Developed by Giovanni Salsedo as a light sport aircraft, the Storm 280 SI was the first version of the Storm produced by SG Aviation, going into production in 1991. This was followed by the 280 G, a lighter, emergency parachute capable model to meet the German 450kg regulations. The Storm 300 Special introduced a new profile wing and an increase from 80hp to 100hp powerplant, allowing a higher cruise speed. Like its predecessor, it is available as a taildragger or tricycle undercarriage. The 300 Focus is the delux model with leather interior, adjustable rudder pedals, trim controls, and wheel covers. The Storm Century is a further development of the 300 with aerodynamic and engineering improvements. Distinguished by a longer engine cowl and wing tanks, it has higher weights (560kg MTOW), greater range, and a rear luggage compartment. A four seat development is also available, the 2+2 400 series (special and focus versions), and the larger 500 series which comes as a tricycle (500 CLK) or retractable undercarriage (500 SLK) version. The Storm is available built-up, as a quick-build kit, or as a standard kit.
