The St-Just Super-Cyclone is a Canadian amateur-built aircraft produced by St-Just Aviation of Boucherville, Quebec. The aircraft is supplied as plans or as a kit for amateur construction.

Design and development

The Super-Cyclone is a development of the earlier St-Just Cyclone and is based on the Cessna 180 and Cessna 185 airframe design. The kit manufacturer terms it "a replica" of the Cessna designs. Like the 180/185 it features a strut-braced high-wing, a four-seat enclosed cabin accessed via doors, fixed conventional landing gear, skis or floats and a single engine in tractor configuration.

The aircraft is made from sheet 2024-T3 aluminum, with some parts made from 6061-T6 and 7075-T6. Its 38.1 ft (11.6 m) extended-span wing employs a NACA 2412 airfoil, has an area of 191 sq ft (17.7 m2) and mounts large slotted flaps. The aircraft can be equipped with engines ranging from 200 to 350 hp (149 to 261 kW). The standard engine used is the 300 hp (224 kW) Continental IO-520 four-stroke powerplant. The design includes improvements over the Cessna, including vertically hinged doors and longer span flaps combined with shorter span ailerons, in a similar manner to the Cessna 206.

Operational history

In March 2017 there were seven Super-Cyclones on the Transport Canada Civil Aircraft Register and one registered with the US Federal Aviation Administration.
