The aircraft is supplied as a kit for amateur construction or complete and ready-to-fly. It was developed from the similar Remos Gemini Ultra. The Mirage has the same layout, landing gear and structure but has a span reduced by 1.00 m (3 ft 3 in), is 170 mm ( 6.7 in) longer and is 34 kg (75 lb) heavier. The Mirage also adds an elevator trim tab and electrical flap operation. The Gemini's standard two-stroke 48 kW (64 hp) Rotax 582 engine was replaced in the Mirage by a 60 kW (80 hp) four-stroke Rotax 912UL. The G3 Mirage first flew on 20 September 1997 with the lower powered Rotax. The first production aircraft also used this engine but had some small horizontal control surface modifications plus the addition of a horn balance to the rudder. The GX has been the current production model since 2006 and features folding wings and monocoque carbon fiber construction. Its wing has a different airfoil than the G3, improving roll rate and giving better penetration of turbulence. The GX is fitted with either a Junkers or BRS ballistic parachute recovery system.
