Design and development
The L.S.5 was a modification to the Standard J Biplane. The aircraft featured an engine upgrade to 150 hp from the original Curtiss OX-5 engine and a modification to the fuselage to seat four passengers in an unusually deep open cockpit layout with side-by-side configuration seating facing each other.

Mexican aviator Emilio Carranza purchased and flew a L.S.5, named "Excelsior", making flights that earned him the reputation of "The Lindbergh of Mexico" in 1927. It crashed on July 12, 1928, killing Carranza, on a return flight from New York.
