Design and development

The Explorer I was designed as a low-cost utilitarian autogyro. It complies with the US FAR 103 Ultralight Vehicles rules, including the category's maximum empty weight of 254 lb (115 kg). The aircraft has a standard empty weight of 254 lb (115 kg). It features a single main rotor, a single-seat open cockpit without a windshield and conventional landing gear. A cockpit fairing was a factory option. The acceptable power range is 45 to 65 hp (34 to 48 kW) and the standard engine used is the twin cylinder, air-cooled, two-stroke, single-ignition 45 hp (34 kW) 2si 460 engine in tractor configuration. The cabin width is 28 in (71 cm). [1]

The aircraft fuselage is made from a combination of welded 4130 steel tube and bolted-together aluminum tubing. Its two-bladed rotor has a diameter of 23 ft (7.0 m). The aircraft has a typical empty weight of 254 lb (115 kg) and a gross weight of 564 lb (256 kg), giving a useful load of 310 lb (140 kg). With full fuel of 5 U.S. gallons (19 L; 4.2 imp gal) the payload for the pilot and baggage is 280 lb (130 kg). [1]

The standard day, sea level, no wind, take off with a 45 hp (34 kW) engine is 250 ft (76 m) and the landing roll is 50 ft (15 m). [1]

The manufacturer estimated the construction time from the supplied kit as 100 hours. [1]
