While the company was in business the aircraft was supplied as a kit for amateur construction or as a complete ready-to-fly-aircraft.[1]

Design and development[edit]

The Lil Breezy was inspired by the similar RLU-1 Breezy and designed to comply with the United States FAR Part 103 Ultralight Vehicles rules in its single place version and also the US light-sport aircraft rules. It features a strut-braced high-wing, a single-seat or optionally a two-seats-in-tandem open cockpit without a windshield, fixed conventional landing gear and a single engine in pusher configuration.[1]

The early Lil Breezy-A is made from welded steel tubing with its flying surfaces covered in doped aircraft fabric. The later "B" model is of aluminium construction, with flying surfaces covered with Dacron sailcloth. Standard engines available included the 50 hp (37 kW) Rotax 503 two-stroke powerplant.[1]
