Design and development

The DK 472 was a custom-designed engine that was part of the manufacturer's plan to build a mass-market paramotor. The DK 472 was supplanted by a single cylinder design and then, when the market never developed into the size envisioned by the company, all engine production was ceased in circa 2003.^[1][2][3]

The DK 472 is a twin cylinder, horizontally-opposed, air-cooled, two stroke engine that produces 22 hp (16 kW). Early versions were direct drive using a small diameter 29 in (74 cm) propeller. Later versions used a belt reduction drive system and a larger propeller. Electric start was standard equipment.^[1][3]
