The Lucas L7, also called the L 7 and L-7, is a French amateur-built aircraft that was designed by Emile Lucas of Lagny-le-Sec. The aircraft is supplied in the form of plans for amateur construction.
Design and development
The L7 features a strut-braced high-wing, a two-seats-in-side-by-side configuration enclosed cockpit with doors for access, fixed main tricycle landing gear with a retractable nosewheel and a single engine in tractor configuration.
The aircraft is made from sheet aluminum. Its 10 m (32.8 ft) span wing has an area of 12 m (130 sq ft) and mounts both flaps and leading edge slots for STOL performance. The standard engine used is the 118 hp (88 kW) Lycoming O-235 four-stroke powerplant which provides a cruise speed of 175 km/h (109 mph).
Reviewers Roy Beisswenger and Marino Boric described the design in a 2015 review as have a "somewhat boxy shape".
