The J4 was designed to comply with the Fédération Aéronautique Internationale microlight rules and US light-sport aircraft rules. It features a strut-braced high-wing, a two-seats-in-side-by-side configuration enclosed cabin accessed by doors, fixed tricycle landing gear and a single engine in tractor configuration.^[1]
