and a folded position for roadability wherein said tail section is folded overlapping a portion of the center section of the fuselage, thereby allowing the fuselage to be considerably shortened for roadway operation yet still keeping said horizontal stabilizer generally parallel chordwise to the longitudinal axis of the vehicle in order to minimize aerodynamic drag in the roadable mode, said tail-folding means is comprised of:hinge means disposed on an upper corner of the rear end of the center section of the fuselage for connecting the tail section to the center section of the fuselage, allowing said pivoting motion of the tail section with respect to the center section,locking means for releasably locking said tail section of the fuselage in said extended position for flying, and,securing means for releasably securing said tail section of the fuselage in said folded position for roadway operation.
