The Ansaldo "Ballila" (Hunter) was amongst the fastest aircraft designed during the First World War, capable of achieving speeds of nearly 140 mph.  In addition to its great speed, the type was noted for its exceptional rate of climb.  The pilot was also allowed an excellent field of view due to the "V" shaped design of the plywood fuselage.

Despite being nearly 30 mph faster than any other fighter of the time, the aircraft was not well received by top Italian front line pilots who were invited to test fly and evaluate its performance.  It was said to lack maneuverability, and because of this, was never considered suitable for service at the front.  It was produced in limited quantities and was used primarily as a home defense fighter.

Poland purchased 34 of these aircraft, and a license from Ansaldo to produce an additional 60 aircraft for its air force between 1920 and 1924.

In 1992 Andy Keefe started construction of this reproduction aircraft after an original 160 hp Isotta-Fraschini engine was procured from the Caproni Collection in Italy.
