The Light Miniature Aircraft LM-1, LM-2 and LM-3 are a family of American high wing, conventional landing gear, strut-braced, single engine ultralight aircraft that are scale reproductions of famous general aviation aircraft. The designs were all available as plans from Light Miniature Aircraft of Okeechobee, Florida for amateur construction.[1][2][3]

The Light Miniature Aircraft company website domain name expired on 25 May 2010 and has not been renewed.[4] The company seems to have gone out of business about 2010, but Wicks Aircraft continued to provide kits for the designs for a period of time afterwards, although, as of 2022, they no longer do so.[5][6]

Design and development

[edit]

The LM-1 family were designed in the mid-1980s during the initial ultralight boom. Many pilots did not find the typical early ultralights that resemble a "flying lawnchair", such as the Pterodactyl Ascender or Eipper Quicksilver confidence inspiring or appealing. The LM line was intended to fit the same FAR Part 103 rules, including its 254 lb (115 kg) empty weight, but provide an aircraft that looks and flies much more like a traditional light aircraft. Many of the family are heavier than the US ultralight rules permit.[2]

The LM-1 family consists of a basic aircraft design, rendered in wood or optionally 4130 steel tube, with minor changes in the cowling, window and tail shapes to make them resemble well-known light aircraft. The first in the series, the LM-1 was first flown in 1985. The aircraft are sold as plans, with components or complete kits also available to speed construction time.[1][2][3]

All aircraft in the series feature enclosed cabins allowing year-round flying, docile handling characteristics and a 300-hour construction time.[2]
