About the Super Cyclone
The St-Just Aviation Intl Super Cyclone is a Canadian amateur-built fixed-wing aircraft featuring a four-seat enclosed cabin and a single tractor engine. Suited for utility and private construction, it follows a conventional layout with strut-braced high wings, a metal airframe, and interchangeable landing gear such as floats or skis.
Developed as an amateur-built replica based on established utility aircraft airframes, the design incorporates several structural enhancements including longer flaps and vertically hinged cabin access doors. Kits and plans have been distributed for home construction, and manufacturing responsibility eventually transitioned to a Washington-based company. Completed examples have been entered onto both Canadian and American civil registries.
