He reduced the wing area and aspect ratio and strengthened its structure, and modified the tail to act in the conventional way. He also upgraded the power train, replacing the ignition and cooling systems and fitting new propellers designed after the Wright pattern.
To improve performance, he reduced the wing size and shape, reinforced the aircraft's structure, and adjusted the tail for standard flight characteristics.  He also replaced the engine components with a more efficient setup, including new propellers based on Wright's original designs.
