The Sky Arrow is based on the earlier, remotely piloted drones, the Rondine. The development of the proven airframe (with certification originally funded by the Italian government) into a series of sporting sircraft was undertaken, producing the Sky Arrow.
Guiseppe Archangeli made the first flight of the Sky Arrow from Ponzano, near Rome, on 13 July 1992. On that flight the prototype was fitted with the original metal wings, and it required only a 2 degree change in the tailplane incidence and minor mods to the controls.
To meet the civilian market demands and regulations, the Sky Arrow has been modified from the original concept, with the initial design studies being wind tunnel tested at the University. The original metal wings have been substituted with an all composite version.
The Sky Arrow 450T is a single-engine aircraft with vertically staggered tandem seats and dual controls. The instrument panel is located ahead of the front seat, and all the instruments are arranged to allow visibility from the rear seat, which is elevated somewhat in relation to the front seat. However, wing flaps, dual electronic switches and cabin heat can only be operated from the front seat. Operable from both seats are the brakes, trim, mixture control and carburettor air control.

The high wings are braced and rectangular in shape, and are made of a carbon-fibre sandwich with kevlar reinforcement, while the struts are constructed of alu¬minium and steel. The Sky Arrow 450 T wings are the as as the P92. The fuselage and empennage are made from carbon-fibre and kevlar. Landing gear is a fixed tricycle-type constructed of multilayered carbon-fibre and rubber shock absorbers for the nose gear. Load factor limits at a planned maximum all up weight of 450kg are +3.8G/-1.9G, with an ultimate strength of +7.6G/-3.8G before breakage occurs. The aeroplane is powered by an 80 hp four-stroke Rotax 912 engine, coupled by means of a reduction gear¬box with a ratio of 1:227 driving a two-bladed propeller.
The airframe is fully manufactured with composite materials (kevlar and carbon sandwich). The high-wing tandem configuration provides excellent visibility of over 300degrees. The Sky Arrow is fitted with either a Rotax 912 or 914 engine. The aircraft is offered to homebuilder enthusiasts as a kit which meets the FAA 49/51 percent rule. The Sky Arrow kit is composed of 10 subkits which can be bought separately and incrementally.

The Sky Arrow 450 and 650 are the same aircraft available as certified and ultralight versions. Easily converted to wheels, floats or amphibian, the 650TC is certified to JAR/VLA standard. Both the 450T ULM and 650T kit are built to that standard.

In 2014, the Sky Arrow 600 was manufactured by Italian maker Magnaghi. Base price 2014: $87,000 (Sky Arrow); $100,000 (loaded with SkyView 10-inch EFIS for limited time).
