The Remos G3 Mirage and Remos GX are variants of a high wing, two seat, single engine light aircraft, built in Germany and sold world wide. The Remos GX has been the current model since 2006.

Design and development[edit]

The aircraft is marketed in the United States as a Light Sport Aircraft, and as an ultralight in most of Europe. It is a high-wing design, mostly using engines from the Rotax 912 family.[1] 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.[2]

The wings of the G3 Mirage have a constant chord centre section with straight tapered outer panels. The inboard sections carry electrically operated flaps. There is a single lift strut on each side, attached to the lower fuselage. Behind the cabin the fuselage is slender and carries a low set, straight tapered tailplane with horn balanced elevators. The fin and rudder are straight edged and sharply tapered, the latter horn balanced and ending at the top of the fuselage. There is a small underfin.[1][3] The GX version introduced a long, integrated dorsal fin. The G3 Mirage has a tricycle undercarriage with cantilever legs mounted to the fuselage and with faired wheels.[1]

The prototype and most production Mirages have been powered by 80 hp or 100 hp variants of the Rotax 912 flat four engine. The Mirage RS/L version had a Jabiru 2200 and one aircraft (D-MPCJ) had a two cylinder, 72 hp Swiss Auto SAB 430 turbocharged car engine, which saved 30 kg (66 lb).[1]

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.[1]

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.[1]

The GX2009 was introduced at the Sebring Expo. There were improvements to the instrument panel and interior and a new chromoly steel tube landing gear, which replaced the earlier composite undercarriage, is retrofitable to older models.[4]

Operational history[edit]

Remos GXs over the seaport of Saint-Petersburg, Russia

The G3 Mirage/GX has been produced to meet both European ultralight and US LSA regulations. By early 2009 over 300 of all variants had been sold world wide.[1] About half were in Europe: in mid-2010 there were 156 G3 and GX aircraft on European civil registers west of Russia.[5] [6] The rest went to countries including New Zealand, Thailand and the USA. Mirages were also sold to police forces in Argentina and to a military agency in Romania.[1]

An analysis of the operating economics by Aviation Consumer magazine of the G3 versus the Cessna 152 in flight school use during 2013 showed that the G3 cost 50% more to operate than the thirty year old Cessna did.[7]
