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.Purdy, Don: AeroCrafter - Homebuilt Aircraft Sourcebook, Fifth Edition, page 126. BAI Communications, 15 July 1998. {{ISBN|0-9636409-4-1}}
The Cyclone was later developed into the higher gross weight ({{convert|3500|lb|kg|abbr=on}}) St-Just Super-Cyclone, which superseded it in production.
In 2021, the rights to the Cyclone aircraft were acquired by Bushliner Aircraft LLC of Granite Falls, WA.
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 {{convert|38.00|ft|m|1|abbr=on}} span wing employs a NACA 2412 airfoil, mounts flaps and has a wing area of {{convert|181.00|sqft|m2|abbr=on}}. The acceptable power range is {{convert|200|to|250|hp|kW|0|abbr=on}} and the standard engine used is the {{convert|230|hp|kW|0|abbr=on}} Continental O-470.
The Cyclone has a typical empty weight of {{convert|1700|lb|kg|abbr=on}} and a gross weight of {{convert|3000|lb|kg|abbr=on}}, giving a useful load of {{convert|1300|lb|kg|abbr=on}}.
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.{{cite web|url = http://wwwapps2.tc.gc.ca/Saf-Sec-Sur/2/ccarcs/aspscripts/en/quicksearch.asp|title = Canadian Civil Aircraft Register|accessdate = 16 December 2013|last = Transport Canada|date = 16 December 2013|url-status=dead|archiveurl = https://web.archive.org/web/20110718042755/http://wwwapps2.tc.gc.ca/Saf-Sec-Sur/2/ccarcs/aspscripts/en/quicksearch.asp|archivedate = 18 July 2011}}{{cite web|url = http://registry.faa.gov/aircraftinquiry/AcftRef_Results.aspx?Mfrtxt=&Modeltxt=CYCLONE&PageNo=1|title = Make / Model Inquiry Results|accessdate = 16 December 2013|last = Federal Aviation Administration|date = 16 December 2013}}
