The Arplast Micro'B (English: Microbe) is a French ultralight aircraft that was designed and produced by propeller manufacturer Arplast Helice. It was supplied as a kit for amateur construction or as a complete ready-to-fly-aircraft.[1]
Design and development
The Arplast Micro'B was designed to comply with the Fédération Aéronautique Internationale microlight rules, with a lightened version for the US FAR 103 Ultralight Vehicles category. It features a strut-braced high-wing, a single-seat enclosed cockpit, fixed tricycle landing gear and a single engine in tractor configuration.[1]
The Micro'B is made from a combination of welded steel and carbon fibre, with the flying surfaces made from the latter material.

Standard engines included the 40 hp (30 kW) Rotax 447 two-stroke or other small lightweight motors, mounted on the main keel tube above the cockpit.[1]
