Replica Cessna 180-The St-Just Cyclone

By Willie Bodenstein

The Cessna 180 that had its first flight on 26 May 1952 was developed as a four- or six-seat general aviation airplane and was produced between 1953 and 1981. It gained recognition as the aircraft chosen by Geraldine Mock, the first woman pilot to successfully fly around the world. The flight was made in 1964 in her 1953 model, the Spirit of Columbus.

In 1992, forty years after the first Cessna 180 took to the sky St-Just Aviation of Mirabel, Quebec, Canada revealed it's St-Just Cyclone 180, a much improved kit plane designed for the home builders market.

The strut-braced high-wing Cyclone incorporated modifications and improvements, such as an extended wing span, greater wing area and vertically hinged doors. It features a four seat enclosed cabin accessed via doors, fixed conventional landing gear and a single 230 hp (172 kW) Continental O-470 engine in conventional tractor configuration.

The Cyclone is constructed using aircraft grade sheet aluminium, 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 aerofoil, mounts flaps and has a wing area of 181.00 sq ft (16.815 m2).

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