All G1 models have a fuselage made from welded steel tubing, with the wing made from aluminum, all covered in dopedaircraft fabric. The Gelinotte variant has a 9.9 m (32.5 ft) span wing with an area of 14.80 m2 (159.3 sq ft) and features leading edge slots. The SPYL model uses vortex generators in place of the slots, has the same wing span, but a slightly smaller wing area of 14.27 m2 (153.6 sq ft). All models are equipped with flaps and have optional folding wings for ground transport and storage. Standard engines available are the 60 kW (80 hp) Rotax 912UL and the 75 kW (101 hp) Rotax 912ULSfour-stroke powerplants. The company also offers a new exhaust system for the Rotax 912 that is quieter than the stock Rotax-supplied system.[1]
Wheel-equipped version introduced at the Aero show held in Friedrichshafen in 2010 and named for the two designers of the aircraft model, Serge Present and Yvan Lhermitte. The SPYL replaces the Gelinotte's wing, which is equipped with leading edge slots, with a new wing equipped with vortex generators instead. The new wing makes this model 20 kg (44 lb) lighter and 15%-20% faster than the Gelinotte. SPYL wings can be retrofitted to the Gelinotte.[1][2]
