Design and development

The aircraft was designed to comply 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 250 lb (113 kg). [1]

Mr Easy features a strut-braced and cable-braced biplane layout, a single-seat, open cockpit, fixed conventional landing gear and a single engine in pusher configuration, mounted above the tail boom tube. [1]

The aircraft is made from bolted-together aluminum tubing, with its flying surfaces covered in doped aircraft fabric. Its 24.00 ft (7.3 m) span wing has a wing area of 145.0 sq ft (13.47 m2). The standard engine used is the 40 hp (30 kW) Rotax 447 two-stroke twin-cylinder powerplant. [1]

Mr Easy has a typical empty weight of 250 lb (110 kg) and a gross weight of 485 lb (220 kg), giving a useful load of 235 lb (107 kg). With full fuel of 5 U.S. gallons (19 L; 4.2 imp gal) the payload for the pilot and baggage is 205 lb (93 kg). [1]

The standard day, sea level, no wind, take off and landing roll with a 40 hp (30 kW) engine is 175 ft (53 m). [1]

The designer estimates the construction time from the supplied plans as 250 hours. [1]
