The Mathews Mr Easy is an American homebuilt aircraft that was designed by Lyle Mathews and associates and produced by the Vintage Ultralight and Lightplane Association of Marietta, Georgia. It was the sixth and final design of Mathews. The aircraft is supplied in the form of plans for amateur construction.Purdy, Don: AeroCrafter - Homebuilt Aircraft Sourcebook, Fifth Edition, page 286.

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 {{convert|254|lb|kg|0|abbr=on}}. The aircraft has a standard empty weight of {{convert|250|lb|kg|0|abbr=on}}.
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.
The aircraft is made from bolted-together aluminum tubing, with its flying surfaces covered in doped aircraft fabric. Its {{convert|24.00|ft|m|1|abbr=on}} span wing has a wing area of {{convert|145.0|sqft|m2|abbr=on}}. The standard engine used is the {{convert|40|hp|kW|0|abbr=on}} Rotax 447 two-stroke twin-cylinder powerplant.
Mr Easy has a typical empty weight of {{convert|250|lb|kg|abbr=on}} and a gross weight of {{convert|485|lb|kg|abbr=on}}, giving a useful load of {{convert|235|lb|kg|abbr=on}}. With full fuel of {{convert|5|u.s.gal}} the payload for the pilot and baggage is {{convert|205|lb|kg|abbr=on}}.
The standard day, sea level, no wind, take off and landing roll with a {{convert|40|hp|kW|0|abbr=on}} engine is {{convert|175|ft|m|0|abbr=on}}.
The designer estimates the construction time from the supplied plans as 250 hours.
Operational history
In the United States ultralights are not required to be registered, and in April 2014 no examples were in fact registered in the United States with the Federal Aviation Administration, although a total of two had been registered at one time.{{cite web|url = http://registry.faa.gov/aircraftinquiry/AcftRef_Results.aspx?Mfrtxt=&Modeltxt=MR+EASY&PageNo=1|title = Make / Model Inquiry Results|accessdate = 23 April 2014|last = Federal Aviation Administration|date = 23 April 2014}}
