Design and development

The G 4-2 R features a single main rotor, a two-seats-in tandem enclosed cockpit, tricycle landing gear and a four-cylinder, air and liquid-cooled, four-stroke, dual-ignition 100 hp (75 kW) Rotax 912S engine in pusher configuration. The 95 hp (71 kW) ULPower UL260i powerplant is optional.[1]

The aircraft fuselage is made with a stainless steel tube frame; the cockpit is formed from carbon fibre. Its 8.4 m (27.6 ft) diameter two-bladed aluminium Averso rotor employs a NACA 8H12 airfoil and has a 1500-hour time between overhauls. For safety the 35 litres (7.7 imp gal; 9.2 US gal) fuel tank incorporates ME Rin anti-explosion technology. A second fuel tank of the same capacity can be optionally added. Baggage capacity is two 21 litres (4.6 imp gal; 5.5 US gal) compartments. The aircraft has an empty weight of 262 kg (578 lb) and a gross weight of 450 kg (992 lb), giving a useful load of 188 kg (414 lb).[1][2]

Even though the manufacturer is an Austrian company the aircraft is built in Slovenia. The G 4-2 R was noted by Bayerl et al. in 2011 for its unusual new aircraft two-year warranty.[1]
