Robert O. Schertz



"Aircraft Adapted for Highway Usage"


On March 5 of 1968 Robert O. Schertz of El Paso, Illinois
Was granted patent #3,371,886 to protect this design.




The machine had a canard configuration with removable forward horizontal stabilizers and with rear foldable wings. It also had a side-opening cabin door between the stabilizers and the wings. The purpose of this arrangement was to allow access in the normal manner of a two-door car, without having to climb over the wing structure. The engine was at the rear over the wings, and was to be used to provide power to the prop for flight and to the wheels for road travel. Controls were also designed for use in flight and highway driving.




It had powered rear wheels for highway use, and all four wheels could be retracted when the vehicle was in flight.

Wing design was unique. Each of the wings extended from a wing-root structure at the rear of the fuselage where a vertical stabilizer and rudder were mounted on each side.

Outboard from that assembly each wing consisted of two panels.

The first step in folding the wings was to unlock the panels and fold the outer one in on top of the inner panel. Next, the two were folded up beside the vertical stabilizer to create a kind of panel sandwich.

One of the removable canards could then be stowed inboard of each of the vertical stabilizers, or if preferred, they could be stowed behind the rear seats in the cabin.
