The Lucas L-6A, also called the L6A, is a French low-wing, two-seats in tandem motor glider that was designed by Emile Lucas of Lagny-le-Sec in the form of plans for amateur construction.[1][2][3][4]

Design and development

The L-6A was developed as a motor glider version of the Lucas L6 light aircraft.[1][2][3][4]

The L-6A is of all-metal construction. The 14 m (46 ft) span wing can be folded for ground transportation or storage and the wing tips are removable. The landing gear is of a retractable conventional landing gear configuration. The recommended engines are the Lycoming O-235 of 75 to 100 kW (101 to 134 hp) or the Limbach L2000 of 60 kW (80 hp).[1][2][3][4]

The L-6A was only available as plans and no kits or completed aircraft were factory-made. The plans cost US$400 in 2002 and at that time two examples were reported complete and flying. The construction time is estimated as 4000 hours.[1][2][3][4]
