09/30/2008. Remarks by Johan Visschedijk: "Design of this small single-seat agricultural aircraft was started on October 1, 1964, and three prototypes were planned. The first Mamboretá (Praying Mantis) was used for static and fatigue testing, the second made its first flight on November 10, 1966, registered as LV-X-33, while reportedly the third never flew. The aircraft had a provision for a second person to be seated in tandem on ferry flights, and was powered by a 235 hp Lycoming O-540-B2B5 six-cylinder horizontally-opposed air-cooled engine.
Although generally considered better and stronger compared to the Cessna A188 AgTruck that was also produced by DINFIA, the planned production of 300 examples never materialized as the company was to occupied with the manufacturing of the I.A.50 Guaraní II and the preparations for the IA 58 Pucará (Fortress). The sole prototype was transferred to the Argentine AF in 1971, serialed PGAX-01, and used as a glider tug and for other utility duties. Presently it is preserved at the Museum."
