The U.S. Airplane Co.'s "L.C.7." built by the U.S. Airplane and Motor Engineering Co., of Upper Sandusky, Ohio.

  The "L.C.7" is a small tractor biplane constructed on more or less conventional lines. In its present form it is fitted with a 42 h.p. engine, but it is intended to fit 60 h.p. engines to all the future models. There are several novel features in the construction of this machine of considerable importance in a sporting machine, such as the absence of turnbuckles in the fuselage, and the employment of rods in place of cables for the controls. This form of control not only makes for greater safety and strength, but also reduces head resistance.
  Another feature is the covering of the forward cock-pit, which allows the carrying of packages or parcels when a passenger is not carried. When a passenger is taken, the cover is removed and a portable seat, which is provided with the machine, is attached to the seat rails.
