Ultralight aviation (called microlight aviation in some countries) is the flying of lightweight, 1- or 2-seat fixed-wing aircraft. Some countries differentiate between weight-shift control and conventional three-axis control aircraft with aile ...

, ply and fabric construction. It was designed by C.H. Latimer-Needham, and built by Luton Aircraft at Barton-in-the-Clay, Bedfordshire in 1936, using the fuselage and components of the earlier experimental L.A.2 tandem-wing aircraft. The prototype L.A.3 Minor, registered ''G-AEPD'', first flew on 3 March 1937 at Heston Aerodrome.Smith (2002) The aircraft was a successful flyer despite the low-powered engine, and it was then redesigned for home construction. Designated the L.A.4 Minor, it had a strutted undercarriage and parallel wing struts. The first L.A.4 Minor was built at the company's new factory (the Phoenix Works) at Gerrards Cross in Buckinghamshire. It was fitted with a 40 hp ABC Scorpion two-cylinder horizontally-opposed engine. All subsequent Luton Minors were home-built from plans sold by the company.

Operational history
Reviewers Roy Beisswenger and Marino Boric described the design in a 2015 review, saying, "it has a great deal of period charm and gives a back-to-basics feel, although performance doesn't match more modern designs. Predictable handling and sturdy construction make it a joy to own. A white scarf is a compulsory accessory.".Variants
