St-Just Super-Cyclone Explained

The St-Just Super-Cyclone is a Canadian amateur-built aircraft that was at one time produced by St-Just Aviation of Boucherville, Quebec. By 2023 production had passed to Bushliner Aircraft Manufacturing of Granite Falls, Washington who were building it as the Bushliner 1850EX. The aircraft is supplied as plans or as a kit for amateur construction.^{[1] [2] [3] [4] [5]}

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.^{[1] [3] [4] [6]}

The aircraft is made from sheet 2024-T3 aluminum, with some parts made from 6061-T6 and 7075-T6. Its 38.11NaN1 extended-span wing employs a NACA 2412 airfoil, has an area of 191square feet and mounts large Fowler flaps. The aircraft can be equipped with engines ranging from 200to. The standard engine used is the 3000NaN0 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.^{[1] [3] [6] [4] [7]}

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.^{[8] [9]}
