The first flight of this tandem, two-seat, and open cockpit biplane took place in 1968. The wings are a fabric-covered wooden structure, while the fuselage is built from welded-steel tubing. The design weight of the Hatz (850 pounds) makes it the lightest two-place biplane available. It performs well with the 85-hp Continental and is stressed to take engines up to 150 hp. The Hatz can be trimmed to fly hands off (more or less), which helps out when trying to read a map in an open cockpit. Control response is slow enough to give a feeling of a much larger aircraft, and it is capable of all aerobatic maneuvers in its power range.
