The L-6B is a sport touring aircraft derived from the Lucas L6 and Lucas L-6A. It features a cantilever low-wing, a two-seats-in-tandem enclosed cockpit under a bubble canopy, retractable tricycle landing gear and a single engine in tractor configuration. It is noted for its high service ceiling of 60960NaN0 and 17700NaN0 range.
The aircraft is made from sheet aluminum. Its 8.841NaN1 span wing mounts flaps and has a wing area of 13.010NaN0. The wing is a complex shape with a swept wing root, transitioning to a forward swept leading edge, with a straight tapered trailing edge, resulting in a highly tapered wing planform. The outer wing section can be folded for ground transport or storage. There are optional additional span wing tip extensions to increase glide performance. The cabin width is 71cm (28inches) and fuel tanks are located in the wing leading edge. The acceptable power range is 108to and the standard engines used are the 1080NaN0 Lycoming O-235 and the 1800NaN0 Lycoming O-360 powerplant.
The L-6B has a typical empty weight of 481kg (1,060lb) and a gross weight of 721kg (1,590lb), giving a useful load of 240lb. With full fuel of the payload for the pilot, passengers and baggage is 131lb.
The manufacturer estimated the construction time from the supplied kit as 4000 hours.
By 1998 the company reported that five kits had been sold and two aircraft were completed and flying.
