Plans are supplied by one of the first builders of the type, Roland Mangeard of Pulnoy.
[1][2] The aircraft was designed to comply with the Fédération Aéronautique Internationale microlight rules.
It features a cantilever low-wing, a two-seats-in-side-by-side configuration enclosed cockpit under an aircraft canopy with gull winged doors for access, fixed conventional landing gear and a single engine in tractor configuration.
The Autoplum's tailplane is 50% the area of the main wing, which provides a wide centre of gravity range and a high degree of pitch dampening.
Earlier examples were fitted with a 51 hp (38 kW) Rotax 462 two-stroke engine, with later ones using the 64 hp (48 kW) Rotax 582 two-stroke powerplant or other engines.
