The modified Wright Model B Flyer was the first aircraft model produced in quantity by the Wright brothers. It was one of the planes used for training by the U.S. Signal Corps. It was a standard biplane and could seat a pilot and one passenger.

The modified Wright Model B had a wingspan of 39 feet (11.9 meters), a length of 28 feet (8.5 meters), and stood 8 feet, 9 inches (2.7 meters) high. It was powered by an eight-cylinder 75-horsepower (56-kilowatt) Rausenberger engine, which was its major change from the original Model B, which was powered by a four-cylinder Wright engine. It also used ailerons on the training edges of the wings in place of the Wright's lever control system. It could attain a maximum speed of 45 miles per hour (72 kilometers per hour).

The original Model B introduced the four-wheel landing gear and rear-mounted elevators, replacing the earlier skids and forward elevators.
