The St-Just Cyclone, also called the St-Just Cyclone 180, is a Canadian homebuilt aircraft that was designed and produced by St-Just Aviation of Mirabel, Quebec. The company has since moved to Boucherville, Quebec. While it was available the aircraft was supplied as a kit and in the form of plans for amateur construction.

The Cyclone was later developed into the higher gross weight (3,500 lb (1,600 kg)) St-Just Super-Cyclone, which superseded it in production.

Design and development

The Cyclone is a replica of the Cessna 180 that incorporates modifications and improvements, such as an extended wing span, greater wing area and vertically hinged doors. It features a strut-braced high-wing, a four seat enclosed cabin accessed via doors, fixed conventional landing gear and a single engine in tractor configuration.

The aircraft is made from sheet aluminum, with the kit airframe parts preformed with pilot holes to allow construction without the use of jigs. Its 38.00 ft (11.6 m) span wing employs a NACA 2412 airfoil, mounts flaps and has a wing area of 181.00 sq ft (16.815 m2). The acceptable power range is 200 to 250 hp (149 to 186 kW) and the standard engine used is the 230 hp (172 kW) Continental O-470.

The Cyclone has a typical empty weight of 1,700 lb (770 kg) and a gross weight of 3,000 lb (1,400 kg), giving a useful load of 1,300 lb (590 kg).

The manufacturer estimated the construction time from the supplied kit as 2000 hours.

Operational history

In December 2013, 23 examples were registered in Canada with Transport Canada and three in the United States with the Federal Aviation Administration.
