Gemini Sparkle

Key Takeaways:

  • The Hatz is a tandem, two-seat, open cockpit biplane that first flew in 1968, notably being the lightest two-place biplane available with an empty weight of 850 pounds.
  • It features fabric-covered wooden wings and a welded-steel tubing fuselage, performing well with 85-hp engines and stressed to accommodate up to 150 hp.
  • Known for its slow control response, it can be trimmed to fly hands-off, giving a feel of a larger aircraft, and is capable of all aerobatic maneuvers within its power range.

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.
